# 获取当前Context 获取Appium运行时的当前Context ## 使用示例 ```java // Java String context = driver.getContext(); ``` ```python # Python context = driver.current_context # or context = driver.context ``` ```javascript // Javascript // webdriver.io example let context = driver.getContext(); // wd example let context = await driver.currentContext(); ``` ```ruby # Ruby # ruby_lib example context = current_context # ruby_lib_core example context = @driver.current_context ``` ```php # PHP $context = $driver->context(); ``` ```csharp // C# string Context = driver.Context; ``` ## 描述 查找目前的context. 它有可能是原生的context: `NATIVE_APP` ，也可能是webview的context: * iOS - `WEBVIEW_<id>` * Android - `WEBVIEW_<package name>` 想了解contexts的相关信息，可点击查看Appium的[自动化混合应用](../writing-running-appium/web/hybrid.md). ## 支持 ### Appium 服务端 |Platform|Driver|Platform Versions|Appium Version|Driver Version| |--------|----------------|------|--------------|--------------| | 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) | 4.3+ | All | All | | Mac | [Mac](../../drivers/mac.md) | None | None | None | | Windows | [Windows](../../drivers/windows.md) | None | None | None | ### Appium 客户端 |Language|Support|Documentation| |--------|-------|-------------| |[Java](https://github.com/appium/java-client/releases/latest)| All | [appium.github.io](https://appium.github.io/java-client/io/appium/java_client/AppiumDriver.html#getContext--) | |[Python](https://github.com/appium/python-client/releases/latest)| All | [appium.github.io](https://appium.github.io/python-client-sphinx/webdriver.extensions.html#webdriver.extensions.context.Context.current_context) | |[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/doc/api.md) | |[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#current_context-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 ### 路径 `GET /session/:session_id/context` ### URL参数 |名称|描述| |----|-----------| |session_id|新建会话(session)后用来标识当前会话(session)的ID| ### JSON参数 无 ### 响应 当前context的名称(`String`) ## 参考 * [JSONWP 规范](https://github.com/SeleniumHQ/mobile-spec/blob/master/spec-draft.md#webviews-and-other-contexts)
