我是 Casper JS 的新手，我fill()对登录网站的方法有疑问。在调试输出中，我到达了登录页面的 url，该网址应该在我登录后到达。但是，它然后将我发送到一个空白页面并中断：

[debug] [phantom] Navigation requested: url=about:blank, type=Other, lock=true, isMainFrame=false

我已经测试了下面的代码以登录 facebook 并且它有效。我还使用下面的 Casperjs 代码的 Phantomjs 版本成功登录到下面示例中的站点。所以这个问题似乎是特定于使用 Casperjs fill() 方法登录的。

1）这是html（出于安全目的，我将其设为匿名）：

//login form
<form id="***id_form***" class="loginBox" method="post" action="https://***login_link***/">

// input login
<input id="IDToken1" type="text" value="" name="IDToken1">

// input password
<input id="IDToken2" type="password" name="IDToken2">

2）这是我的 Casperjs 代码：

var start_url = 'https://***login_url***'

casper.start(start_url, function() {

    this.test.assertExists('form#***id_form***', 'form is found');
    this.fill('form#***id_form***', {
        'IDToken1': '***MY_ID***',
        'IDToken2': '***MY_PASSWORD***'
    }, true);
});

casper.run();

3）这是控制台输出（我隐藏了网址）：

尝试以下操作：

casper.start(start_url, function() {
    this.waitForSelector('form#***id_form***', function() {
        this.fill('form#***id_form***', {
            'IDToken1': '***MY_ID***',
            'IDToken2': '***MY_PASSWORD***'
        }, true);
    }
});

casper.then(function() {
   ...
}
