Firefox硒驱动程序无法加载任意 [英] Firefox Selenium Driver fails to load arbitarily

问题描述

我有这个代码来创建我的网络驱动程序。

现在这个代码工作正常，如果我创建驱动程序1的1.

在多个创建这些驱动程序时出现的问题线程。

  public static WebDriver getConfiguredWebDriver（.....）
 WebDriver driver = null; 
 DesiredCapabilities cap = new DesiredCapabilities（）; 
 if（ffp！= null）{
 ffp.setPreference（general.useragent.override，getRandomizedUASettings（rand，UserAgentList））; 
} 
 driver = new FirefoxDriver（null，ffp，cap）; 
 // driver = new FirefoxDriver（）;在多线程
 return driver中也给出了同样的错误; 
 
 
 
 $ b $ p 
 $ b $ p 
 
 
 
 
 
 
 
 
 
 
 
Thread-4org.openqa.selenium.WebDriverException：无法连接到端口7057上的二进制FirefoxBinary（C：\ Program Files（x86）\Mozilla Firefox\firefox.exe）;进程输出如下：
 null 
 Build info：version：'2.28.0'，revision：'18309'，time：'2012-12-11 20:21:45'
系统信息：os.name：'Windows 7'，os.arch：'amd64'，os.version：'6.1'，java.version：'1.6.0_26' 
 
 
线程代码是 
 
 
  while（...）{
 ....... // 
 FirefoxProfile ffp = new FirefoxProfile（）; 
 DataEntryThread t = new DataEntryThread（parentFrame，lead，new ProxySettings（proxySettings），ffp，UserAgentList）; 
 t.start（）; 
 ....... // 
} 
  
任何线程随机甚至端口号。这里有什么问题？如何在不同的线程上实现加载多个firefox驱动程序？
解决方案
上面代码的一部分 
 
 
  boolean driverCreated = false; 
 int retryCnt = 3; 
 int count = 0; （！driverCreated& count< retryCnt）{
 try {
 driver = new FirefoxDriver（null，ffp，cap）; 
 driverCreated = true; 
 System.out.println（Driver Created）; 
} catch（Exception e）{
 retryCnt ++; 
 
 
 if（driverCreated == false）{return null;基本上，我认为使用不同的线程加载驱动程序访问相同的Firefox二进制文件在同样的错误，但我仍然不确定。
 
I have this code for creating my web driver.

Now this code works fine if I create the driver 1 by 1.

The problem arises when creating these drivers on multiple threads.
public static WebDriver getConfiguredWebDriver(.....)
  WebDriver driver = null;
  DesiredCapabilities cap = new DesiredCapabilities();
  if(ffp != null) {
    ffp.setPreference("general.useragent.override", getRandomizedUASettings(rand, UserAgentList));
  }
  driver = new FirefoxDriver(null, ffp, cap);
  //driver = new FirefoxDriver(); also gives an error of the same kind during multithreading
  return driver;
}
It gives me this error

"Thread-4" org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files (x86)\Mozilla Firefox\firefox.exe) on port 7057; process output follows: 
null
Build info: version: '2.28.0', revision: '18309', time: '2012-12-11 20:21:45'
System info: os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.6.0_26'

The thread code is
while(...) {
  ....... //
  FirefoxProfile ffp = new FirefoxProfile();
  DataEntryThread t = new DataEntryThread(parentFrame, lead, new ProxySettings(proxySettings), ffp, UserAgentList);
  t.start();
  ....... //
}
The error comes on any thread randomly and even the port number. What is wrong here ? How do I achieve loading multiple firefox drivers on different threads ?
解决方案
I have found a work around for this.. just modify a part of the above code
boolean driverCreated = false;
int retryCnt = 3;
int count = 0;
while(!driverCreated && count < retryCnt) {
  try {
    driver = new FirefoxDriver(null, ffp, cap);
    driverCreated = true;
    System.out.println("Driver Created");
  } catch (Exception e) {
    retryCnt++;
  }
}
if(driverCreated == false) { return null; }
Basically, I think the driver being loaded using different threads is accessing the same binary file of firefox at the same time which gives an error but I am still unsure of it.
