node.js - 使用猫鼬检索数组中的对象信息
问题描述
我正在使用 node、express、typescript 和 mongoose 制作 API Rest。我有一个返回此结果的方法 GET:
{
"success": true,
"status": 200,
"message": "categories listed",
"data": [
{
"_id": "612650e55fe1ce0de138e2af",
"products": [
{
"_id": "612650e55fe1ce0de138e2b0",
"productID": {
"reviews": [
"611e61ba8cb43f7454787ebb",
"611e62008cb43f7454787ebc"
],
"_id": "610b18f3e2244a187b36f2d7",
"title": "PS4",
"description": "La mejor consola del mercado del mundo, mundial",
"photo": "https://amazon-clone-jparrot.s3.amazonaws.com/1628123519052",
"price": 400,
"stockQuantity": 23,
"__v": 0,
"category": "60fc6454b68717acc239cc6a",
"owner": "610b9ed8763da4308223aae0",
"averageRating": null,
"id": "610b18f3e2244a187b36f2d7"
},
"quantity": 1,
"price": 400
}
],
"owner": {
"_id": "611d2d39dfcc705972c1ccb8",
"name": "Jaume",
"email": "jaumeparrot2@gmail.com",
"password": "$2a$10$Rv9Rzrff6578feCdDjyeKuarKCSHYRqKp5n5wTi2IWtcLBOupvPgu",
"__v": 0,
"address": "611e9ccdf47c7a7a9cb1d5d9"
},
"estimatedDelivery": "Wednesday September 1st",
"__v": 0
}
]
}
问题是我需要检索对象“所有者”,即我需要恢复这个json:
{
"success": true,
"status": 200,
"message": "categories listed",
"data": [
{
"_id": "612650e55fe1ce0de138e2af",
"products": [
{
"_id": "612650e55fe1ce0de138e2b0",
"productID": {
"reviews": [
"611e61ba8cb43f7454787ebb",
"611e62008cb43f7454787ebc"
],
"_id": "610b18f3e2244a187b36f2d7",
"title": "PS4",
"description": "La mejor consola del mercado del mundo, mundial",
"photo": "https://amazon-clone-jparrot.s3.amazonaws.com/1628123519052",
"price": 400,
"stockQuantity": 23,
"__v": 0,
"category": "60fc6454b68717acc239cc6a",
"owner": {
"_id": "611d2d39dfcc705972c1ccb8",
"name": "Jaume",
"about": "My na is Jaume",
"__v": 0
},
"averageRating": null,
"id": "610b18f3e2244a187b36f2d7"
},
"quantity": 1,
"price": 400
}
],
"owner": {
"_id": "611d2d39dfcc705972c1ccb8",
"name": "Jaume",
"email": "jaumeparrot2@gmail.com",
"password": "$2a$10$Rv9Rzrff6578feCdDjyeKuarKCSHYRqKp5n5wTi2IWtcLBOupvPgu",
"__v": 0,
"address": "611e9ccdf47c7a7a9cb1d5d9"
},
"estimatedDelivery": "Wednesday September 1st",
"__v": 0
}
]
}
为了生成这个 JSON,我使用这个方法: https ://github.com/jparrot92/amazon-clone-back/blob/master/src/controllers/order.ts
解决方案
要检索您应该使用data.owner
. 这将提供owner
详细信息作为对象。
