Inspect HTTP Request Header

Demonstrates the LastHeader property. Zig

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

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

    const http = try chilkat.Http.init();
    defer http.deinit();

    const url = "https://chilkatsoft.com/echo_request_body.asp";
    const json = "{\"greeting\":\"Hello World\"}";

    // Send a POST with the JSON in the HTTP request body.
    const resp = try chilkat.HttpResponse.init();
    defer resp.deinit();
    http.httpStr("POST", url, json, "utf-8", "application/json", resp) catch {
        std.debug.print("{s}\n", .{try http.getLastErrorText(alloc)});
        return;
    };

    // Examine the HTTP request header we just sent.
    std.debug.print("{s}\n", .{try http.getLastHeader(alloc)});

    // Output:

    // POST /echo_request_body.asp HTTP/1.1
