服务端Python写的，请求api.weixin.qq.com的时候，时不时的会报错，无法连接：

Python代码如下：

    # 微信登陆
    openid_url = "https://api.weixin.qq.com/sns/jscode2session?appid=%s&secret=%s&js_code=%s&grant_type=authorization_code" % (
        settings.MINIAPP_SETTING.get(apiuser.app_id), settings.MINIAPP_SETTING.get(apiuser.app_key), code
    )
    req = requests.get(openid_url,verify=False)

错误1：
