所以我正在从网站检索一些 JSON 数据并使用来自 urllib2 的标准 urlopen()：

代码：

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()

结果： 

{
   "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": [
                 ]
    }
}

这个结果是错误的。如果我在浏览器中手动输入网址：

输入：

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：

        }
      }                 ]
}

}

此外，当我使用 CURL 检索数据时，我得到：

         "not_voting": "0",
         "majority_position": "No"
        },
       "independent": {

        },
       "total": {
         "yes": "21",
         "no": "79",
         "present": "0",
         "not_voting": "0"
        }
      }                 ]
}

}

因此，对于同一个 Web 请求，这是 3 个不同的结果。这里有什么问题？是否有一些我忽略的缓存机制或者我错过了什么？

看起来您必须在请求中设置“Accept-Encoding”标头。

以防万一，您可以这样设置：

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