I am using python flask, and pusher API for live messaging on my website.
Everything works as expected in development flask server, but the trouble starts when I switch to gunicorn and nginx live servers.
When I trigger pusher event I get an error 500.
Maybe I have to configure something in my nginx.conf file?
/etc/nginx/sites-enabled/đir
server {
listen 80;
server_name 172.104.228.152;
location /static {
alias /home/marko/Đir/đir/static;
}
location / {
proxy_pass http://localhost:8000;
include /etc/nginx/proxy_params;
proxy_redirect off;
}
}.
This is the error message:

I managed to solve this by setting pusher ssl = False.
It is really strange solution, nowhere to be sad in documentation or error log.

I have a strange problem when using flask + TikTok API that I can't figure out.
I have the following code:
from flask import Flask
from flask_restful import Resource, Api
from TikTokApi import TikTokApi
tikTokApi = TikTokApi()
app = Flask(__name__)
api = Api(app)
#app.errorhandler(404)
def page_not_found(e):
return {'status': 'fail'}, 404
class TikTokProfile(Resource):
def get(self):
profileResponse = tikTokApi.getUserObject('rosiethepygmygoat')
return {'user' : profileResponse}
class TikTokMedia(Resource):
def get(self):
data = tikTokApi.getUserObject('rosiethepygmygoat')
response = tikTokApi.userPage(data["id"],data["secUid"])
return response
api.add_resource(TikTokProfile, '/profile')
api.add_resource(TikTokMedia, '/media')
if __name__ == '__main__':
app.run(debug=True)
When I visit /profile I get the user object, but when I try to get his user page via the /media route I get the following error:
INFO:werkzeug:127.0.0.1 - - [08/Jan/2021 09:20:45] "GET /media HTTP/1.1" 500 -

I thought that there is an issue with the TikTokApi package but when I try the same code outside the flask resource:
data = tikTokApi.getUserObject('rosiethepygmygoat')
response = tikTokApi.userPage(data["id"],data["secUid"])
print(response)
I get the object I need.
So am I missing a specific configuration for flask or something else? Any insights will be much appreciated.
Run your flask application using this comands:
flask run --without-threads
Hello I am trying to connect to a neo4j database with py2neo.
This code works so far:
graph = Graph(bolt=True, host='***',
bolt_port=***,
http_port=***,
user='***',
password='***')
But when I protect my IP address with a password over HTTP then I can't connect and I don't know how to authorize py2neo to connect.
Does anyone know how I can solve this? :)
Edit :
When I open the ip in a web browser i need to input a user and a password before i can see the neo4j browser - and I do not now how to input these credentias with py2neo (because it seems that this is my problem)

I am fairly new to redis and using configuring redis with flask app.
i have edited redis.conf file and uncommented requirepass
requirepass foobared
and I am able to get into redid-cli using this password.
like this ./redis-cli -h 127.0.0.1 -p 6379 -a foobared
but when I try to initialise an object of Redis class by passing in the password,
>>> import os
>>> import redis
>>> from flask import Flask
>>> from redis import Redis
>>> app = Flask('weatherApp')
>>> app.config["REDIS_HOST"] = os.getenv("REDIS_HOST")
>>> app.config["REDIS_PORT"] = os.getenv("REDIS_PORT")
>>> app.config["REDIS_PWD"] = os.getenv("REDIS_PWD")
>>> app
<Flask 'weatherApp'>
>>> app.config
>>> redis = Redis(app.config["REDIS_HOST"], port=app.config["REDIS_PORT"],
... db=0, password=app.config["REDIS_PWD"])
>>> redis.client_list()
I keep getting the error saying:

I am trying to wrote some code using flask let another server can post some data to it and then inside flask, when I receive the call from outside, I would like to make another post to another server.
Below is my code
from flask import Flask, jsonify, request
import json
import requests
app = Flask(__name__)
#app.route("/sendData.json", methods=['POST'])
def receiveImageData():
imageData = request.json
# save data to son file
with open(request.json['image_filename'].split('.')[0] + '.json', 'w+') as f:
json.dump(imageData, f, indent=4)
# post some data to this url
r = requests.post('http://example.com/example.json', son = {'image_filename':'test.jpg', 'image_url': "http://images.come"})
# return json data back for /sendData.json
return jsonify({"status": "success"})
The problem is the last line {'status':'success'} will not return for sendData.json.
How can I fix it or there should be another way to make this happen?
Below is error log from flask
127.0.0.1 - - [03/Aug/2017 14:38:37] "POST /sendData.json HTTP/1.1" 500 -

Try it out with return Response(), 200 at the end of receiveImageData().
EDIT:
I researched a bit. Actually it should work. Try something like:
return jsonify({"success": True}), 202
What are the error messages you get? And is it the same server / API, where you post your data and status: success?
I have an issue since I added gevent to my flask project: the page spawning greenlets always timeout / bad gateway.
The part of code causing this issue is this: https://github.com/Kyria/LazyBlacksmith/blob/master/lazyblacksmith/views/ajax.py#L145-L221
Here what i've tested:
Running my flask app with python app.py : works fine with or without gevent/greenlets.
Running behind uwsgi without gevent/greenlet : works fine.
Running behind uwsgi with gevent/greenlet : fails.
So, after searching for a while, reading uwsgi doc, i tried to add some stuff to my uwsgi conf :
loop = async
async = 10
greenlet = true
ugreen = true
After restarting my uwsgi, i didn't have to wait for error, the Bad Gateway was really quick, but with an error in the log this time:

MemoryError
I also tried to add the following in my uwsgi app conf :
gevent = 10
gevent-monkey-patch = true
limit-as = 512
And i tried to increase the timeout in nginx uwsgi_read_timeout 300, but it didn't change anything...
My uwsgi conf is the following:
# lazyblacksmith.ini file
[uwsgi]
chdir = /home/lazyblacksmith/LazyBlacksmith
home = /home/lazyblacksmith/LazyBlacksmith/env/
callable = app
wsgi-file = app.py
master = true
processes = 10
socket = /home/lazyblacksmith/LazyBlacksmith/env/lazyblacksmith.socket
chmod-socket = 664
vacuum = true
uid = lazyblacksmith
gid = www-data
My nginx conf :
upstream lbflask {
server unix:/home/lazyblacksmith/LazyBlacksmith/env/lazyblacksmith.socket;
}
# configuration of the server
server {
# the port your site will be served on
listen 80;
# the domain name it will serve for
server_name site.com; #
charset utf-8;
location /static {
alias /home/lazyblacksmith/LazyBlacksmith/lazyblacksmith/static;
include /etc/nginx/mime.types;
}
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass lbflask;
include /etc/nginx/uwsgi_params; # the uwsgi_params file you installed
}
}
I don't find anything relevant anymore :/ I think i'll end up moving my gevent stuff in tasks (with celery), but i still want to understand what is my problem...
For information:
Debian 8
uwsgi 2.0.7-debian
nginx/1.6.2
python 2.7.9
gevent 1.1rc2
greenlet 0.4.9
Thank you !
