API(NodeJS + Express)中未顯示數據

[英]Data not showing in the API (NodeJS + Express)

我正在為想要通過輸入餐廳名稱檢索餐廳數據的餐廳開發示例 API。 Controller,Model & 路由器已設置,但如果我將其加載到 Postman 數據不會出現。 請分享一些想法。

Controller:(restaurant.js)

const restaurants = require('../Models/restaurantData');
exports.getRestaurantName = (req, res) => {
    const Name = req.params.name;    
    restaurants.find({
        name: Name
    }).then(result => {
        res.status(200).json({
            message: "Restaurant Data",
            restaurants: result[0]
        });
    }).catch(error => {
        res.status(500).json({
            message: error
        });
    });
}

Model: (restaurantData.js)

const mongoose = require('mongoose');

const Schema = mongoose.Schema;

const restaurantSchema = new Schema({
    _id: {
        type: Number,
        required: true
    },
    name: {
        type: String,
        required: true
    },
    city_name:{
        type: String,
        required: true
    },
    city_id: {
        type: String,
        required: true
    },
    location_id: {
        type: Number,
        required: true
    },
    area: {
        type: Number,
        required: true
    },
    locality:{
        type: String,
        required: true
    },
    thumb: {
        type: String,
        required: true
    },
    cost:{
        type: Number,
        required: true
    },
    address:{
        type: String,
        required: true
    },
    mealtype:{
        type: Number,
        required: true
    },
    name:{
        type: String,
            required: true
        },    
    cuisine:{
        type: Number,
        required: true
    },
    type:{
        type: Array,
        required: true
    },
    Cuisine:{
        type: Array,
        required: true
    }
});

module.exports = mongoose.model('restaurantData', restaurantSchema, 'restaurantData');

路由器:

const express = require('express');
const restaurantController = require('../Controllers/restaurant');

const router = express.Router();

router.get('/restaurantData/:name',restaurantController.getRestaurantName);

module.exports = router;

更改以下內容,我希望它會起作用。 在餐廳 Model 中,刪除此:

module.exports = mongoose.model(  "restaurantData",  restaurantSchema,  "restaurantData");

並添加:

const Restaurant = mongoose.model("restaurantData", restaurantSchema);
module.exports = { Restaurant };

在您的餐廳 controller 中,將導入腳本更改為:

const { Restaurant } = require("../Models/restaurantData");

方法將是:

Restaurant.find({
    name: Name,
  })

根據需要更改變量和文件名。

如果是,您是否添加了網絡訪問權限,然后使用Model.create(req.body(err,data)={ res.send(data); })

我認為問題可能出在從架構中創建 model 時

module.exports = mongoose.model('restrauntData', restaurantSchema);   

使用上面的而不是

module.exports = mongoose.model(  "restaurantData",  restaurantSchema,  "restaurantData");

那么它應該可以正常工作。
