docs: the request body, if this is a POST request
  
          this tries to do the right thing with the body, so if you have set the body and
          the content type is json, then it will return the body json decoded, if you need
          the original string body, use body
  
          example --
  
              self.body = '{"foo":{"name":"bar"}}'
              b = self.body_kwargs # dict with: {"foo": { "name": "bar"}}
              print self.body # string with: '{"foo":{"name":"bar"}}'
