Question

我正在尝试使用Python 3.4.3和Bottle 0.12.8来使用cgi运行简单的Web服务。我从Linux系统运行以下脚本。我能够在没有CGI的情况下运行相同的服务。

======================================
import bottle
from bottle import route, run, request, response

host = 'XXXX'
port = '8080'
debug = 'False'

@route('/hello/',  method=['OPTIONS','GET'])
def hello():
    return("Success")

bottle.run(host=host, port=port,debug=debug,server='cgi')
#bottle.run(host=host, port=port,debug=debug)
======================================

当我使用CGI-

运行服务时，我得到以下错误

Traceback (most recent call last):
  File "/usr/local/lib/python3.4/site-packages/bottle.py", line 858, in _handle
    route, args = self.router.match(environ)
  File "/usr/local/lib/python3.4/site-packages/bottle.py", line 413, in match
    verb = environ['REQUEST_METHOD'].upper()
KeyError: 'REQUEST_METHOD'

Any pointers would help. Thanks

您收到此错误，因为basic CGI HTTP server in Python仅支持GET，HEAD和POST命令。 CGI服务器在尝试验证OPTIONS命令时抛出KeyError。如果要在服务器代码中使用OPTIONS方法，则需要自己实现或切换到其他服务器。

Python 3.4.3＆amp;带CGI的瓶子 - 环境[＆＃39; REQUEST_METHOD＆＃39;]
