1, 首先在ubuntu上面安裝tor

詳情可以參考 https://www.torproject.org/docs/debian.html.en

You need to add the following entry in /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/:

deb http://deb.torproject.org/torproject.org trusty main
deb-src http://deb.torproject.org/torproject.org trusty main

Then add the gpg key used to sign the packages by running the following commands at your command prompt:

gpg --keyserver keys.gnupg.net --recv 886DDD89
gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add -

You can install it with the following commands:

$ apt-get update
$ apt-get install tor deb.torproject.org-keyring

2, 利用casperjs訪問網站 https://whatismyipaddress.com/ 來測試自己現在的對外IP

建立一個js檔案，名為index.js。內容如下。

var document = [];
var casper = require('casper').create({
      verbose: false,
      logLevel: "info"
});

casper.on('remote.message', function(msg) {
    this.echo('remote message caught: ' + msg);
});

casper.start("https://whatismyipaddress.com/", function() {
      this.evaluate(function () {
          console.log('hello world');
          console.log('current ip is: '+document.querySelector('a[href^="//whatismyipaddress.com/ip/"]').textContent.trim());
      });
});

casper.run();
 

$ casperjs index.js

這是可以看到自己的ip地址。

4, 利用tor的代理來執行casperjs的指令碼，如下

$ casperjs --proxy=127.0.0.1:9050 --proxy-type=socks5 index.js

這樣就會看到此時顯示的地址和之前的地址不一樣了。
