IFormFile 未被 dropzone uploadMultiple 请求填充

问题描述

我遇到的问题是 IFormFile 的列表没有填充给定的文件，但是当我调用 HttpContext.Request.Form.Files 时；然后我可以访问这些文件.我更喜欢使用 IFormFile，因为它似乎是新的 Dotnet 核心 2.0 做事方式.

The problem I am having is that the List of IFormFile is not being populated with the given files but when i call HttpContext.Request.Form.Files; then I have access to the files. I would prefer to use IFormFile as it seems to be new Dotnet core 2.0 way of doing things.

我有以下请求负载:

具有以下请求标头:

和 Razor 页面处理程序:

And Razor pages handler:

public async Task<ActionResult> OnPostSend(ConditionResponse conditionResponse)
    {
        var files = HttpContext.Request.Form.Files;
    }

条件响应模型:

public class ConditionResponse
{
    public List<string> Plots { get; set; }

    public string Comments { get; set; }

    public List<IFormFile> Files { get; set; }
}

推荐答案

在查看来自 html5 多文件上传的请求后，我注意到该请求没有将索引添加到文件名 (files[n]).Dropzone.js 这样做，所以有一个变通办法.如果您将 paramName 选项添加到 Dropzone JS 配置并让它调用返回文件的方法，您将获得与 html5 多文件上传相同的行为.

After looking at the request from a html5 multiple file upload I noticed the request does not add the indexes to the filename (files[n]). Dropzone.js does this so there is a work around. If you add the paramName option to Dropzone JS config and have it call a method which returns files you will get the same behaviour as the html5 multiple file upload.

function myParamName() {
                return "files";
            }

 Dropzone.options.myDropzone = {
                uploadMultiple: true,
                paramName: myParamName,
}
