问题描述

尝试通过REST GET方法按HTML页面访问列表项时出现以下错误（我没有在线运行SharePoint页面）。在一段时间之前工作正常，但现在给出以下错误。当把html放在CEWP中它可以工作正常但
当在浏览器中单独运行页面时它会给出以下错误。

I am getting below error when try to access a list item by HTML page by REST GET method  ( I have not running the page from SharePoint online). which work fine before some time but now giving below error. When put the html in a CEWP it work fine but when run the page separately in browser it gives below error.

对预检请求的响应未通过访问控制检查：请求的资源上不存在"Access-Control-Allow-Origin"标头。因此不允许原点'null'访问。响应的HTTP状态代码为403

谢谢和问候
