最近项目上线后，遇到一个奇怪的问题，部分客户的电脑浏览器提示：“Access to image at 'xxx' from origin 'xxx' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space 'private'.”。看下了请求响应报文Access-Control-Allow-Origin: *，未限制请求域。后来发现这是浏览器对网络请求做了限制，多发生于Chrome94版本，解决方案如下：
打开chrome一个新的标签页，输入“chrome://flags/#block-insecure-private-network-requests”，跳转到设置界面，将Block insecure private network requests属性值改为disabled。
保存设置，重启浏览器，项目调试正常。
