使用 mongoose 连接到 Mlab

Question

嗨，我正在尝试建立一个简单的连接

mongoose.connect('mongodb://JFalcon:john2522@ds119476.mlab.com:19476/hidonshabat', {useMongoClient: true}, function(err){
    if(err) {
        console.log('Some problem with the connection ' +err);
    } else {
        console.log('The Mongoose connection is ready');
    }
})

如您所见，这是 url！请帮助我

        if(err) {
            console.log('Some problem with the connection ' +err);

Answer 2

var Mongoose=require("mongoose");
var dbURI='mongodb://JFalcon:john2522@ds119476.mlab.com:19476/hidonshabat';
Mangoose.connect(dbURI,function(err){    
    if(err){
    console.log('Some problem with the connection ' +err)   
    } 
    else {
    console.log('The Mongoose connection is ready')  
    }

})
module.exports={Mongoose};

Answer 3

mongoose.connect('mongodb://localhost:27017/myapp', **{useNewUrlParser: true}**);

来自官方文档：

useNewUrlParser - The underlying MongoDB driver has deprecated their current connection string parser. Because this is a major change, they added the useNewUrlParser flag to allow users to fall back to the old parser if they find a bug in the new parser. You should set useNewUrlParser: true unless that prevents you from connecting. Note that if you specify useNewUrlParser: true, you must specify a port in your connection string, like mongodb://localhost:27017/dbname. The new url parser does not support connection strings that do not have a port, like mongodb://localhost/dbname.
