Cloud Firestore 未在控制台中显示复合索引链接

Question

我正在运行一个需要创建复合索引的查询。 AFAIK，有两种解决方法。

1. 进入控制台，手动创建索引。

2. 按原样运行查询，以在控制台中收到错误，创建索引后可以将我引导至 Firebase 控制台。

但我在控制台上没有看到任何此类链接。这是查询：

collection.where('foo', isEqualTo: 'bar').where('baz', isLessThan: 1);

错误：

E/flutter (21010): [ERROR:flutter/lib/ui/ui_dart_state.cc(207)] Unhandled Exception: [cloud_firestore/failed-precondition] Operation was rejected because the system is not in a state required for the operation's execution. If performing a query, ensure it has been indexed via the Firebase console.

Answer 1

显然 Firebase 已停止在客户端 SDK 中返回索引创建链接。您仍然可以在 Cloud Function 中使用 Admin SDK 来获取直接索引创建链接或自己手动创建一个，如下所示：

确保将集合和字段名称替换为原始名称。
