postman返回信息如下：

具体的后端代码如下：
@app.route('/code2Session', methods=['get', 'post'])
def code2Session():
    # global js_code
    # print(js_code)
    # global touser
    data = {'secret': 'xxx','js_code': '073mFxll2UeXJ74VZIll26O4AA3mFxl0','grant_type': 'authorization_code','appid':'wxc811b0e21cd4d0a5'}
    url = 'https://api.weixin.qq.com/sns/jscode2session?appid=APPID&secret=SECRET&js_code=JSCODE&grant_type=authorization_code'
    SessionData = requests.get(url,params=data)
