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 = "0.21"

use std::error::Error;
use rquest::tls::Impersonate;

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    // Build a client to mimic Chrome128
    let client = rquest::Client::builder()
        .impersonate(Impersonate::Chrome128)
        .enable_ech_grease()
        .permute_extensions()
        .cookie_store(true)
        .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 = "0.21", features = ["websocket"] }

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

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let websocket = rquest::websocket("wss://echo.websocket.org").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

rquest = "0.21"

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.
