我正在開發一些fb應用程序,使用python-sdk。 有時候,我得到一個「未捕獲異常」,看起來像:如何捕捉「未捕獲的異常」?
Uncaught exception GET… … … GraphAPIError: Error validating access token.
我知道這個異常的原因,以及如何解決這個問題(更新OAuth令牌)。
但我怎麼能抓住它?
傳統try: .. except:
不這樣做。
尋找一個解決方案,而不是黑客的SDK代碼。
完整的錯誤輸出,要求在註釋:

嘗試/除非代碼:
try:
graph = facebook.GraphAPI(access_token)
except:
assert False, 'cougth it'
你確定你沒有捕捉(併吞咽)在其他地方的例外嗎? – 2011-04-08 09:35:43
我不知道你是否可以在Python中做到這一點,但我會嘗試調試這與調試器設置爲停止何時何地拋出異常,並按照其路徑向上檢查堆棧。 – 2011-04-08 09:41:10
當然,我無法抓住它,腳本停止工作。我是Python新手,第一次遇到這種異常。我想我可以通過破解SDK代碼來解決它,但是我試圖避免它,如果可能的話。 – 2011-04-08 09:44:06
