...暗示 OsProcess 无法绑定到您系统中分配的 空闲端口.

根据讨论 获取无效端口错误.
和 端口无效.正在退出...
端口无效.退出……"当分配给 chromedriver 的端口小于 0 或大于 65535 时发生.
netstat
命令以查看您是否已达到可能打开的连接的限制或检查给定端口上是否有另一个应用程序正在运行.@Test
.
netstat
command through CLI to see if you have reached limit of possible open connections or check if there is another application running on the given port.@Test
.注意:步骤 1、2、7 和 8 对于调试/解决您当前面临的问题至关重要.
Note : Steps 1, 2, 7 and 8 are vital to debug/solve the issue you are currently facing.
作为替代方案,您可以强制 WebDriver 变体,即 ChromeDriver 在特定端口上启动,例如65530
如下:
As an alternative you can force the WebDriver variant i.e. ChromeDriver to start on a specific port e.g. 65530
as follows:
代码块:
Code Block:
System.setProperty("webdriver.chrome.driver","C:\WebDrivers\chromedriver.exe");
WebDriver driver= new ChromeDriver(new ChromeDriverService.Builder().usingPort(65530).build());
driver.get("https://www.google.com/");
控制台输出:
Console Output:
Starting ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103@{#416}) on port 65530
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.
