asp.net-mvc - dropzonejs 多文件上传无法按预期工作

Question

我正在尝试使用多重上传，但在我的 MVC 操作中，我没有获得上传文件的列表，而是获得每个上传项目的文件 []。

我正在上传 2 个文件，但是当我通过以下方式在我的 Controller 中访问它时:

        foreach (string filename in Request.Files)
        {
            var file = Request.Files[filename];
            //file.name always reads from file[] and picks the first file in all requests


        }

我的完整请求是:

Dropzone 配置是:

<script type="text/javascript">
        Dropzone.autoDiscover = false;

        var myDropzone = new Dropzone("form#my-awesome-dropzone", {
            paramName: "files", // The name that will be used to transfer the file
            autoProcessQueue: false,
            forceFallback: false,
            uploadMultiple: true,
            maxFilesize: 10,
            previewsContainer: ".dropzone-previews",
            clickable: ".dropzone" //make only this region clickable
        });

        myDropzone.on("addedfile", function (file) {
            /* Maybe display some more file information on your page */
            console.debug("added a file: " + file.name);
        });

        myDropzone.on("success", function (file) {
            $("#drop-success").show();
        });

        $("#btnDropzone").click(function () {
            myDropzone.processQueue();
        });
    });
</script>

如何在我的 Controller 中获取每个上传的文件以便我可以处理它？<​​/h3>

Answer 1

如果输入名称 file[] 确实是问题所在，那么您可以将 Dropzone 选项 uploadMultiple 设置为 false。这将创建多个请求并单独发送每个文件，而不是在一个请求中发送所有并行上传的文件。
