High-performance Rust HTTP client. Use reqwest with KnoxProxy for blazing-fast concurrent proxy requests with memory safety.
Add to Cargo.toml.
[dependencies]
reqwest = { version = "0.12", features = ["json"] }
tokio = { version = "1", features = ["full"] }Build client with proxy.
let proxy = reqwest::Proxy::all("http://USER:PASS@gw.knoxproxy.com:7000")?;
let client = reqwest::Client::builder().proxy(proxy).build()?;Send through proxy.
let body = client.get("https://httpbin.org/ip").send().await?.text().await?;
println!("{body}");Add country to username.
reqwest::Proxy::all("http://USER-country-us:PASS@gw.knoxproxy.com:7000")?Use tokio tasks.
let handles: Vec<_> = urls.iter().map(|url| {
let c = client.clone();
tokio::spawn(async move { c.get(url).send().await })
}).collect();
for h in handles { h.await??; }Verify exit IP.
//! KnoxProxy + Rust reqwest -- concurrent proxy requests.
use reqwest;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let proxy = reqwest::Proxy::all("http://USER:PASS@gw.knoxproxy.com:7000")?;
let client = reqwest::Client::builder()
.proxy(proxy)
.timeout(std::time::Duration::from_secs(30))
.build()?;
let body = client
.get("https://httpbin.org/ip")
.send()
.await?
.text()
.await?;
println!("Exit IP: {body}");
Ok(())
}reqwest connection pool may reuse connections. Create a new Client per rotation cycle, or use -session-{id} for explicit control.
| Problem | Fix |
|---|---|
| reqwest::Error: error sending request | Verify host, port, and network. |
| StatusCode 407 | Check credentials in proxy URL. |
USER-country-de-city-berlin-session-profile07Order matters -- geo flags before the session flag. The session name is free text; use the profile ID so the mapping is self-documenting. Password stays as issued; no flags belong there. HTTP on :7000, SOCKS5 on :7001, same credentials.
Rust has lower overhead and better memory efficiency. For CPU-bound parsing of large datasets, Rust is faster. For I/O-bound proxy requests, the bottleneck is network latency, so the difference is small.
Yes, enable the socks feature: reqwest = { features = ["socks"] }. Use Proxy::all("socks5://...").
Yes, but reqwest is the recommended high-level client. For raw HTTP/2 or custom transports, use hyper with a proxy connector.
Use the reqwest-retry middleware or implement a retry loop with tokio::time::sleep for exponential backoff.
