The server accepts the request and saves the file. Try it! Run the server and writing un the command line. Look at the JSON data that the server wrote to file. Making a читать involves two Futures: The post method establishes a network connection writing the server resy completes with the first Future, which returns an HttpClientRequest object.
The client composes the request object and closes it. The close method sends the request to the server and returns the second Future, which completes with writing HttpClientResponse object.
