及其开发中需要注意的安全风险。ServiceExtensionAbility主要用于后台运行的不提供用户交互界面的服务。目前，ServiceExtensionAbility 能力的使用需要应用标记为系统应用，三方应用即非系统应用需要使用后台任务。</p><p data-tool="markdown.com.cn编辑器" style="padding-top: 8px;padding-bottom:

26px;">ServiceExtensionAbility是SERVICE类型的ExtensionAbility组件，提供后台服务能力，其内部持有了一个ServiceExtensionContext，通过ServiceExtensionContext提供了丰富的接口供外部使用。ServiceExtensionAbility可以被其他组件启动或连接，并根据调用者的请求信息在后台处理相关事务。ServiceExtensionAbility支持以启动和连接两种形式运行，系统应用可以调用startServiceExtensionAbility()方法启动后台服务，也可以调用connectServiceExtensionAbility()方法连接后台服务，而三方应用只能调用connectServiceExtensionAbility()方法连接后台服务。启动和连接后台服务的差别：</p><ul

服务被首次创建时触发该回调，开发者可以在此进行一些初始化的操作，例如注册公共事件监听等。说明：如果服务已创建，再次启动该ServiceExtensionAbility不会触发onCreate()回调。</section></li><li><section style="margin-top: 5px;margin-bottom: 5px;line-height: 26px;text-align:

0.05);font-family: &#34;Operator Mono&#34;, Consolas, Monaco, Menlo, monospace;word-break: break-all;">onRequest</code> 当另一个组件调用startServiceExtensionAbility()方法启动该服务组件时，触发该回调。执行此方法后，服务会启动并在后台运行。每调用一次startServiceExtensionAbility()方法均会触发该回调。</section></li><li><section style="margin-top: 5px;margin-bottom:

当另一个组件调用connectServiceExtensionAbility()方法与该服务连接时，触发该回调。开发者在此方法中，返回一个远端代理对象（IRemoteObject），客户端拿到这个对象后可以通过这个对象与服务端进行RPC通信，同时系统侧也会将该远端代理对象（IRemoteObject）储存。后续若有组件再调用connectServiceExtensionAbility()方法，系统侧会直接将所保存的远端代理对象（IRemoteObject）返回，而不再触发该回调。</section></li><li><section

当最后一个连接断开时，将触发该回调。客户端死亡或者调用disconnectServiceExtensionAbility()方法可以使连接断开。</section></li><li><section style="margin-top: 5px;margin-bottom: 5px;line-height: 26px;text-align: left;color: rgb(1, 1,

Mono&#34;, Consolas, Monaco, Menlo, monospace;word-break: break-all;">onDestroy</code> 当不再使用服务且准备将其销毁该实例时，触发该回调。开发者可以在该回调中清理资源，如注销监听等。</section></li></ul><h1 data-tool="markdown.com.cn编辑器"

8px;line-height: 26px;">在开始之前，我们需要了解如下准备工作，因为只有系统应用才允许实现ServiceExtensionAbility，所以我们需要将目标应用的签名指纹配置到设备的特权管控白名单，这种开发场景适用于设备提供商自行开发提供某些系统服务，或者三方应用开发者向设备提供商申请添加白名单。因为我们这里是本地测试，所以可以直接按后文步骤修改系统配置来完成：</p><ul

data-tool="markdown.com.cn编辑器" style="padding-top: 8px;padding-bottom: 8px;line-height: 26px;">部分开发者需要使用ServiceExtension提供一些较为敏感的服务，因此需要对客户端身份进行校验，开发者可在IDL接口的stub端进行校验，IDL接口实现详见定义IDL接口（<a

接口获取客户端的uid，再调用<code style="font-size: 14px;padding: 2px 4px;border-radius: 4px;margin-right: 2px;margin-left: 2px;color: rgb(30, 107, 184);background-color: rgba(27, 31, 35, 0.05);font-family:

那么对应的解决方案在安卓中通过重写WebView的shouldOverrideUrlLoading方法，在发起请求前得到一次回调处理的机会，可以检测将请求的url的合法性。

那么在文章开始处，我们介绍了纯鸿蒙的webview的软件架构，其底层使用的是cef封装的chromium，那么纯鸿蒙的接口webwebview.WebviewController.loadUrl是否也是browser-initiated状态的导航操作？那么我们从代码跟踪的角度看一下webwebview.WebviewController.loadUrl的底层实现，调用栈如下</p><pre

: )</p><p style="white-space-collapse: preserve-breaks;line-height: 30px;color: rgb(74, 74, 74);">本文将从Openharmony源码编译到编写运行第一个纯鸿蒙应用，介绍应用间的数据交互及参数传递的载体，最后以一个null want的例子来介绍开发中可能存在的风险。<span style="color:

Ability）。FA/PA是应用的基本组成单元，能够实现特定的业务功能。FA有UI界面，而PA无UI界面。Page模板是FA唯一支持的模板，用于提供与用户交互的能力。我们可以简单理解为一个应用的每一个页面都对应一个 <code style="background: rgb(243, 241, 241);color: rgb(88, 88, 88);font-size:
