在Mac上，Appium服务器将无法通过Java从Eclipse启动

Question

当我尝试使用Java从e​​clipse启动我的Appium服务器时，出现错误消息“ org.openqa.selenium.WebDriverException：连接被拒绝”，我一直对此感到困惑，并且我不知道自己在做什么错。 任何帮助，将不胜感激

这是控制台日志：

这是我的Appium服务器类代码。 每当我启动服务器，然后尝试连接到服务器时，都会收到错误消息。

公共类AppiumServer {

public void startServer() {
    System.out.println("entered start server");
    CommandLine command = new CommandLine(
            "/Applications/Appium.app/Contents/Resources/node/bin/node");
    command.addArgument(
            "/Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js",
            false);
    command.addArgument("--address", false);
    //command.addArgument("http://localhost:");
    command.addArgument("127.0.0.1");
    command.addArgument("--port", false);
    command.addArgument("4723");
    command.addArgument("--full-reset", false);
    System.out.println("commands given");
    DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();




    DefaultExecutor executor = new DefaultExecutor();
    executor.setExitValue(1);
    System.out.println("Attempting to start server");
    try {
        executor.execute(command, resultHandler);


        Thread.sleep(5000);
        System.out.println("Appium server started.");
    } catch (IOException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

public void stopServer() {
    String[] command = { "/usr/bin/killall", "-KILL", "node" };
    try {
        Runtime.getRuntime().exec(command);
        System.out.println("Appium server stopped.");
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}

这是调用类，直到失败为止。 如果我通过打开Appium手动启动服务器，则该类成功连接。 我很确定当我尝试通过Eclipse启动服务器时服务器没有启动。

public static AppiumServer server = new AppiumServer();
@BeforeSuite
public void setUp() throws MalformedURLException {

System.out.println("Before suite started.");

server.startServer();

DesiredCapabilities capabilities = new DesiredCapabilities();
    // Set ios deviceName desired capability. Set your device name.
    capabilities.setCapability("deviceName", "My iPhone");
    // Set BROWSER_NAME desired capability. It’s iOSin our case here.
    capabilities.setCapability(CapabilityType.BROWSER_NAME, "iOS");
    // Set iOS VERSION desired capability. Set your mobile device’s OS version.
    capabilities.setCapability(CapabilityType.VERSION, "11.2.6");
    // Set iOS platformName desired capability. It’s Android in our case here.
    capabilities.setCapability("noReset", false);
    capabilities.setCapability("platformName", "iOS");
    //capabilities.setCapability("platformVersion", "7.1.1");
    // Set your application’s appPackage if you are using any other app.
    capabilities.setCapability("xcodeSigningId", "iPhone Developer");
    capabilities.setCapability("appActivity", "com.<redacted>.<redacted>.<redacted>");
    // It will launch app in iOS device.
    capabilities.setCapability("udid", "<redacted>");
    capabilities.setCapability("xcodeOrgId", "<redacted>");
    capabilities.setCapability("automationName", "XCUITest");
    capabilities.setCapability("bundleId", "com.<redacted>.<redacted>");
    System.out.println("capabilities Set.");


    driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    System.out.println("connection suceeded");

Answer 1

有几种可能的解决方案：

Connection refused意味着由于某些原因，Appium服务器无法处理传入的请求。

1.检查可能的本地问题

检查是否尚未启动相同的进程或具有相同端口的进程。

2.认为是基于服务器的

或只是每次尝试都不运行Appium时尝试进行测试，打开服务器并将其保留为服务器应有的性能，始终运行并在需要时处理请求。 在开始时，我还尝试通过编程方式运行服务器来尝试此方法，但实际上没有必要，它速度较慢，需要维护，并且必须始终启动。 我的观点是这很耗时，并且没有必要。 从命令行/控制台启动它，有多种方法可以执行它，例如node.js，shell脚本，Appium服务器IDE。

这是最简单的命令（来自mac） appium --address 127.0.0.1 --port 4723

3.通过AppiumDriverLocalService可能的解决方案

AndroidDriver<MobileElement> driver=null;
AppiumDriverLocalService service=null;

service = AppiumDriverLocalService.buildDefaultService();

DesiredCapabilities capabilities = new DesiredCapabilities();  
capabilities.setCapability("platormName", "Android");  
capabilities.setCapability("deviceName", "yourAppUdid");  
capabilities.setCapability("appPackage","YourAppPackage");  
capabilities.setCapability("appActivity","yourAppActivity"); 


(or IOS)
DesiredCapabilities capabilities = new DesiredCapabilities();
// Set ios deviceName desired capability. Set your device name.
capabilities.setCapability("deviceName", "My iPhone");
// Set BROWSER_NAME desired capability. It’s iOSin our case here.
capabilities.setCapability(CapabilityType.BROWSER_NAME, "iOS");
// Set iOS VERSION desired capability. Set your mobile device’s OS version.
capabilities.setCapability(CapabilityType.VERSION, "11.2.6");
// Set iOS platformName desired capability. It’s Android in our case here.
capabilities.setCapability("noReset", false);
capabilities.setCapability("platformName", "iOS");
//capabilities.setCapability("platformVersion", "7.1.1");
// Set your application’s appPackage if you are using any other app.
capabilities.setCapability("xcodeSigningId", "iPhone Developer");
capabilities.setCapability("appActivity", "com.<redacted>.<redacted>.<redacted>");
// It will launch app in iOS device.
capabilities.setCapability("udid", "<redacted>");
capabilities.setCapability("xcodeOrgId", "<redacted>");
capabilities.setCapability("automationName", "XCUITest");
capabilities.setCapability("bundleId", "com.<redacted>.<redacted>");
System.out.println("capabilities Set.");

service.start();

driver = new AndroidDriver<MobileElement>(service, capabilities);

注意：如果您使用的Appium版本是1.5.3或更高版本，则必须在环境变量中设置APPIUM_BINARY_PATH。

例如APPIUM_BINARY_PATH = ... \\ node_modules \\ appium \\ build \\ lib \\ main.js

希望这可以帮助，
