CasperJS and 'Unsafe JavaScript attempt to access frame with URL' error
提问by michaeluskov
I have simple page with javascript which validates email written in input:
我有一个带有 javascript 的简单页面，用于验证输入中编写的电子邮件：
email.html:
电子邮件.html：
<!DOCTYPE html>
<html>
<head>
<title>Email validation</title>
<script src="email.js"></script>
</head>
<body>
<span style="padding: 5px;">
<input type="text" id="email-input" placeholder="Email..."></input>
</span>
</body>
</html>
email.js:
电子邮件.js：
var checkEmail = function() {
var regexp = /BIG_REGEX/;
var email = document.getElementById('email-input').value;
if (email === '')
removeFrame();
else if (regexp.test(email))
drawFrame('green');
else
drawFrame('red');
};
var removeFrame = function() {
var input = document.getElementById('email-input');
input.parentNode.style.backgroundColor = input.parentNode.parentNode.style.backgroundColor;
};
var drawFrame = function(color) {
var input = document.getElementById('email-input');
input.parentNode.style.backgroundColor = color;
};
window.onload = function() {
document.getElementById('email-input').onkeyup = checkEmail;
};
I want to test validation functionality using CasperJS. Here is my test case:
我想使用 CasperJS 测试验证功能。这是我的测试用例：
test/validator.test.js:
测试/validator.test.js：
var fillEmail = function(browser, email) {
browser.sendKeys('#email-input', email, {reset: true});
};
var getValidation = function(browser) {
var color = browser.evaluate(function () {
return document.getElementById('email-input').parentNode.style.backgroundColor;
});
return color;
};
var validate = function(browser, email) {
fillEmail(browser, email);
return getValidation(browser);
};
casper.test.begin('Validation testing', function suite(test) {
casper.start('http://localhost:8000/email.html', function() {
test.assertEquals(validate(this, '[email protected]'), 'green', '[email protected]');
test.assertEquals(validate(this, 'vnbgfjbndkjnv'), 'red', 'vnbgfjbndkjnv');
}).run(function() {
test.done();
});
});
But when I run tests using casperjs test test/validator.test.js, there is always error after information about tests:
但是当我使用 运行测试时casperjs test test/validator.test.js，在有关测试的信息之后总是出现错误：
Unsafe JavaScript attempt to access frame with URL about:blank from frame with URL file:///C:/Users/home/AppData/Roaming/npm/node_modules/casperjs/bin/bootstrap.js. Domains, protocols and ports must match.
Unsafe JavaScript attempt to access frame with URL about:blank from frame with URL file:///C:/Users/home/AppData/Roaming/npm/node_modules/casperjs/bin/bootstrap.js. Domains, protocols and ports must match.
What's wrong?
怎么了？
PhantomJS version: 1.9.8
PhantomJS 版本：1.9.8

Recent PhantomJS (1.9.8) introduced this error message. It doesn't cause any real issue, other than confusing log lines when quiting PhantomJS.
最近的 PhantomJS (1.9.8) 引入了这个错误信息。除了退出 PhantomJS 时混淆日志行之外，它不会导致任何实际问题。
It is fixed in unreleased 1.9 branch: https://github.com/ariya/phantomjs/pull/12720
它已在未发布的 1.9 分支中修复：https: //github.com/ariya/phantomjs/pull/12720

This issue is fixed in phantomjs version 1.9
此问题已在 phantomjs 1.9 版中修复
"phantomjs": "^1.9.9"
”phantomjs": "^1.9.9"
for casperJs
对于 casperJs
casperjs --ssl-protocol=tlsv1 test run.js

I was getting this same error, so I tried updating to phantomjs 1.9.9(from 1.9.8). However, I was getting an install error when trying to install 1.9.9, so I down rev-ed to phantomjs 1.9.7, and that fixed this error for me. So, it seems like this is an issue introduced in phantomjs 1.9.8.
我遇到了同样的错误，所以我尝试更新到phantomjs 1.9.9（从1.9.8）。但是，我在尝试安装时遇到了安装错误1.9.9，所以我降级为phantomjs 1.9.7，并为我修复了这个错误。因此，这似乎是phantomjs 1.9.8.

Hey there are several workarounds to try and get around this by exiting phantom in a different way such as
嘿，有几种解决方法可以尝试通过以不同的方式退出幻像来解决这个问题，例如
casperjs --ssl-protocol=tlsv1 test run.js
WHICH DOSE NOT HELP and
这没有帮助和
setTimeout(function(){
phantom.exit();
}, 0);
instead of
代替
this.exit();
Nothing has worked!!!
什么都没用！！！
I tried several different versions of PhantomJS. My output comes in as JSON and after many hours of failed attempts of JSON.parse(stdout)I had to give up. I figured 'F' it I'm just going to handle the 'F'ing error.
我尝试了几个不同版本的 PhantomJS。我的输出是 JSON，经过数小时的 JSON.parse(stdout) 失败尝试后，我不得不放弃。我想 'F' 它我只是要处理 'F'ing 错误。
so simple before i exit i
在我退出之前如此简单
this.echo(',{"error":"');
and After I send
在我发送之后
this.echo('"}]');
When i get my results back i simply replace all the line breaks and ignore the error
当我得到我的结果时，我只需替换所有换行符并忽略错误
stdout = stdout.replace(/(?:\r\n|\r|\n)/g, '');
Side note: this problem was tried to be fixed with phantom 1.9.9 but instead the focussed on building phantom 2.0 which is not compatible with CasperJS
旁注：这个问题试图用 phantom 1.9.9 修复，但重点是构建与 CasperJS 不兼容的 phantom 2.0
