问题

我正在使用MacOS。这是我的Fastify代码：

  1. const fastify = require('fastify')({ logger: true })
  3. fastify.get('/ping', (req, reply) => {
  4.      reply.send({
  5.         pong: "pong"
  6.     })
  7. })
  9. const start = () => {
  10.     try {
  11.         fastify.listen({ port: 8895 })
  12.     } catch (e) {
  13.         fastify.log.error(e)
  14.         process.exit(1)
  15.     }
  16. }
  18. start()

它正在Docker容器中运行：

  1. version: '3'
  2. services:
  3.   node-app:
  4.     build: .
  5.     ports:
  6.       - "8895:8895"

这是我的Dockerfile：

  1. FROM node:latest
  2. COPY *.json ./
  3. COPY *.js ./
  4. RUN npm install
  5. CMD ["npm", "run", "start"]

这是我运行的命令：

  1. docker-compose down && docker-compose up --build

一切都在容器内正常工作。我也可以在容器内使用curl，Fastify返回状态码200。但从我的主机请求http://localhost:8895时，出现以下错误：

  1. This page isn’t working
  2. 127.0.0.1 didn’t send any data.
  3. ERR_EMPTY_RESPONSE

问题出在哪里？

I am working with MacOs. This is my fastify code

  1. const fastify = require('fastify')({ logger: true })
  3. fastify.get('/ping', (req, reply) => {
  4.      reply.send({
  5.         pong: "pong"
  6.     })
  7. })
  9. const start = () => {
  10.     try {
  11.         fastify.listen({ port: 8895 })
  12.     } catch (e) {
  13.         fastify.log.error(e)
  14.         process.exit(1)
  15.     }
  16. }
  18. start()

It is running inside docker container:

  1. version: '3'
  2. services:
  3.   node-app:
  4.     build: .
  5.     ports:
  6.       - "8895:8895"

This is my Dockerfile

  1. FROM node:latest
  2. COPY *.json ./
  3. COPY *.js ./
  4. RUN npm install
  5. CMD ["npm", "run", "start"]

This is the command I run to work:

> docker-compose down && docker-compose up --build

Everything is working inside the container. I can make also curl inside the container and fastify returns 200. But from my host, requesting http://localhost:8895, I am getting:

  1. This page isn’t working
  2. 127.0.0.1 didn’t send any data.
  3. ERR_EMPTY_RESPONSE

What's wrong?

得分: 2

你需要在listen上添加host选项：

  • 参考链接：https://fastify.dev/docs/latest/Reference/Server/#listentextresolver
  1. const start = () => {
  2.     try {
  3.         fastify.listen({ host: '0.0.0.0', port: 8895 })
  4.     } catch (e) {
  5.         fastify.log.error(e)
  6.         process.exit(1)
  7.     }
  8. }

与expressjs相比，这是一个“默认安全”的选项。

英文:

You need to add the host option on the listen:

  1. const start = () => {
  2.     try {
  3.         fastify.listen({ host: '0.0.0.0', port: 8895 })
  4.     } catch (e) {
  5.         fastify.log.error(e)
  6.         process.exit(1)
  7.     }
  8. }

This is a "security by default" option compared to expressjs.
