reqwest exposes the “pool_max_idle_per_host” option of hyper’s client builder. This option used to be called “max_idle_per_host” in the hyper crate, but it has recently been renamed [1]. This patch renames the reqwest representation of this option to make it consistent with its name in the hyper crate again. [1] https://github.com/hyperium/hyper/pull/2142
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
Example
This asynchronous example uses Tokio and enables some
optional features, so your Cargo.toml could look like this:
[dependencies]
reqwest = { version = "0.10", features = ["json"] }
tokio = { version = "0.2", features = ["full"] }
And then the code:
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:
[dependencies]
reqwest = { version = "0.10", features = ["blocking", "json"] }
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 1.0.1, 1.0.2, 1.1.0, or 1.1.1 with headers (see https://github.com/sfackler/rust-openssl)
On Windows and macOS:
- Nothing.
Reqwest uses rust-native-tls, which will use the operating system TLS framework if available, meaning Windows and macOS. On Linux, it will use OpenSSL 1.1.
