javascript - 为什么我的 CasperJS 代码无法登录 Quora？

Question

这是我用来登录 Quora 的代码:

var casper = require('casper').create({ 
    verbose: true, 
    logLevel: 'debug',
    pageSettings: {
         loadImages:  false,         // The WebPage instance used by Casper will
         loadPlugins: false,         // use these settings
         userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4'
    }
});

casper.start('http://www.quora.com', function()
    {
        this.echo("page loaded");
        this.test.assertExists('form.inline_login_form', 'form is found');
        this.fill('form.inline_login_form',{email:'XXXXX',password:'XXXXX'},true);

    }
);


casper.then(function(){
   this.echo("Page Title " + document.title);
});

casper.run();

这是我看到的输出:

我期待它登录并显示标题。类似“Home-Quora..”之类的东西为什么没有发生这种情况？

您是否正在尝试使用 Facebook 密码登录？如果是这样，则由于弹出窗口被阻止，因此通过 Facebook 登录会出现问题。
