Question

以下代码生成CGI方法而不是WSGI，如下面的日志所示。这是开发服务器上WSGI应用程序的正常执行吗？如果不是需要更改以使应用程序以WSGI的形式执行？

main.py

import webapp2
import wsgiref.handlers
import logging
from google.appengine.api import users


class HomeHandler(webapp2.RequestHandler):
    def get(self):
        self.response.out.write("Hi World")

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

app.run()

的app.yaml

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

libraries:
- name: webapp2
  version: latest

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

Answer 1

此日志是一个硬编码字符串：

/usr/local/google_appengine/google/appengine/tools/dev_appserver.py:
 1622      sys.modules['__builtin__'] = __builtin__
 1623  
 1624:     logging.debug('Executing CGI with env:\n%s', repr(env))

Answer 2

首先，您应删除此行代码，因为它是incorrect：

app.run()

正如我的评论中所写并且aschmid00指出的那样，可能是一个旧的调试声明。
