问题
I'm trying to implement Facebook realtime API. I've added a subscription successfully. (PLease visit url to find out how... What is verify token in Facebook Realtime API )
But I'm not getting any notifications from FB. Whenever a user makes any changes, FB makes a POST call to my callback_url(I checkecd the access logs of my site). But I'm not able to write the data to a file.
My CODE IS:
from datetime import datetime
def fb_notifications(request):
handle1=open('/path_to_log_file/smt_logs.log','a+')
handle1.write('\n<<<<<Log accessed at ' + str(datetime.now()) + '>>>>>>')
handle1.close();
if request.GET: (#This is working properly.....)
handle1=open('/var/smt_logs/smt_logs.txt','a+')
handle1.write('\n---------------Subscription STARTS at ' + str(datetime.now()) + ' ----------------------------' + '\n')
handle1.write(str(request))
handle1.write('\n-----------------END--------------------------' + '\n\n')
handle1.close();
code = request.GET.get('hub.challenge')
return HttpResponse(code)
elif request.POST:(#This is not working... Trying to write data to a File....)
handle1=open('/path_to_log_file/smt_logs.log','a+')
handle1.write('\n---Notification STARTS at ' + str(datetime.now()) + ' ---' + '\n')
handle1.write(str(request))
handle1.write('\n---END---' + '\n\n')
handle1.close();
else:
handle1=open('/path_to_log_file/smt_logs.log','a+')
handle1.write('\n---Error at ' + str(datetime.now()) + ' ---' + '\n')
handle1.write('\n---END---' + '\n\n')
handle1.close();
return HttpResponse('Error! Please try again.')

According to log entries Facebook subscription callback get status 403 Forbidden and this happens before your code run.
Ensure you're able to reach /fb_subscriptions for your application and code is running.
You may want to use increase log level of your web-server to get more detailed information why request is blocked...
