javascript - dropzone.js 文件上传超出最大请求长度

Question

我正在使用 dropzone 并在上传大于 18MB 的文档时遇到问题。我一直收到超出最大请求长度的错误，但不明白为什么。我已经研究了几天了，但无法弄清楚。我的配置示例如下。拉我遗漏的头发。

dropzone js代码:

$("#dz-documents").dropzone({
            url: "/upload/UploadDocument",
            maxFiles: 1,
            maxFilesize: 500.0,
            addRemoveLinks: true,  //*** 2/19/15 RKH *** changed
            uploadMultiple: false,
            autoProcessQueue: true,
            paramName: links,
            height: '150px',
            dictResponseError: 'Error uploading file!',
            init: function () {
                this.on("complete", function (file) {
                    if (this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0) {
                        this.removeFile(file);

                        // reload documents
                        Documents.loadDocuments($('#hdfObjectId').val(), $('#hdfRecordId').val())

                        Activity[0].refreshActivity($('#hdfObjectId').val(), $('#hdfRecordId').val())
                    }
                });
            }
        });

C#:

[HttpPost]
    public async Task<ActionResult> UploadDocument()
    {
        try
        {
            // The Name of the Upload component is "files"
            if (Request.Files != null)
            {
                OrganizationUser user = await ApplicationUserManager.GetOrganizationUser(User.Identity.GetUserId()); 

                // snipped validation code
                CloudStorageAccount storageAccount = CloudStorageAccount.Parse(Microsoft.Azure.CloudConfigurationManager.GetSetting("avnCloudStorage"));

                foreach (string name in Request.Files)
                {
                    HttpPostedFileBase file = Request.Files[name];

                    if (await docRepository.Save(file, Request.Files.AllKeys, user.OrganizationID, user.ID, user.UserID.Value.ToString()))
                    {
                        return Content("Upload was successful");
                    }
                    else
                    {
                        return Content("Error occurred on upload");
                    }
                }
            }

            return Content("Error occurred on upload");
        }
        catch (Exception ex)
        {
            logger.Error(ex);
            throw ex;
        }
    }
