硒似乎工作，但然後得到超時錯誤？

$ java -jar selenium-server-standalone-2.0b3.jar

當我運行此腳本：硒似乎工作，但然後得到超時錯誤？

from selenium.webdriver.common.keys import Keys 
import time 

browser = webdriver.Remote('http://localhost:4444/wd/hub', {'browser_name':'firefox','platform':'ANY', 'version':'','javascript_enabled':True}) 
browser.get("http://www.yahoo.com")

硒服務器似乎在第一工作：

00:17:08.776 INFO - Executing: [new session: {platform=ANY, browser_name=firefox, javascript_enabled=true, version=}] at URL: /session)

但後來我得到一個蟒蛇錯誤：

    browser = webdriver.Remote('http://localhost:4444/wd/hub', {'browser_name':'firefox','platform':'ANY', 'version':'','javascript_enabled':True})

可能是因爲/ etc/hosts文件具有環回地址。您是否嘗試將值127.0.0.1更改爲正確的IP地址？ – 2011-06-01 04:44:32

外貌就像你使用Selenium Grid一樣。網格由一個集線器和連接到它的節點組成。當你運行一個測試時，你發送一個請求到服務器，根據你在desired_capabilities中定義的內容，相應地向主機發送相應的配置。在這種情況下，你似乎沒有在任何地方啓動節點。

您似乎無法啓動節點。另外我相信使用WebDriver需要Grid 2.0。據我瞭解，你使用的版本只有RC API的Grid支持。如果您下載並編譯當前中繼，則可以使用以下指南： http://code.google.com/p/selenium/wiki/Grid2

你是怎麼知道他在使用網格的？好奇地知道並學習:) – 2011-06-03 15:27:58

他的RemoteWebDriver連接到http：// localhost：4444/wd/hub，它應該是網格配置的中心。 – 2011-06-03 15:58:11
