Dropzone.js不上传.zip文件

Question

我必须使用dropzone上传ZIP档案，当我选择档案时，我看到进度栏从0到100，但是请求永远不会到达服务器，因此永远不会调用我在表单中指定的操作。 这是我页面上的文件上传器：

<form action="URL_ACTION" class="dropzone dropzone-file-area" id="dropzoneZip" method="post" enctype="multipart/form-data">
  <div class="fallback">
     <input name="file" type="file" />
     <input type="submit" value="Upload" name="upload" />
  </div>
</form>

这是我的JS代码：

Dropzone.options.dropzoneZip = {
        dictDefaultMessage: "Drag files here o click to upload",
        maxFiles: 1,
        acceptedFiles: ".zip",
        init: function () {
            this.on("error", function (file, errorMessage) {
                alert("error : " + errorMessage);
            });
            this.on("addedfile", function (e) {
                var n = Dropzone.createElement("<a href='javascript:;' class='btn red btn-sm btn-block'>Remove</a>"),
                    t = this;
                n.addEventListener("click", function (n) {
                    n.preventDefault(), n.stopPropagation(), t.removeFile(e)
                }), e.previewElement.appendChild(n)
            }),
            this.on("complete", function (data) {
                if (data.xhr.responseText == "success") {
                    swal({
                        title: 'Success',
                        text: 'File uploaded',
                        type: "success"
                    }).then(
                    function () {
                        $(".se-pre-con").fadeIn("slow");
                        location.reload();
                    })
                }
            }),
            this.on('error', function (file, errorMessage) {
                if (errorMessage != "success") {
                    var errorDisplay = document.querySelectorAll('[data-dz-errormessage]');
                    errorDisplay[errorDisplay.length - 1].innerHTML = errorMessage;
                }
                else if (errorMessage.indexOf('404') !== -1) {
                    var errorDisplay = document.querySelectorAll('[data-dz-errormessage]');
                    errorDisplay[errorDisplay.length - 1].innerHTML = 'Error 404: The upload page was not found on the server';
                } else if (errorMessage.indexOf('500') !== -1) {
                    var errorDisplay = document.querySelectorAll('[data-dz-errormessage]');
                    errorDisplay[errorDisplay.length - 1].innerHTML = 'Error 500: Internal server error';
                }
            });
        }
    }

这是我检查文件类型的操作代码：

  if (Request.Files != null && Request.Files.Count > 0)
  {
      if (Request["type"]=="zip" && (Request.Files[0].ContentType == "application/x-compressed" || Request.Files[0].ContentType == "application/x-zip-compressed" || Request.Files[0].ContentType == "application/zip" || Request.Files[0].ContentType == "multipart/x-zip"))
        uploadZip();
  }

但是，这一行动从未实现。 我尝试使用相同的方法上传图片，并且可以正常工作。 我无法弄清楚我在做什么

如果您有xamp / uniserver，那么它可以完全正常工作我已经测试了上面的代码创建一个uploads文件夹，以便在服务器上上传文件

好的，我发现了原因：我尝试上传的文件超过了Web.config文件上的maxRequestLength参数。 使用较小的文件，上传可以正常工作
