【问题描述】：

我有 .net core 2.2 webapi 作为后端。我的后端必须将来自移动应用程序的请求 （照片和文本） 处理为 multipart-form 请求。请提示我如何在后端提供它？

【问题讨论】：

那里有很多例子。谷歌搜索“net core 2.2 webapi multipart/form-data”得到了一堆循序渐进的教程（例如dottutorials.net/…），我将从那里开始。

    public class SwaggerFileOperationFilter : IOperationFilter

    public void Apply(Operation operation, OperationFilterContext context)
    {
        if (operation.OperationId == "MailWithPhotos")

            operation.Parameters = new List<IParameter>
            {
                new NonBodyParameter
                {
                    Name = "awr_file",
                    Required = false,
                    Type = "file",

        var file = fIleUploadAPI.awr_file;                     // OK!!!
        var message = fIleUploadAPI.awr_message;          // OK!!!
        var tokenA = Request.Headers["Authorization"];    // OK!!!

        var fileContentStream11 = new MemoryStream();

        await fIleUploadAPI.awr_file.CopyToAsync(fileContentStream11);
        await System.IO.File.WriteAllBytesAsync(Path.Combine(folderPath,

        public string Authorization { get; set; } 
        public IFormFile awr_file { get; set; }
    }
