Fine Uploader拒绝发送到api控制器

Question

我对精细上传器的端点有疑问，它拒绝点击api控制器。拖放后，它将直接进入onSubmitted，但不使用端点。请协助我所缺少的。

  var galleryUploader = new qq.FineUploader({
        element: document.getElementById("fine-uploader-gallery"),
        template: 'qq-template-gallery',
        autoUpload: false,
        request: {
            endpoint: '/api/student/uploads/',
            params: {
                StudentNumber: StudentNumber
            }
        },
        thumbnails: {
            placeholders: {
                waitingPath: '/node_modules/fine-uploader/fine-uploader/placeholders/waiting-generic.png',
                notAvailablePath: '/node_modules/fine-uploader/fine-uploader/placeholders/not_available-generic.png'
            }
        },
        validation: {
            itemLimit: 2,
            allowedExtensions: ['jpeg', 'jpg', 'gif', 'png','pdf']
        },
        uploadSuccess: {



        },
        callbacks: {
            onSubmitted: function (id, name) {
                debugger;

            },
            onError: function (id, name, errorReason, xhrOrXdr) {
                debugger;

            },
            onUpload: function (id, name, isError, responseJSON) {
                debugger;

            },
            onComplete: function (id, fileId, responseJSON) {
                debugger;

            }
        },
        retry: { enableAuto: false }
    });

//下面是我的api控制器

[HttpPost]
        [Route("api/student/uploads")]
        public async Task<object> UploadDoc(int StudentNumber)
        { 
        // needs to come here
        }
