To make a form-data request with Koa, you can use the formidable package along with the koa-bodyparser middleware. Here is an example:
- Install the dependencies:
1
|
npm install koa koa-bodyparser formidable |
- Create a Koa server and configure the body parser middleware:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
const Koa = require('koa');
const formidable = require('formidable');
const bodyParser = require('koa-bodyparser');
const app = new Koa();
app.use(bodyParser()); // Use the body parser middleware
// Define a POST endpoint to handle the form-data request
app.use(async (ctx, next) => {
if (ctx.url === '/upload' && ctx.method === 'POST') {
const form = new formidable.IncomingForm();
// Parse the form-data request
const fields = await new Promise((resolve, reject) => {
form.parse(ctx.req, (err, fields, files) => {
if (err) reject(err);
resolve(fields);
});
});
ctx.body = fields; // return the parsed form fields as the response
} else {
await next();
}
});
// Start the server
app.listen(3000, () => {
console.log('Server is running on http://localhost:3000');
});

- Send a form-data request to the server using a tool like cURL:
1
|
curl -X POST -F "username=johndoe" -F "[email protected]" -F "file=@/path/to/file.jpg" http://localhost:3000/upload |
In the example above, the server listens on port 3000 and expects a form-data request to the /upload endpoint. The code parses the form fields and returns them as the response body.
