Go

Example: Http.SetCookieXml method

Demonstrates the SetCookieXml method. Go

    success := false

    http := chilkat.NewHttp()

    http.SetSaveCookies(true)
    http.SetCookieDir("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.SetSendCookies(false)

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

    // Examine the LastResponseHeader to see the cookies that were received:
    fmt.Println(http.LastResponseHeader())
    fmt.Println("----------------------------------")

    // 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.
    fmt.Println(*http.GetCookieXml("google.com"))
    fmt.Println("----------------------------------")

    // 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:
    httpB := chilkat.NewHttp()

    httpB.SetSaveCookies(true)
    httpB.SetCookieDir("c:/temp/cookie_cache")
    httpB.SetSendCookies(true)

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

    // Examine the LastHeader to see the contents of the Cookie header field.
    fmt.Println(httpB.LastHeader())
    fmt.Println("----------------------------------")

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

    httpC := chilkat.NewHttp()

    httpC.SetSaveCookies(true)
    // Do not save cookies to files, just keep them in memory.
    httpC.SetCookieDir("memory")
    httpC.SetSendCookies(true)

    sbCookiesXml := chilkat.NewStringBuilder()
    success = sbCookiesXml.LoadFile("c:/temp/cookie_cache/google_com.xml","utf-8")
    if success == false {
        fmt.Println(sbCookiesXml.LastErrorText())
        http.DisposeHttp()
        httpB.DisposeHttp()
        httpC.DisposeHttp()
        sbCookiesXml.DisposeStringBuilder()
        return
    }

    success = httpC.SetCookieXml("google.com",*sbCookiesXml.GetAsString())
    if success == false {
        fmt.Println(httpC.LastErrorText())
        http.DisposeHttp()
        httpB.DisposeHttp()
        httpC.DisposeHttp()
        sbCookiesXml.DisposeStringBuilder()
        return
    }

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

    // Examine the LastHeader to see the contents of the Cookie header field.
    fmt.Println(httpC.LastHeader())

    http.DisposeHttp()
    httpB.DisposeHttp()
    httpC.DisposeHttp()
