Examine HTTP Response Status Code and Text

See more REST Examples

Demonstrates how to examine the HTTP response status code and text when using the REST object. C#

bool success = false;

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

Chilkat.Rest rest = new Chilkat.Rest();

//  We're going to check https://authenticationtest.com/HTTPAuth/
bool bTls = true;
int port = 443;
bool bAutoReconnect = true;
success = rest.Connect("authenticationtest.com",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  Send a GET request
string responseText = rest.FullRequestNoBody("GET","/HTTPAuth/");
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  The start line of an HTTP response, called the status line, contains the following information:
//  
//      The protocol version, usually HTTP/1.1.
//      A status code, indicating success or failure of the request. Common status codes are 200, 404, or 302
//      A status text. A brief, purely informational, textual description of the status code to help a human understand the HTTP message.
//  
//  A typical status line looks like: HTTP/1.1 404 Not Found.

//  The ResponseStatusCode property contains the integer response code:
Debug.WriteLine("Response status code = " + Convert.ToString(rest.ResponseStatusCode));

//  The ResponseStatusText property contains the text (if any) that follows the status code on the status line.
Debug.WriteLine("Response status text = " + rest.ResponseStatusText);

//  In this case, the sample output is:
//  
//  Response status code = 401
//  Response status text = Unauthorized
