+获取包含了有关调用该方法的附加组件的信息的 {{WebExtAPIRef("management.ExtensionInfo", "ExtensionInfo")}} 对象。
+
+此 API *不*需要“management”[API 权限](/zh-CN/docs/Mozilla/Add-ons/WebExtensions/manifest.json/permissions)。
+
+这是一个返回 [`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise) 的异步函数。
+
+## 语法
+
+```js-nolint
+let gettingSelf = browser.management.getSelf()
+```
+
+### 参数
+
+无。
+
+### 返回值
+
+[`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise)，会兑现为包含有关附加组件的信息的 {{WebExtAPIRef("management.ExtensionInfo", "ExtensionInfo")}} 对象。
+
+## 浏览器兼容性
+
+{{Compat}}
+
+## 示例
+
+打印附加组件的名称：
+
+```js
+function gotSelf(info) {
+  console.log(`附加组件名：${info.name}`);
+}
+
+const gettingSelf = browser.management.getSelf();
+gettingSelf.then(gotSelf);
+```

+> [!NOTE]
+> 该 API 基于 Chromium 的 [`chrome.management`](https://developer.chrome.google.cn/docs/extensions/reference/api/management#method-getSelf) API。本文衍生自 Chromium 代码中的 [`management.json`](https://chromium.googlesource.com/chromium/src/+/master/extensions/common/api/management.json)。
