如何从这个python请求repsonse中获取某个项目

标签： python python-requests

我以json格式收到此回复，但是如果有人可以向我解释这将是多么感谢，我在理解如何获取我需要的特定物品方面遇到了很多麻烦。我试图进入“杀手”，然后进入“价值”。我尝试使用：

kills = data['data']['kills']['value']
print(kills)

但是那行不通。

来自编辑者的注意：我使用This cool online JSON Formatter & Validator来清理提供的JSON数据。我经常使用此工具，并强烈推荐它。

这是您的数据的精简版本，仅使用kills键及其每个value键：

{
   "data":{
      "segments":[
         {
            "stats":{
               "kills":{
                  "value":427,
               },
            }
         },
         {
            "stats":{
               "kills":{
                  "value":279,
               },
            }
         },
         {
            "stats":{
               "kills":{
                  "value":136,
               }
            }
         },
         {
            "stats":{
            }
         },
         {
            "stats":{
               "kills":{
                  "value":12,
               }
            }
         }
      ],
   }
}

请注意，segments键下方的列表中有五个“段”词典，但是其中只有四个包含kills键。您可以使用以下方法为这四个中的每一个地址value：

record['data']['segments'][0]['stats']['kills']['value']
record['data']['segments'][1]['stats']['kills']['value']
record['data']['segments'][2]['stats']['kills']['value']
record['data']['segments'][4]['stats']['kills']['value']

index == 3中的segments条目没有kills键，因此尽管有五个段，但只有四个kills/value值。这是支持所有这些的代码，以及运行此代码的结果：

data = """{
    "data":{
        "segments":[
           ...
}"""
       

record = json.loads(data)
print(record['data']['segments'][0]['stats']['kills']['value'])
print(record['data']['segments'][1]['stats']['kills']['value'])
print(record['data']['segments'][2]['stats']['kills']['value'])
try:
    print(record['data']['segments'][3]['stats']['kills']['value'])
except Exception:
    print("invalid reference")
print(record['data']['segments'][4]['stats']['kills']['value'])

结果：

427
279
136
invalid reference
12

请注意，尽管我显示了上面数据的修剪版本，但是我在提供的完整数据版本上运行了此代码，这确实是有效的JSON。

只是扩展@steve的答案

更多修剪版本，以实现更好的可视化

   "data":
   {          
      "segments":
      [
            {"stats":{"kills":{"value":427}}},
            {"stats":{"kills":{"value":279}}},
            {"stats":{"kills":{"value":136}}},
            {"stats":{"seasonWins":{"value":0}}},
            {"stats":{"kills":{"value":12}}},
      ],
      "availableSegments":
      [
         {"type":"legend", "attributes":{}, "metadata":{}}
      ],
      "expiryDate":"2020-09-30T03:10:32.6124204+00:00"
   }

让循环更好地理解

for segments in data['data']['segments']:
    if 'kills' in segments['stats']:      # condition when expected node is not present
        print(segments['stats']['kills'])
        print(segments['stats']['kills']['value'])

输出

{'value': 427}
427
{'value': 279}
279
{'value': 136}
136
{'value': 12}
12
