Question

我是Casper JS的新手，我遇到了fill()方法登录网站的问题。在调试输出中，我到达登录页面的URL，该登录页面应该在我登录后到达。然而，它然后将我发送到一个空白页并打破：

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

我已经测试了下面的代码登录到Facebook并且它有效。我还使用下面的Casperjs代码的Phantomjs版本成功登录到以下示例中的站点。所以这个问题似乎特定于使用Casperjs fill（）方法登录。

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）：

感谢任何帮助。谢谢！

尝试以下方法：

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() {
   ...
}

CasperJS无法使用fill（）方法登录
