Question

我在将请求从jQuery发送到CFC时收到此错误。

我从jquery获取文件路径并使用该路径我正在加载文件并将其发送到数据库。

jQuery的：

$("#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";
  });

CFC：
