（3）在设置页面中，勾选【重定向】，单击【新增】按钮： 

（5）依此类推，对如下网址也依次进行设置：

ajax.googleapis.com          ===> ajax.lug.ustc.edu.cn
www.google.com/recaptcha     ===> recaptcha.net/recaptcha
themes.googleusercontent.com ===> google-themes.lug.ustc.edu.cn

（7）也可以【导入】我设置好的配置文件（以下代码另存为 gooreplacer.gson 后导入）：

{
  "createBy": "http://liujiacai.net/gooreplacer/",
  "version": "3.11.0",
  "createAt": "2020/2/26 下午7:10:53",
  "redirect-rules": [
    {
      "src": "www.google.com/recaptcha",
      "kind": "wildcard",
      "dst": "recaptcha.net/recaptcha",
      "enable": true
    },
    {
      "src": "ajax.googleapis.com",
      "kind": "wildcard",
      "dst": "ajax.lug.ustc.edu.cn",
      "enable": true
    },
    {
      "src": "themes.googleusercontent.com",
      "kind": "wildcard",
      "dst": "google-themes.lug.ustc.edu.cn",
      "enable": true
    }
  ],
  "cancel-rules": [],
