Question

我已阅读过每篇网络帖子，但我仍然不知道自己做错了什么。从Fiddler开始，我正在尝试发布多个项目但它无效。我无法发布.jpeg，但.txt无效。对该方法的第一次请求是成功的，但所有后续请求都不会，并且将生成“ MIME多部分流的意外结束.MIME多部分消息未完成”或“异步模块或处理程序在异步操作仍处于等待状态时完成“。如果我只是在部分/边界中发送文本条目，它将只看到第一个 - 其他被忽略

Web API

[HttpPost]
[MimeMultipart]
public async Task<IHttpActionResult> PostAsync()
     {
      var uploadPath = HttpContext.Current.Server.MapPath("~/Uploads");
      Directory.CreateDirectory(uploadPath);
      var provider = new MultipartFormDataStreamProvider(uploadPath);
      // THIS IS WHERE THE ERRORS HAPPEN
      await Request.Content.ReadAsMultipartAsync(provider);
      // NEVER HAS A NAME(S),, EVEN WHEN NO ERROR
      var localFileName = provider.FileData.Select(multiPartData => multiPartData.LocalFileName).FirstOrDefault();

        foreach (var stream in provider.Contents)
        {
            var fileBytes = stream.ReadAsByteArrayAsync();
            var response = Request.CreateResponse(HttpStatusCode.OK);
            response.Content = new StringContent("Successful upload", Encoding.UTF8, "text/plain");
            response.Content.Headers.ContentType = new MediaTypeWithQualityHeaderValue(@"text/html");
        }
      // omitted code

我应该使用其他content-type吗？我在这里死了。
