[英]Send multiple data on nodejs to mongodb using postman
所以,我想使用 postman 發送多個數據(json)。 例如,我有兩個數據 json。 我想同時使用 postman 將 json 發送到 mongodb 。 但我有一個錯誤
SyntaxError: Unexpected token , in JSON at position 168<br> and so on.
所以我嘗試將 object 包裝到數組中。 我得到了一個錯誤
Products validation failed: title: Path `title` is required., type: Path `type` is required., description: Path `description` is required., filename: Path `filename` is required., price: Path `price` is required., rating: Path `rating` is required.
我確定所有數據都已填滿。
我的目標是像這樣發送大量數據 json 。 不只是一兩個。 喜歡十個或更多,但只發送一次。
示例 json 我想發送到 mongodb
{
"title": "Asparagus",
"type": "vegetable",
"description": "Asparagus with ham on the wooden table",
"filename": "2.jpg",
"price": "18.95",
"rating": "3"
}, {
"title": "Green smoothie",
"type": "dairy",
"description": "Glass of green smoothie with quail egg's yolk, served with cocktail tube, green apple and baby spinach leaves over tin surface.",
"filename": "3.jpg",
"price": "17.68",
"rating": "4"
}
圖式
const productSchema = new mongoose.Schema({
title: {type: String, required: true},
type: {type: String, required: true},
description: {type: String, required: true},
filename: {type: String, required: true},
price: {type: Number, required: true},
rating: {type: Number, required: true},
date: {type: Date, default: Date.now}
});
路線(郵政路線)
const Product = require('../models/product.js');
routes.post('/', async (req, res) => {
const product = new Product({
title: req.body.title,
type: req.body.type,
description: req.body.description,
filename: req.body.filename,
price: req.body.price,
rating: req.body.rating
});
try {
const new_product = await product.save();
return res.status(201).json(new_product);
}catch(err){
return res.status(400).json({error: err.message});
}
});
謝謝
抱歉,如果您想到了這一點,但是可以在 Postman 中傳遞一個數組,然后將您的 route.forEach 放在數組的元素上以存儲在數據庫中。
如果您有時想要發送單個 object,您甚至可以設置一個條件來首先檢查它是否是一個數組。
您必須將 JSON 作為數組發送。
[{
"title": "Asparagus",
...
}, {
"title": "Green smoothie",
...
}]
然后你可以像這樣訪問它:
req.body.forEach(item => {
// do something with item
})
