无法通过Heroku中的Selenium webdriver(Java)调用headless chrome驱动程序
在heroku环境中调用headless chrome并在WINDOWS(本地机器)中完美运行时,我面临一个问题
错误:

代码剪报:
public WebDriver launchBrowser(){
String driverPath="";
if(getOS().equals(OS.WINDOWS)){
driverPath="agent//chromedriver.exe";
}else if(getOS().equals(OS.LINUX)){
driverPath="agent//chromedriver";
}
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("window-size=1200x600");
if(getOS().equals(OS.LINUX)){
try{ //GOOGLE_CHROME_SHIM GOOGLE_CHROME_BIN
String binaryPath=EnvironmentUtils.getProcEnvironment().get("GOOGLE_CHROME_SHIM");
System.out.println("Path: "+binaryPath);
options.setBinary(binaryPath);
options.addArguments("--disable-gpu");
options.addArguments("--no-sandbox");
}catch(Exception e){
}
}
System.out.println("Driver Path: "+driverPath);
System.setProperty("webdriver.chrome.driver", driverPath);
WebDriver driver=new ChromeDriver(options);
return driver;
}
Heroku是Linux环境,因此专门为Linux环境添加的条件很少
提前感谢
# 1 楼答案
事先及;发布此问题后,请投入足够的时间解决此问题。我很高兴地说,我们取得了成功
解决方案:
我已指定驱动程序路径(在脚本中)&;在heroku env中添加了驱动程序构建包。驱动程序路径造成了问题。因此,只需删除以下类似heroku env&;的代码;仅为windows添加
因此,代码看起来像
下面总结一下在Heroku中设置“调用Headless chrome的selenium webdriver java脚本”的整个方法:
谢谢大家
用于添加生成包的命令
