mac 下安装 CASPERJS

安装

brew install casperjs
安装完成后使用
1. phantomjs –version
2. casperjs –version
查看安装的版本
因为 phantomjs 2.00对支持 casperjs 有问题
需要修改
/usr/local/homebrew/Cellar/casperjs/1.0.4/libexec/bin/bootstrap.js 增加一段代码

var system = require('system');
var argsdeprecated = system.args;
argsdeprecated.shift();
phantom.args = argsdeprecated;

实例代码，登陆人人

var casper = require('casper').create({   
    verbose: true,

casper.options.viewportSize = {width: 1680, height: 924};
casper.start('http://www.renren.com');
casper.waitForSelector("form#loginForm",
    function success() {
        this.test.assertExists("form input[name='email']");
        this.fill('form[id="loginForm"]',{
            'email':'your name'

});

casper.waitFor(function check() {
    return this.getCurrentUrl().indexOf("www.renren.com/***")>-1;
}, function then() {
    console.log("登录成功!!!!!!!!!!!!");
}).then(function(){
    console.log("执行登录后的其它操作!!!!!!!!!!!!");
    console.log("打开链接并截图");    
    this.capture("./renren.png");
