Question

因此，我想使用邮递员发送多个数据（json）。例如，我有两个数据json。我想同时使用邮递员将该json发送到mongodb。但是我出错了

SyntaxError: Unexpected token , in JSON at position 168<br> and so on.

因此，我尝试将对象包装到数组中。我有一个错误

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.

我确定所有数据都已填满。

我的目标是要发送大量这样的数据json。不只是一两个。大概十个或更多，但是只发送一次。

我想发送到mongodb的示例json

{
  "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"
}

模式

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}
});

路线（后路线）

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});
  }
});

谢谢

Answer 1

很抱歉，如果您想到了这一点，但是可以在Postman中传递一个数组，然后将路由.forEach放在该数组的元素上以存储在数据库中。

如果您有时想发送单个对象，甚至可以设置条件以首先检查它是否为数组。

Answer 2

您将必须将JSON作为数组发送。

[{
  "title": "Asparagus",
  ...
}, {
  "title": "Green smoothie",
  ...
}]

然后您可以像这样访问它：

req.body.forEach(item => {
  // do something with item
})

使用邮递员将Node.js上的多个数据发送到mongodb
