Python請求 - 以JSON數據並在python中使用它

-3

我有一個如下所示的代碼，它是域上的JSON代碼。 {"userCount":64,"users":[{"id":"553","acid":"553","ac":"240","cs":"Le AlphaDelta","st":{"gr":false},"co":[26.93526727771073,-79.9251579421954,10667.999977505215,-163.9999997562341,-2.2288855660652414,2.4376547336953407e-7],"ve":[-0.000002161617968514662,-6.915441330619387e-7,0.000004838653476326726,0,-2.27708260122718e-10,0],"ti":1487455628374.1194,"aircraft":"240","callsign":"Le AlphaDelta","time":1487455628374.1194} 我想python指向這個，並從它採取的數據，如我想採取CS，AC等我怎麼去做這件事？Python請求 - 以JSON數據並在python中使用它

編輯：我想獲取數據，比如json文件中第一個人的id，因爲文件中會有多個用戶。所以我不能擁有我在這裏的數據。基本上，我想採取上面的數據，並把它放在python中，並分解它，所以在python id [1] =第一個用戶的ID。

歡迎堆棧溢出。請參閱[問]並提供[mcve]。 –

看一看https://docs.python.org/2.7/library/json.html。

import json 
j = json.loads('{"userCount":64,"users":[{"id":"553","acid":"553","ac":"240","cs":"Le AlphaDelta","st":{"gr":false},"co":[26.93526727771073,-79.9251579421954,10667.999977505215,-163.9999997562341,-2.2288855660652414,2.4376547336953407e-7],"ve":[-0.000002161617968514662,-6.915441330619387e-7,0.000004838653476326726,0,-2.27708260122718e-10,0],"ti":1487455628374.1194,"aircraft":"240","callsign":"Le AlphaDelta","time":1487455628374.1194}') 
print j['ac']

如果我想從ac中獲取數據而沒有id等，該怎麼辦？ –

你可以這樣做：'爲我在j ['用戶']：打印我['ac']'所有交流應該打印 – clue404

我得到這個錯誤'追蹤（最近呼叫最後）：文件「C：\ Users \ Kyle \ AppData \ Local \ Programs \ Python \ Python36 \ yah.py」，第4行， for i [j'users']： TypeError：'Response'object is not subscriptable' –

你的JSON文本似乎並沒有被很好地形成：

>>> import json 
>>> json.loads('{"userCount":64,"users":[{"id":"553","acid":"553","ac":"240","cs":"Le AlphaDelta","st":{"gr":false},"co":[26.93526727771073,-79.9251579421954,10667.999977505215,-163.9999997562341,-2.2288855660652414,2.4376547336953407e-7],"ve":[-0.000002161617968514662,-6.915441330619387e-7,0.000004838653476326726,0,-2.27708260122718e-10,0],"ti":1487455628374.1194,"aircraft":"240","callsign":"Le AlphaDelta","time":1487455628374.1194}') 

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/usr/lib/python3.5/json/__init__.py", line 319, in loads 
    return _default_decoder.decode(s) 
    File "/usr/lib/python3.5/json/decoder.py", line 339, in decode 
    obj, end = self.raw_decode(s, idx=_w(s, 0).end()) 
    File "/usr/lib/python3.5/json/decoder.py", line 355, in raw_decode 
    obj, end = self.scan_once(s, idx)

明白了：

>>> import json 
>>> j = json.loads('{"userCount":64,"users":[{"id":"553","acid":"553","ac":"240","cs":"Le AlphaDelta","st":{"gr":false},"co":[26.93526727771073,-79.9251579421954,10667.999977505215,-163.9999997562341,-2.2288855660652414,2.4376547336953407e-7],"ve":[-0.000002161617968514662,-6.915441330619387e-7,0.000004838653476326726,0,-2.27708260122718e-10,0],"ti":1487455628374.1194,"aircraft":"240","callsign":"Le AlphaDelta","time":1487455628374.1194}]}') 
>>> print j['users']

>>> print j['users'][0]['ac'] 
240 
>>> print j['users'][0]['cs']
