Struct rocket::local::LocalRequest [−] [src]

pub struct LocalRequest<'c> { /* fields omitted */ }

A structure representing a local request as created by Client.

Usage

A LocalRequest value is constructed via method constructors on Client. Headers can be added via the header builder method and the add_header method. Cookies can be added via the cookie builder method. The remote IP address can be set via the remote builder method. The body of the request can be set via the body builder method or set_body method.

Example

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

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

let client = Client::new(rocket::ignite()).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 }"#);

Dispatching

A LocalRequest can be dispatched in one of three ways:

  1. dispatch

    This method should always be preferred. The LocalRequest is consumed and a response is returned.

  2. cloned_dispatch

    This method should be used when one LocalRequest will be dispatched many times. This method clones the request and dispatches the clone, so the request is not consumed and can be reused.

  3. mut_dispatch

    This method should only be used when either it is known that the application will not modify the request, or it is desired to see modifications to the request. No cloning occurs, and the request is not consumed.

Methods

impl<'c> LocalRequest<'c>
[src]

Retrieves the inner Request as seen by Rocket.

Example

use rocket::local::Client;

let client = Client::new(rocket::ignite()).expect("valid rocket");
let req = client.get("/");
let inner_req = req.inner();

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::Client;
use rocket::http::ContentType;

let client = Client::new(rocket::ignite()).unwrap();
let req = client.get("/").header(ContentType::JSON);

Adds a header to this request without consuming self.

Examples

Add the Content-Type header:

use rocket::local::Client;
use rocket::http::ContentType;

let client = Client::new(rocket::ignite()).unwrap();
let mut req = client.get("/");
req.add_header(ContentType::JSON);

Set the remote address of this request.

Examples

Set the remote address to "8.8.8.8:80":

use rocket::local::Client;

let client = Client::new(rocket::ignite()).unwrap();
let address = "8.8.8.8:80".parse().unwrap();
let req = client.get("/").remote(address);

Add a cookie to this request.

Examples

Add user_id cookie:

use rocket::local::Client;
use rocket::http::Cookie;

let client = Client::new(rocket::ignite()).unwrap();
let req = client.get("/")
    .cookie(Cookie::new("username", "sb"))
    .cookie(Cookie::new("user_id", "12"));

Set the body (data) of the request.

Examples

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

use rocket::local::Client;
use rocket::http::ContentType;

let client = Client::new(rocket::ignite()).unwrap();
let req = client.post("/")
    .header(ContentType::JSON)
    .body(r#"{ "key": "value", "array": [1, 2, 3], }"#);

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::Client;
use rocket::http::ContentType;

let client = Client::new(rocket::ignite()).unwrap();
let mut req = client.post("/").header(ContentType::JSON);
req.set_body(r#"{ "key": "value", "array": [1, 2, 3], }"#);

Dispatches the request, returning the response.

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

Example

use rocket::local::Client;

let client = Client::new(rocket::ignite()).unwrap();
let response = client.get("/").dispatch();

Dispatches the request, returning the response.

This method does not consume self. Instead, it clones self and dispatches the clone. As such, self can be reused.

Example

use rocket::local::Client;

let client = Client::new(rocket::ignite()).unwrap();

let req = client.get("/");
let response_a = req.cloned_dispatch();
let response_b = req.cloned_dispatch();

Dispatches the request, returning the response.

This method does not consume or clone self. Any changes to the request that occur during handling will be visible after this method is called. For instance, body data is always consumed after a request is dispatched. As such, only the first call to mut_dispatch for a given LocalRequest will contains the original body data.

This method should only be used when either it is known that the application will not modify the request, or it is desired to see modifications to the request. Prefer to use dispatch or cloned_dispatch instead

Example

use rocket::local::Client;

let client = Client::new(rocket::ignite()).unwrap();

let mut req = client.get("/");
let response_a = req.mut_dispatch();
let response_b = req.mut_dispatch();
