Impossible to send x-www-form-urlencoded payload the fetch way

[Aareksio]

Hi! The following requests fails to send x-www-form-urlencoded payload:

import { URLSearchParams } from 'url';
import { $fetch, fetch } from 'ohmyfetch';

(async function main() {
  const body = new URLSearchParams({ test: 'true' });

  const responseA = await $fetch('https://httpbin.org/post', { method: 'POST', body });
  console.log(responseA);

  const responseB = await fetch('https://httpbin.org/post', { method: 'POST', body });
  console.log(await responseB.json());
})();

// $fetch
{
  args: {},
  data: '{}',
  files: {},
  form: {},
  headers: {
    Accept: 'application/json',
    'Accept-Encoding': 'gzip,deflate,br',
    'Content-Length': '2',
    'Content-Type': 'application/json',
    Host: 'httpbin.org',
    'User-Agent': 'node-fetch',
    'X-Amzn-Trace-Id': 'Root=1-61a56083-3dd9c60f2746207123123123'
  },
  json: {},
  origin: '123.123.123.123',
  url: 'https://httpbin.org/post'
}

// fetch
{
  args: {},
  data: '',
  files: {},
  form: { test: 'true' },
  headers: {
    Accept: '*/*',
    'Accept-Encoding': 'gzip,deflate,br',
    'Content-Length': '9',
    'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8',
    Host: 'httpbin.org',
    'User-Agent': 'node-fetch',
    'X-Amzn-Trace-Id': 'Root=1-61a56084-557df690674d50c123123123'
  },
  json: null,
  origin: '123.123.123.123',
  url: 'https://httpbin.org/post'
}

Why is this important? Fetch spec allows for passing URLSearchParams to indicate x-www-form-urlencoded payload. node-fetch follows the spec. ohmyfetch does not, despite sending the user to node-fetch documentation for references.

Why it fails? Probably typeof (new URLSearchParams) === 'object' here

Hi @Aareksio. This issue should be fixed on 0.4.9 (4adb3bc)
