使用Python遍历JSON

Question

我有以下JSON对象，并希望对其进行迭代：

 {
    "odata.metadata": "https://aaa/_api/$metadata#TimesheetActualData",
    "value": [{
        "PROJ_UID": "39bf6bca-8939-4df6-aa81-8a6c3b23c979",

        "Billing_Hours_Flag": null,
        "Final_Amount": "0.00",
        "ProjectCode": null,
        "WORKDAY": 0
    }, {
        "PROJ_UID": "39bf6bca-8939-4df6-aa81-8a6c3b23c979",
        "TASK_UID": "48dae88e-59ec-e611-80d4-00155d002a1c",

        "Final_Amount": "0.00",
        "ProjectCode": null,
        "WORKDAY": 0
    }],
    "odata.nextLink": "https://aaaa/_api/TimesheetActualData?$skip=1000"
 }

但是以某种方式，该代码无法正常工作：

header={'content-type': 'application/json'}
response=requests.get(url,headers=header)
jjj=json.dumps(str(response.content))
d=json.loads(jjj)
print(d['values'])

Answer 1

您不需要显式传递response.content到json模块来解析它，因为requests具有执行此操作的功能：

d = response.json()

然后，您可以遍历其值：

for value in d['value']:
    ...

Answer 2

更改

jjj=json.dumps(str(response.content))
d=json.loads(jjj)

至

d = json.loads(response.text)

“内容”和“文本”有什么区别

r.text是unicode中响应的内容，r.content是字节中响应的内容
