这是我的编码文件:
服务器文件
密钥文件
我只是使用mongodb,node和reactjs创建到mlab的连接。我正在使用mongo db版本4。

问题出在您的钥匙上。尝试使用:
module.exports= {
mongoURI : "your-uri-string",
options:{key:value}
}
并使用以下键:
mongoose.connect(db.mongoURI,options);

MongoDB地图集的一个非常常见的错误。最好还是遵循此程序
安装Mongo DB罗盘
使用默认设置
主机名:本地主机和端口27017
mongoose.connect('mongodb:// localhost / projectname') .then(()=> console.log('mongo db working')) .catch(err => console.log('ERROR is',err))
