Question

我的yaml文件：

application: testprogram
version: 1
runtime: python
api_version: 1

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

我的python文件：

import webapp2

class MainPage(webapp2.RequestHandler):
    def get(self):
        self.reponse.headers['Content-Type'] = 'text/plain'
        self.response.out.write("Hurray for cake!")

app = webapp2.WSGIApplication([('/', MainPage)],debug=True)

服务器已启动。本地主机已启动。但没有任何东西被写出来。我正在做udacitys课程所以我刚刚开始。什么可以挂起来。一直在检查文档但仍然丢失。

Answer 1

在.yaml文件中，将路由处理程序指向main.app（而不是main.py）。

你的python文件中也有拼写错误。响应缺少第一个＆＃39;

：

self.reponse.headers['Content-Type'] = 'text/plain'

应该是

self.response.headers['Content-Type'] = 'text/plain'

Answer 2

处理程序部分的app.yaml文件中存在问题：

此致：

application: testprogram
version: 1
runtime: python
api_version: 1

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

但你应该：

application: testprogram
version: 1
runtime: python27
api_version: 1
threadsafe: yes

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

python中的response.out.write，谷歌应用引擎不在本地主机上显示
