Hi<p>I have a corner case :-)<p>A library client do a POST request on my server, with 2 headers :
> Content-type: application/json
> Content-length: 0<p>So ATM the server response is 400 (bad request) because json is invalid<p>So the question is :
When the content-length of a request is 0, should we parse the body or not ?
To my mind, as long as the Content-type header is set, the server should try to parse the body accordingly.<p>In the case of JSON, an empty body cannot be a JSON representation, but for other formats an empty body can have a meaning.
What does it matter?<p>What you should do is have the error messages be the same for detecting a length 0 submission and of attempting to parse the empty string as JSON.<p>You can think of the check for length==0 and length==1 as a sort of optimization (no JSON document can be 1 byte long), rather than a corner case.
