# reqwest-impersonate

A fork of reqwest used to impersonate the Chrome browser. Inspired by [curl-impersonate](https://github.com/lwthiker/curl-impersonate).

This crate was intended to be an experiment to learn more about TLS and HTTP2 fingerprinting. Some parts of reqwest may not have the code needed to work when used to copy Chrome.

It is currently missing HTTP/2 `PRIORITY` support. (PRs to [h2](https://github.com/hyperium/h2) are welcome)

**Notice:** This crate depends on patched dependencies. To use it, please add the following to your `Cargo.toml`.

```toml
[patch.crates-io]
hyper = { git = "https://github.com/4JX/hyper.git", branch = "v0.14.18-patched" }
h2 = { git = "https://github.com/4JX/h2.git", branch = "imp" }
```

These patches were made specifically for `reqwest-impersonate` to work, but I would appreciate if someone took the time to PR more "proper" versions to the parent projects.

## Example

`Cargo.toml`

```toml
reqwest-impersonate = { git = "https://github.com/4JX/reqwest-impersonate.git", default-features = false, features = [
    "chrome",
    "blocking",
] }
```

`main.rs`

```rs
use reqwest_impersonate::browser::ChromeVersion;

fn main() {
    // Build a client to mimic Chrome 104
    let client = reqwest_impersonate::blocking::Client::builder()
        .chrome_builder(ChromeVersion::V104)
        .build()
        .unwrap();

    // Use the API you're already familiar with
    match client.get("https://yoururl.com").send() {
        Ok(res) => {
            println!("{:?}", res.text().unwrap());
        }
        Err(err) => {
            dbg!(err);
        }
    };
}
```

## Example

This asynchronous example uses [Tokio](https://tokio.rs) and enables some
optional features, so your `Cargo.toml` could look like this:

```toml
[dependencies]
reqwest = { version = "0.11", features = ["json"] }
tokio = { version = "1", features = ["full"] }
```

And then the code:

```rust,no_run
use std::collections::HashMap;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let resp = reqwest::get("https://httpbin.org/ip")
        .await?
        .json::<HashMap<String, String>>()
        .await?;
    println!("{:#?}", resp);
    Ok(())
}
```

## Blocking Client

There is an optional "blocking" client API that can be enabled:

```toml
[dependencies]
reqwest = { version = "0.11", features = ["blocking", "json"] }
```

```rust,no_run
use std::collections::HashMap;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let resp = reqwest::blocking::get("https://httpbin.org/ip")?
        .json::<HashMap<String, String>>()?;
    println!("{:#?}", resp);
    Ok(())
}
```

## Requirements

On Linux:

- OpenSSL 1.0.1, 1.0.2, 1.1.0, or 1.1.1 with headers (see <https://github.com/sfackler/rust-openssl>)

On Windows and macOS:

- Nothing.

Reqwest uses [rust-native-tls](https://github.com/sfackler/rust-native-tls),
which will use the operating system TLS framework if available, meaning Windows
and macOS. On Linux, it will use OpenSSL 1.1.
