nginx conf example

[willin]

can you give me a config example of nginx?

server {
        listen 80;
        server_name *.example.com;
  
         location / {
                 proxy_pass http://127.0.0.1:3000/;
                 proxy_redirect off;
         }
}

can this one work perfectly?

You need to pass Host field to nodejs, koa-subdomain will select different route based on the Host field.

[willin]

server {
        listen 80;
        server_name *.example.com;
  
         proxy_set_header Host $http_host;
         location / {
                 proxy_pass http://127.0.0.1:3000/;
                 proxy_redirect off;
         }
}

like this?

Almost that, you can try to debug.

const Koa = require('koa');
const Subdomain = require('koa-subdomain');
const router = require('koa-route');

const app = new Koa();
const subdomain = new Subdomain();

subdomain.use('*', router.get('/', async (ctx) => {
  ctx.body = ctx.subdomains;
}));

app.use(subdomain.routes());

app.listen(4123);

sub.example.com can visit.

sub.sub.example.com cannot visit.

[keenwon]

sub.sub.example.com will match *.sub.example.com. Currently, * only match 1 domain offset.

最新版本 koa-route

不再需要

new Router()

另外我还有一个疑问，可能你能帮得上，能加个 QQ 微信么

[keenwon]

我突然发现你写的是koa-route，而我一直用的是koa-router，对于koa-router，你不new也可以，他自己会处理的：
