Explaining the Rest ClearResponseBodyStream Method

See more Azure Cloud Storage Examples

The ClearResponseBodyStream method would be needed if your applicaiton called SetResponseBodyStream to send the response to a stream for one request, but then wants to subsequently do something else. The application must call ClearResponseBodyStream to no longer send responses to the stream. 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();

//  Connect to the web server
bool bTls = true;
int port = 443;
bool bAutoReconnect = true;
success = rest.Connect("www.chilkatsoft.com",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  Setup a file stream for the download
Chilkat.Stream fileStream = new Chilkat.Stream();
fileStream.SinkFile = "qa_output/starfish.jpg";

//  Indicate that the call to FullRequestNoBody should send the response body
//  to fileStream if the response status code is 200.
//  If a non-success response status code is received, then nothing
//  is streamed to the output file and the error response is returned by FullRequestNoBody.
int expectedStatus = 200;
rest.SetResponseBodyStream(expectedStatus,true,fileStream);

string responseStr = rest.FullRequestNoBody("GET","/images/starfish.jpg");
if (rest.LastMethodSuccess == false) {
    //  Examine the request/response to see what happened.
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));
    Debug.WriteLine("response status text = " + rest.ResponseStatusText);
    Debug.WriteLine("response header: " + rest.ResponseHeader);
    Debug.WriteLine("response body (if any): " + responseStr);
    Debug.WriteLine("---");
    Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine);
    Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

Debug.WriteLine("downloaded starfish.jpg");

//  Clear the response body stream previously set in the call to SetResponseBodyStream.
rest.ClearResponseBodyStream();

//  Download something else, but this time send the response body to bd.
Chilkat.BinData bd = new Chilkat.BinData();
success = rest.FullRequestNoBodyBd("GET","/images/penguins.jpg",bd);
if (success == false) {
    //  Examine the request/response to see what happened.
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));
    Debug.WriteLine("response status text = " + rest.ResponseStatusText);
    Debug.WriteLine("response header: " + rest.ResponseHeader);
    Debug.WriteLine("response body (if any): " + bd.GetString("utf-8"));
    Debug.WriteLine("---");
    Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine);
    Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

//  Save the contents of bd to a file.
success = bd.WriteFile("qa_output/penguins.jpg");

Debug.WriteLine("Success: " + Convert.ToString(success));
