Question

我用下面的代码得到一个KeyError。我可以找到的其他解决方案无效。

我正在使用请求进行API调用。它返回以下JSON：

{"status":200,"msg":"OK","result":{"url":"https:\/\/redacted\/something","valid_until":"2019-10-13 12:34:56"}}

我只需要此JSON中的URL，但似乎无法正常工作。

#!/usr/bin/env python
import requests
import json

url = 'https://redacted'
user = 'redacted'
api_token = 'redacted'

r = requests.get(url)

r_dict = r.json()

print(r_dict['url'])

Answer 1

URL在result字典中。

print(r_dict['result']['url'])

Answer 2

我可以使用

解码您的JSON字符串

#!/usr/bin/python3

import json

json_in = '{"status":200,"msg":"OK","result":{"url":"https:\/\/example.com\/something","valid_until":"2019-10-13 12:34:56"}}'

json_stuff = json.loads(json_in)

# debugging only print(json_stuff.keys())
print(json_stuff['status'])
print(json_stuff['msg'])
print(json_stuff['result'])
print(json_stuff['result']['url'])
print(json_stuff['result']['valid_until'])

尝试提取JSON字符串时出现KeyError
