Unix中的Chrome Headless返回空页源

使用Chrome Headless在Unix机器(Cent OS)中运行我的selenium测试脚本。但是相同的脚本在我的本地Windows机器上完美运行。

但是在Unix机器上它返回空页面源,就像空的html标签一样。

虽然使用了最新的ChromeDriver 2.33和谷歌浏览器版本62.0,但不知道它出错了。

       System.setProperty("webdriver.chrome.driver", "/../chromedriver.exe");

        --chromedriver.exe for windows local machine
        -- chromedriver for unix machine

        ChromeOptions options = new ChromeOptions();
        options.addArguments("--headless");
        options.addArguments("--no-sandbox");
        options.setAcceptInsecureCerts(true);
        options.addArguments("--ignore-ssl-errors=true");
        options.addArguments("--ssl-protocol=any");
        options.setHeadless(true);

        driver = new ChromeDriver(options);

        System.out.println("Timeout invoke ");
        driver.get("https://www.google.co.in/");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        System.out.println("After invoke ");
        System.out.println("PAGE SOURCE : \n" + driver.getPageSource());
        System.out.println("RUN COMPLETE..");

在Unix机器上运行上面的内容我

要在Chrome Browser的{​​{1}}中投放Headless Mode,请添加参数 Unix Systems --disable-gpu

--remote-debugging-port=9222

注意A :避免将任何单个 WebDriver 实例同时传递System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe"); ChromeOptions options = new ChromeOptions(); options.addArguments("--headless"); options.addArguments("--no-sandbox"); options.setAcceptInsecureCerts(true); options.addArguments("--ignore-ssl-errors=true"); options.addArguments("--ssl-protocol=any"); options.setHeadless(true); options.addArguments("--remote-debugging-port=9222"); options.addArguments("window-size=1400,600"); WebDriver driver = new ChromeDriver(options); System.out.println("Timeout invoke "); driver.get("https://www.google.co.in/"); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); System.out.println("After invoke "); System.out.println("PAGE SOURCE : \n" + driver.getPageSource()); System.out.println("RUN COMPLETE.."); addArguments("--headless")选项。

注意B :避免在基于Linux / Unix的系统上使用setHeadless(true),因为它是基于Windows的操作系统的配置。

  

参考:Getting Started with Headless Chrome

更新

正如您所见:

addArguments("--disable-gpu");

按照以下步骤操作:

  • 通过WebDriverException: chrome not reachable
  • 卸载Chrome Browser
  • 运行Revo Uninstaller工具以清除所有操作系统。
  • 选择CCleaner
  • 安装当前版本的System Restart
  • 执行Chrome Browser

我有同样的问题。特别是在添加没有有效证书的代理时。这是对我有用的东西:(python代码)

    polipo_proxy = "127.0.0.1:8124"
    proxy = Proxy({
        'proxyType': ProxyType.MANUAL,
        'httpProxy': polipo_proxy,
        'ftpProxy' : polipo_proxy,
        'sslProxy' : polipo_proxy,
        'noProxy'  : ''
    })
    capabilities = dict(DesiredCapabilities.CHROME)
    proxy.add_to_capabilities(capabilities)
    capabilities['acceptSslCerts'] = True
    capabilities['acceptInsecureCerts'] = True

    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--ignore-certificate-errors')
    chrome_options.add_argument('--disable-gpu')
    chrome_options.add_argument('--window-size=1280,1000')
    chrome_options.add_argument('--allow-insecure-localhost')
    chrome_options.add_argument('--allow-running-insecure-content')
    chrome_options.add_argument('--no-sandbox')
    driver = webdriver.Chrome(executable_path=os.path.abspath("/var/chromedriver/chromedriver"), chrome_options=chrome_options, desired_capabilities=capabilities)

ssl证书的问题,我也有同样的问题。对于无头镀铬以下选项无效,请尝试达到其他非ssl链接。 chrome选项 - &gt; - 忽略SSL的错误

我有同样的问题。事实证明,在我的情况下,请求的页面返回了不成功的HTTP状态代码(在我的情况下为4xx),这在使用<html><head></head><body></body></html>时导致了getPageSource

在Unix上,您还需要引用Chrome二进制文件。

options.setChromeBinaryPath("/usr/bin/google-chrome");
