捲曲的urlopen給出相互矛盾的結果

所以我檢索從一個網站的一些JSON數據，並使用標準的urlopen（）從urllib2的：捲曲的urlopen給出相互矛盾的結果

代碼：

url = 'http://api.nytimes.com/svc/politics/v3/us/legislative/congress/senate/votes/2011-12-14/2011-12-14.json?api-key=%s' % (api_key,) 
print urlopen(url).read()

結果：

{ 
    "status":"OK", 
    "copyright":"Copyright (c) 2011 The New York Times Company. All Rights Reserved.", 
    "results": { 
     "chamber": "Senate", 
     "start_date": "2011-12-14", 
     "end_date": "2011-12-14", 
     "num_results": "0", 
     "votes": [ 
       ] 
    } 
}

這個結果是錯誤的。如果我手動輸入網址進入我的瀏覽器：

請輸入：

http://api.nytimes.com/svc/politics/v3/us/legislative/congress/senate/votes/2011-12-14/2011-12-14.json?api-key=a55a8988c8102a532221d2d465ca010a:1:65328279

我得到：

    "status":"OK", 
    "copyright":"Copyright (c) 2011 The New York Times Company. All Rights Reserved.", 
    "results": { 
     "chamber": "Senate",

     "present": "0", 
     "not_voting": "0" 
     } 
     }     ] 
}

}

此外，當我使用curl檢索數據，我得到：

     "total": {

     "no": "79", 
     "present": "0", 
     "not_voting": "0" 
     } 
     }     ] 
}

}

因此，對於相同的Web請求，這有3種不同的結果。這裏有什麼問題？是否有一些我忽略的緩存機制，或者我錯過了什麼？

是否改變用戶代理的urlopen幫助。 – soulcheck 2011-12-14 18:30:21

使用小提琴手，並檢查有什麼不同的請求.... – 2011-12-14 18:32:27

看起來您必須在請求中設置「接受編碼」標頭。

以防萬一，你可以這樣設置：

request = urllib2.Request(your_url) 
request.add_header('Accept-Encoding',whatever_in_this_case) 
opener = urllib2.build_opener() 
print opener.open(request).read()
