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 = "0.31.0"

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 = "0.31.0", 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(())
}

Modify Client settings

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.

About

The predecessor of rquest is reqwest. rquest is a specialized adaptation based on the reqwest project, supporting BoringSSL and related HTTP/2 fingerprints in requests.

It also optimizes commonly used APIs and enhances compatibility with connection pools, making it easier to switch proxies, IP addresses, and interfaces. You can directly migrate from a project using reqwest to rquest.

Due to limited time for maintaining the synchronous APIs, only asynchronous APIs are supported. I may have to give up maintenance; if possible, please consider sponsoring me.
