查了一些谷歌浏览器插件开发文档和资料,简单搞了个随机跳转插件,伪造网站来路地址。

//manifest.json
{
  "manifest_version": 2,

  "name": "随机跳转",
  "description": "Author zkx",
  "version": "1.0",

  "icons": {
    "128" : "icon.png"
  },
  "permissions": [
    "tabs", "http://*/*","https://*/*"
  ],
  "background": {
    "scripts": ["z.js"],
    "persistent": false
  },
  "browser_action": {
    "default_title": "随机跳转"
  },
  "manifest_version": 2
}
//z.js
chrome.browserAction.onClicked.addListener(function(tab) {
  // No tabs or host permissions needed!
  console.log('Turning ' + tab.url + ' 随机跳转');
  chrome.tabs.executeScript(null, {file: "x.js"});
});
//x.js

//指定跳转
document.writeln("<script>window.location.href=\'http://www.abc.com\';</script>");

//随机跳转
document.writeln("<script language=\'javascript\'>");
document.writeln("setTimeout(function(){");
document.writeln(" var arr=[\'http://www.dlshoushengqi.com/?id=1\',\'http://www.dlshoushengqi.com/?id=2\',\'http://www.dlshoushengqi.com/?id=3\'];");
document.writeln("    window.location.href=arr[parseInt(Math.random()*arr.length)];");
document.writeln(" },5000);");
document.writeln("</script>");
