         * [upfile 文件上传]
         * @return {[Object]} [成功回调]
         */
        function upfile() {
            
            var formData = new FormData();

            formData.append("接收字段1", document.getElementById(&#39;file1&#39;).files[0]);
            // console.log(document.getElementById(&#39;file1&#39;).files[0]);

                contentType: false, // jQuery不要去设置Content-Type请求头

                success: function(data) { // 成功回调
