I'm new to Koa and i encountered a problem that I didnt get when i used epxress.
here is my code :
const koa = require("koa");
const koaRouter = require("koa-router");
const app = new koa();
const router = new koaRouter();
const cors = require('koa-cors');
const bodyParser = require("body-parser");
const port = 8080;
app.use(router.routes()).use(router.allowedMethods());
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json());
app.listen(port, () => {
console.log("server koa started " + port);
});
router.get("/id/:id", async (ctx) => {
const id = ctx.params.id;
console.log("id was " + id);
ctx.body = {
"id": id
}
});
router.get("/", async (ctx) => {
ctx.body = {
"message": "hello"
}
});
when I want to call this from my webserver i got this :
Access to fetch at 'http://localhost:8080/id/azerty' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
What can I do to solve this problem ? Thanks
see here Koa cors module
const Koa = require('koa');
const cors = require('@koa/cors');
const app = new Koa();
app.use(cors());
You're not using the module in your code.
