Adding Cookies to an HTTP Request

See more HTTP Examples

Demonstrates how to add one or more cookies to an HTTP request. C++

#include <CkHttp.h>
#include <CkHttpRequest.h>
#include <CkHttpResponse.h>

void ChilkatSample(void)
    {
    bool success = false;

    //  This example assumes the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    CkHttp http;

    //  The Cookie header field has this format:
    //  Cookie: name1=value1 [; name2=value2] ...

    //  Build an HTTP POST request:
    CkHttpRequest req;
    req.SetFromUrl("http://www.chilkatsoft.com/echoPost.asp");
    req.put_HttpVerb("POST");

    req.AddParam("param1","value1");
    req.AddParam("param2","value2");

    //  To add cookies to any HTTP request sent by a Chilkat HTTP method
    //  that uses an HTTP request object, add the cookies to the
    //  request object by calling AddHeader.  

    //  Add two cookies:
    req.AddHeader("Cookie","user=\"mary\"; city=\"Chicago\"");

    //  Send the HTTP POST.  
    //  (The cookies are sent as part of the HTTP header.)

    const char *domain = "www.chilkatsoft.com";
    int port = 80;
    bool ssl = false;
    CkHttpResponse resp;
    success = http.HttpSReq(domain,port,ssl,req,resp);
    if (success == false) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    //  Display the HTML body of the response.
    if (resp.get_StatusCode() == 200) {
        //  Show the last HTTP request header sent, which should include
        //  our cookies...
        std::cout << http.lastHeader() << "\r\n";
    }
    else {
        std::cout << "HTTP Response Status = " << resp.get_StatusCode() << "\r\n";
    }

    std::cout << "---------------------" << "\r\n";

    //  Some Chilkat HTTP methods do not use an HTTP request object. 
    //  For these methods, such as for QuickGetStr, cookies (or any HTTP request header) 
    //  are added by calling SetRequestHeader.  
    http.SetRequestHeader("Cookie","user=\"mary\"; city=\"Chicago\"");

    const char *html = http.quickGetStr("http://www.w3.org/");
    if (http.get_LastMethodSuccess() != true) {
        std::cout << http.lastErrorText() << "\r\n";
    }
    else {
        //  Show the last HTTP request header sent, which should include
        //  our cookies...
        std::cout << http.lastHeader() << "\r\n";
    }
