Python无法访问字典 [英] Python Can't access dictionary

问题描述

在尝试使用python访问字典时获取TypeError: string indices must be integers.我试过使用json.loads(r2)产生了"TypeError: the JSON object must be str, bytes or bytearray, not dict"

Getting TypeError: string indices must be integers when trying to access a dictionary in python. I've tried using json.loads(r2) thos produces "TypeError: the JSON object must be str, bytes or bytearray, not dict"

即使不确定Im是否在正确的轨道上，我所需要做的就是将看起来像一个长字符串的JSON转换为x['SomeKey']之类的东西，并使用iteritems()或类似方式将这些键处的值显示出来?

Not even sure if Im on the right track here, all I need to do is get the JSON which appears to be in one long string into something like x['SomeKey'] and the value at those keys using iteritems() or similar?

r = requests.get(url, headers=headers)
r2 = r.json()
seq = json.dumps(r2)
print(seq['remotecontrol_id'])

推荐答案

r.json()已经返回了字典，所以我不确定为什么将r2传递给json.dumps并返回字符串(因此s ).您收到的错误消息甚至表明("TypeError:JSON对象必须是str，字节或字节数组，而不是 dict ")

r.json() already returns a dictionary so I'm not sure why you pass r2 to json.dumps that returns a string (hence the s). The error message you received even suggests that ("TypeError: the JSON object must be str, bytes or bytearray, not dict")

您的代码应为

r = requests.get(url, headers=headers)
r2 = r.json()
print(r2['remotecontrol_id'])
