使用 PhantomJS + Selenium 处理重定向

Question

我目前运行在 Python 中通过 PhantomJS + Selenium 进行浏览器测试。

desired_capabilities = dict(DesiredCapabilities.PHANTOMJS)
desired_capabilities["phantomjs.page.settings.userAgent"] = ("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36")
driver = webdriver.PhantomJS(executable_path="./phantomjs", desired_capabilities=desired_capabilities)
driver.get('http://google.com')

这工作正常，除非我尝试 get 的页面上有重定向。

示例：

https://login.vrealizeair.vmware.com/

在这种情况下，get 无法正常工作。页面源为空：<html><head></head></body></html>.

这是一个 known issue 发布的解决方案，涉及添加一段代码以适当地处理重定向。

How/where 如果您运行使用 Selenium 进行测试（在我的第一个代码片段中），您是否添加此代码？它是 desired_capabilties 的一部分吗？

示例：

page.onNavigationRequested = function(url, type, willNavigate, main) {
    if (main && url!=myurl) {
        myurl = url;
        console.log("redirect caught")
        page.close()
        renderPage(url);
    }
};

page.open(url, function(status) {
    if (status==="success") {
    console.log(myurl);
        console.log("success")
            page.render('yourscreenshot.png');
            phantom.exit(0);
    } else {
        console.log("failed")
            phantom.exit(1);
    }
});

我用 PhantomJS 1.9.8 和 2.0.1-development 试过了。

Answer 1

我使用了以下设置：

DesiredCapabilities capabilities;
capabilities = new DesiredCapabilities();       
capabilities.setJavascriptEnabled(true);
capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "drivers/phantomjs.exe");
capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_PAGE_SETTINGS_PREFIX,"Y");
capabilities.setCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:16.0) Gecko/20121026 Firefox/16.0");

//intialize driver and set capabilties

driver = new PhantomJSDriver(capabilities);

然后，我执行了以下两行，它们对我来说工作得很好

driver.get("https://login.vrealizeair.vmware.com/");
System.out.println(driver.getCurrentUrl());
System.out.println(driver.getPageSource());

这是输出：

https://login.vrealizeair.vmware.com/sso/UI/Login
<!-- [RESPONSE_PAGE_TYPE=3DLOGIN] --><!DOCTYPE html><html><head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>Login | vRealize™ Air™</title>
    <link rel="stylesheet" href="/sso/css/styles.css?v=3" type="text/css">
    <link rel="shortcut icon" href="/sso/images/vmwareFavicon.ico" type="image/x-icon">

    <script async="" src="//rum-static.pingdom.net/prum.min.js"></script><script>...........................................
.....................................................
...................................................//Entire page source was displayed

我在 python 中尝试了以下代码，它似乎工作正常：

from selenium import webdriver

driver = webdriver.PhantomJS("./phantomjs") 

driver.get("https://login.vrealizeair.vmware.com/")
print 'done'
print driver.current_url
print driver.page_source

输出（工作正常）：

https://login.vrealizeair.vmware.com/sso/UI/Login
<!-- [RESPONSE_PAGE_TYPE=3DLOGIN] --><!DOCTYPE html><html><head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title>Login | vRealize™ Air™</title>
        <link rel="stylesheet" href="/sso/css/styles.css?v=3" type="text/css">

Imp note: 从基本页面开始导航。 html 代码为空，因为网站可能抛出 403 错误。如果登录 URL 不适合您，请尝试从出现在登录页面之前的页面导航。

Answer 2

原来是由于错误无法抓取页面：SSL handshake failed。

解决方案是使用以下行来初始化驱动程序：

driver = webdriver.PhantomJS(executable_path="./phantomjs", service_args=['--ignore-ssl-errors=true'])

Answer 3

这个解决方案对我来说真的很有效，我在 phantomjsdriver.log 中遇到了以下错误，并且在尝试登录时，phantomjs 正在注销。

[DEBUG - 2017-08-19T20:37:59.288Z] Session [47739640-851e-11e7-9326-9bef0ad085f5] - page.onResourceError - {"errorCode":299,"errorString":"Error transferring https://int-test-cc.gcsip.nl:4443/rest/user/keepAlive?cacheBuster=1503175078533 - server replied: Unsupported Media Type","id":9,"status":415,"statusText":"Unsupported Media Type","url":"IPAdd:port/rest/user/keepAlive?cacheBuster=1503175078533"}

在将以下功能添加到 phantomjs 后它起作用了 -

caps.setJavascriptEnabled(true)
caps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "phantomjs")
caps.setCapability(PhantomJSDriverService.PHANTOMJS_PAGE_SETTINGS_PREFIX,"Y");
caps.setCapability("phantomjs.page.settings.userAgent","Mozilla/5.0 (X11; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0")//"Mozilla/5.0 (Unknown; Linux x86_64) AppleWebKit/602.1 (KHTML, like Gecko) PhantomJS/2.5.0-development Version/9.0 Safari/602.1")
caps.setCapability(PhantomJSDriverService.PHANTOMJS_PAGE_CUSTOMHEADERS_PREFIX + "Content-Type","application/json;charset=utf-8")
caps.setCapability(PhantomJSDriverService.PHANTOMJS_PAGE_CUSTOMHEADERS_PREFIX + "Connection","Keep-Alive")
