如何从一个大型 JSON 对象中解析单个 JSON 对象

Question

我正在尝试在一个大型 JSON 对象中解析多个 JSON 对象。现在它将整个 JSON 对象存储为一个对象，我需要将它们解析为单独的对象以存储在 mongodb 中。这是我的代码。

获取订单请求

WooCommerce.get('orders', function(err, data, res){
console.log(res);
var parsedOrders = JSON.parse(res);
var step;
for(step = 0; step < parsedOrders.length; step++){
    var emagispaceOrders = new Orders({orders: step});
    emagispaceOrders.save();
}    
});

用于在猫鼬模式中存储 JSON 对象的模型

var Schema = mongoose.Schema;



var orderSchema = new Schema({
orders: {type: Object}
});

var Orders = mongoose.model('Orders', orderSchema);

module.exports = Orders;

它保存订单对象，但不保存 JSON 对象中的数据。所以基本上总结一下，我的 mongodb 填充了专门的 8 个空对象，这些对象只包含下面显示的内容，而不是 JSON 对象发送的实际数据。

{ "_id" : ObjectId("58d93d05fdcd524224469604"), "orders" : 0, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd524224469606"), "orders" : 2, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd524224469605"), "orders" : 1, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd524224469607"), "orders" : 3, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd524224469608"), "orders" : 4, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd524224469609"), "orders" : 5, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd52422446960a"), "orders" : 6, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd52422446960b"), "orders" : 7, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd52422446960d"), "orders" : 9, "__v" : 0 }
{ "_id" : ObjectId("58d93d05fdcd52422446960c"), "orders" : 8, "__v" : 0 }

它应该包含通过 woocommerce 提交的完整订单，其中包含订单 ID、总计、客户名称等。

任何帮助将不胜感激。

猫鼬模式

var Schema = mongoose.Schema;



var orderSchema = new Schema({
id: {type: Number},
parent_id: {type: Number},
status: {type: String},
number: {type: Number},
customer_id: {type: Number},
shipping_total: {type: String},
total: {type: String},
total_tax: {type: String}
});

var Orders = mongoose.model('Orders', orderSchema);

module.exports = Orders;

这是一个 JSON 响应对象。我收到的响应包含其中的 35 个，我需要从包含较小订单对象的主/大 JSON 对象中解析这些对象。

Answer 1

对象不是valid Mongoose schema types，这意味着您需要提前知道您的订单对象将采用什么形状，否则 Mongoose 将不会保存它们。

编辑

针对您的编辑，我刚刚注意到您没有尝试保存正确的对象。你在做

Orders({orders: step});

其中step 是一个索引，因此您实际上是在保存一个数字。你想做的是

Orders({orders: parsedOrders[step]});

这将引用正确的顺序。

实际上，您的架构在原始问题和编辑中有所不同。无论哪种方式，请记住，要获得订单，您需要通过parsedOrders[step] 引用它，其中step 是一个索引。
