Koa router not seeing post body?

Question

Testing koa.js and fetch on the client side. I am trying to post some data on the server. I am getting undefined with the code below. I am unsure why.

I have inspected this, this.request, this.req, etc and I cannot find my data from the client req?

Server

import koaRouter from 'koa-router'

// Post route
router.post('/api/upload', function *(next) {
  console.log('UPLOAD WORKS', this.req.body)
  this.status = 200
})

app
  .use(bodyParser())
  .use(router.routes())
  .use(router.allowedMethods())

The console gives me undefined.

Client

fetch('/api/upload', {
  method: 'post',
  body: 'Hello'
}).then(function(response) {
  console.log(response)
}).catch(function(err) {
  // Error :(
});

I came across that. I was still missing my data. I am thinking its because of fetch() maybe. — Michael Joseph Aubry, Jul 22 '16 at 08:21

Ok, on your client fetch you should consider to use a 'FormData' object to wrap your string. [here](http://stackoverflow.com/questions/29775797/fetch-post-json-data) an example. — Mario Santini, Jul 22 '16 at 08:30

You should change your client fatch to use a 'FormData' object to wrap the string.

var formData = new FormData();
formData.append('json', 'Hello');

fetch('/api/upload', {
  method: 'post',
  body: formData
}).then(function(response) {
  console.log(response)
}).catch(function(err) {
  // Error :(
});
