Whats the equivalent of pythons request package for rust?

Feb 3, 2024 ยท 3 min read

Rust is a systems programming language focused on performance, reliability, and efficiency. As more developers adopt Rust for building applications, there is a need for robust HTTP client libraries like Python's ubiquitous requests package.

The most popular HTTP client library for Rust is reqwest. In many ways, reqwest provides a similar developer experience to requests with some key differences we'll explore in this article.

Getting Started with reqwest

To start using reqwest, first add it as a dependency in your Cargo.toml file:

reqwest = "0.11"

Then import the crate in your Rust code:

use reqwest;

Making a Basic GET Request

Here is an example of making a simple GET request with reqwest:

let resp = reqwest::get("https://www.rust-lang.org")

println!("Response: {}", resp);

This makes a GET request to the Rust language homepage, awaits the response, reads the response body as text, and prints it out.

The .await? syntax is necessary since all reqwest functions use Rust's async/await model rather than synchronous requests and responses.

POST Requests and Request Options

Here is an example of a POST request with some request options like headers:

let client = reqwest::Client::new();
let resp = client.post("https://httpbin.org/post")
    .header("User-Agent", "My Rust App")
        "lang" => "Rust",
        "package" => "reqwest"

This demonstrates creating a Client instance, setting headers, sending JSON data, making the request, and handling the response.

Handling Errors

reqwest uses Rust's Result enum for error handling. Typically you would handle errors like:

let resp = reqwest::get("https://mysite.com").await;

match resp {
    Ok(resp) => println!("Success!"),
    Err(err) => println!("Error: {}", err),

This matches on the Result and prints either the successful response or the error.

Timeouts, Redirects, and Other Configuration

The Client struct in reqwest provides various configuration options like timeouts, redirect policies, proxy settings, and more:

let client = reqwest::Client::builder()

So reqwest provides a lot of control over the HTTP client behavior.


In summary, reqwest brings an ergonomic and full-featured HTTP client library to Rust. It handles async requests cleanly using Rust's futures and tokio runtime. With syntax and capabilities similar to Python's well-known requests module, reqwest makes it easy to start making HTTP requests in your Rust applications.

To learn more, check out the official reqwest documentation. The examples provide more detail on advanced usage like multipart file uploads, websockets, and custom response handling. Rust's strong typing also ensures your HTTP logic stays safe and correct.

So give reqwest a try on your next Rust project that needs to talk HTTP!
