Example: Http.SetCookieXml method

Demonstrates the SetCookieXml method. Zig

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

    // We are starting a new (cookie) session and saving the cookies we receive.

    var html: [:0]const u8 = try http.quickGetStr(alloc, "https://google.com/");

    std.debug.print("{s}\n", .{try http.getLastResponseHeader(alloc)});
    std.debug.print("----------------------------------\n", .{});

    // We can see the following Set-Cookie response header fields:

    // Set-Cookie: AEC=AVh_V2h-fsL2-****; expires=Mon, 23-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; Secure; HttpOnly; SameSite=lax
    // Set-Cookie: NID=525=XC_cL****Hn7-WONX; expires=Thu, 26-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; HttpOnly

    // The following file was created:  c:/temp/cookie_cache/google_com.xml

    std.debug.print("{s}\n", .{try http.getCookieXml(alloc, "google.com")});
    std.debug.print("----------------------------------\n", .{});

    // Sample output.

    // Let's say we want to continue with the session at some later time with a new HTTP object.
    // One way to do it is to simply set the same cookie properties:
    const http_b = try chilkat.Http.init();
    defer http_b.deinit();

    http_b.setSaveCookies(true);
    http_b.setCookieDir("c:/temp/cookie_cache");
    http_b.setSendCookies(true);

    // The cookies from the cache are sent.
    html = try http_b.quickGetStr(alloc, "https://google.com/");

    // Examine the LastHeader to see the contents of the Cookie header field.
    std.debug.print("{s}\n", .{try http_b.getLastHeader(alloc)});
    std.debug.print("----------------------------------\n", .{});

    // -------------------------------------------------------------------------------------------
    // Another way to do it is to explicitly load the cookies from XML
    // and set the cookies for the particular domain.

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

    http_c.setSaveCookies(true);
    // Do not save cookies to files, just keep them in memory.
    http_c.setCookieDir("memory");
    http_c.setSendCookies(true);

    const sb_cookies_xml = try chilkat.StringBuilder.init();
    defer sb_cookies_xml.deinit();
    sb_cookies_xml.loadFile("c:/temp/cookie_cache/google_com.xml", "utf-8") catch {
        std.debug.print("{s}\n", .{try sb_cookies_xml.getLastErrorText(alloc)});
        return;
    };

    http_c.setCookieXml("google.com", try sb_cookies_xml.getAsString(alloc)) catch {
        std.debug.print("{s}\n", .{try http_c.getLastErrorText(alloc)});
        return;
    };

    html = try http_c.quickGetStr(alloc, "https://google.com/");

    // Examine the LastHeader to see the contents of the Cookie header field.
    std.debug.print("{s}\n", .{try http_c.getLastHeader(alloc)});
