【问题描述】：

我正在尝试获取 fortnite-api 网站数据，并且只获取“表情”下列出的内容

r = requests.get('https://fortnite-api.com/v2/cosmetics/br', headers=headers)

rr = r.json()
for sub_dict in rr['data']:
    for image_sub_dict in sub_dict['type']:
      for j in image_sub_dict['value']:
          print(j)

这导致TypeError: string indices must be integers | Json data

【解决方案1】：

您没有正确解析数据。

for image_sub_dict in sub_dict['type']: 行将返回 'type' 字典的键，而不是值。相反，您可能只想查询 'type' 字典以获取 "emote" 的值。下面是获取所有表情的图标 url 的示例：

import requests

response = requests.get(
    'https://fortnite-api.com/v2/cosmetics/br', 
    headers={'Accept': 'application/json'},
).json()

for entry in response['data']:
    kind = entry['type']['value']
    if kind  == 'emote':
        name = entry['name']
        icon = entry['images']['icon']
        print(f"{name}: {icon}")

输出：

【解决方案2】：

您需要添加一些日志来查看哪个键是错误的。试试：

rr = r.json()
print(rr, type(rr))
for sub_dict in rr['data']:
    print(sub_dict, type(sub_dict))
    for image_sub_dict in sub_dict['type']:
      print(image_sub_dict, type(image_sub_dict))
      for j in image_sub_dict['value']:
          print(j)
