Whenever this view is executed my server showed up with some error which I don't know why! the view which I was executing is
#api_view(['POST'])
def Signin(request):
if request.method == 'POST':
username = request.POST.get('username')
passw = request.POST.get('password')
email = request.POST.get('email')
fullname = request.POST.get('fullname')
college = request.POST.get('college_name')
city = request.POST.get('city')
country = request.POST.get('country')
User.objects.create_user(
username=username, password=passw, email=email)
Userinfo.objects.create(
user_name=username, full_name=fullname, user_email=email, college_name=college, city=city, country=country , varified_user=False)
return Response({'status': 'created'})
And what i know after checking my database is my code is executing till user_name=username, full_name=fullname, user_email=email, college_name=college, city=city, country=country , varified_user=False) because I can see the data which I was inserting, now i don't know what error can cause by return Response({'status': 'created'}). The message in my terminal is

You will want to be using HttpResponse or JsonResponse.

ConnectionResetError: [Errno 54] Connection reset by peer
I realize that this has been posted on extensively over the years, but it seems to me that the consensus on the answer is that it could be one of a few things:
(a) Using a .png instead of an .ico in a favicon
(b) Misusing {% static %}
(c) Misusing event.preventDefault()
Unfortunately for me, none of those things have happened in the last few weeks in my teams commits. So I ask, are there other solutions I may be missing? This is a result of me recently merging with a master development branch.
As I mentioned over here, I had this issue show up while debugging POST DRF api endpoints.
The solution was to add SITE_URL to settings with my localhost and dev server port set, i.e.
SITE_URL = "http://localhost:4000"
Commonly this error is associated with a missing favicon file. But I'm not sure if this change gets around that issue or is due to something else.
For added context, I hit this error while using Pycharm's http request scratch file to debug and validate DRF (django rest framework) endpoints.
The format I was using was:
### Send POST request with json body
POST http://localhost:4000/api/admin/add_node/
Content-Type: application/json
Authorization: Basic admin password
{
"name": "node01",
"username": "username",
"password": "password"
}
I have a flask-socket.io application that is pretty standard:
server: eventlet
I start the app using: socketio.run(app, host='0.0.0.0')
Frequently but not always I have some kind of timeout:

I am not able to interpret this traceback. Can somebody with some experience in flask-socket.io help?
I am not posting any code because I would not know where to start. All files in the traceback are from the installed modules.
EDIT:
I got some more info on the socket.io requests. After the above Exception the following requests are logged:
127.0.0.1 - - [04/Jan/2018 10:10:51] "GET /socket.io/?EIO=3&transport=websocket&sid=f93955151a3a4576b2e96427cc27121e HTTP/1.1" 500 0 60.061493

You may use socketio.run(app, host='0.0.0.0', port=5000, debug=True) if you want to switch in debug mode.
Then you may take a look on the socket.io official documentation website, most especialy on client-api and server-api.
Beause in the httpsserver-options part of the server-api (for javascript), you can see that there is some options when running the server, like:
pingInterval: 10000,
pingTimeout: 5000,
I expect that those arguments could be re-used as kwargs when you run you server with socketio.run(app, host='0.0.0.0', port=5000, debug=True,pingInterval = 10000, pingTimeout= 5000)
And in the flask-socketio documentation, in the "Error Handling" part,there is nice tips to to deal with exceptions
You may add something like
#socketio.on_error_default # handles all namespaces without an explicit error handler
def default_error_handler(e):
pass
Another tips could be to adapt this previous error_handler for timeout issue and re-run the server when this event will be triggered.
You may also note that:
The message and data arguments of the current request can also be inspected with the request.event variable, which is useful for error logging and debugging outside the event handler
You may also use this following code to handle the final socket.timeout: timed out error :
try:
socketio.run(app,...
except socket.error as socketerror:
print("Error: ", socketerror)
To complement a-stefani's answer. Proper way to change pingInterval and pingTimeout in flask-socketio is with:
from flask_socketio import SocketIO
socketio = SocketIO(app,ping_timeout=5,ping_interval=10)
This doesn't work: socketio.run(app, host='0.0.0.0', port=5000, debug=True,pingInterval = 10000, pingTimeout= 5000)
I do a poll once a second, and after some idle time (10min - 1h) the server stops responding. If I press Ctrl-C handler is terminated and the server is back alive. Error after pressing Ctrl-C (while trying to connect with a new client):

As you can see from the last code fragment, it just checks the variable is not defined (process is deleted) and return False during all the idle time. (Message "NONE" in log). The problem is difficult to reproduce.
I use a flask server to serve static files from a server but once in a while the server becomes completely unresponsive, downloading a file keeps loading but never downloads. When I opened up the terminal, I found some weird requests, I hit CTRL + C and the server immediately becomes responsive again and downloads continue. This happens every so often and I have no idea what's causing this and how to prevent it from freezing my flask server, is this someone trying to hack?

I had the same issue. It's common in django/flask apps to hang when running as python server.py, because this in not an optimal environment for them. Only use it for testing purpose. When you're done with it and want to release, you should put it behind a wsgi/uwsgi + apache/nginx and your problem will go away.

I have a project with Django I am working on where I want to stream some mp3 files.
I have this same issue:
Streaming mp3 files with django, read from a page with <audio>
Let me explain: I want stream an ogg with Django, and with an <audio> tag in my html page
I have a url like domain.tld/song/show/X/, where X is the id of my song.
I can stream with VLC (directly with the file path), I can stream during test, (I write what I receive and read it with VLC).
But when I open my browser and load my home page domain.tld where I have and <\audio\> balise with url domain.tld/song/show/1/, I get a big broken pipe, as if my client closed the connection.
I read on others post that some problems was resolved when they put server in production. So I push my app on server, use apache, with the django.wgsi like on djangoproject.com.
I am running python 2.7.3 on Debian 7 with Django version 1.5.
there my code:
Song/views.py
def playAudioFile(request, pk):
f = get_stream_song(pk)# return a pipe from pipes.Template
l = f.read() # the file is an ogg get by pydub.com
f.close()
size_read = 550000
sr = size_read
while sr == size_read:
print "rep"
r = l[:size_read]
l=l[size_read:]
sr = len(r)
yield r
time.sleep(0.1)
#url : ~/song/show/X/
##login_required
def show_song(request, pk):
return StreamingHttpResponse(playAudioFile(request, pk), mimetype='audio/ogg',)
In my HTML, I just have that:
<audio controls height="100" width="100" preload="auto">
<source src="/.../song/show/1/" type="audio/ogg">
<embed height="50" width="100" src="/.../song/show/1/">
</audio>
The error looks like:

May be I am crossing your existing solution, i have a suggestion, for mp3 streaming use nginx/apache server, these days there is solution known as sendfile, for example in your case on django view
def send_file_header(server_type):
header = "X-Sendfile" if server_type == "apache" else "X-Accel-Redirect"
return header
#login_required
def show_song(request, pk):
res = HttpResponse()
path = "/path/to/secret/x.mp3"
response[send_file_header('nginx')] = path
response['Content-Type']= "application/octet-stream"
response['Content-Disposition'] = "attachment; filename=\"x.mp3\""
return response
