在Flutter网站中发生XMLHttpRequest错误时启用CORS [英] Enable CORS while an XMLHttpRequest error occurs in flutter web

问题描述

当我使用该函数将数据添加到数据库时，并且在服务器上添加了 Access-Control-Allow-Origin ，以便不会被CORS阻止，但是当我在浏览器控制台工具标签控制台中查看时仍会出错

when I will add data to the database using the function, and on the server I have added Access-Control-Allow-Origin so that it is not blocked by CORS, but still error when I looked in the browser console tools tab console

Access to XMLHttpRequest at 'https://int.goo.id/api/pg/sso.register' from origin 'http://127.0.0.1:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

如何停用CORS？

推荐答案

用于在我的服务器上启用cors并解决波动网络中的 XMLHttpRequest错误

For enabling cors on my server and to resolve XMLHttpRequest error in flutter web

我正在使用此在我的 .htaccess 文件中，用于仅允许访问某些域

I am using this in my .htaccess file for allowing access to certain domains only

 <ifModule mod_headers.c>
    SetEnvIf Origin "http(s)?://(localhost:25120|domain.com|domain2.com)$" AccessControlAllowOrigin=$0
    Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header always set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
 </ifModule>
