# 屏幕截图 对当前的视窗（viewport）、窗口（window）、页面（page）进行截图 ## 使用样例 ```java // Java File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); ``` ```python # Python screenshotBase64 = self.driver.get_screenshot_as_base64() ``` ```javascript // Javascript // webdriver.io example let screenshot = driver.takeScreenshot(); // wd example let screenshot = await driver.takeScreenshot(); ``` ```ruby # Ruby # ruby_lib example driver.screenshot_as(:base64) # via core_lib # ruby_lib_core example @driver.screenshot_as(:base64) ``` ```php # PHP // TODO PHP sample ``` ```csharp // C# Screenshot screenshot = driver.GetScreenshot(); ``` ## 描述 在原生环境（iOS、Android）中获取视窗（viewport）的屏幕截图，在web环境中获取窗口（window）的屏幕截图 需要注意的是，一些平台基于安全原因可能会有防止获取屏幕截图的设置。[Android FLAG_SECURE layout parameter](https://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_SECURE)就是一个这样类型的功能。 ## 支持 ### Appium Server | 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) | 4.3+ | All | All | | Mac | [Mac](../../drivers/mac.md) | ?+ | 1.6.4+ | All | | Windows | [Windows](../../drivers/windows.md) | 10+ | 1.6.0+ | All | ### Appium客户端 | 语言 | 支持版本 | 文档 | |--------|-------|-------------| |[Java](https://github.com/appium/java-client/releases/latest)| All | [seleniumhq.github.io](https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/remote/RemoteWebDriver.html#getScreenshotAs-org.openqa.selenium.OutputType-) | |[Python](https://github.com/appium/python-client/releases/latest)| All | [selenium-python.readthedocs.io](http://selenium-python.readthedocs.io/api.html#selenium.webdriver.remote.webdriver.WebDriver.get_screenshot_as_base64) | |[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#L1089) | |[Ruby](https://github.com/appium/ruby_lib/releases/latest)| All | [www.rubydoc.info](https://www.rubydoc.info/github/appium/ruby_lib_core/Appium/Core/Base/TakeScreenshot#screenshot_as-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 `GET /session/:session_id/screenshot` ### URL参数 | 名称 | 描述 | |----|-----------| |session_id|将指令发往的会话（session）的ID| ### JSON参数 None ### 响应 使用base64编码的PNG格式的屏幕截图 (`string`) ## 参考 * [W3C Specification](https://www.w3.org/TR/webdriver/#dfn-take-screenshot) * [JSONWP Specification](https://github.com/SeleniumHQ/selenium/wiki/JsonWireProtocol#sessionsessionidscreenshot) 本文由 [KangarooChen](https://github.com/KangarooChen) 翻译，Last english version: d05573600bb3ef2663a9c1e37a02c2ff5ec62155, 31 Dec 2019
