Function send

pub async fn send<I, O>(request: I) -> Result<O, SendError>
where
    I: TryIntoOutgoingRequest,
    I::Error: Into<Box<dyn Error + Send + Sync>> + 'static,
    O: TryFromIncomingResponse,
    O::Error: Into<Box<dyn Error + Send + Sync>> + 'static,

Send an outgoing request

Examples

Get the example.com home page:

use spin_sdk::http::{Request, Response};

let request = Request::get("example.com").build();
let response: Response = spin_sdk::http::send(request).await?;
println!("{}", response.body().len());

Use the http crate Request type to send a data transfer value:

use hyperium::Request;

#[derive(serde::Serialize)]
struct User {
    name: String,
}

impl spin_sdk::http::conversions::TryIntoBody for User {
    type Error = serde_json::Error;

    fn try_into_body(self) -> Result<Vec<u8>, Self::Error> {
        serde_json::to_vec(&self)
    }
}

let user = User {
    name: "Alice".to_owned(),
};

let request = hyperium::Request::builder()
    .method("POST")
    .uri("https://example.com/users")
    .header("content-type", "application/json")
    .body(user)?;

let response: hyperium::Response<()> = spin_sdk::http::send(request).await?;

println!("{}", response.status().is_success());
