成功订阅后处理来自Facebook的通知请求

我正在尝试实施Facebook实时API。我已经成功添加了订阅。（请访问网址以了解如何... What is verify token in Facebook Realtime API ）成功订阅后处理来自Facebook的通知请求

但我不会从FB得到任何通知。每当用户进行任何更改时，FB都会对我的callback_url进行POST调用（我检查了我的站点的访问日志）。但我无法将数据写入文件。

我的代码是：

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.')

根据日志条目的Facebook订阅回调得到状态403 Forbidden并且这发生在您的代码运行之前。

确保您的应用程序能够达到/fb_subscriptions且代码正在运行。

您可能需要使用你的Web服务器的增加日志级别，为什么请求被阻塞，以获得更多的详细信息...
