appium 中的连接重置（WebDriver 异常）

Question

大家好，我得到了一个异常名称 webdriverException：在我的 IOS 脚本运行期间某些元素上的连接重置，我使用的是 appium v​​1.8.0。它不是每次都发生，而是在很多元素上都有一段时间，当我捕捉到这个异常并尝试使用相同的操作时，它会起作用。

下面给出的所有功能：

`cap.setCapability(MobileCapabilityType.PLATFORM_NAME, "iOS");
cap.setCapability(MobileCapabilityType.AUTOMATION_NAME, "XCUITest");
cap.setCapability(MobileCapabilityType.PLATFORM_VERSION, "11.4");
cap.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone 7 Plus");
cap.setCapability(MobileCapabilityType.BROWSER_NAME, "");
cap.setCapability(MobileCapabilityType.SUPPORTS_ALERTS,true);
cap.setCapability(MobileCapabilityType.CLEAR_SYSTEM_FILES,true);
cap.setCapability(MobileCapabilityType.SUPPORTS_FINDING_BY_CSS,true);
cap.setCapability ( "useNewWDA", true);
cap.setCapability ("webviewConnectRetries", "25" );
cap.setCapability( "usePrebuiltWDA", true );
cap.setCapability("simpleIsVisibleCheck",false);
cap.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT,"120");`

下面给出的例外情况：

尝试在驱动初始化之前添加System.setProperty("webdriver.http.factory", "apache")。
