.NET Core Web APi FormData多文件上传，IFormFile强类型文件灵活绑定

前端使用FormData进行实现批量上传

<!doctype html>

<html>
<head>
    <meta charset="utf-8">

    <title>上传</title>

</head>
<form method="post" id="uploadForm" enctype="multipart/form-data">
    <input type="file" name="file" multiple />
    <input type="button" value="上传" onclick="doUpload()" />
</form>
<body>
    <script src="https://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
    <script>
        $(function () {
        });
        function doUpload() {
            var formData = new FormData($("#uploadForm")[0]);
            $.ajax({
                url: 'http://localhost:5000/api/Path/Upload',
                type: 'post',
                data: formData,
                async: false,
                cache: false,
                contentType: false,
                processData: false,
                success: function (returndata) {
                    console.dir(returndata);
                },
                error: function (returndata) {
                    console.dir(returndata);
                }
            })
        }
    </script>

批量上传选择多个文件:

 

 

 

后端.Net Core 使用 IFormFile 强类型灵活绑定获取文件信息

/// <summary>
        /// 文件上传
        /// </summary>
        /// <returns></returns>
        [HttpPost]
        public MethodResult Upload([FromForm(Name = "file")] List<IFormFile> files)
        {
            files.ForEach(file =>
            {
                var fileName = file.FileName;
                string fileExtension = file.FileName.Substring(file.FileName.LastIndexOf(".") + 1);//获取文件名称后缀 
                //保存文件
                var stream = file.OpenReadStream();
                // 把 Stream 转换成 byte[] 
                byte[] bytes = new byte[stream.Length];
                stream.Read(bytes, 0, bytes.Length);
                // 设置当前流的位置为流的开始 
                stream.Seek(0, SeekOrigin.Begin);
                // 把 byte[] 写入文件 
                FileStream fs = new FileStream("D:\\" + file.FileName, FileMode.Create);
                BinaryWriter bw = new BinaryWriter(fs);
                bw.Write(bytes);
                bw.Close();
                fs.Close();
            });
            return new MethodResult("success", 1);
        }
