Attempting to send POST request to API with JavaScript function-CodePudding

I am attempting to make an api get request using JS's built in XMLHttpRequest system. I am not sure why this function fails to work.

function updateStats(username){
  const request = new XMLHttpRequest;
  var url = "https://pitpanda.rocks/api/players/"   username;
  request.open("GET", url);
  request.send();
  request.onload = (e) => {
    return request.response;
  }
}

My code is running on CodePen right now https://codepen.io/casperqf/pen/NWXGeqa

CodePudding user response：

async function postData(url = '', data = {}) {
  // Default options are marked with *
  const response = await fetch(url, {
    method: 'POST', // *GET, POST, PUT, DELETE, etc.
    mode: 'cors', // no-cors, *cors, same-origin
    cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
    credentials: 'same-origin', // include, *same-origin, omit
    headers: {
      'Content-Type': 'application/json'
      // 'Content-Type': 'application/x-www-form-urlencoded',
    },
    redirect: 'follow', // manual, *follow, error
    referrerPolicy: 'no-referrer', // no-referrer, *no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url
    body: JSON.stringify(data) // body data type must match "Content-Type" header
  });
  return response.json(); // parses JSON response into native JavaScript objects
}

function updateStats(username, stats){
  postData('https://pitpanda.rocks/api/players/'   username, { stats: stats })
  .then(data => {
    console.log(data); // JSON data parsed by `data.json()` call
  });
}

updateStats('otik', 123);
