Node.js脚本未连接到localhost中的Mongodb数据库
在创建RESTAPI时，我有以下测试代码来运行mongodb和node.jsNode.js脚本未连接到localhost中的Mongodb数据库,node.js,mongodb,Node.js,Mongodb,在创建RESTAPI时，我有以下测试代码来运行mongodb和node.js MONGO.JS var mongoose = require("mongoose"); mongoose.connect('mongodb://localhost/smartRideDb'); // create instance of Schema var mongoSchema = mongoose.Schema; // create schema var userSchema = {
MONGO.JS
var mongoose = require("mongoose");
mongoose.connect('mongodb://localhost/smartRideDb');
// create instance of Schema
var mongoSchema = mongoose.Schema;
// create schema
var userSchema = {
"id" : String,
"email" : String,
"password" : String
};
// create model if not exists.
module.exports = mongoose.model('user',userSchema);
var mongoOp = require("./models/mongo");
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var router = express.Router();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({"extended" : false}));
app.use('/' , router);
var port = process.env.PORT || 3000;
/**

// Generic error handler used by all endpoints.
function handleError(res, reason, message, code)
{
console.log("ERROR: " + reason);
res.status(code || 500).json({"error": message});
}
/**

router.get("/",function(req,res)
{
res.json({"error" : false,"message" : "Hello World"});
});
//route() will allow you to use same path for different HTTP operation.
//So if you have same URL but with different HTTP OP such as POST,GET etc
//Then use route() to remove redundant code.
router.route("/users").get(function(req, res)
{
var response = {};
mongoOp.find({},function(err,data)
{
if(err)
{
response = {"error" : true,"message" : "Error fetching data"};
}
else
{
response = {"error" : false,"message" : data};
}
res.json(response);
});
});
app.listen(port);
console.log("Listening to PORT " + port);

为什么mongodb无法获取请在应用程序之前尝试调用与mongo的连接。听着，mongoose在默认情况下会打开一个连接池来处理请求
mongoose.connect('mongodb://localhost/dbname', function(err) {
if (err) throw err;
app.listen(port);
console.log("Listening to PORT " + port);
});
