TypeError:JSON对象必须是str,而不是'dict'

Question

对不起伙计们,我找不到令人满意的答案来打印部分json回复.有人可以帮助我吗:

import json
import requests
import pprint 

response = requests.get('<api endpoing>')
json_data = response.json()
print(json.dumps(json_data, indent=4, sort_keys=True))

Json的回应是

{
    "Value1": "SomeValue",
    "data": {
        "subval1": false,
        "subval2": "0a4",
        "subval3": "",
        "subval4": "Click h!",
        "subval5": "1002",
        "subval6": "932",
        "subval7": "i2",
        "subval8": 250,
        "subval9": 0,
        "subval10": 1,
        "subval11": 3,
        "subval12": 1,
        "subval13": "<!>",
        "subval14": "",
        "subval15": "Click !!",
        "subval16": "",
        "subval17": 300
    },
    "error": true,
    "message": "Success",
    "status": 200
}

现在,我想遍历并打印"数据":值.我会做以下事情

data = json.loads(json_data)
data_set = (data['data'])
print(data_set)

但我得到的错误:TypeError:JSON对象必须是str,而不是'dict'

你不需要json.loads(json_data)因为它已经是一个python dict,你只需要直接输出这个dict.从dict输出json字符串就是这样json.dumps()的工作:

json.dumps(json_data["data"])
