Question

这是我的Json对象，用于存储在数据库中的产品。这个json对象还存储了另一个带有图像的json对象 1.问题：这是在数据库中存储产品数据的正确方法，还是应该单独存储图像？ 2.question：这个json对象的格式是否正确，我对sub json“images”特别感兴趣？ 3.问题：如果子Json“images”会有一些json索引数组，其中index将是图像的位置

，JSON对象应该怎么样？

{
  "id_product": "1000",
  "name": "Rippin Unions",
  "description": "Vel aut sed neque enim illum mollitia. Molestias aperiam qui dolorem qui est. Dolore cumque dolore formatedtempore ipsum. Veniam molestiae laudantium voluptates numquam.",
  "date_c": "2015-12-31 02:06:32",
  "date_u": null,
  "id_category": "46",
  "id_user": "123",
  "alias": "rippin-unions",
  "active": "1",
  "images": "[
              {thumbImage:"http://lorempixel.com/250/150/?27403",image:"http://lorempixel.com/1024/768/?28526",position:4},
              {thumbImage:"http://lorempixel.com/250/150/?25207",image:"http://lorempixel.com/1024/768/?73566",position:1},
              {thumbImage:"http://lorempixel.com/250/150/?26960",image:"http://lorempixel.com/1024/768/?72686",position:0},
              {thumbImage:"http://lorempixel.com/250/150/?25168",image:"http://lorempixel.com/1024/768/?22297",position:2},
              {thumbImage:"http://lorempixel.com/250/150/?94897",image:"http://lorempixel.com/1024/768/?94418",position:3}
             ]"
   }

我问这个是因为目前我在打印JSON数据时遇到问题。我所能做的就是拨打products[0].images，但如果我尝试选择第一张拇指图片，我就会失败。我尝试了很多变化，没有任何工作

如果您还有其他问题，请告诉我，我会提供。
提前致谢

Answer 1

当您想要测试json结构时，您的JSON似乎无效，this这样的网站非常有帮助。

编辑：在您的情况下，有效的JSON将是：

{ "id_product": "1000", "name": "Rippin Unions", "description": "Vel aut sed neque enim illum mollitia. Molestias aperiam qui dolorem qui est. Dolore cumque dolore formatedtempore ipsum. Veniam molestiae laudantium voluptates numquam.", "date_c": "2015-12-31 02:06:32", "date_u": "null", "id_category": "46", "id_user": "123", "alias": "rippin-unions", "active": "1", "images": "[{'thumbImage': 'http://lorempixel.com/250/150/?27403\','image': 'http://lorempixel.com/1024/768/?28526\','position': '4'},{'thumbImage': 'http://lorempixel.com/250/150/?25207\','image':'http: //lorempixel.com/1024/768/?73566\','position':'1'}]" }

我建议您阅读本文tutsplus

在jsonlint复制并通过以下内容进行验证，

 {
    "id_product": 1000,
    "name": "Rippin Unions",
    "description": "Vel aut sed neque enim illum mollitia. Molestias aperiam qui dolorem qui est. Dolore cumque dolore formatedtempore ipsum. Veniam molestiae laudantium voluptates numquam.",
    "date_c": "2015-12-31 02:06:32",
    "date_u": null,
    "id_category": 46,
    "id_user": 123,
    "alias": "rippin-unions",
    "active": 1,
    "images": [{
        "thumbImage": "http://lorempixel.com/250/150/?27403",
        "image": "http://lorempixel.com/1024/768/?28526",
        "position": 4
    }, {
        "thumbImage": "http://lorempixel.com/250/150/?25207",
        "image": "http://lorempixel.com/1024/768/?73566",
        "position": 1
    }, {
        "thumbImage": "http://lorempixel.com/250/150/?26960",
        "image": "http://lorempixel.com/1024/768/?72686",
        "position": 0
    }, {
        "thumbImage": "http://lorempixel.com/250/150/?25168",
        "image": "http://lorempixel.com/1024/768/?22297",
        "position": 2
    }, {
        "thumbImage": "http://lorempixel.com/250/150/?94897",
        "image": "http://lorempixel.com/1024/768/?94418",
        "position": 3
    }]
}
