javascript - 使用 CasperJS 登录 Intacct 进行抓取

Question

有人可以给我指一个例子来制作一个登录 Intacct 并呈现屏幕截图的 CasperJS/PhantomJS 脚本吗？

casper = require("casper").create({
    waitTimeout: 60000,
    viewportSize: {
        width: 1024,
        height: 768
    },
    verbose: true,
    logLevel: 'debug',
    pageSettings: {
         loadImages:  false,
         loadPlugins: false,
         userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X)'
    }
});

casper.start("https://www.intacct.com/ia/acct/login.phtml");

casper.then(function() {
    casper.fill('form[name="iamain"]', {
        '.company': 'company',
        '.login': 'username',
        '.passwd': 'password',
    }, true);
});

casper.then(function() {
    casper.capture("screen.png");
});

casper.run();

** 根据下面的建议更新了代码

它保存的图像与登录屏幕完全相同。

这是 cmd 屏幕中显示的内容(已更新):

问题是该网站尚未加载，并且不会显示登录页面。尝试将 casper.capture("screen.png"); 添加到另一个 casper.then() block 中，这将使 casper 在收到以下响应后捕获屏幕截图由您的操作触发的请求。可能有更好的方法来做到这一点，但这在很多情况下对我有用。
