Jquery 无效的内容类型：application/x-www-form-urlencoded；字符集=UTF-8

我在将请求从jQuery发送到CFC时遇到此错误

我从jquery获取文件路径，并使用该路径加载文件并将其发送到数据库

jQuery：

$("#submitbtn").click(function() {
  var fileInput = document.getElementById("fileupload");
  var filename = fileInput.files[0].name;
  var filepath = $("#fileupload").val();
  var filetype = fileInput.files[0].type;
  $.ajax({
    url: "_cfc/recommendation.cfc?method=evaluationattachment",
    type: "POST",
    data: {
      filepath: filepath,
      filename: filename,
      filetype: filetype
    },
  }).done(function(response) {
    console.log(response);

  }).fail(function(jqXHR, textStatus, errorMessage) {
    //window.location.href = "error.cfm";
  });

氟氯化碳：

尝试将AJAX调用的

contentType

更改为

multipart/form data

。如果我更改了此选项，现在我得到了“文件上载操作要求表单使用enctype=“multipart/form data”“.错误..正确，这是我让你改的。我假设您在代码的其他部分遇到了这个新错误。对的如果是的话，这是一个不同于这个问题的问题。试试这个。
