# 设置当前Context 设置Context ## 使用示例 ```java // Java Set<String> contextNames = driver.getContextHandles(); driver.context(contextNames.toArray()[1]); // ... driver.context("NATIVE_APP"); ``` ```python # Python webview = driver.contexts[1] driver.switch_to.context(webview) # ... driver.switch_to.context('NATIVE_APP') ``` ```javascript // Javascript // webdriver.io example let contexts = driver.getContexts(); driver.switchContext(contexts[1]); // ... driver.switchContext('NATIVE_APP'); // wd example let contexts = await driver.contexts(); await driver.context(contexts[1]); // ... await driver.context('NATIVE_APP'); ``` ```ruby # Ruby # ruby_lib example webview = available_contexts[1] set_context(webview) # ... set_context('NATIVE_APP') # ruby_lib_core example webview = @driver.available_contexts[1] @driver.set_context(webview) # ... @driver.set_context('NATIVE_APP') ``` ```php # PHP $contexts = $driver->contexts(); $driver->context($contexts[1]); // ... $driver->context('NATIVE_APP'); ``` ```csharp // C# // Switch to specific webview List<string> AllContexts = new List<string>(); foreach (var context in (driver.Contexts)) { AllContexts.Add(context); } driver.Context = (AllContexts[1]); // Switch to NATIVE_APP driver.Context = ("NATIVE_APP"); ``` ## 描述 通过传入的context来设置当前的context，如果是设置webview为当前的context，则将尝试与web view进行连接: * iOS - 通过远程调试(remote debugger)与web view进行连接 * Android - 启动[Chromedriver](../writing-running-appium/web/chromedriver.md) 进程去创建一个会话(session)与web view进行连接 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#context-java.lang.String-) | |[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.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#set_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 `POST /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 |名称|类型|描述| |----|----|-----------| | name | `String` | 要设置的context的名称 | ### 响应 null ## 参考 * [JSONWP 规范](https://github.com/SeleniumHQ/mobile-spec/blob/master/spec-draft.md#webviews-and-other-contexts)
