当我试图为我的mongodb创建一个猫鼬模型时。我正在尝试for-in循环遍历响应数据并将其保存在我的mongodb中。

模型/订单架构：

var mongoose = require('mongoose'),
bcrypt = require('bcryptjs'),
config = require('../config/database');


var Schema = mongoose.Schema;

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

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

module.exports = Orders;

woocommerce认证：

WooCommerceAPI = require('woocommerce-api');

var WooCommerce = new WooCommerceAPI({
url: 'https://www.example.com',
consumerKey: 'ck_example',
consumerSecret: 'cs_example',
wpAPI: true,
version: 'wc/v1',
queryStringAuth: true
})

获取请求并保存到mongoose架构：

WooCommerce.get('orders', function(err, data, res){
console.log(res);
for(var orders in res){
    var O = new Orders(orders);
    O.save();
}
});

res是一个JSON对象。

另一个注意事项：由于某种原因，它仍然保存到我的数据库中，但它几乎就像是在无限循环中，因为它比我预期的节省了更多的数据。我没有使用for-in循环的经验，但认为这是解决这个问题的最佳方法。如果您对我出错的地方有任何见解，我将非常感激！

我通过将模型的规范添加到我的获取请求来修复此问题。

WooCommerce.get('orders', function(err, data, res){
console.log(res);
for(var orders in res){
var O = new Orders({orders: wooorders});
O.save();
}
});

TypeError：无法使用'in'运算符在{}
