Class EmptyContent

java.lang.Object
  com.google.api.client.http.EmptyContent

All Implemented Interfaces:

HttpContent

public class EmptyContent
extends Object
implements HttpContent

Empty HTTP content of length zero just to force HttpRequest.execute() to add the header Content-Length: 0.

Note that there is no Content-Length header if the HTTP request content is null . However, when making a request like PUT or POST without a Content-Length header, some servers may respond with a 411 Length Required error. Specifying the Content-Length: 0 header may work around that problem.

Since:

1.11
