Deno Uncaught Error: No such host is known. (os error 11001)

Question

我尝试使用 https://deno.land/x/mongo@v0.21.2 框架将 MongoDB Atlas 连接到我的 Deno 应用程序。我尝试了以下代码 运行 我的应用程序。但是我得到一个错误 No such host is known. (os error 11001) 这里出了什么问题

Error

error: Uncaught Error: No such host is known. (os error 11001)
    at unwrapResponse (rt_dispatch_json.js:24:13)
    at sendAsync (rt_dispatch_json.js:75:12)
    at async Object.connect (rt_net.js:221:13)
    at async MongoClient.connect (client.ts:41:14)
    at async mongodb.ts:33:1

Mongodb.ts File

import { MongoClient } from "https://deno.land/x/mongo@v0.21.0/mod.ts";
    
    const client1 = new MongoClient();
    await client1.connect("mongodb+srv://user1:MYPASSWORD@cluster0.hmdnu.mongodb.net/TestingDB?retryWrites=true&w=majority");
    
    const db = client1.database("TestingDB");
    
    export default db;

我用这个命令 运行 我的服务器

deno run --allow-net --allow-write --allow-read  --allow-plugin --unstable server.ts

解决了这个问题

按照以下步骤解决此问题

    import { MongoClient } from "https://deno.land/x/mongo@v0.21.0/mod.ts";
    
    const client1 = new MongoClient();
    
    await client.connect({
    db: "<db>",
    tls: true,
    servers: [
      { 
        host: "<host>",
        port: 27017,
      },
    ],
    credential: {
      username: "<user>",
      password: "<password>",
      db: "<db>",
      mechanism: "SCRAM-SHA-1",
    },
  });
    
 const db = client1.database("TestingDB");
    
 export default db;
