Zig Requires Chilkat v11.0.0+

Example: Http.HttpSb method

Shows how to use the HttpSb method to send an HTTP POST request with a StringBuilder as the request body. The example sends the following request:

POST /echo_request_body.asp HTTP/1.1
Host: chilkatsoft.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

    // This URL echoes the contents of the request body, letting us view it.
    const url = "https://chilkatsoft.com/echo_request_body.asp";

    // Send a POST with the contents of the StringBuilder in the HTTP request body.
    const resp = try chilkat.HttpResponse.init();
    defer resp.deinit();
    http.httpSb("POST", url, sb, "utf-8", "application/json", resp) catch {

    std.debug.print("Response Status Code: {d}\n", .{resp.getStatusCode()});

    // Examine the request we sent.
    // The LastHeader property stores the HTTP request header of the most recent request sent,
    // and in this instance, the response body mirrors the request body.
