What is it?

reqwest is an HTTP client library for Rust. It provides both async and blocking clients, so it can be used in Tokio-based async programs or in simple synchronous code. Request bodies can be plain bytes, JSON, urlencoded forms or multipart uploads, and responses can be decoded into typed values.

The library includes a customizable redirect policy, HTTP proxy support, and a cookie store. HTTPS uses rustls by default; the native-tls feature switches to the operating system's TLS stack on Windows and macOS, or to OpenSSL on Linux, and a vendored OpenSSL option is also available. The crate can also be compiled to WASM.

Key features

  • 01Async and blocking clients
  • 02JSON, urlencoded and multipart request bodies
  • 03Customizable redirect policy
  • 04HTTP proxy support
  • 05HTTPS via rustls or system-native TLS
  • 06Cookie store and WASM support

Use cases

  • Calling REST or JSON APIs from a Rust service or CLI
  • Uploading files with multipart form requests
  • Making synchronous HTTP requests in a small tool without an async runtime

Quick start

  1. 1

    Add reqwest with the json feature and tokio to Cargo.toml

    reqwest = { version = "0.13", features = ["json"] }
  2. 2

    Add tokio with the full feature set to Cargo.toml

    tokio = { version = "1", features = ["full"] }
  3. 3

    Write the example code from the README into src/main.rs and run it

Things to know

  • Native TLS on Linux requires OpenSSL to be installed or the vendored feature to be enabled.
