Taxee API（http://www.taxee.io/）-JavaScript-如何：POST请求和传递参数

Question

Thanks for helping out with my question. I've been trying to get the federal, state, and FICA tax from a POST Request on this Taxee API ( https://market.mashape.com/stylinandy/taxee ), but haven't been able to get it working. I was able to access certain data (simply to figure out how this API works) using one of the two GET requests available for this API:

    var state = 'CA';
    var year = 2014;
    var url = ' https://taxee.io/api/v1/state/'+year+'/'+state;
    var xmlhttp = new XMLHttpRequest();
    xmlhttp.open("GET", url, true);

    xmlhttp.onload = function() {
            var result = JSON.parse(this.responseText);

            console.log(result.single.income_tax_brackets);

            xmlhttp.abort();
    }
    xmlhttp.send();

But the data I really need is in the POST request. I would like to know how to access a POST request for this, and more specifically, pass the parameters as noted on the link above. Thanks for any help you can provide, it's always greatly appreciated.

Answer 1

Figured out how to do it actually. The problem was the way that parameters are passed differently in POST requests. Hopefully this helps someone else out there:

  var url = 'https://taxee.io/api/v1/calculate/2014';
  var params = "filing_status=married&pay_rate=100000&state=CA";
  var http = new XMLHttpRequest();


  http.open("POST", url, true);

  //Send the proper header information along with the request
  http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  http.setRequestHeader("Content-length", params.length);
  http.setRequestHeader("Connection", "close");

http.onreadystatechange = function() {//Call a function when the state changes.
  if(http.readyState == 4 && http.status == 200) {
    alert(http.responseText);
  }
}
http.send(params);
