Question

我需要将json中的以下嵌套字典从api复制到csv文件

{
 "result": [{
               "short_description": "I am getting bluescreen error",
               "sys_id": "39b5f8c2376ede007520021a54990e5c",
               "opened_at": "2016-04-04 05:19:53",
               "number":"INC0258523"
             },
             {
               "short_description": "laptop crashed with a blue screen",
               "sys_id": "da0095380f43d200a4f941fce1050eeb",
               "opened_at":"2016-04-25 06:33:52",
               "number":"INC0259067"
             }, 
             {
               "short_description": "Laptop not booting",
               "sys_id": "ecf9c9b00f43d200a4f941fce1050e17",
               "opened_at": "2016-04-25 06:07:16",
               "number": "INC0259061"
             }]
}

这是我到目前为止所尝试的

  with open('D:/file.csv', 'wb') as f:  
        w = csv.DictWriter(f, data.keys())   
        w.writerow(data)

我在csv文件的单个单元格中得到以下结果

[{"short_description":"I am getting bluescreen error","sys_id":"39b5f8c2376ede007520021a54990e5c","opened_at":"2016-04-04 05:19:53","number":"INC0258523"},{"short_description":"laptop crashed with a blue screen","sys_id":"da0095380f43d200a4f941fce1050eeb","opened_at":"2016-04-25 06:33:52","number":"INC0259067"},{"short_description":"Laptop not booting","sys_id":"ecf9c9b00f43d200a4f941fce1050e17","opened_at":"2016-04-25 06:07:16","number":"INC0259061"}]}

我需要它的格式是密钥short_description，sys_id，opened_at，number是列名，它们的值是相应的列数据。

您需要提取行词典。现在，您正在使用顶级'result' dict来提供csv编写器。

  with open('D:/file.csv', 'wb') as f:  
        w = csv.DictWriter(f, data['result'][0].keys())   
        for row in data['result']:
            w.writerow(row)
