如何从 python API 中的 urllib 结果中过滤数据

Question

这是我的代码：

    req = urllib.request.Request(url, headers=hdr)
    req.get_method = lambda: 'GET'
    response = urllib.request.urlopen(req)
    ### Response: 200 OK
    print("If Response=200 Script run is OK : " , response.getcode())
    print(response.read())

结果是：

如果 Response=200 脚本运行正常：200

如何在 output 中仅过滤和显示“accessToken” ？

Answer 1

很简单：

resp: bytes = b'[{"id":"d85b3704-60c9-XXXXXXX-2886629c732e","name":"XXXXXX-d85b37","location":"Trial","accountType":"Trial","url":"/www.ai/","accessToken":"eyJhbGciOiJodHRwOi8vd3d3LnczLm9yZy8yMDAxLzA0L3htbGRzaWctbW9yZSNobWFjLXNoYTI1NiIsInR5cCI6IkpXVCJ9.eyJBY2NvdW50SWQiOiJkODViMzcwNC02MGM5LTQ3NGYtYWVjYy0yODg2NjI5YzczMmUiLCJQZXJtaXNzaW9uIjoiQ29udHJpYnV0b3IiLCJFeHRlcm5hbFVzZXJJZCI6IjExNjAyMDI3NDYxNTkyMzc5NTU5MCIsIlVzZXJUeXBlIjoiR29vZ2xlIiwiSXNzdWVyTG9jYXRpb24iOiJUcmlhbCIsIm5iZiI6MTY2MzUzMzA4OSwiZXhwIjoxNjYzNTM2OTg5LCJpc3MiOiJodHRwczovL2FwaS52aWRlb2luZGV4ZXIuYWkvIiwiYXVkIjoiaHR0cHM6Ly9hcGkudmlkZW9pbmRleGVyLmFpLyJ9.VDoLlEdExAB0xMBP_pB6oN2DBL-9BQS0vEhpAq8d2o0","moveToArmStartedDate":"0001-01-01T00:00:00"}]'
import json


data = json.loads(resp)
print(data[0]['accessToken'])

好的，这现在如何工作？ 我们首先将响应加载到字典中。 然后我们简单地获取列表的第一个元素（因为您的响应是一个列表，idk 为什么）并使用 [' acessToken ['accessToken'] 。
