node.js - NodeJS API : Find a document into a collection by "Id" property , 在 Mongodb 中默认不是 "_id"

Question

我想通过模式中的属性“id”检索文档，而不是使用 Mongodb 默认的“_id”。

当我这样请求时，我希望得到回复: https://sample-accounts-api.herokuapp.com/accounts/2

{
        attributes: {
          id: 2,
          user_id: 2,
          name: "Bカード",
          balance: 200
        }
      }

这是我的帐户模型:

var AccountSchema = new mongoose.Schema({
        id: {type: Number},
        user_id: {type: Number, ref: 'User'},
        name: String,
        balance: Number
});

这是我的 Controller API:

const Account = require('../model/account');
exports.findOne = (req,res) => {
    Account
    .findById(???)
    .then(account => {
        if(!account) {
            return res.status(404).send({
                message: "Account not found with ID " 
            });
        }
        res.send(account);
    })
    .catch(err => {
        return res.status(505).send({
            message: "Something wrong retrieving account with Id "
        });
    })
}

    exports.findOne = (req,res) => {
    Account
    .findOne({'attributes.id':req.params.id})
    .then(account => {
        if(!account) {
            return res.status(404).send({
                message: "Account not found with ID " 
            });
        }
        res.send(account);
    })
    .catch(err => {
        return res.status(505).send({
            message: "Something wrong retrieving account with Id "
        });
    })
}

使用attributes.id并将其映射到您的req.params.id。
