getMessaging 失败 - 未捕获语法错误：无法在模块外部使用 import 语句（位于 firebase-messaging-sw.js:1:1）

Question

我正在尝试将 firebase 消息传递集成到我的 NextJS Web 应用程序中，但收到的错误可能看起来像是来自服务器端。为了让注册在 _app.tsx 中工作，我执行以下操作：

  useEffect(() => {
    if ("serviceWorker" in navigator) {
      window.addEventListener("load", function () {
        const config = process.env.NEXT_PUBLIC_FIREBASE;
        navigator.serviceWorker.register("/firebase-messaging-sw.js?firebaseConfig=" + Buffer.from(config).toString('base64'), {
          type: 'module'
        }).then(
          function (registration) {
            console.log("Service Worker registration successful with scope: ", registration.scope);
          },
          function (err) {
            console.log("Service Worker registration failed: ", err);
          }
        );
      });
    }
  }, [])

其中 NEXT_PUBLIC_FIREBASE 是 firebase 配置对象。

然后在 public/firebase-messaging-sw.js 中我有这个：

import { initializeApp } from "https://www.gstatic.com/firebasejs/9.8.1/firebase-app.js";
import { getMessaging } from "https://www.gstatic.com/firebasejs/9.8.1/firebase-messaging.js";

const swScriptUrl = new URL(self.location);

const base64Config = swScriptUrl.searchParams.get('firebaseConfig')
let decoded = atob(base64Config);

const firebaseConfig = JSON.parse(decoded);
const app = initializeApp(firebaseConfig);


// Retrieve an instance of Firebase Messaging so that it can handle background
const messaging = getMessaging(app);

当调用 getMessaging 时，我收到此错误：

Uncaught SyntaxError: Cannot use import statement outside a module (at firebase-messaging-sw.js:1:1)

我已经检查了配置对象，它绝对是正确的，并将其发送给服务工作人员（也尝试仅复制配置但无济于事）。

尝试让它在本地和 https 服务器上工作但无济于事，我还尝试了 none 模块导入，它产生了相同的错误。

同样的事情也发生在我身上，第一个是使用 importScripts ，第二个是降级到 8.0.0 并稍微更改函数调用。正如我在下面向您展示的：

   importScripts("https://www.gstatic.com/firebasejs/8.0.0/firebase-app.js");
   importScripts("https://www.gstatic.com/firebasejs/8.0.0/firebase-messaging.js");
    
    const swScriptUrl = new URL(self.location);
    
    const base64Config = swScriptUrl.searchParams.get('firebaseConfig')
    let decoded = atob(base64Config);
    
    const firebaseConfig = JSON.parse(decoded);
    const app = firebase.initializeApp(firebaseConfig);
    
    
    // Retrieve an instance of Firebase Messaging so that it can handle background
    const messaging = firebase.messaging();
