如何解决问题？
回答by Sunny Patel
json.loadtakes in a file pointer, and you're passing in a string. You probably meant to use json.loadswhich takes in a string as its first parameter.
json.load接收一个文件指针，然后传入一个字符串。您可能打算使用json.loadswhich 接受一个字符串作为其第一个参数。
Secondly, when you import json, you should take care to not overwrite it, unless it's completely intentional: json = json.load(teststr)<-- Bad.
This overrides the module that you have just imported, making any future calls to the module actually function calls to the dict that was created.
其次，当你import json，你应该注意不要覆盖它，除非它完全是故意的：json = json.load(teststr)<-- Bad。这将覆盖您刚刚导入的模块，使以后对该模块的任何调用实际上都是对创建的 dict 的函数调用。
To fix this, you can use another variable once loaded:
要解决此问题，您可以在加载后使用另一个变量：
import json
teststr = '{"user": { "user_id": 2131, "name": "John", "gender": 0, "thumb_url": "sd", "money": 23, "cash": 2, "material": 5}}'
json_obj = json.loads(teststr)
ORyou can change the module name you're importing
或者您可以更改要导入的模块名称
import json as JSON
teststr = '{"user": { "user_id": 2131, "name": "John", "gender": 0, "thumb_url": "sd", "money": 23, "cash": 2, "material": 5}}'
json = JSON.loads(teststr)
ORyou can specifically import which functions you want to use from the module
或者您可以专门从模块中导入要使用的功能
from json import loads
teststr = '{"user": { "user_id": 2131, "name": "John", "gender": 0, "thumb_url": "sd", "money": 23, "cash": 2, "material": 5}}'
json = loads(teststr)
