# 启动应用 在设备上启动被测应用 ## 用法示例 ```java // Java driver.launchApp(); ``` ```python # Python self.driver.launch_app() ``` ```javascript // Javascript // webdriver.io example driver.launchApp(); // wd example await driver.launchApp(); ``` ```ruby # Ruby # ruby_lib example launch_app # ruby_lib_core example @driver.launch_app ``` ```php # PHP $driver->launchApp(); ``` ```csharp // C# // TODO C# sample ``` ## 描述 如果被测应用（AUT）已关闭或在后台运行，它将启动它。如果AUT已打开，它将使其放到后台并重新启动。 使用XCUITest的iOS测试也可以使用“ mobile：launchApp”方法。详见[文档](../writing-running-appium/ios/ios-xctest-mobile-apps-management.md#mobile-launchapp)。 ## 支持 ### Appium服务器 |平台|Driver|平台版本|Appium版本|Driver版本| |--------|----------------|------|--------------|--------------| | iOS | [XCUITest](../../drivers/ios-xcuitest.md) | 9.3+ | 1.6.0+ | All | | | [UIAutomation](../../drivers/ios-uiautomation.md) | 8.0 to 9.3 | All | All | | Android | [Espresso](../../drivers/android-espresso.md) | ?+ | 1.9.0+ | All | | | [UiAutomator2](../../drivers/android-uiautomator2.md) | ?+ | 1.6.0+ | All | | | [UiAutomator](../../drivers/android-uiautomator.md) | 4.2+ | All | All | | Mac | [Mac](../../drivers/mac.md) | None | None | None | | Windows | [Windows](../../drivers/windows.md) | None | None | None | ### Appium客户端 |语言|支持版本|文档| |--------|-------|-------------| |[Java](https://github.com/appium/java-client/releases/latest)| All | [appium.github.io](https://appium.github.io/java-client/io/appium/java_client/InteractsWithApps.html#launchApp--) | |[Python](https://github.com/appium/python-client/releases/latest)| All | [github.com](https://github.com/appium/python-client/blob/master/README.md#closing-and-launching-an-application) | |[Javascript (WebdriverIO)](http://webdriver.io/index.html)| All | | |[Javascript (WD)](https://github.com/admc/wd/releases/latest)| All | [github.com](https://github.com/admc/wd/blob/master/lib/commands.js#L2798) | |[Ruby](https://github.com/appium/ruby_lib/releases/latest)| All | [www.rubydoc.info](https://www.rubydoc.info/github/appium/ruby_lib_core/Appium/Core/Device#launch_app-instance_method) | |[PHP](https://github.com/appium/php-client/releases/latest)| All | [github.com](https://github.com/appium/php-client/) | |[C#](https://github.com/appium/appium-dotnet-driver/releases/latest)| All | [github.com](https://github.com/appium/appium-dotnet-driver/) | ## HTTP API规范 ### 终端 `POST /session/:session_id/appium/app/launch` ### URL参数 |名称|描述| |----|-----------| |session_id|将指令发往的会话（session）ID| ### JSON参数 无 ### 响应 null ## 参考 * [JSONWP 规范](https://github.com/appium/appium-base-driver/blob/master/lib/protocol/routes.js#L539) --- EOF. 本文由 [zhangfeng](https://github.com/zhangfeng91)翻译，Last english version: a11f693bbe2bcf2e47fa6a40872a7580ab45d6bb, 6 Jun 2020
