[英]response.out.write in python, google app engine not displaying on local host
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)
从服务器:
$ dev_appserver.py testprogram

服务器断了。 本地主机已启动。 但是什么都没有写出来。 我正在上大学课程,所以我才刚刚开始。 挂断电话可能是什么。 正在检查文档,但仍然丢失。
在.yaml
文件中,将路由处理程序指向main.app(而不是main.py)。
您的python文件中也有错字。 响应缺少第一个“ s”:
self.reponse.headers['Content-Type'] = 'text/plain'
应该
self.response.headers['Content-Type'] = 'text/plain'
您在处理程序部分的app.yaml
文件中存在问题:
您的:
application: testprogram
version: 1
runtime: python
api_version: 1
handlers:
- url: /.*
script: main.py
但您应该具有:
application: testprogram
version: 1
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /.*
script: main.app
