硒服务器，硒客户端，在 UBUNTU GUI 服务器上 [英] selenium server, selenium client, on an UBUNTU GUI server

问题描述

我有一个带有 ubuntu 14.04 LTS 的 VPS 并安装了桌面包，这意味着我可以从 ssh -X 启动 firefox会议.为了进行测试，我从我的服务器启动了 selenium 独立服务器 jar (selenium-server-standalone-3.0.0-beta3.jar)启动它后，在另一个 ssh 会话中，我只需输入 python 命令:

i have a VPS with ubuntu 14.04 LTS and with the desktop package installed, that mean I can launch firefox from a ssh -X session. To make tests, I launched from my server the selenium standalone server jar (selenium-server-standalone-3.0.0-beta3.jar) After launching it, in another ssh session, i just enter python commands :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

之后，按照来自http://selenium-python.readthedocs.io/getting-started.html#using-selenium-with-remote-webdriver，我输入:

And after that, following the instructions from http://selenium-python.readthedocs.io/getting-started.html#using-selenium-with-remote-webdriver, I enter :

driver = webdriver.Remote(
command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities=DesiredCapabilities.FIREFOX)

45 秒后，我在服务器窗口和客户端窗口中都有很多错误.这是主要错误:

After 45sec, i have lots of errors in both server window and client window. Here is the main error :

引起:org.openqa.selenium.firefox.NotConnectedException:45000 毫秒后无法在端口 7055 上连接到主机 127.0.0.1.火狐控制台输出:错误:GDK_BACKEND 与可用显示不匹配

Caused by: org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output: Error: GDK_BACKEND does not match available displays

我看到一些人有同样的问题，但即使使用最新的 java 和 selenium 版本，我仍然遇到这个问题.预先感谢您的帮助

I saw some people with the same problem, but even with the latest java and selenium versions, i still got this issue. Thank you in advance for your help

推荐答案

您似乎正在使用最新的 firefox 版本尝试 selenium 3.要使用 selenium 3 支持最新的 firefox，需要下载最新的 geckodriver从此链接可执行并将其解压缩到您系统中的任何位置.

It seems you're trying selenium 3 with latest firefox version. To support latest firefox with selenium 3, need to download latest geckodriver executable from this link and extract it into you system at any location.

现在运行 selenium-server-standalone-3.0.0-beta3.jar 使用下面的命令:-

Now to run selenium-server-standalone-3.0.0-beta3.jar use below command :-

java -jar selenium-server-standalone-3.0.0-beta3.jar -Dwebdriver.gecko.driver = "path/to/downloaded geckodriver"

现在您需要将 marionette 属性的功能设置为 true 以支持最新的带有 selenium 3 的 firefox，如下所示:-

Now you need to set capability with marionette property to true to support latest firefox with selenium 3 as below :-

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
caps["marionette"] = True

driver = webdriver.Remote(command_executor = 'http://127.0.0.1:4444/wd/hub', desired_capabilities = caps)
