如何从 Eclipse 中的 Java 代码启动 appium 服务器

Question

我正在尝试从我的测试用例代码以编程方式启动 appium 服务器，但没有任何帮助。控制台总是给我 "org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure" 错误消息。到目前为止我尝试了什么：

CommandLine command = new CommandLine("cmd");
command.addArgument("/c");
command.addArgument("C:/Program Files (x86)/Appium/node.exe");
command.addArgument("C:/Program Files (x86)/Appium/node_modules/appium/bin/appium.js");
        command.addArgument("--address");
        command.addArgument("127.0.0.1");
        command.addArgument("--bootstrap-port");
        command.addArgument("5001");
        command.addArgument("--no-reset");
        command.addArgument("--log");

无效。下一篇：

DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
        DefaultExecutor executor = new DefaultExecutor();
        executor.setExitValue(1);
        executor.execute(new CommandLine("C:/Program Files (x86)/Appium/node.exe"), resultHandler);
        executor.execute(new CommandLine("C:/Program Files (x86)/Appium/node_modules/appium/bin/Appium.js --address 127.0.0.1 --chromedriver-port 9516 --bootstrap-port 4725 --selendroid-port 8082 --no-reset --local-timezone"), resultHandler);

无效。下一篇：

ProcessBuilder pb = new ProcessBuilder("C:/Program Files(x86)/Appium/node.exe/");
        ProcessBuilder pb1 = new ProcessBuilder("C:/Program Files(x86)/Appium/node_modules/appium/bin/Appium.js --address 127.0.0.1 --chromedriver-port 9516 --bootstrap-port 5002 --no-reset --local-timezone");
        pb.start();
        pb1.start();

无效。下一篇：

String path = "cmd /c start C:/Users/jamesrobinson/Desktop/Run automation servers.bat";
        Runtime rn = Runtime.getRuntime();
        Process process = rn.exec(path);

我可以启动它的唯一方法是从 UI 手动启动它。任何解决方法的想法将不胜感激。

Answer 1

在分享屏幕截图之前，我只是猜测也许更改为 default 端口可能会帮助您成功创建会话：

command.addArgument("--bootstrap-port");
command.addArgument("4723");

一般的一行命令如下：

String command = "/Applications/Appium.app/Contents/Resources/node/bin/node /Applications/Appium.app/Contents/Resources/node_modules/appium/lib/server/main.js --command-timeout 120 --session-override" + nativelib + " --platform-name " + mobileOS + " --log-timestamp -a 0.0.0.0 -p "+4723; //+" --chromedriver-port "+chromePort+" -bp "+bootstrapPort;

其中

nativelib = " --native-instruments-lib"; //for iOS
nativelib = ""; //for android

和

mobileOS = "iOS"; //for iOS
mobileOS = "Android"; //for Android

                Explanation: 
                1. Create a command string and then write this command in some .bat file and then execute this .bat file.
                2. (Code not posted here for this ==> )After executing this, you need to put a wait until appium server is started, you can do this by sending request to http://localhost:4723, wait until you get response from this url and then you can initiate the driver.

                    //Getting temp dir
                    String tempDir = System.getProperty("java.io.tmpdir").toString();
                    logFile = new File(tempDir+"\applog.txt");

                    String commandFile = "C:\appium_commands.bat";

                    String nodeExe = "C:\node.exe";
                    String appiumJs = "C:\node_modules\appium\bin\Appium.js");

                    String strText = "start /B " + nodeExe + "  " + appiumJs + " -g " + logFile.toString() + " --full-reset --command-timeout 90 ";

                    logger.info("****** STARTING APPIUM SERVER USING COMMAND: "+strText);

                    WriteTextInFile(commandFile, strText);
                    Runtime.getRuntime().exec(commandFile);

            *********************  Code to Write Text in File  ***********
            WriteTextInFile(String commandFile, String strText)
           {
            FileWriter writer = new FileWriter(file);
            writer.write(strText);
            writer.close();
          }

          ************ Code to Send GET Request and Check Response *******
    //In this code, you can keep on checking until you get NON-Empty //result.tostring(); Also download and add apache httpclient-4.XXX.jar and //httpcore-4.XXX.jar to your project.

前置条件：

确保您的系统中安装了 nodejs
确保您的系统中安装了 appium。

--在下面给定的脚本中输入两者的位置。

public class mainClass{

AppiumDriverLocalService service;

@Test

public void  startSErver(){


    service=AppiumDriverLocalService.buildService(new AppiumServiceBuilder()
            .usingDriverExecutable(new File("C:\Program Files\nodejs\node.exe"))
            .withAppiumJS(new File("C:\Program Files (x86)\Appium\node_modules\appium\bin\appium.js"))
            .withIPAddress("127.0.0.1").usingPort(4723));

 service.start(); // To start the appium  server
