angularjs - angular 2 app engine - 前端发布请求到后端

Question

嗨，我有一个 Angular 2 应用程序，我想将其部署到 gae。所以后端我使用的是应用程序引擎python。我正在尝试从角度前端到应用引擎 python 的简单发布请求。所以以下是我的 app.yaml

runtime: python27
api_version: 1
threadsafe: true
service: federation-bipedal-hominids

handlers:
- url: /.*
  script: main.app

- url: (.*)/
  static_files: federation-bipedal-hominids/src/app\1/index.html
  upload: app

- url: (.*)
  static_files: app/home\1
  upload: app

主文件

import json
import webapp2
import time


# app = StaticURLParser("federation-bipedal-hominids")

def AsDict():
  return {"Hello World !": "try now"}

class RestHandler(webapp2.RequestHandler):

  def dispatch(self):
    #time.sleep(1)
    super(RestHandler, self).dispatch()


  def SendJson(self, r):
    self.response.headers['content-type'] = 'text/plain'
    self.response.write(json.dumps(r))

class HelloWorld(RestHandler):

  def post(self):

    r = AsDict()
    self.SendJson(r)

class QueryHandler(RestHandler):

  def get(self):

    r = AsDict()
    self.SendJson(r)


app = webapp2.WSGIApplication([


('/HelloWorld', HelloWorld)
], debug=True)

现在，我应该如何从角度前端做到这一点？
