Artillery 出现错误。Deno 服务器上的 ECONNREFUSED

Question

我有一个简单的 Deno 应用程序，它使用 Express 和 Mongodb。 这个应用程序运行完美，当我使用 Postman 发送请求时可以正确插入记录。

但是，当我使用 Artillery 运行负载测试时，artillery 会给出如下错误：

Warning: multiple batches of metrics for period 1696402250000 2023-10-04T06:50:50.000Z
All VUs finished. Total time: 10 seconds

我的索引.ts：

import { MongoClient } from "npm:mongodb";
import express from "npm:express";

const url = "mongodb://127.0.0.1:27017/some-db";
const client = new MongoClient(url);
client.connect().then(() => console.log("Connected successfully to server")).catch(console.log("Error connecting to server"));
const db = client.db("some-db");
const collection = db.collection("users");

const app = express();
app.use(express.json());

app.post('/', async (req, res) => {
  const savedUser = await collection.insertOne(req.body);

  return res.send(200);
});

app.listen(3000, () => console.log('Server is running on 3000'));

            surname: "Doe"
            birthday: "1990-01-01"

有什么想法吗？预先感谢。

Answer 1

Artillery 的一些用户过去曾报告过此问题此处。

尝试将目标从

http://localhost:3000

更改为

http://127.0.0.1:3000

，应该可以解决问题。
