带Flask的Python CGI无法正常工作 [英] Python CGI with flask not working

问题描述

我刚刚开始在Godaddy入门包上共享托管.我按照此处的说明使用FLASK设置CGI: http://flask.pocoo.org/docs/deploying/cgi/

但是当我运行cgi.py时，出现此错误:

  Traceback(最近一次通话最近):运行中的文件"/home/railwayapi/python/lib/python3.4/wsgiref/handlers.py"，第137行self.result =应用程序(self.environ，self.start_response)在__call__中的文件"/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py"中，第1836行返回self.wsgi_app(环境，start_response)wsgi_app中的文件"/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py"，行1812ctx = self.request_context(环境)在request_context中，文件"/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py"第1773行返回RequestContext(self，environ)__init__中的第224行的文件"/home/railwayapi/flasker/lib/python3.4/site-packages/flask/ctx.py"self.url_adapter = app.create_url_adapter(self.request)在create_url_adapter中，文件"/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py"，行1602server_name = self.config ['SERVER_NAME'])在bind_to_environ中的文件"/home/railwayapi/flasker/lib/python3.4/site-packages/werkzeug/routing.py"，行1165server_name =环境['SERVER_NAME']KeyError:"SERVER_NAME"状态:500内部服务器错误内容类型:文本/纯文本内容长度:59 

这是主要部分:server_name = environ ['SERVER_NAME']

KeyError:"SERVER_NAME"

为什么?

解决方案

必须保存Flask文档中提到的 .cgi 文件.

也许您可以参考这个-

I have just started shared hosting on godaddy starter pack. I followed the instructions here to set up CGI with FLASK: http://flask.pocoo.org/docs/deploying/cgi/

But when i run the cgi.py then i get this error:

Traceback (most recent call last):
  File "/home/railwayapi/python/lib/python3.4/wsgiref/handlers.py", line 137, in run
    self.result = application(self.environ, self.start_response)
  File "/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py", line 1836, in __call__
    return self.wsgi_app(environ, start_response)
  File "/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py", line 1812, in wsgi_app
    ctx = self.request_context(environ)
  File "/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py", line 1773, in request_context
    return RequestContext(self, environ)
  File "/home/railwayapi/flasker/lib/python3.4/site-packages/flask/ctx.py", line 224, in __init__
    self.url_adapter = app.create_url_adapter(self.request)
  File "/home/railwayapi/flasker/lib/python3.4/site-packages/flask/app.py", line 1602, in create_url_adapter
    server_name=self.config['SERVER_NAME'])
  File "/home/railwayapi/flasker/lib/python3.4/site-packages/werkzeug/routing.py", line 1165, in bind_to_environ
    server_name = environ['SERVER_NAME']
KeyError: 'SERVER_NAME'
Status: 500 Internal Server Error
Content-Type: text/plain
Content-Length: 59

This is the main part: server_name = environ['SERVER_NAME']

KeyError: 'SERVER_NAME'

Why?

解决方案

The .cgi file has to remain as it is mentioned in the Flask documentation.

Maybe you can refer to this -
