将通用类型作为funciton中的参数传递

Question

我正在尝试使用AWS数据存储设置CRUD服务，以更加整理我的代码库，并在需要时切换后端，我很难弄清楚如何通过类型（而不是变量）传递给datastore的功能。我现在所拥有的如下：

import { DataStore } from "@aws-amplify/datastore";

export default class CrudService<T> {
  constructor() {}

  public static async post(data: any): Promise<any> {
    return await DataStore.save(data);
  }

  public static async get(id: string): Promise<any> {
    return await DataStore.query(T, id); // This doesn't work...
  }

  public static async put(data: any): Promise<any> {
    return await DataStore.save(data);
  }

  public static async remove(id: string): Promise<any> {
    return await DataStore.delete(T, id); // This too doesn't work...
  }
}

但是，这有效

  import { UserModel } from "../models";

  public static async read(id: string): Promise<any> {
    return await DataStore.query(UserModel, id);
  }

，但是我想让这个crudservice能够与任何具有其各自型号类型的API一起使用，以便当我想使用它时，我会这样使用它：

import { IApi } from "../interfaces";
import { UserModel } from "../models";
import { CrudService } from "../services";

export default class UsersAPI extends CrudService<UserModel> implements IApi<UserModel> {  
  public create = async (data: UserModel): Promise<UserModel> => {
    return await UsersAPI.post(data)
    // return await DataStore.save(data);
  };

  public read = async (id: string): Promise<UserModel[]> => {
    return await UsersAPI.get(id);
    // return await DataStore.query(UserModel, id);
  };

  public update = async (data: UserModel): Promise<UserModel> => {
    return await UsersAPI.put(data);
    // return await DataStore.save(data);
  };

  public delete = async (id: string): Promise<any> => {
    return await UsersAPI.remove(id);
    // return await DataStore.delete(UserModel, id);
  };
}
