json作为SSIS中的数据源

Question

我正在尝试从openweathermap.org api反序列化json提要。经过大量的尝试，使用脚本转换任务，我得到的是错误，甚至是不同的错误。基于JSON生成的以下类，我应该如何为每个语句编写（因为类Weather和Main是类RootObject的一部分）？ 我甚至可以从api获取XML数据，而不是JSON。实施这个过程会更容易吗？ 我不是要求答案，只是一个开始的推动。

JSON ：

{  
   "coord":{  
      "lon":-122.08,
      "lat":37.39
   },
   "weather":[  
      {  
         "id":741,
         "main":"Fog",
         "description":"fog",
         "icon":"50n"
      }
   ],
   "base":"stations",
   "main":{  
      "temp":286.14,
      "pressure":1022,
      "humidity":82,
      "temp_min":285.15,
      "temp_max":287.15
   },
   "visibility":16093,
   "wind":{  
      "speed":1.11,
      "deg":13.5055
   },
   "clouds":{  
      "all":1
   },
   "dt":1479110160,
   "sys":{  
      "type":1,
      "id":397,
      "message":0.1452,
      "country":"US",
      "sunrise":1479134859,
      "sunset":1479171466
   },
   "id":5375480,
   "name":"Mountain View",
   "cod":200
}
