渡槽-如何在没有后端用户ID的情况下保存客户端数据 [英] Aqueduct - How to save client data without the user ID in my backend

问题描述

当我不知道用户ID时如何为用户保存数据？我想将其保存在我的渡槽后端中，以便保护和查询当前用户数据？

How can I save data for a user when I don't know their user ID? I want to save it in my Aqueduct back end so I can protect and query current user data?

@Operation.post()
Future<Response> addData(@Bind.body(ignore: ['id']) Data newData) async {
  final query = Query<Data>(context)..values = newData;
  final insertData = await query.insert();
  return Response.ok(insertData);
}

推荐答案

渡槽自动生成用户ID创建新用户时。该ID与用户的登录凭据或访问令牌相关联。

Aqueduct automatically generates a user ID when you create a new user. That id is associated with the user's login credentials or access token.

在您的示例中，用户以数据模型传递了一些数据：

In your example here the user passed in some data in a Data model:

@Operation.post()
Future<Response> addData(@Bind.body(ignore: ['id']) Data newData) async {
  final query = Query<Data>(context)..values = newData;
  final insertData = await query.insert();
  return Response.ok(insertData);
}

问题是用户不知道自己的ID，因此在 newData 中丢失。

The problem is that the user didn't know their own ID so that is missing in newData.

假设您有路线受授权者保护，则您可以这样获得用户ID：

Assuming that you have the route protected with an Authorizer, then you can get the user ID like this:

final userID = request.authorization.ownerID;

因此您可以像这样使用它：

So you can use it like this:

@Operation.post()
Future<Response> addData(@Bind.body(ignore: ['id']) Data newData) async {

  final userID = request.authorization.ownerID;

  final query = Query<Data>(context)
    ..values.id = userId
    ..values.something = newData.something
    ..values.another = newData.another;

  final insertData = await query.insert();
  // if insert was successful then...
  return Response.ok(insertData);
}

顺便说一句，由于您将插入的数据返回给用户，将包含userId。但是，客户端不需要的。

By the way, since you are returning the inserted data to the user, it will include the userId with it. The client shouldn't need that, though.
