Example: Http.SetCookieXml method

Demonstrates the SetCookieXml method. Swift

func chilkatTest() {
    var success: Bool = false

    let http = CkoHttp()!

    http.saveCookies = true
    http.cookieDir = "c:/temp/cookie_cache"
    // For this initial request, we are not sending cookies.
    // We are starting a new (cookie) session and saving the cookies we receive.
    http.sendCookies = false

    // Do a request that establishes and saves cookies in files in the cookie directory.
    var html: String? = http.quickGetStr(url: "https://google.com/")

    // Examine the LastResponseHeader to see the cookies that were received:
    print("\(http.lastResponseHeader!)")
    print("----------------------------------")

    // 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

    // Examine the cookies received in the above request.
    print("\(http.getCookieXml(domain: "google.com")!)")
    print("----------------------------------")

    // Sample output.

    // <?xml version="1.0" encoding="utf-8"?>
    // <cookies>
    //     <cookie key=".google.com,/,AEC" v="0" expire="Mon, 23-Feb-2026 19:05:20 GMT" secure="yes">
    //         <AEC>AVh_V2gL8QzTdFGYq6_rS6ktBfqm8WNG3pzHxS2nTZD5i23dRBau2c4ZRA</AEC>
    //     </cookie>
    //     <cookie key=".google.com,/,NID" v="0" expire="Thu, 26-Feb-2026 19:05:20 GMT">
    //         <NID>525=SuLcnaSkFqF4Jz_jLEq4kt_f3MY2Xro1VDoVzLKvp8XHcW2UHuLKJSr55iDeW0NiRIPXoAwJWF1-YNl29unX2xfhEWsS5BhbuK_2DXdD9cTOmn5BSENMhZasxeJ71mEP2PQRMXBndqnl41DhblC2jjdac_so4TESIll1B0GCVe9wRFjqI6DTZItRCj61BHmr1_RAQi0_jrh_ihn6KYtIFEY7</NID>
    //     </cookie>
    // </cookies>

    // -------------------------------------------------------------------------------------------
    // 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:
    let httpB = CkoHttp()!

    httpB.saveCookies = true
    httpB.cookieDir = "c:/temp/cookie_cache"
    httpB.sendCookies = true

    // The cookies from the cache are sent.
    html = httpB.quickGetStr(url: "https://google.com/")

    // Examine the LastHeader to see the contents of the Cookie header field.
    print("\(httpB.lastHeader!)")
    print("----------------------------------")

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

    let httpC = CkoHttp()!

    httpC.saveCookies = true
    // Do not save cookies to files, just keep them in memory.
    httpC.cookieDir = "memory"
    httpC.sendCookies = true

    let sbCookiesXml = CkoStringBuilder()!
    success = sbCookiesXml.loadFile(path: "c:/temp/cookie_cache/google_com.xml", charset: "utf-8")
    if success == false {
        print("\(sbCookiesXml.lastErrorText!)")
        return
    }

    success = httpC.setCookieXml(domain: "google.com", cookieXml: sbCookiesXml.getAsString())
    if success == false {
        print("\(httpC.lastErrorText!)")
        return
    }

    html = httpC.quickGetStr(url: "https://google.com/")

    // Examine the LastHeader to see the contents of the Cookie header field.
    print("\(httpC.lastHeader!)")
