无法通过节点Rest应用上的猫鼬连接到mongodb-altas，连接失败：“ UnhandledPromiseRejectionWarning：错误：连接EACCES”

Question

我在mongodb-altas上创建了一个新集群，选择Aws-孟买地区，创建用户，允许从任何地方访问，复制“节点3或更高版本”的连接字符串。当尝试从我的节点Express Rest应用建立连接时，出现以下异常。

const mongoose=require('mongoose');
mongoose
.connect(
"mongodb+srv://anky7493:<MYPASSWORDISHERE>@dreamjob- 
i84sb.mongodb.net/test?retryWrites=true"
)
.then(() => {
console.log("Connected to database!");
})
.catch((error) => {
console.log("Connection failed!");
console.log(error);
});

运行应用程序> nodemon索引，以下是错误

[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `node index index.js`
(node:9504) DeprecationWarning: current URL string parser is deprecated,         
and will be removed in a future version. To use the new parser, pass     
option { useNewUrlParser: true } to MongoClient.connect.
now listening for request !

谁能告诉我如何与mongo-altas建立联系。 预先感谢。

Answer 1

您是否尝试使用{useNewUrlParser：true}选项，就像它说的那样？

const mongoose=require('mongoose');
mongoose
.connect(
"mongodb+srv://anky7493:<MYPASSWORDISHERE>@dreamjob- 
i84sb.mongodb.net/test?retryWrites=true"
, { useNewUrlParser: true })
.then(() => {
console.log("Connected to database!");
})
.catch((error) => {
console.log("Connection failed!");
console.log(error);
});
