Now I use flask to develop web app.
But at first it works well,after operating web page for a while,the flask back-end shows error like these:
File "/usr/lib64/python2.6/BaseHTTPServer.py", line 329, in handle
self.handle_one_request()
File "/usr/lib/python2.6/site-packages/werkzeug/serving.py", line 251, in handle_one_request
return self.run_wsgi()
File "/usr/lib/python2.6/site-packages/werkzeug/serving.py", line 193, in run_wsgi
execute(self.server.app)
File "/usr/lib/python2.6/site-packages/werkzeug/serving.py", line 184, in execute
write(data)
File "/usr/lib/python2.6/site-packages/werkzeug/serving.py", line 152, in write
self.send_header(key, value)
File "/usr/lib64/python2.6/BaseHTTPServer.py", line 390, in send_header
self.wfile.write("%s: %s\r\n" % (keyword, value))
IOError: [Errno 32] Broken pipe
My app run on port 5000 app.run(debug=True,port=5000)
,
I use nginx as web server,and set proxy_pass http://127.0.0.1:5000
in nginx config file.
Now I really don't know where is the wrong,I use session['email'] = request.form['email']
and in other file I use email = session.get('email')
.
Is this usage right? How to set session active period?
or any other reason cause this error ?
then I set app.run(debug=False,port=5000)
,it shows new error
File "/usr/lib64/python2.6/SocketServer.py", line 671, in finish
self.wfile.flush()
File "/usr/lib64/python2.6/socket.py", line 303, in flush
self._sock.sendall(buffer(data, write_offset, buffer_size))
socket.error: [Errno 32] Broken pipe
why ?
Please help me,thks.
The built-in werkzeug server is not capable of handling the remote end closing the connection while the server is still churing its content out.
instead of app.run(debug=True,port=5000)
try
from gevent.wsgi import WSGIServer
http_server = WSGIServer(('', 5000), app)
http_server.serve_forever()
or if you are using nginx, use it with uwsgi as described here
It is rather a werkzeug
issue I would argue
