rquest

🚀 Help me work seamlessly with open source sharing by sponsoring me on GitHub

An ergonomic all-in-one HTTP client for browser emulation with TLS, JA3/JA4, and HTTP/2 fingerprints.

Features

• Plain bodies, JSON, urlencoded, multipart
• Cookie Store
• Header Order
• Redirect Policy
• Rotating Proxies
• WebSocket Upgrade
• HTTPS via BoringSSL
• Emulation Fingerprint

Example

This asynchronous example utilizes Tokio with optional features enabled, requiring the following configuration in Cargo.toml:

[dependencies]
tokio = { version = "1", features = ["full"] }
rquest = "4"
rquest-util = "1"

And then the code:

use rquest::Client;
use rquest_util::Emulation;

#[tokio::main]
async fn main() -> Result<(), rquest::Error> {
    // Build a client
    let client = Client::builder()
        .emulation(Emulation::Firefox136)
        .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(())
}

Emulation

• HTTP/2 over TLS

  JA3/JA4/Akamai fingerprints cannot accurately simulate browser fingerprints due to the sophistication of TLS encryption and the popularity of HTTP/2. rquest does not plan to support parsing these fingerprint strings for simulation. Users are encouraged to customize the configuration according to their own needs.

• Emulation Device

  Most browser device models share the same TLS and HTTP/2 configuration, differing only in the User-Agent. The browser device emulation template is managed by rquest-util.

Building

Avoid compiling with packages that depend on openssl-sys, as it shares the same prefix symbol with boring-sys, potentially leading to link failures and other issues. Even if compilation succeeds, using both openssl-sys and boring-sys together can result in memory segmentation faults. Until the upstream Boring resolves these linking conflicts, using rustls is the best workaround.

Install the dependencies required to build BoringSSL

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

cargo build --release

This GitHub Actions workflow can be used to compile the project on Linux, Windows, and macOS.
