我一直遵循本教程来支持作为MVC4 WebAPI的一部分的文件上传:http://blogs.msdn.com/b/henrikn/archive/2012/03/01/file-upload-and-asp-net-web-api.aspx
当我的控制器收到请求时,它会抱怨“mime多部分消息不完整”。有人知道如何调试这个程序吗?我已经尝试将流的位置重置为0,以防在它击中处理程序之前有其他东西正在读取它。
我的HTML如下所示:

<form action="/api/giggl" method="post" enctype="multipart/form-data">
    <span>Select file(s) to upload :</span>
    <input id="file1" type="file" multiple="multiple" />
    <input id="button1" type="submit" value="Upload" />
</form>

我的控制器的post方法如下:
    public Task<IEnumerable<string>> Post()
    {
        if (Request.Content.IsMimeMultipartContent())
        {
            Stream reqStream = Request.Content.ReadAsStreamAsync().Result;
            if (reqStream.CanSeek)
            {
                reqStream.Position = 0;
            }

            string fullPath = HttpContext.Current.Server.MapPath("~/App_Data");
            var streamProvider = new MultipartFormDataStreamProvider(fullPath);

            var task = Request.Content.ReadAsMultipartAsync(streamProvider).ContinueWith(t =>
            {
                if (t.IsFaulted || t.IsCanceled)
                    Request.CreateErrorResponse(HttpStatusCode.InternalServerError, t.Exception);

                var fileInfo = streamProvider.FileData.Select(i =>
                {
                    var info = new FileInfo(i.LocalFileName);
                    return "File uploaded as " + info.FullName + " (" + info.Length + ")";
                });
                return fileInfo;

            });
            return task;
        }
        else
        {
            throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotAcceptable, "Invalid Request!"));
        }
    }

我遗漏了什么明显的东西吗?>

最佳答案

你能试着在输入文件中添加“name”属性吗?

<input name="file1" id="file1" type="file" multiple="multiple" />

关于c# - WebAPI上传错误。 MIME多部分流的预期结尾。 MIME分段消息不完整,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19619100/
