错误信息

XMLHttpRequest cannot load https://api.sms.jpush.cn/v1/codes. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access. The response had HTTP status code 400.
