尝试：

import json
j = json.loads('{"token":"eyJhbGciOiJIIkpXVCJ9.eyJpc3MiOiIxOWQzODdmZC1kMjA2LTQzNDYtOGRhNy1lMjRkNDZlMWZjZDgiLCJleHAiOjE0OTMwNTA1MxNH0.JBiPb0x4pg_lQXxEV-rbd27qvgm9Q","refresh_token":"639d4-b4e0-4c-8645-229b9e73a394","expires_in":604800,"user":{"id":"19d-d206-43-8da7-e2cd8","username":"tej123","email":"mrtej@gmail.com","enabled":true,"updated_email":null,"last_login_at":"2017-04-17T16:14:26.520Z"}}')
print(j['token'])
