我正在尝试连接到cloud.mongodb.com。但是运行时出现错误。
const express = require('express');
const cors = require('cors');
const bodyParser = require("body-parser");
const logger = require('morgan');
const Data = require("./data");
const mongoose = require("mongoose");
const API_PORT = 5000;
/// database config
const DB_KEY = "mongodb+srv://twituet:<mypassWord>@cluster0-ziifr.mongodb.net/test?retryWrites=true";
mongoose
.connect(
DB_KEY, {useNewUrlParser: true}
)
.then(() => {
console.log("Connected to database!");
})
.catch((error) => {
console.log("Connection failed!");
console.log(error);
});
但是我遇到错误：
