Duplicate curl -u user:password with Chilkat HTTP

See more HTTP Misc Examples

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

void ChilkatSample(void)
    {
    bool success = false;

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

    CkHttpW http;
    CkHttpRequestW req;

    // The AddHeader method corresponds to the curl "-H" argument.
    req.AddHeader(L"Accept",L"application/json");
    req.AddHeader(L"Accept-Language",L"en_US");

    // The curl "-d" argument specifies the HTTP request body.  In this case,
    // we're sending an application/x-www-form-urlencoded request, and therefore
    // the body contains the URL-encoded query parameters.
    req.AddParam(L"grant_type",L"client_credentials");

    http.put_Login(L"PAYPAL_REST_API_CLIENT_ID");
    http.put_Password(L"PAYPAL_REST_API_SECRET");

    // Sends a POST request where the Content-Type is application/x-www-form-urlencoded
    req.put_HttpVerb(L"POST");
    req.put_ContentType(L"application/x-www-form-urlencoded");

    CkHttpResponseW resp;
    success = http.HttpReq(L"https://api.sandbox.paypal.com/v1/oauth2/token",req,resp);
    if (success == false) {
        wprintf(L"%s\n",http.lastErrorText());
        return;
    }

    if (resp.get_StatusCode() != 200) {
        wprintf(L"Error status code: %d\n",resp.get_StatusCode());
        wprintf(L"%s\n",resp.bodyStr());
        return;
    }

    // The JSON response is in the resp BodyStr property
    wprintf(L"%s\n",resp.bodyStr());
    wprintf(L"-- Success.\n");
