硒网格 3 节点中的 Chromedriver 设置

Question

My StartSeleniumGridNode.bat file.

java -jar selenium-server-standalone-3.4.0.jar -role node -hub http://127.0.0.1:4444/grid/register ^
-browser "browserName=firefox,maxInstances=3,platform=WINDOWS" ^
-browser "browserName=chrome,maxInstances=2,platform=WINDOWS" -Dwebdriver.chrome.driver="D:SeleniumGridPracticedriverschromedriver.exe"

这是我在控制台中遇到的错误。

注意：StartSeleniumGridHub.bat运行良好。火狐也没有问题。

请更改

java -jar selenium-server-standalone-3.4.0.jar -role node -hub http://127.0.0.1:4444/grid/register -browser "browserName=firefox,maxInstances=3,platform=WINDOWS" -browser "browserName=chrome,maxInstances=2,platform=WINDOWS" -Dwebdriver.chrome.driver="D:SeleniumGridPracticedriverschromedriver.exe"

自

java -Dwebdriver.chrome.driver="D:SeleniumGridPracticedriverschromedriver.exe" -jar selenium-server-standalone-3.4.0.jar -role node -hub http://127.0.0.1:4444/grid/register -browser "browserName=firefox,maxInstances=3,platform=WINDOWS" -browser "browserName=chrome,maxInstances=2,platform=WINDOWS"

然后重试。

解释：

JVM参数(以-D开头的参数(应该在参数之前提供-jar。但是由于您在-jar之后提供了它，而不是将其视为 JVM 参数，因此将其作为命令行参数提供给selenium-server独立 jar。
