带 flask 的 Python CGI 不起作用

Question

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 然后我得到这个错误:

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

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

KeyError: 'SERVER_NAME'

为什么？

Answer 1

.cgi文件必须保留，因为它在 Flask 文档中提到。

也许你可以引用这个——
