Usage

This asynchronous example uses Tokio and enables some optional features, so your Cargo.toml could look like this:

HTTP

[dependencies]
tokio = { version = "1", features = ["full"] }
rquest = "0.27"

use rquest::tls::Impersonate;

#[tokio::main]
async fn main() -> Result<(), rquest::Error> {
    // Build a client to mimic Chrome131
    let client = rquest::Client::builder()
        .impersonate(Impersonate::Chrome131)
        .build()?;

    // Use the API you're already familiar with
    let resp = client.get("https://tls.peet.ws/api/all").send().await?;
    println!("{}", resp.text().await?);

    Ok(())
}

WebSocket

[dependencies]
tokio = { version = "1", features = ["full"] }
rquest = { version = "0.27", features = ["websocket"] }

use futures_util::{SinkExt, StreamExt, TryStreamExt};
use rquest::{tls::Impersonate, Client, Message};

#[tokio::main]
async fn main() -> Result<(), rquest::Error> {
    // Build a client to mimic Chrome131
    let client = Client::builder()
        .impersonate(Impersonate::Chrome131)
        .build()?;

    // Use the API you're already familiar with
    let websocket = client
        .websocket("wss://echo.websocket.org")
        .send()
        .await?
        .into_websocket()
        .await?;

    let (mut tx, mut rx) = websocket.split();

    tokio::spawn(async move {
        for i in 1..11 {
            tx.send(Message::Text(format!("Hello, World! #{i}")))
                .await
                .unwrap();
        }
    });

    while let Some(message) = rx.try_next().await? {
        match message {
            Message::Text(text) => println!("received: {text}"),
            _ => {}
        }
    }

    Ok(())
}

Preconfigured TLS/HTTP2

Requirement

Install the environment required to build BoringSSL

Do not compile with crates that depend on OpenSSL; their prefixing symbols are the same and may cause linking failures.

If both OpenSSL and BoringSSL are used as dependencies simultaneously, even if the compilation succeeds, strange issues may still arise.

Building

sudo apt-get install build-essential cmake perl pkg-config libclang-dev musl-tools -y

cargo build --release

You can also use this GitHub Actions workflow to compile your project on Linux, Windows, and macOS.
