pub struct LocalRequest<'c> { /* private fields */ }
Expand description

A blocking local request as returned by Client.

For details, see the top-level documentation.

Example

The following snippet uses the available builder methods to construct and dispatch a POST request to / with a JSON body:

use rocket::local::blocking::{Client, LocalRequest};
use rocket::http::{ContentType, Cookie};

let client = Client::tracked(rocket::build()).expect("valid rocket");
let req = client.post("/")
    .header(ContentType::JSON)
    .remote("127.0.0.1:8000".parse().unwrap())
    .cookie(Cookie::new("name", "value"))
    .body(r#"{ "value": 42 }"#);

let response = req.dispatch();

Implementations§

source§

impl<'c> LocalRequest<'c>

source

pub fn inner(&self) -> &Request<'c>

Borrows the inner Request as seen by Rocket.

Note that no routing has occurred and that there is no remote address unless one has been explicitly set with set_remote().

Example
use rocket::local::blocking::LocalRequest;

let request: LocalRequest = request;
let inner: &rocket::Request = request.inner();
source

pub fn inner_mut(&mut self) -> &mut Request<'c>

Mutably borrows the inner Request as seen by Rocket.

Note that no routing has occurred and that there is no remote address unless one has been explicitly set with set_remote().

Example
use rocket::local::blocking::LocalRequest;

let mut request: LocalRequest = request;
let inner: &mut rocket::Request = request.inner_mut();
source

pub fn header<H>(self, header: H) -> Selfwhere H: Into<Header<'static>>,

Add a header to this request.

Any type that implements Into<Header> can be used here. Among others, this includes ContentType and Accept.

Examples

Add the Content-Type header:

use rocket::local::blocking::LocalRequest;
use rocket::http::Header;
use rocket::http::ContentType;

let request: LocalRequest = request;
let req = request
    .header(ContentType::JSON)
    .header(Header::new("X-Custom", "custom-value"));
source

pub fn add_header<H>(&mut self, header: H)where H: Into<Header<'static>>,

Adds a header to this request without consuming self.

Examples

Add the Content-Type header:

use rocket::local::blocking::LocalRequest;
use rocket::http::ContentType;

let mut request: LocalRequest = request;
request.add_header(ContentType::JSON);
source

pub fn remote(self, address: SocketAddr) -> Self

Set the remote address of this request.

Examples

Set the remote address to “8.8.8.8:80”:

use rocket::local::blocking::LocalRequest;

let request: LocalRequest = request;
let address = "8.8.8.8:80".parse().unwrap();
let req = request.remote(address);
source

pub fn cookie(self, cookie: Cookie<'_>) -> Self

Add a cookie to this request.

Examples

Add user_id cookie:

use rocket::local::blocking::LocalRequest;
use rocket::http::Cookie;

let request: LocalRequest = request;
let req = request
    .cookie(Cookie::new("username", "sb"))
    .cookie(Cookie::new("user_id", "12"));
source

pub fn cookies<'a, C>(self, cookies: C) -> Selfwhere C: IntoIterator<Item = Cookie<'a>>,

Add all of the cookies in cookies to this request.

Example
use rocket::local::blocking::LocalRequest;
use rocket::http::Cookie;

let request: LocalRequest = request;
let cookies = vec![Cookie::new("a", "b"), Cookie::new("c", "d")];
let req = request.cookies(cookies);
Available on crate feature secrets only.

Add a private cookie to this request.

Examples

Add user_id as a private cookie:

use rocket::local::blocking::LocalRequest;
use rocket::http::Cookie;

let request: LocalRequest = request;
let req = request.private_cookie(Cookie::new("user_id", "sb"));
source

pub fn body<S: AsRef<[u8]>>(self, body: S) -> Self

Sets the body data of the request. core/lib/src/local/request.rs

Examples
use rocket::local::blocking::LocalRequest;
use rocket::http::ContentType;

let request: LocalRequest = request;
let req = request
    .header(ContentType::Text)
    .body("Hello, world!");
source

pub fn set_body<S: AsRef<[u8]>>(&mut self, body: S)

Set the body (data) of the request without consuming self.

Examples

Set the body to be a JSON structure; also sets the Content-Type.

use rocket::local::blocking::LocalRequest;
use rocket::http::ContentType;

let request: LocalRequest = request;
let mut request = request.header(ContentType::JSON);
request.set_body(r#"{ "key": "value", "array": [1, 2, 3] }"#);
source

pub fn dispatch(self) -> LocalResponse<'c>

Dispatches the request, returning the response.

This method consumes self and is the preferred mechanism for dispatching.

Example
use rocket::local::blocking::LocalRequest;

let request: LocalRequest = request;
let response = request.dispatch();

Methods from Deref<Target = Request<'c>>§

source

pub fn method(&self) -> Method

Retrieve the method from self.

Example
use rocket::http::Method;

assert_eq!(get("/").method(), Method::Get);
assert_eq!(post("/").method(), Method::Post);
source

pub fn set_method(&mut self, method: Method)

Set the method of self to method.

Example
use rocket::http::Method;

assert_eq!(request.method(), Method::Get);

request.set_method(Method::Post);
assert_eq!(request.method(), Method::Post);
source

pub fn uri(&self) -> &Origin<'r>

Borrow the Origin URI from self.

Example
assert_eq!(get("/hello/rocketeer").uri().path(), "/hello/rocketeer");
assert_eq!(get("/hello").uri().query(), None);
source

pub fn set_uri(&mut self, uri: Origin<'r>)

Set the URI in self to uri.

Example
use rocket::http::uri::Origin;

let uri = Origin::parse("/hello/Sergio?type=greeting").unwrap();
request.set_uri(uri);
assert_eq!(request.uri().path(), "/hello/Sergio");
assert_eq!(request.uri().query().unwrap(), "type=greeting");

let new_uri = request.uri().map_path(|p| format!("/foo{}", p)).unwrap();
request.set_uri(new_uri);
assert_eq!(request.uri().path(), "/foo/hello/Sergio");
assert_eq!(request.uri().query().unwrap(), "type=greeting");
source

pub fn host(&self) -> Option<&Host<'r>>

Returns the Host identified in the request, if any.

If the request is made via HTTP/1.1 (or earlier), this method returns the value in the HOST header without the deprecated user_info component. Otherwise, this method returns the contents of the :authority pseudo-header request field.

Note that this method only reflects the HOST header in the initial request and not any changes made thereafter. To change the value returned by this method, use Request::set_host().

⚠️ DANGER ⚠️

Using the user-controlled host to construct URLs is a security hazard! Never do so without first validating the host against a whitelist. For this reason, Rocket disallows constructing host-prefixed URIs with uri!. Always use uri! to construct URIs.

Example

Retrieve the raw host, unusable to construct safe URIs:

use rocket::http::uri::Host;

assert_eq!(request.host(), None);

request.set_host(Host::from(uri!("rocket.rs")));
let host = request.host().unwrap();
assert_eq!(host.domain(), "rocket.rs");
assert_eq!(host.port(), None);

request.set_host(Host::from(uri!("rocket.rs:2392")));
let host = request.host().unwrap();
assert_eq!(host.domain(), "rocket.rs");
assert_eq!(host.port(), Some(2392));

Retrieve the raw host, check it against a whitelist, and construct a URI:

use rocket::http::uri::Host;

// A sensitive URI we want to prefix with safe hosts.
#[get("/token?<secret>")]
fn token(secret: Token) { /* .. */ }

// Whitelist of known hosts. In a real setting, you might retrieve this
// list from config at ignite-time using tools like `AdHoc::config()`.
const WHITELIST: [Host<'static>; 3] = [
    Host::new(uri!("rocket.rs")),
    Host::new(uri!("rocket.rs:443")),
    Host::new(uri!("guide.rocket.rs:443")),
];

// A request with a host of "rocket.rs". Note the case-insensitivity.
request.set_host(Host::from(uri!("ROCKET.rs")));
let prefix = request.host().and_then(|h| h.to_absolute("https", &WHITELIST));

// `rocket.rs` is in the whitelist, so we'll get back a `Some`.
assert!(prefix.is_some());
if let Some(prefix) = prefix {
    // We can use this prefix to safely construct URIs.
    let uri = uri!(prefix, token("some-secret-token"));
    assert_eq!(uri, "https://ROCKET.rs/token?secret=some-secret-token");
}

// A request with a host of "attacker-controlled.com".
request.set_host(Host::from(uri!("attacker-controlled.com")));
let prefix = request.host().and_then(|h| h.to_absolute("https", &WHITELIST));

// `attacker-controlled.come` is _not_ on the whitelist.
assert!(prefix.is_none());
assert!(request.host().is_some());
source

pub fn set_host(&mut self, host: Host<'r>)

Sets the host of self to host.

Example

Set the host to rocket.rs:443.

use rocket::http::uri::Host;

assert_eq!(request.host(), None);

request.set_host(Host::from(uri!("rocket.rs:443")));
let host = request.host().unwrap();
assert_eq!(host.domain(), "rocket.rs");
assert_eq!(host.port(), Some(443));
source

pub fn remote(&self) -> Option<SocketAddr>

Returns the raw address of the remote connection that initiated this request if the address is known. If the address is not known, None is returned.

Because it is common for proxies to forward connections for clients, the remote address may contain information about the proxy instead of the client. For this reason, proxies typically set a “X-Real-IP” header ip_header with the client’s true IP. To extract this IP from the request, use the real_ip() or client_ip() methods.

Example
use std::net::{SocketAddrV4, Ipv4Addr};

assert_eq!(request.remote(), None);

let localhost = SocketAddrV4::new(Ipv4Addr::LOCALHOST, 8000).into();
request.set_remote(localhost);
assert_eq!(request.remote(), Some(localhost));
source

pub fn set_remote(&mut self, address: SocketAddr)

Sets the remote address of self to address.

Example

Set the remote address to be 127.0.0.1:8000:

use std::net::{SocketAddrV4, Ipv4Addr};

assert_eq!(request.remote(), None);

let localhost = SocketAddrV4::new(Ipv4Addr::LOCALHOST, 8000).into();
request.set_remote(localhost);
assert_eq!(request.remote(), Some(localhost));
source

pub fn real_ip(&self) -> Option<IpAddr>

Returns the IP address of the configured ip_header of the request if such a header is configured, exists and contains a valid IP address.

Example
use std::net::Ipv4Addr;
use rocket::http::Header;

assert_eq!(req.real_ip(), None);

// `ip_header` defaults to `X-Real-IP`.
let req = req.header(Header::new("X-Real-IP", "127.0.0.1"));
assert_eq!(req.real_ip(), Some(Ipv4Addr::LOCALHOST.into()));
source

pub fn client_ip(&self) -> Option<IpAddr>

Attempts to return the client’s IP address by first inspecting the ip_header and then using the remote connection’s IP address. Note that the built-in IpAddr request guard can be used to retrieve the same information in a handler:

use std::net::IpAddr;

#[get("/")]
fn get_ip(client_ip: IpAddr) { /* ... */ }

#[get("/")]
fn try_get_ip(client_ip: Option<IpAddr>) { /* ... */ }

If the ip_header exists and contains a valid IP address, that address is returned. Otherwise, if the address of the remote connection is known, that address is returned. Otherwise, None is returned.

Example

// starting without an "X-Real-IP" header or remote address
assert!(request.client_ip().is_none());

// add a remote address; this is done by Rocket automatically
request.set_remote("127.0.0.1:8000".parse().unwrap());
assert_eq!(request.client_ip(), Some("127.0.0.1".parse().unwrap()));

// now with an X-Real-IP header, the default value for `ip_header`.
request.add_header(Header::new("X-Real-IP", "8.8.8.8"));
assert_eq!(request.client_ip(), Some("8.8.8.8".parse().unwrap()));
source

pub fn cookies(&self) -> &CookieJar<'r>

Returns a wrapped borrow to the cookies in self.

CookieJar implements internal mutability, so this method allows you to get and add/remove cookies in self.

Example

Add a new cookie to a request’s cookies:

use rocket::http::Cookie;

req.cookies().add(Cookie::new("key", "val"));
req.cookies().add(Cookie::new("ans", format!("life: {}", 38 + 4)));

assert_eq!(req.cookies().get_pending("key").unwrap().value(), "val");
assert_eq!(req.cookies().get_pending("ans").unwrap().value(), "life: 42");
source

pub fn headers(&self) -> &HeaderMap<'r>

Returns a HeaderMap of all of the headers in self.

Example
use rocket::http::{Accept, ContentType};

assert!(get("/").headers().is_empty());

let req = get("/").header(Accept::HTML).header(ContentType::HTML);
assert_eq!(req.headers().len(), 2);
source

pub fn add_header<'h: 'r, H: Into<Header<'h>>>(&mut self, header: H)

Add header to self’s headers. The type of header can be any type that implements the Into<Header> trait. This includes common types such as ContentType and Accept.

Example
use rocket::http::ContentType;

assert!(request.headers().is_empty());

request.add_header(ContentType::HTML);
assert!(request.headers().contains("Content-Type"));
assert_eq!(request.headers().len(), 1);
source

pub fn replace_header<'h: 'r, H: Into<Header<'h>>>(&mut self, header: H)

Replaces the value of the header with name header.name with header.value. If no such header exists, header is added as a header to self.

Example
use rocket::http::ContentType;

assert!(request.headers().is_empty());

request.add_header(ContentType::Any);
assert_eq!(request.headers().get_one("Content-Type"), Some("*/*"));
assert_eq!(request.content_type(), Some(&ContentType::Any));

request.replace_header(ContentType::PNG);
assert_eq!(request.headers().get_one("Content-Type"), Some("image/png"));
assert_eq!(request.content_type(), Some(&ContentType::PNG));
source

pub fn content_type(&self) -> Option<&ContentType>

Returns the Content-Type header of self. If the header is not present, returns None.

Example
use rocket::http::ContentType;

assert_eq!(get("/").content_type(), None);

let req = get("/").header(ContentType::JSON);
assert_eq!(req.content_type(), Some(&ContentType::JSON));
source

pub fn accept(&self) -> Option<&Accept>

Returns the Accept header of self. If the header is not present, returns None.

Example
use rocket::http::Accept;

assert_eq!(get("/").accept(), None);
assert_eq!(get("/").header(Accept::JSON).accept(), Some(&Accept::JSON));
source

pub fn format(&self) -> Option<&MediaType>

Returns the media type “format” of the request.

The “format” of a request is either the Content-Type, if the request methods indicates support for a payload, or the preferred media type in the Accept header otherwise. If the method indicates no payload and no Accept header is specified, a media type of Any is returned.

The media type returned from this method is used to match against the format route attribute.

Example
use rocket::http::{Accept, ContentType, MediaType};

// Non-payload-bearing: format is accept header.
let req = get("/").header(Accept::HTML);
assert_eq!(req.format(), Some(&MediaType::HTML));

let req = get("/").header(ContentType::JSON).header(Accept::HTML);
assert_eq!(req.format(), Some(&MediaType::HTML));

// Payload: format is content-type header.
let req = post("/").header(ContentType::HTML);
assert_eq!(req.format(), Some(&MediaType::HTML));

let req = post("/").header(ContentType::JSON).header(Accept::HTML);
assert_eq!(req.format(), Some(&MediaType::JSON));

// Non-payload-bearing method and no accept header: `Any`.
assert_eq!(get("/").format(), Some(&MediaType::Any));
source

pub fn rocket(&self) -> &'r Rocket<Orbit>

Returns the Rocket instance that is handling this request.

Example
// Retrieve the application config via `Rocket::config()`.
let config = request.rocket().config();

// Retrieve managed state via `Rocket::state()`.
let state = request.rocket().state::<Pool>();

// Get a list of all of the registered routes and catchers.
let routes = request.rocket().routes();
let catchers = request.rocket().catchers();
source

pub fn limits(&self) -> &'r Limits

Returns the configured application data limits.

This is convenience function equivalent to:

&request.rocket().config().limits
Example
use rocket::data::ToByteUnit;

// This is the default `form` limit.
assert_eq!(request.limits().get("form"), Some(32.kibibytes()));

// Retrieve the limit for files with extension `.pdf`; etails to 1MiB.
assert_eq!(request.limits().get("file/pdf"), Some(1.mebibytes()));
source

pub fn route(&self) -> Option<&'r Route>

Get the presently matched route, if any.

This method returns Some any time a handler or its guards are being invoked. This method returns None before routing has commenced; this includes during request fairing callbacks.

Example
let route = request.route();
source

pub fn guard<'z, 'a, T>(&'a self) -> BoxFuture<'z, Outcome<T, T::Error>>where T: FromRequest<'a> + 'z, 'a: 'z, 'r: 'z,

Invokes the request guard implementation for T, returning its outcome.

Example

Assuming a User request guard exists, invoke it:

let outcome = request.guard::<User>().await;
source

pub fn local_cache<T, F>(&self, f: F) -> &Twhere F: FnOnce() -> T, T: Send + Sync + 'static,

Retrieves the cached value for type T from the request-local cached state of self. If no such value has previously been cached for this request, f is called to produce the value which is subsequently returned.

Different values of the same type cannot be cached without using a proxy, wrapper type. To avoid the need to write these manually, or for libraries wishing to store values of public types, use the local_cache! or local_cache_once! macros to generate a locally anonymous wrapper type, store, and retrieve the wrapped value from request-local cache.

Example
// The first store into local cache for a given type wins.
let value = request.local_cache(|| "hello");
assert_eq!(*request.local_cache(|| "hello"), "hello");

// The following return the cached, previously stored value for the type.
assert_eq!(*request.local_cache(|| "goodbye"), "hello");
source

pub async fn local_cache_async<'a, T, F>(&'a self, fut: F) -> &'a Twhere F: Future<Output = T>, T: Send + Sync + 'static,

Retrieves the cached value for type T from the request-local cached state of self. If no such value has previously been cached for this request, fut is awaited to produce the value which is subsequently returned.

Example
async fn current_user<'r>(request: &Request<'r>) -> User {
    // validate request for a given user, load from database, etc
}

let current_user = request.local_cache_async(async {
    current_user(&request).await
}).await;
source

pub fn param<'a, T>(&'a self, n: usize) -> Option<Result<T, T::Error>>where T: FromParam<'a>,

Retrieves and parses into T the 0-indexed nth non-empty segment from the routed request, that is, the nth segment after the mount point. If the request has not been routed, then this is simply the nth non-empty request URI segment.

Returns None if n is greater than the number of non-empty segments. Returns Some(Err(T::Error)) if the parameter type T failed to be parsed from the nth dynamic parameter.

This method exists only to be used by manual routing. To retrieve parameters from a request, use Rocket’s code generation facilities.

Example
use rocket::error::Empty;

assert_eq!(get("/a/b/c").param(0), Some(Ok("a")));
assert_eq!(get("/a/b/c").param(1), Some(Ok("b")));
assert_eq!(get("/a/b/c").param(2), Some(Ok("c")));
assert_eq!(get("/a/b/c").param::<&str>(3), None);

assert_eq!(get("/1/b/3").param(0), Some(Ok(1)));
assert!(get("/1/b/3").param::<usize>(1).unwrap().is_err());
assert_eq!(get("/1/b/3").param(2), Some(Ok(3)));

assert_eq!(get("/").param::<&str>(0), Some(Err(Empty)));
source

pub fn segments<'a, T>(&'a self, n: RangeFrom<usize>) -> Result<T, T::Error>where T: FromSegments<'a>,

Retrieves and parses into T all of the path segments in the request URI beginning and including the 0-indexed nth non-empty segment after the mount point.,that is, the nth segment after the mount point. If the request has not been routed, then this is simply the nth non-empty request URI segment.

T must implement FromSegments, which is used to parse the segments. If there are no non-empty segments, the Segments iterator will be empty.

This method exists only to be used by manual routing. To retrieve segments from a request, use Rocket’s code generation facilities.

Example
use std::path::PathBuf;

assert_eq!(get("/").segments(0..), Ok(PathBuf::new()));
assert_eq!(get("/").segments(2..), Ok(PathBuf::new()));

// Empty segments are skipped.
assert_eq!(get("///").segments(2..), Ok(PathBuf::new()));
assert_eq!(get("/a/b/c").segments(0..), Ok(PathBuf::from("a/b/c")));
assert_eq!(get("/a/b/c").segments(1..), Ok(PathBuf::from("b/c")));
assert_eq!(get("/a/b/c").segments(2..), Ok(PathBuf::from("c")));
assert_eq!(get("/a/b/c").segments(3..), Ok(PathBuf::new()));
assert_eq!(get("/a/b/c").segments(4..), Ok(PathBuf::new()));
source

pub fn query_value<'a, T>(&'a self, name: &str) -> Option<Result<'a, T>>where T: FromForm<'a>,

Retrieves and parses into T the query value with field name name. T must implement FromForm, which is used to parse the query’s value. Key matching is performed case-sensitively.

Warning

This method exists only to be used by manual routing and should never be used in a regular Rocket application. It is much more expensive to use this method than to retrieve query parameters via Rocket’s codegen. To retrieve query values from a request, always prefer to use Rocket’s code generation facilities.

Error

If a query segment with name name isn’t present, returns None. If parsing the value fails, returns Some(Err(_)).

Example
use rocket::form::FromForm;

#[derive(Debug, PartialEq, FromForm)]
struct Dog<'r> {
    name: &'r str,
    age: usize
}

let req = get("/?a=apple&z=zebra&a=aardvark");
assert_eq!(req.query_value::<&str>("a").unwrap(), Ok("apple"));
assert_eq!(req.query_value::<&str>("z").unwrap(), Ok("zebra"));
assert_eq!(req.query_value::<&str>("b"), None);

let a_seq = req.query_value::<Vec<&str>>("a");
assert_eq!(a_seq.unwrap().unwrap(), ["apple", "aardvark"]);

let req = get("/?dog.name=Max+Fido&dog.age=3");
let dog = req.query_value::<Dog>("dog");
assert_eq!(dog.unwrap().unwrap(), Dog { name: "Max Fido", age: 3 });
