title: flask-restful having a get/<id> and post with json in the same class
body: <p>The get method on user works if the # api.add_resource(User, '/user/')
  line is uncommented, and the other api.add_resource is. 
  The inverse of that is true to make the post method work.</p>
  
  <p>How can I get both of these paths to work?</p>
  
  <pre><code>from flask import Flask, request
  from flask.ext.restful import reqparse, abort, Api, Resource
  import os
  # set the project root directory as the static folder, you can set others.
  app = Flask(__name__)
  api = Api(app)
  
  class User(Resource):
  
      def get(self, userid):
          print type(userid)
          if(userid == '1'):
              return {'id':1, 'name':'foo'}
          else:
              abort(404, message="user not found")
  
      def post(self):
          # should just return the json that was posted to it
          return request.get_json(force=True)
  
  api.add_resource(User, '/user/')
  # api.add_resource(User, '/user/&lt;string:userid&gt;')
  
  if __name__ == "__main__":
      app.run(debug=True)
  </code></pre>
