访问本地图片报跨域怎么回事？

Question

Access to image at 'file:///C:/Users/1/Desktop/%E6%B0%B4%E6%B3%A2%E7%BA%B9/img/bg2.jpg' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https.
换成线上的也不行 应该怎么办？

body {
    color: #fff;
    font-size: 16px;
    font-family: "Helvetica Neue",Helvetica,Arial,sans-serif;
    background-image: url(img/bg2.jpg);
    background-size: cover;
    background-position: 50% 0;
    height: 100%;
    text-align: center;
}

本地启sever，用localhost方式访问你网页就正常了。
