android - IndexedDB 在 WebView 中不起作用 - 为什么？

Question

我有一个需要使用本地存储（IndexedDB）的团队应用程序。

在最常见的浏览器上一切正常：Chrome、Firefox，但是当我尝试将应用程序与适用于 Teams 的 Android 应用程序一起使用时，出现问题：“应用程序的正确运行必须允许访问 IndexedDB”。

Android 版本：10 - WebView 版本：81.0.4044.138

从我的角度来看，这与使用 WebView 进行本地存储的权限有关

这是我的代码：

if (window.indexedDB) {

  var request = indexedDB.open('__mydb', 2);
    request.onerror = function (event) {
      alert('It is necessary for the correct functioning of the app to allow access to IndexedDB.');
    };
    request.onsuccess = function (event) {
      mydb = event.target.result;

      try {
        console.log('Database opened, checking existence of table');
        var objectStore = mydb.transaction([tableName], 'readwrite')
          .objectStore(tableName);

        console.log('Table exists. Proceeding to save data');
        saveTokenDataIndexedDB(objectStore);

        console.log('All done, going to app');
        goToApp();
      } catch (e) {
        console.log(e);
      }
    };
 }

这是我的 Teams 应用程序的清单文件：

  ],
  "webApplicationInfo": {
    "resource": "https://{teamSiteDomain}",
    "id": "XXXXXXXX-eadc-4020-b4e2-XXXXXXXXXX"
  }
}

我坚持这一点，如果有人可以给我一个线索，我将不胜感激。
