<type 'str'>

如何转换为response对象，然后提取中间的目标值？

Answer 1

C'est JSON, transformez-le en :

import json

content = '...你那堆东西'
result = json.loads(content)

print result['msg']

Cela convertira la chaîne de format JSON que vous avez obtenue en un dictionnaire result, puis la traitera normalement.

Answer 2

Ce qui est renvoyé, ce sont des données json, qui peuvent être analysées directement à l'aide de la bibliothèque json de Python.
Je pense que l'exploration des données JSON est la plus agréable à traiter
Une grande partie des données JSON explorées récemment sont les données JSON générées par les requêtes ultérieures
