由于UnicodeDecodeError而无法获得JSON响应？

Question

当我尝试运行python core-backup.py文件时，我无法获得JSON响应：代码FB_SHORT_ACCESS_TOKEN和FB_LONG_ACCESS_TOKEN相同。

core-backup.py：

import os
from os.path import join
import requests


def refresh_short_token():
    """
    Refresh short access token
    """
    request_url = FB_URL + 'oauth/access_token'
    request_payload = {
        'grant_type': 'fb_exchange_token',
        'client_id': FB_APP_ID,
        'client_secret': FB_APP_SECRET,
        'fb_exchange_token': FB_SHORT_ACCESS_TOKEN
    }
    response = REQ_SESSION.get(request_url, params=request_payload).json()
    # dotenvfile = find_dotenv()
    # load_dotenv(dotenvfile)
    # dotenv.set_key(dotenvfile, "FB_LONG_ACCESS_TOKEN", response['access_token'])
    FB_LONG_ACCESS_TOKEN = response["access_token"]
    # PAYLOAD['access_token'] = dotenv.get_key(dotenvfile, "FB_LONG_ACCESS_TOKEN")
    PAYLOAD['access_token'] = FB_LONG_ACCESS_TOKEN

'''
TODO: refresh_long_token()
    A function to refresh the long term access token
    Current validity: 60 days
'''

def get_feed():
    """
    Fetch feed
    """
    request_url = FB_URL + LTTK_GROUP_ID + '/feed'
    response = REQ_SESSION.get(request_url, params=PAYLOAD)
    if response.status_code == 400:
        refresh_short_token()
    print(response.json())
    return response.json()

def main():
    """
    Fetch posts from a Facebook group and populate in database
    """
    get_feed()

if __name__ == "__main__":
    main()

运行core-backup.py后，我在windows7中收到UnicodeDecodeError 文件。如何解决这个问题。 有关更清晰的信息，请参见屏幕截图：

Answer 1

您的代码页似乎设置为cp437。尝试在运行python脚本之前在终端中输入以下行，将python输出设置为utf-8。

set PYTHONIOENCODING=UTF-8
python core-backup.py

Answer 2

尝试将响应编码更改为UTF-8：

response.encoding = 'UTF-8'
print(response.json())
