用法

将此添加到您的 Cargo.toml

[package]
name = "rust-hello-world"
version = "0.1.0"
edition = "2021"

[dependencies]
anyhow = "1.0.75"
http = "0.2.9"
land-sdk = "0.1.4"
# wit-component > 0.14.5 is not compatible with wit-bindgen 0.12.0

示例

use land_sdk::http::{Body, Error, Request, Response};
use land_sdk::http_main;

#[http_main]
pub fn handle_request(req: Request) -> Result<Response, Error> {
    let url = req.uri().clone();
    let method = req.method().to_string().to_uppercase();
    Ok(http::Response::builder()
        .status(200)
        .header("X-Request-Url", url.to_string())
        .header("X-Request-Method", method)
        .body(Body::from("Hello Runtime.land!!"))
        .unwrap())
}

lib.rs:

Rust SDK for Runtime.land.

此SDK用于开发Runtime.land函数。它通过Runtime.land上的land_sdk::http模块提供了一套处理http请求和响应的方法。

Hello World

use land_sdk::http::{Body, Error, Request, Response};
use land_sdk::http_main;

#[http_main]
pub fn handle_request(req: Request) -> Result<Response, Error> {
    // read uri and method from request
    let url = req.uri().clone();
    let method = req.method().to_string().to_uppercase();

    // build response
    Ok(http::Response::builder()
        .status(200)
        .header("X-Request-Url", url.to_string())
        .header("X-Request-Method", method)
        .body(Body::from("Hello Runtime.land!!"))
        .unwrap())
}
