在 Mongodb 中连接 ECONNREFUSED 127.0.0.1:27017

Question

您好，我是 MongoDB 的新手。我正在尝试使用 'mongodb://localhost:27017' 连接到 MongoDb 但未连接。但是我尝试使用它正在运行的 MongoDb Compass 和 mongosh shell 命令输入。 错误代码是

node app.js
node:internal/process/promises:288
triggerUncaughtException(err, true /* fromPromise */);
            ^

将 localhost 更改为 0.0.0.0。在源代码中。

const url = "mongodb://localhost:27017/"; const client = new MongoClient(url);

到

const url = "mongodb://0.0.0.0:27017/"; const client = new MongoClient(url);
