Question

mongoose.connect(DB，｛useNewUrlParser:true，useCreateIndex:true，useUnifiedTopology:true，useFindAndModify：false})则(((=>{console.log(connection successful(；}).catch((err(=>console.log(no connection((；

Answer 1

看起来你传递了错误的dbURL，你的url应该像这个

mongodb+srv://<username>:<password>@<cluster_name>.<dbid>.mongodb.net/<Database_Name>?retryWrites=true&w=majority

试试这个

const dbURL = Your mongoDb url
mongoose.connect(dbURI, { useNewUrlParser: true, useUnifiedTopology: true })
.then(result => console.log('connected to db'))
.catch(err => console.log(err));
