TCP Socket Connect through HTTP Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to connect through an HTTP proxy server. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let socket = chilkat::Socket::new();

// To connect through an HTTP proxy, set the HttpProxyHostname
// and HttpProxyPort properties to the hostname (or IP address)
// and port of the HTTP proxy.  Typical port numbers used by
// HTTP proxy servers are 3128 and 8080.
socket.set_http_proxy_hostname("www.my-http-proxy.com");
socket.set_http_proxy_port(3128);

// Important:  Your HTTP proxy server must allow non-HTTP
// traffic to pass.  Otherwise this does not work.

// Connect (via the HTTP proxy) to port 5555 of 192.168.1.108.
// hostname may be a domain name or IP address.
let hostname = "192.168.1.108".to_string();
let ssl = false;
let max_wait_millisec = 20000;
if socket.connect(&hostname, 5555, ssl, max_wait_millisec).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// Set maximum timeouts for reading an writing (in millisec)
socket.set_max_read_idle_ms(10000);
socket.set_max_send_idle_ms(10000);

// The ficticious server (in this example) is going to send a "Hello World!" 
// message.  Read it:
let Ok(received_msg) = socket.receive_string() else {
    println!("{}", socket.last_error_text());
    return;
};

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
let _ = socket.close(20000).is_ok();

println!("{}", received_msg);
