ActiveCollab REST API 使用 Python [已解决] 收到的嵌套 JSON 中的访问值

Question

我通过 REST-API 从 ActiveCollab 得到这个：

{
"time_records": [
        {
            "id": 122,
            "class": "TimeRecord",
            "url_path": "\/projects\/89\/time-records\/122",
            "is_trashed": false,
            "trashed_on": null,
            "trashed_by_id": 0,
            "billable_status": 1,
            "value": 1.0,
            "record_date": 1645847200,
            "summary": "example",
            "user_id": 12365,
            "user_name": "Fred Coal",
            "user_email": "fredc@example.com",
            "parent_type": "Project",
            "parent_id": 89,
            "created_on": 1628497959,
            "created_by_id": 17,
            "created_by_name": "Fred Coal",
            "created_by_email": "fredc@example.com",
            "updated_on": 1635784512,
            "updated_by_id": 17,
            "job_type_id": 1,
            "source": "unknown",
            "original_is_trashed": false
        },       
    ],
}

我想获取“值”的值。

但我不知道如何访问此属性。

我正在为此使用 Python。

import requests
import json
startdate = "2021-08-01"
enddate = "2021-08-31"
fromto = "?from="+startdate+"&to="+enddate
#-------------- 
def ac_rq(endpoint):
    token ='*'
    url = "https://*/api/v1/"+endpoint
    resp = dict(requests.get(url, headers={'X-Angie-AuthApiToken': token}))
    print(resp)
    return resp
#--------------
a = ac_rq('projects/129/time-records/filtered-by-date'+str(fromto))
b = json.loads(a.text)
for i in b:
    print(i['time_records'][0]['value'])

input("press enter to exit")

我收到这个错误：

类型错误：字符串索引必须是整数

Answer 1

正如@rdas 在评论中提到的，您可以通过以下方式访问“值”：response['time_records'][0]['value']

Answer 2

见下文（将 json 字符串加载到字典中并引用请求的条目）

import json
data = '''{
"time_records": [
        {
            "id": 122,
            "class": "TimeRecord",
            "url_path": "\/projects\/89\/time-records\/122",
            "is_trashed": false,
            "trashed_on": null,
            "trashed_by_id": 0,
            "billable_status": 1,
            "value": 1.0,
            "record_date": 1645847200,
            "summary": "example",
            "user_id": 12365,
            "user_name": "Fred Coal",
            "user_email": "fredc@example.com",
            "parent_type": "Project",
            "parent_id": 89,
            "created_on": 1628497959,
            "created_by_id": 17,
            "created_by_name": "Fred Coal",
            "created_by_email": "fredc@example.com",
            "updated_on": 1635784512,
            "updated_by_id": 17,
            "job_type_id": 1,
            "source": "unknown",
            "original_is_trashed": false
        }      
    ]
}'''

data = json.loads(data)
print(data['time_records'][0]['value'])

输出

1.0
