rust-使用rust开发的http客户端代码.zip

# reqwest An ergonomic, batteries-included HTTP Client for Rust. - Plain bodies, JSON, urlencoded, multipart - Customizable redirect policy - HTTP Proxies - HTTPS via system-native TLS (or optionally, rustls) - Cookie Store - WASM - [Changelog](CHANGELOG.md) ## Example This asynchronous example uses [Tokio](https://tokio.rs) and enables some optional features, so your `Cargo.toml` could look like this: ```toml [dependencies] reqwest = { version = "0.11", features = ["json"] } tokio = { version = "1", features = ["full"] } ``` And then the code: ```rust,no_run use std::collections::HashMap; #[tokio::main] async fn main() -> Result<(), Box<dyn std::error::Error>> { let resp = reqwest::get("https://httpbin.org/ip") .await? .json::<HashMap<String, String>>() .await?; println!("{resp:#?}"); Ok(()) } ``` ## Blocking Client There is an optional "blocking" client API that can be enabled: ```toml [dependencies] reqwest = { version = "0.11", features = ["blocking", "json"] } ``` ```rust,no_run use std::collections::HashMap; fn main() -> Result<(), Box<dyn std::error::Error>> { let resp = reqwest::blocking::get("https://httpbin.org/ip")? .json::<HashMap<String, String>>()?; println!("{resp:#?}"); Ok(()) } ``` ## Requirements On Linux: - OpenSSL with headers. See https://docs.rs/openssl for supported versions and more details. Alternatively you can enable the `native-tls-vendored` feature to compile a copy of OpenSSL.
