python flask 报错求助！

File "/obj1/wechat/env/local/lib/python2.7/site-packages/flask/app.py", line 1836, in call 

    return self.wsgi_app(environ, start_response)
    
File "/obj1/wechat/env/local/lib/python2.7/site-packages/flask/app.py", line 1821, in wsgi_app 

    return response(environ, start_response)
    
File "/obj1/wechat/env/local/lib/python2.7/site-packages/werkzeug/wrappers.py", line 1200, in call 

    app_iter, status, headers = self.get_wsgi_response(environ) 
    
File "/obj1/wechat/env/local/lib/python2.7/site-packages/werkzeug/wrappers.py", line 1188, in get_wsgi_response 

    headers = self.get_wsgi_headers(environ) 
    
File "/obj1/wechat/env/local/lib/python2.7/site-packages/werkzeug/wrappers.py", line 1110, in get_wsgi_headers 

    current_url = get_current_url(environ, root_only=True) 
    
File "/obj1/wechat/env/local/lib/python2.7/site-packages/werkzeug/wsgi.py", line 70, in get_current_url 

    tmp = [environ['wsgi.url_scheme'], '://', get_host(environ, trusted_hosts)]

KeyError: 'wsgi.url_scheme'

请问这是什么问题引起的？

response 格式不符合预期吧，解析的时候发现这个 key 不存在。
