IWinHttpRequest::Status property

The Status property retrieves the HTTP status code from the last response.

This property is read-only.

Syntax


HRESULT get_Status(
  [out, retval] long *Status
);

Property value

A value of type long that receives the returned status code.

Error codes

The return value is S_OK on success or an error value otherwise.

Remarks

The results of this property are valid only after the Send method has successfully completed. For a list of status codes see HTTP Status Codes.

Note  For Windows XP and Windows 2000, see the Run-Time Requirements section of the WinHttp start page.
 

Examples

The following example shows how to open an HTTP connection, send an HTTP request, display the Status and StatusText, and read the response headers. This example must be run from a command prompt.

The following scripting example shows how to open an HTTP connection, send an HTTP request, display the Status and StatusText, and read the response text.


// Instantiate a WinHttpRequest object.
var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1");

// Initialize an HTTP request.  
WinHttpReq.Open("GET", "http://www.microsoft.com", false);

// Send the HTTP request.
WinHttpReq.Send(); 

// Display the status.
WScript.Echo( WinHttpReq.Status + " - " + WinHttpReq.StatusText);

// Display the date header.
WScript.Echo( WinHttpReq.GetAllResponseHeaders());
