Question

我想获得selenium推出的浏览器的PID。有没有办法完成它？

Answer 1

使用Python API，非常简单：

from selenium import webdriver
browser = webdriver.Firefox()
print browser.binary.process.pid
# browser.binary.process is a Popen object...

如果你正在使用Chrome，那就更复杂了，你可以通过一个镀铬过程：

c = webdriver.Chrome()
c.service.process # is a Popen instance for the chromedriver process
import psutil
p = psutil.Process(c.service.process.pid)
print p.get_children(recursive=True)

Answer 2

如果您正在使用PhantomJS，那么您可以从进程Popen对象中获取PID：

from selenium import webdriver
browser = webdriver.PhantomJS()
print browser.service.process.pid

Answer 3

在Java中，如果您使用ChromeDriver，则可以找到驱动程序将使用的端口

port = chromeDriverService.getUrl().getPort();

然后，使用该端口，您可以通过运行命令

找到chromedriver进程ID

netstat -anp | grep LISTEN | grep [port] (on linux)

或

netstat -aon | findstr LISTENING | findstr [port] (on windows)

您可以通过使用chromedriver进程ID（chrome进程的父ID）来进一步查找chrome进程ID

ps -efj | grep google-chrome | grep [chromedriverprocessid] (on linux)

或

wmic process get processid,parentprocessid,executablepath | find \"chrome.exe\" |find \"chromeDriverProcessID\"

代码如下所示：

并在Windows上：

starting chromedriver on port 34231
running command netstat -aon | findstr LISTENING | findstr 34231
parse command response line:
TCP    127.0.0.1:34231        0.0.0.0:0              LISTENING       10692
detected chromedriver process id 10692
running command wmic process get "processid,parentprocessid,executablepath" | findstr "chrome.exe" | findstr "10692"
parse command response line:
C:\Program Files (x86)\Google\Chrome\Application\chrome.exe  10692 12264
detected chrome process id 12264

Answer 4

hwjp的解决方案对我而言不再有效，但是如果有人怀疑，ABM的解决方案也适用于其他浏览器，所以到目前为止，对于Firefox：

from selenium import webdriver
driver = webdriver.Firefox()
print(driver.service.process.pid)

由于声誉而无法发表评论，所以我将其作为单独的答案提交...

Answer 5

您可以使用Selenium客户端通过以下几种不同方式来检索python启动的浏览器进程的PID：

Firefox

使用以下解决方案访问capabilities对象，该对象将返回dictionary：

代码块：

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.binary_location = r'C:\Program Files\Firefox Nightly\firefox.exe'
driver = webdriver.Firefox(firefox_options=options, executable_path=r'C:\WebDrivers\geckodriver.exe')
my_dict = driver.capabilities
print("PID of the browser process is: " + str(my_dict['moz:processID']))

控制台输出：
```
PID of the browser process is: 14240
```
浏览器快照：

Chrome

使用psutil.process_iter()遍历整个过程，其中process.cmdline()包含 --test-type=webdriver ，如下所示：

代码块：

from selenium import webdriver
from contextlib import suppress
import psutil

driver = webdriver.Chrome(executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.com/')
for process in psutil.process_iter():
    if process.name() == 'chrome.exe' and '--test-type=webdriver' in process.cmdline():
    with suppress(psutil.NoSuchProcess):
        print(process.pid)

控制台输出：
```
1164
1724
4380
5748        
```

Answer 7

如果你正在使用java和selenium，你可以先找到JVM的PID，然后通过它的子进程，你可以得到chromedriver的PID，然后是chrome的chrome。这是一个找到chromedriver PID的例子。

forChild

Answer 8

我这样解决了：

我正在使用 Python 的 Linux操作系统来检测 Firefox 的内存使用情况：

import psutil

# Get pid of geckodriver
webdriver_pid = driver.service.process.pid

# Get the process of geckodriver
process = psutil.Process(webdriver_pid)

# Get memory of geckodriver + firefox
# Since memory is in bytes divide by 1024*1024 to obtain result in MB
total_memory = sum([x.memory_info().rss/1048576 for x in process.children() + [process]])

Answer 9

这是可用于C＃和Selenium的示例。其他语言（例如Java）也可以使用相同的实现，但是我只使用C＃。

Chrome允许您提供自己的用户定义的命令行参数。因此，您可以在当前正在运行的程序的PID（Windows进程ID）中添加一个名为“ scriptpid-”的参数。 ChromeDriver在命令行中将参数传递给Chrome。然后使用Windows WMI调用从正在运行的Chrome的命令行中检索此PID ...

public static IntPtr CurrentBrowserHwnd = IntPtr.Zero;
public static int CurrentBrowserPID = -1;
        
ChromeOptions options = new ChromeOptions();
options.AddArgument("scriptpid-" + System.Diagnostics.Process.GetCurrentProcess().Id);
IWebDriver driver = new ChromeDriver(options);

// Get the PID and HWND details for a chrome browser

System.Diagnostics.Process[] processes = System.Diagnostics.Process.GetProcessesByName("chrome");
for (int p = 0; p < processes.Length; p++)
{
    ManagementObjectSearcher commandLineSearcher = new ManagementObjectSearcher("SELECT CommandLine FROM Win32_Process WHERE ProcessId = " + processes[p].Id);
    String commandLine = "";
    foreach (ManagementObject commandLineObject in commandLineSearcher.Get())
    {
        commandLine += (String)commandLineObject["CommandLine"];
    }

    String script_pid_str = (new Regex("--scriptpid-(.+?) ")).Match(commandLine).Groups[1].Value;

    if (!script_pid_str.Equals("") && Convert.ToInt32(script_pid_str).Equals(System.Diagnostics.Process.GetCurrentProcess().Id))
    {
        CurrentBrowserPID = processes[p].Id;
        CurrentBrowserHwnd = processes[p].MainWindowHandle;
        break;
    }
}

CurrentBrowserHwnd 应该包含您的Chrome窗口的HWND。

CurrentBrowserPID 应该包含您的Chrome窗口的进程ID。

我不知道。获取PID通常需要对Selenium代码进行一些修改。但是，您可以从系统而不是从Selenium本身获取PID。关于webdriver用户组的这个主题可能会有所帮助：
