{"test": "test", "args": ["http://example.com/api", "POST", "Content-Type: application/json\nContent-Length: 32", "{\"id\": \"Cleese\", \"name\": \"John\"}"]}

POST /json HTTP/1.1

User-Agent: curl/7.49.1
Accept: */*
Content-Type:application/json
Content-Length: 32

{"id": "Cleese", "name": "John"}
