我无法正确捕获我正在用Casperjs登录的网页。我得到一张简单地带有“未实现”H1标签的网页图片。这里是下面的脚本：错误代码：402当试图用Casperjs捕获网页时
var casper = require('casper').create({
pageSettings: {
loadImages: false,//The script is much faster when this field is set to false
loadPlugins: false,
userAgent: 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.157 Safari/537.36',
customHeaders:{
'Authorization':'Basic '+btoa('someusername:somepassword')
}
}
});
casper.on("resource.error", function(resourceError){
console.log('Unable to load resource (#' + resourceError.id + 'URL:' + resourceError.url + ')');
console.log('Error code: ' + resourceError.errorCode + '. Description: ' + resourceError.errorString);
});
//First step is to open SkySpark Login
casper.start().thenOpen("http://192.168.9.150:89/user/login", function() {
console.log("SkySpark website opened");
});
//Second step is to click to the Sign-in button
casper.then(function(){
this.evaluate(function(){
document.getElementById("nav-tools").children[0].click();
});
});
//Now we have to populate username and password, and submit the form
casper.then(function(){
console.log("Login using username and password");
this.evaluate(function(){
document.getElementById("username").value="someusername";
document.getElementById("password").value="somepassword";
document.getElementById("loginForm").submit();
});
});
//Wait to be redirected to the Home page, and then make a screenshot
casper.then(function(){
console.log("Make a screenshot and save it as SkySparkTens.png");
this.capture('SkySparkTens.png');
});
//prints HTML to the console
casper.then(function(){
this.wait(5000, function() {
console.log(this.getHTML());
});
});
casper.run();
这里是控制台响应，我回去：

这里是一个登录页面上出现，我试图访问该网站的形式。

userModLogin.localeLogin = 'Login';

userModLogin.autoFocusId = 'username';
window.onload = function() { userModLogin.init(false); }
</script>
</head>
<body>
<form id='loginForm' method='post' action='/user/login'>

的完整剧本，你使用基本身份验证或者你通过表单登录到该网站？ – Vaviloff
我相信它通过一种形式，但我不确定。我更新了我原来的帖子，以包含我尝试正确访问的登录页面中的表单。 – nuccio
