[英]Unable to run Headless Chrome Browser on Linux Machine using Selenium Webdriver java
[英]Unable to invoke headless chrome driver through Selenium webdriver(Java) in Heroku
我在 heroku 環境中調用無頭 chrome 並在 WINDOWS(本地機器)中完美運行時遇到了一個問題。
錯誤:

代碼截圖:
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 環境,所以很少有專門為 Linux env 添加的條件。
提前致謝!!!
在發布這個問題之前和之后,投入了足夠的時間來解決這個問題。 我很高興地說它成功了。
解決方法:
我已經指定了驅動程序路徑(在腳本中)並在 heroku env 中添加了驅動程序構建包。 驅動程序路徑造成了問題。 因此,只需刪除以下類似 heroku env 的代碼並僅添加到 Windows
System.setProperty("webdriver.chrome.driver", driverPath);
因此,代碼看起來像
public WebDriver launchBrowser(){
String driverPath="";
if(getOS().equals(OS.WINDOWS)){
driverPath="agent//chromedriver.exe";
System.setProperty("webdriver.chrome.driver", driverPath);
}
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){
}
}
WebDriver driver=new ChromeDriver(options);
return driver;
}
總結一下在 Heroku 中設置“調用 Headless chrome 的 selenium webdriver java 腳本”的整個方法:
將以下構建包添加到英雄應用程序
Heroku/Java
在 heroku 應用程序中部署代碼
謝謝大家!
添加構建包的命令。
heroku buildpacks:set heroku/java
heroku buildpacks:add --index 1 https://github.com/heroku/heroku-buildpack-google-chrome
heroku buildpacks:add --index 2 https://github.com/heroku/heroku-buildpack-chromedriver
