如何用正确的参数给appium喂食？

Question

我试图通过以下功能连接到Android仿真器：

public class SimpleAndroidCalcTest {

 WebDriver driver;

 @Before public void setUp() throws MalformedURLException {
     DesiredCapabilities capabilities = new DesiredCapabilities();
     capabilities.setCapability("platformName", "Android");
     capabilities.setCapability("platformVersion", "7.1.1");
     capabilities.setCapability("deviceName", "android-7");
     capabilities.setCapability("appPackage", "com.android.calculator2");
     capabilities.setCapability("appActivity", "com.android.calculator2.Calculator");

    driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
 }

并继续获取以下坏参数错误：

[HTTP] --> POST /wd/hub/session {"desiredCapabilities":{"appPackage":"com.android.calculator2","appActivity":"com.android.calculator2.Calculator","platformVersion":"7.1.1","platformName":"Android","deviceName":"android-7"},"requiredCapabilities":{},"capabilities":{"desiredCapabilities":{"appPackage":"com.android.calculator2","appActivity":"com.android.calculator2.Calculator","platformVersion":"7.1.1","platformName":"Android","deviceName":"android-7"},"requiredCapabilities":{}},"alwaysMatch":{"appPackage":"com.android.calculator2","appActivity":"com.android.calculator2.Calculator","platformVersion":"7.1.1","platformName":"Android","deviceName":"android-7"},"firstMatch":[]}
[MJSONWP] Bad parameters: BadParametersError: Parameters were incorrect. We wanted {"required":["desiredCapabilities"],"optional":["requiredCapabilities","capabilities","sessionId","id"]} and you sent ["desiredCapabilities","requiredCapabilities","capabilities","alwaysMatch","firstMatch"]
[HTTP] <-- POST /wd/hub/session 400 4 ms - 243

据我所知，我已经多次检查了输入功能，它们似乎是有效的，还是应该使用其他的功能？

Appium服务器: v1.6.4 selenium-java: v3.3.1

Answer 1

发生此错误是因为您使用的selenium-java : v3.3.1没有正确的Appium java客户端。

请参阅：https://github.com/appium/java-client

只有在最新的appium java客户机5.0.0-BETA7中，才有可能使用selenium-java : v3.3.1。

或者您可以将selenium-java恢复到2.53.1。
