Struct reqwest::RequestBuilder[−][src]

pub struct RequestBuilder { /* fields omitted */ }
Expand description

A builder to construct the properties of a Request.

Implementations

Modify the query string of the URL.

Modifies the URL of this request, adding the parameters provided. This method appends and does not overwrite. This means that it can be called multiple times and that existing query parameters are not overwritten if the same key is used. The key will simply show up twice in the query string. Calling .query([("foo", "a"), ("foo", "b")]) gives "foo=a&foo=b".

Note

This method does not support serializing a single key-value pair. Instead of using .query(("key", "val")), use a sequence, such as .query(&[("key", "val")]). It’s also possible to serialize structs and maps into a key-value pair.

Errors

This method will fail if the object you provide cannot be serialized into a query string.

Send a form body.

This is supported on crate feature json only.

Set the request json

Enable HTTP bearer authentication.

Set the request body.

This is supported on crate feature multipart only.

TODO

Add a Header to this Request.

Add a set of Headers to the existing ones on this Request.

The headers will be merged in to any already set.

Disable CORS on fetching the request.

Build a Request, which can be inspected, modified and executed with Client::execute().

Constructs the Request and sends it to the target URL, returning a future Response.

Errors

This method fails if there was an error while sending request.

Example

let response = reqwest::Client::new()
    .get("https://hyper.rs")
    .send()
    .await?;

Attempt to clone the RequestBuilder.

None is returned if the RequestBuilder can not be cloned. This method currently always returns Some, but that may change in the future.

Examples

let client = reqwest::Client::new();
let builder = client.post("http://httpbin.org/post")
    .body("from a &str!");
let clone = builder.try_clone();
assert!(clone.is_some());
