如何喂食正确的参数吗？

Question

我想有以下功能连接到Android模拟器：

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); 
} 

而且不断收到以下错误参数错误：

[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 

我检查了很多次的输入能力，他们似乎据我所知，还是应该使用别的东西？

Appium服务器：v1.6.4 硒的Java：V3.3.1

Answer 1

这个错误是因为你使用的是硒的Java：V3.3.1不正确的Appium Java客户端

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

只能从最新的appium java客户端5.0.0-BETA7才有可能使用selenium-java：v3.3.1。

或者你可以将selenium-java恢复到2.53.1
