Question

我正在尝试通过服务器连接到猫鼬，但没有成功。

我已经尝试将其放入try catch块中，但是它说db.close或client.close不是函数。尝试连接时，出现错误“未处理的承诺拒绝警告”。

如果有人可以帮助我，我将很高兴

const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
const client = mongoose.connect('mongodb://localhost:27017/customercli', { 
useNewUrlParser: true });




// import the model
const Customer = require('./models/customer');


// Add customer
const addCustomer = (customer) => {
    Customer.create(customer).then(customer => {
        console.info("New Customer Added");
        client.close();
    });
}



// Find customer
const findCustomer = (name) => {
    //Make this case insensitive
    const search = new RegExp(name, 'i') // here lowercase i made it 
insensitive
    Customer.find({$or: [{firstname: search}, {lastname: search}]})
    .then(customer => {
        console.log(customer);
        console.log(`${customer.length} matches`);
        client.close();

    });
} 


//Export all methods
module.exports = {
    addCustomer,
    findCustomer
}

我自己找到了解决方法。通过我的服务器与猫鼬的连接未关闭。所以我用db.close()取代了mongoose.connection.close()，效果很好。
