标签: headless

我正在尝试在我的Linux机器(Slackware)上安装Java应用程序.

我收到了以下错误,我不明白.

你能告诉我如何处理这个问题吗？谢谢.

这是我得到的:(我看到需要设置一些X11 DISPLAY变量,但我应该给它什么值以及如何？)

~$ java -jar gate-5.0-beta1-build3048-installer.jar

在阅读QTKit应用程序编程指南时,我遇到了"无头环境"一词 - 这是什么意思？这是段落:

...包括具有GUI的应用程序和旨在"无头"环境中运行的工具.例如,您可以使用该框架编写操作QuickTime影片文件的命令行工具.

我在http://peter.sh/experiments/chromium-command-line-switches/#chrome-frame上仔细修改了交换机列表,我找不到任何可以在隐藏的后台进程中启动Chrome的内容.

我最接近的是--keep-alive-for-test+自定义打包应用程序,但应用程序无法执行任何传递的代码,因为(它报告的方式)"没有窗口 - ChromeHidden".

以下是我的代码:

case BrowserType.PhantomJS:
               var service = PhantomJSDriverService.CreateDefaultService(Path.Combine(_rootPath, @"Packages\"));
               var cookieFilePath=Path.Combine(_rootPath, @"Packages\cookie.txt");
                 if (!File.Exists(cookieFilePath))
                       File.Create(cookieFilePath);

                 var phantomjsoptions = new PhantomJSOptions();
                 driver = new PhantomJSDriver(service,phantomjsoptions);
                 var cookieJar = driver.Manage().Cookies;
                 driver.Navigate().GoToUrl(SeleniumConfiguration.Current.BaseURL);
                 cookieJar.AddCookie(new Cookie("x", "12345"));
                 return driver;

基本上问题是我无法登录我的测试应用程序因为我收到错误说 -

"您的浏览器设置为阻止Cookie"

我已经尝试了一切,但我似乎无法得到解决方案.
我该怎么办？
请帮帮我.
如果遗漏了一些细节,请告诉我.

尝试--headless使用Selenium webdriver命令在chrome上设置浏览器大小.

我得到这个webdriver错误:

Chrome Headless太棒了!

但有没有办法可以使用NPM安装Chrome Headless,以便我可以将它用于自动测试环境中的单元测试？

有没有其他方法可以做到这一点？

提前谢谢了!!!

我需要在无头ubuntu(Ubuntu 12.04.2 LTS-64 Bit)中安装vagrant .Vagrant ver-v1.3.0和Virtual box-4.2.18.添加vagrant包装盒后,当我给出"vagrant up"命令时,我收到以下错误:

我正在尝试java.awt.headless=true在应用程序启动期间设置,但看起来我已经太晚了,非无头模式已经开始:

static {
    System.setProperty("java.awt.headless", "true");
    /* java.awt.GraphicsEnvironment.isHeadless() returns false */
}

除此之外还有另一种无头的方式-Djava.awt.headless=true吗？我不想在控制台上配置任何东西.

机器:Window10(64位).

我下载了最新的VirtualBox,Vagrant和初始化的CentOS 6.7 64位图像/网址.

以下在Git-Bash会话中成功运行.
1. vagrant box添加"centos67x64"" https://github.com/CommanderK5/packer-centos-template/releases/download/0.6.7/vagrant-centos-6.7.box "
2. vagrant init
3.更新了Vagrantfile(并转为vb.gui选项,即取消注释文件中的配置部分).

  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    vb.gui = true

    # Customize the amount of memory on the VM:
    vb.memory = "2048"
  end

之后,我尝试了以下命令,但我收到此错误消息.

$ vagrant up

我已经在我的无头服务器上设置了xvfb服务器,当我运行DISPLAY =:99 firefox时,我得到这个异常缺少RANDR扩展

他们中的许多人说要从xorg.conf文件中禁用一些xinerna,但是在我的情况下没有创建这个文件.

所以我正在寻找如何添加缺少的RANDR扩展.
