An ergonomic all-in-one HTTP client for browser emulation with TLS, JA3/JA4, and HTTP/2 fingerprints.
> Version migration: wreq 0.15.3 replaces wreq 5.3.0 under the new versioning
> policy. Cargo will not migrate existing 5.x requirements automatically, so
> update them to `wreq = "0.15"`. The 6.0.0-rc line is frozen. The next
> release will be the stable 0.16.0.
## Features
- Plain bodies, JSON, urlencoded, multipart
- Cookie Store
- Header Order
- Redirect Policy
- Rotating Proxies
- Certificate Store
- WebSocket Upgrade
- HTTPS via BoringSSL
- HTTP/2 over TLS Emulation
## Example
This asynchronous example utilizes [Tokio](https://tokio.rs) with optional features enabled, requiring the following configuration in `Cargo.toml`:
```toml
[dependencies]
tokio = { version = "1", features = ["full"] }
wreq = "0.15"
wreq-util = "0.1"
```
And then the code:
```rust,no_run
use wreq::Client;
use wreq_util::Emulation;
#[tokio::main]
async fn main() -> Result<(), wreq::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. wreq does not plan to support parsing these fingerprint strings for simulation. Users are encouraged to customize the configuration according to their own needs.
## 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](https://github.com/cloudflare/boring/issues/197) 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](https://github.com/google/boringssl/blob/master/BUILDING.md#build-prerequisites)
```shell
sudo apt-get install build-essential cmake perl pkg-config libclang-dev musl-tools -y
cargo build --release
```
