如何在 windows 机器上通过 Java 代码调用 appium 服务器和模拟器

Question

我需要使用 Selenium 通过 Java 代码启动 Appium 服务器和模拟器。当我运行 Java 程序 startappiumserver 方法运行良好。当谈到 startApplication 方法 （创建新的 remoteWebDriver） 我收到如下错误：

线程异常 "main" org.openqa.selenium.remote.UnreachableBrowserException: 无法启动新会话。 可能的原因是远程服务器地址无效或浏览器启动失败。

代码：

package startup;

import io.appium.java_client.AppiumDriver;

import java.io.IOException;
import java.net.URL;

import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecuteResultHandler;
import org.apache.commons.exec.DefaultExecutor;
import org.apache.commons.exec.ExecuteException;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class Startup {

    static RemoteWebDriver driver = null;

    public void startAppiumServer() throws IOException, InterruptedException {   

        CommandLine command = new CommandLine("cmd");
        command.addArgument("/c");

        command.addArgument("D:\SOFTWARES\AppiumForWindows-1.2.4.1\Appium\node.exe");  
        command.addArgument("D:\SOFTWARES\AppiumForWindows-1.2.4.1\Appium\node_modules\appium\lib\appium.js");  
        command.addArgument("--address", false);  
        command.addArgument("127.0.0.1");  
        command.addArgument("--port", false);  
        command.addArgument("4723");  
        command.addArgument("--full-reset", false);  

        DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();  
        DefaultExecutor executor = new DefaultExecutor();  
        executor.setExitValue(1);
        executor.execute(command, resultHandler);
    }


    public  void stopAppiumServer() throws IOException {  
        CommandLine command = new CommandLine("cmd");  
        command.addArgument("/c");  
        command.addArgument("Taskkill /F /IM node.exe");  

        DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();  
        DefaultExecutor executor = new DefaultExecutor();  
        executor.setExitValue(1);  
        executor.execute(command, resultHandler);  

    }

public static  void startApplication() throws Exception{


        System.out.println("application has started...................");

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "");            
        capabilities.setCapability("deviceName","emulator-5554");   
        capabilities.setCapability("platformVersion","4.3");
        capabilities.setCapability("platformName","Android");
        capabilities.setCapability("app","D:/SOFTWARES/Apks/autoInsurancelatest.apk");
        driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities); 
        System.out.println("Appium SetUp for Android is successful and Appium Driver is launched successfully");
    }

    public static void main(String as[]) throws Exception
    {
        Startup aps = new Startup();

        System.out.println("Starting Server...");

        aps.startAppiumServer();
        System.out.println("Server Started....");
        try{Thread.sleep(5000);}catch(Exception e){}  

        Startup.startApplication();
        try{Thread.sleep(5000);}catch(Exception e){}

        System.out.println("Stopping Server");
        aps.stopAppiumServer();
        System.out.println("Server Stopped");
    }

}

我发现在创建新的 remotewebdriver 时有一些 port 错误。我没有找到代码中缺少的内容。

帮我解决这个问题。欢迎提出建议和意见。

Answer 1

能否请您对代码进行以下更改：

1) 从 bin 目录而不是从 lib

中获取 appium.js

2) 添加以下内容

command.addArgument("--bootstrap-port",false);
command.addArgument("4724",false);
command.addArgument("--selendroid-port",false);
command.addArgument("8082",false);

另外请确保您有足够的时间直到 appium 启动。详情请看这个。

如果问题仍然存在，请复制您的代码构建的命令字符串并尝试从 cmd 启动它。
