通過twitter搜索json響應輸出json的瓶子路由

Question

我使用python庫python-twitter來訪問twitter api。

我正在做一個搜索查詢，並希望響應去我的燒瓶路線。

我得到這個埃羅

TypeError: <twitter.status.Status object at 0x7f16dc089110> is not JSON serializable 

這裏是我有什麼

@app.route('/t/search/tweets', methods=['GET']) 
def twit(): 
    results = twitter_api.GetSearch(count=count, term='hello world') 
    return Response(json.dumps(results), mimetype='application/json') 

這裏是整個引用

Answer 1

我只好掏自己的源代碼，它原來必須使用AsDict()

json_results = [result.AsDict() for result in results] 

這樣的痛苦......

我使用tweepy而不是此lib中牢牢推薦缺少文件。

Answer 2

很明顯，python-twitter已經將api調用結果反序列化爲一個自定義的twitter.status.Status對象（或其列表）。默認情況下，json.dump()知道只有基本類型（字符串，數字，列表和類型的字典），所以你必須提供其他的事你自己的編碼器，如這裏說明：https://docs.python.org/2/library/json.html#encoders-and-decoders
