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. Ruby

require 'chilkat'

success = false

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

rest = Chilkat::CkRest.new()

# Connect to the web server
bTls = true
port = 443
bAutoReconnect = true
success = rest.Connect("www.chilkatsoft.com",port,bTls,bAutoReconnect)
if (success != true)
    print rest.lastErrorText() + "\n";
    exit
end

# Setup a file stream for the download
fileStream = Chilkat::CkStream.new()
fileStream.put_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.
expectedStatus = 200
rest.SetResponseBodyStream(expectedStatus,true,fileStream)

responseStr = rest.fullRequestNoBody("GET","/images/starfish.jpg")
if (rest.get_LastMethodSuccess() == false)
    # Examine the request/response to see what happened.
    print "response status code = " + rest.get_ResponseStatusCode().to_s() + "\n";
    print "response status text = " + rest.responseStatusText() + "\n";
    print "response header: " + rest.responseHeader() + "\n";
    print "response body (if any): " + responseStr + "\n";
    print "---" + "\n";
    print "LastRequestStartLine: " + rest.lastRequestStartLine() + "\n";
    print "LastRequestHeader: " + rest.lastRequestHeader() + "\n";
    exit
end

print "downloaded starfish.jpg" + "\n";

# 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.
bd = Chilkat::CkBinData.new()
success = rest.FullRequestNoBodyBd("GET","/images/penguins.jpg",bd)
if (success == false)
    # Examine the request/response to see what happened.
    print "response status code = " + rest.get_ResponseStatusCode().to_s() + "\n";
    print "response status text = " + rest.responseStatusText() + "\n";
    print "response header: " + rest.responseHeader() + "\n";
    print "response body (if any): " + bd.getString("utf-8") + "\n";
    print "---" + "\n";
    print "LastRequestStartLine: " + rest.lastRequestStartLine() + "\n";
    print "LastRequestHeader: " + rest.lastRequestHeader() + "\n";
    exit
end

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

print "Success: " + success.to_s() + "\n";
