成功訂閱後處理來自Facebook的通知請求

我正在嘗試實施Facebook實時API。我已經成功添加了訂閱。（請訪問網址以瞭解如何... What is verify token in Facebook Realtime API ）成功訂閱後處理來自Facebook的通知請求

但我不會從FB得到任何通知。每當用戶進行任何更改時，FB都會對我的callback_url進行POST調用（我檢查了我的站點的訪問日誌）。但我無法將數據寫入文件。

我的代碼是：

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.')

根據日誌條目的Facebook訂閱回調得到狀態403 Forbidden並且這發生在您的代碼運行之前。

確保您的應用程序能夠達到/fb_subscriptions且代碼正在運行。

您可能需要使用你的Web服務器的增加日誌級別，爲什麼請求被阻塞，以獲得更多的詳細信息...

非常感謝！我沒有注意到它扔403（禁止）..... 這是因爲CSRF .... 所以爲了避免這種錯誤在python ....使用@csrf_exempt裝飾.... – 2012-02-29 13:43:23
