我使用express来使服务听取使用mongoose从mogno db获取数据的请求。我的服务器index.js看起来像这样。
var express = require("express");
var contacts = require("./contact");
var app = express();
app.configure(function() {
app.use(express.bodyParser());
});
app.get("/", contacts.index);
app.get('/contacts', contacts.index);
app.listen(1222, "127.0.0.1");
我从数据库中获取数据的contact.js文件结构如下：
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/mukund');
var Schema = mongoose.Schema;
var ContactSchema = new Schema({
username: { type: String }
});
var ContactModel = mongoose.model('Contact', ContactSchema);
exports.index = function(req, res) {
return ContactModel.find(function(err, contacts) {
if (!err) {
res.jsonp(contacts);
} else {
console.log(err);
}
});
}
问题是我有一个转储的mongo数据库，我想从转储的数据库中获取数据。但我不知道如何在没有我自己的模型的情况下获取数据。任何人都可以建议我使用mongoose获取数据的方法，而不知道模型。
我的数据的示例行如下所示：
