【问题描述】：

在 POST 请求之后，我得到一个以字节为单位的响应，但我想获取我的 access_token、refresh_token 怎么可能。

payload = 'grant_type=authorization_code&code=' + self.response_code + '&redirect_uri=' + self.redirect_uri
        auth = self.client_id+':'+self.client_secret
        endcoded_u = base64.b64encode(auth.encode("ascii")).decode("ascii")
        response = requests.post(
            url='https://api.getbase.com/oauth2/token',
            headers={
                'Content-Type': 'application/x-www-form-urlencoded',
                'Authorization': 'Basic %s' % endcoded_u,
            },
            data=payload,
            verify=True
        )
b'{"access_token":"5716f50fead975aa81340757cadbb1a2154681d9750c53abe4672143c7d938c3","token_type":"bearer","expires_in":3600,"refresh_token":"365e14fbd4d0e6a25486bf11cea3ebe84dbf5f2485fd95443a579c04f75e5e6e","scope":"read write profile sync"}'

有什么帮助吗？

【问题讨论】：

你能粘贴代码吗？可能你没看懂
你从哪里得到这个字符串？ response ?如果是，那么response.json() 应该直接给你dict 然后你可以直接访问access_token
我不知道为什么人们会贬低我的问题:(

你可以试试：

import json

data = b'{"access_token":"5716f50fead975aa81340757cadbb1a2154681d9750c53abe4672143c7d938c3","token_type":"bearer","expires_in":3600,"refresh_token":"365e14fbd4d0e6a25486bf11cea3ebe84dbf5f2485fd95443a579c04f75e5e6e","scope":"read write profile sync"}'
data = json.loads(data.decode())

print(data.get("access_token"))
# '5716f50fead975aa81340757cadbb1a2154681d9750c53abe4672143c7d938c3'

做

import json
token_bytes=b'{"access_token":"5716f50fead975aa81340757cadbb1a2154681d9750c53abe4672143c7d938c3","token_type":"bearer","expires_in":3600,"refresh_token":"365e14fbd4d0e6a25486bf11cea3ebe84dbf5f2485fd95443a579c04f75e5e6e","scope":"read write profile sync"}'

token_byte_string=token_bytes.decode("utf-8") #decode bytes to string

response = json.loads(token_byte_string) # built a dict from above string

response["access_token"] # this is your access token
