TCP/IP Socket Connect to Remote Host:Port

See more Socket/SSL/TLS Examples

Demonstrates how to create a TCP/IP socket, connect to a remote host:port, and receive a "Hello World!" message. Rust

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

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

// Connect to port 5555 of localhost.
// The string "localhost" is for testing on a single computer.
// It would typically be replaced with an IP hostname, such
// as "www.chilkatsoft.com".
let ssl = false;
let max_wait_millisec = 20000;
if socket.connect("localhost", 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);

// Pretend, for the sake of the example, that the
// ficticious server is going to send a "Hello World!" 
// after accepting the connection.  
// Note: Technically, the ReceiveString may not receive the
// complete string, although it's highly probable given the short
// length of the "Hello World!" message. 
// See this Chilkat blog post for more information:
// <a href="http://www.cknotes.com/?p=302">http://www.cknotes.com/?p=302</a>
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);
