使用 ajax（发送方法）在服务器上出现错误 500

Question

I use Javascript and AJAX to send some informations. The code below works on my local machine but not on my server.

var str = "/Nouvelle_Fiche" + "/" + id_fiche + "/" + id_process + "/" + type_process + "/" + id_impact + "/" + id_auteur + "/" + id_situation + "/" + questionnaires;

xmlhttp.open("POST", str, true);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send();

I have an error 500 "Internal Server Error" with the line "xmlhttp.send();". Can you help me please ? Thank you !

Try to send data as json if you can or send null in ajax.send functions. Try to change Content-type.

var ajax = new XMLHttpRequest();
ajax.open("GET", url, true);
ajax.setRequestHeader("Content-type", "application/json");
ajax.send( data );

ajax.onreadystatechange = function() {
  if (ajax.readyState == 4 && ajax.status == 200) {
    console.log(ajax.response);
  }
};
