Question

当使用Node.js插入MongoDB时，Mongoose模式不允许我使用@ sign in键。例如：

var blogSchema = new Schema({
@context : Object //error illegal token
@id : String // illegal token


}, {strict: false});

我尝试使用像这样的unicode字符键：

"\u0040context" = Object // ignored unicode, inserted as context
 "\x40context" = Object // ignored unicode, inserted as context
 \x40context = Object // illegal token

还使用此链接（第一种方式）以正常方式尝试，仍然无法使用@定义键： http://blog.modulus.io/mongodb-tutorial

我的目的是使用JSON-LD格式创建文档，这需要在键中使用@符号。怎么做到这一点？以下是我寻求解决方案的类似链接：

您可以在引号之间直接使用@，例如"@field"：

"use strict";

var mongoose = require('./node_modules/mongoose');

var Schema = mongoose.Schema;
var db = mongoose.connection;

var itemSchema = new Schema({
    "@field": {
        type: String,
        required: true
    },
    "@field2": {
        type: String,
        required: true
    }
});
var Items = mongoose.model('Items', itemSchema);

var db = mongoose.connect('localhost', 'testDB');

Items.create({ "@field": "value", "@field2": "value" }, function(err, doc) {
    console.log("created");
    if (err)
        console.log(err);
    else {
        console.log(doc);
    }
    db.disconnect();
});
