TCP Socket Connect through HTTP Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to connect through an HTTP proxy server. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

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

    const socket = try chilkat.Socket.init();
    defer socket.deinit();

    // 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.setHttpProxyHostname("www.my-http-proxy.com");
    socket.setHttpProxyPort(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.
    const hostname = "192.168.1.108";
    const ssl = false;
    const max_wait_millisec = 20000;
    socket.connect(hostname, 5555, ssl, max_wait_millisec) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

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

    // The ficticious server (in this example) is going to send a "Hello World!"
    // message.  Read it:
    const received_msg = socket.receiveString(alloc) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

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

    std.debug.print("{s}\n", .{received_msg});
