【跨域】浏览器本地网络接入检查

2025年10月28日 chrome 142更新后，本来借助外网域名来访问内网服务的站点都不能访问了，报错如下：

Access to XMLHttpRequest at '' from origin '' has been blocked CORS policy: The request client is not secure context and resource is more-private address space 'local'.

or

 Access to script at '' from origin '' has been blocked by CORS policy: Permission was denied for this request to access the 'unknow' address space.

当chrome升级到142版本、Edge浏览器升级到143版本后，浏览器将“Local Network Access Checks”策略由默认“Disabled” 改为“Enabled”.

解决方案

chrome://flags/#local-network-access-check

 

edge://flags/#local-network-access-check
