From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com&gt; in test mode, you can user curl or HttpRequester to try as follow. $ curl -u <user> -H 'Accept: application/json' -H 'Content-type: application/json' http://localhost:8000/templates/test-template-4 -X PUT -d '' kimchi will throw HTTPError: (400, 'Unable to parse JSON request') Now remove the check Content-Length in request headers. No Content-Length in request headers means this request without body. GET and DELETE methods allow a request without body. But PUT and POST methods require body in request. After remove this check, new check for the length of body. And also now we have decide not to pass parameters by body for GET method. That means GET will not call parse_request.
