Getting “411 Length Required” after a PUT request from HTTP Client

Question

I am working on a Java program that implements an HTTP Client. I test it sending requests to a server. GET, POST and DELETE requests work ok. For example after a POST reques

Answer 1

Yes, the issue related to Content-Length. HTTP Error 411 means

The server refuses to accept the request without a defined Content- Length. The client MAY repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message.

So when you send an empty RequestBody in POST/PUT Method then you also need to send Content-Length:0. So add this header in your request. I don't think this header will cause a problem of you added into Request Object.
