连接到127.0.0.1:4723 [/127.0.0.1]失败:连接被拒绝:连接

Question

我正在尝试编写我的第一个测试。

每次运行代码时，都会出现以下错误：

org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:4723 [/127.0.0.1] failed: Connection refused: connect  
....  
at MyFirstTest.setupTest(MyFirstTest.java:52)  
Caused by: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:4723 [/127.0.0.1] failed: Connection refused: connect  
at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:158)  
at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:353)  

这是我的代码：

public class MyFirstTest  
{  
    public AppiumDriver<MobileElement> driver;  
    public WebDriverWait wait;  
    String usersEmail = "xxxx@gmail.com";  
    String userPassword = "aaaaaa";  

    public void login() throws InterruptedException  
    {  
        WebElement email = driver.findElement(By.xpath("//android.widget.EditText[contains(@text,'Enter Email')]"));  
        email.sendKeys(usersEmail);  
        Sleeper.SYSTEM_SLEEPER.sleep(new Duration(1000, TimeUnit.MILLISECONDS));  
        driver.findElement(By.xpath("//android.widget.RelativeLayout[contains(@resource-id,'edtPassword')]//android.widget.EditText[contains(@resource-id,'edtText')]")).sendKeys(userPassword);  
    driver.findElement(By.xpath("//android.widget.Button[contains(@resource-id,'btnLogin')]")).click();  
    }  
    @Before  
    public void setupTest() throws Exception  
    {  
        DesiredCapabilities capabilities = new DesiredCapabilities();  
        capabilities.setCapability("platormName", "Android");  
        capabilities.setCapability("deviceName", "Redmi");  
        capabilities.setCapability("appPackage","com.ls.stockpair");  
        capabilities.setCapability("appActivity","com.ls.stockpair.activity.SplashActivity");  
        driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);  
        Thread.sleep(8000);  
    }  
    @Test  
    public void go() throws InterruptedException  
    {  

    WebElement email = driver.findElement(By.xpath("//android.widget.EditText[contains(@text,'Enter Email')]"));  
    email.sendKeys(usersEmail);  
    Sleeper.SYSTEM_SLEEPER.sleep(new Duration(1000, TimeUnit.MILLISECONDS));  
    driver.findElement(By.xpath("//android.widget.RelativeLayout[contains(@resource-id,'edtPassword')]//android.widget.EditText[contains(@resource-id,'edtText')]")).sendKeys(userPassword);  
    driver.findElement(By.xpath("//android.widget.Button[contains(@resource-id,'btnLogin')]")).click();  

    Sleeper.SYSTEM_SLEEPER.sleep(new Duration(2000, TimeUnit.MILLISECONDS));  
        }  
}  

目前，在运行代码之前，我正在手动启动Appium。还试图从代码中启动Appium --这并没有帮助。

这段代码在我开始编写这段代码的第一天就起作用了，但不知为什么(我真的不知道为什么)，它就停止工作了。

我在网上看到了很多关于这个问题的不同答案的问题，但到目前为止没有人帮助我。

我正在使用一个真正的Android设备，通过USB连接到我的Windows机器上。

下面是最好的解决方案，您不需要每次都手动启动appium。

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

    service = AppiumDriverLocalService.buildDefaultService();
    DesiredCapabilities capabilities = new DesiredCapabilities();  
    capabilities.setCapability("platormName", "Android");  
    capabilities.setCapability("deviceName", "Redmi");  
    capabilities.setCapability("appPackage","com.ls.stockpair");  
    capabilities.setCapability("appActivity","com.ls.stockpair.activity.SplashActivity");  

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

注意:如果您使用的是appium版本的1.5.3+，那么需要在环境变量.中设置APPIUM_BINARY_PATH。

例如APPIUM_BINARY_PATH=C:\Users\YourUserName\AppData\Roaming\npm\node_modules\appium\build\lib\main.js

有关如何设置APPIUM_BINARY_PATH的详细信息，请参阅下面的屏幕快照：
