如何将参数和上传图像同时传递给 One web api？

Question

我使用这个控制器：

 public class uploadphotosController : ApiController
    {
        public Task<HttpResponseMessage> Post( )
        {

            // Check if the request contains multipart/form-data.
            if (!Request.Content.IsMimeMultipartContent())
            {
                throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
            }

            string root =HostingEnvironment.MapPath("~/photos");//Burdaki app data klasoru degisecek
            var provider = new MultipartFormDataStreamProvider(root);

            // Read the form data and return an async task.
            var task = Request.Content.ReadAsMultipartAsync(provider).
                ContinueWith<HttpResponseMessage>(t =>
                {
                    if (t.IsFaulted || t.IsCanceled)
                    {
                        return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, t.Exception);
                    }

                    // This illustrates how to get the file names.
                    foreach (MultipartFileData file in provider.FileData)
                    {

                        string fileName = file.LocalFileName;
                        string originalName = file.Headers.ContentDisposition.FileName;


                        FileInfo file2 = new FileInfo(fileName);
                        file2.CopyTo(Path.Combine(root, originalName.TrimStart('"').TrimEnd('"')), true);
                        file2.Delete();

                        //Trace.WriteLine(file.Headers.ContentDisposition.FileName);
                        // Trace.WriteLine("Server file path: " + file.LocalFileName);
                    }
                    return Request.CreateResponse(HttpStatusCode.OK);
                });


            return task;
        }

    }

我在 WebApiConfig.cs 中使用它

   config.Routes.MapHttpRoute(
             name: "DefaultApi_uploadphotos",
             routeTemplate: "api/{ext}/uploadphotos/",
             defaults: new
             {
                 controller = "uploadphotos"
             });

它工作正常，但我需要同时上传带有发送电子邮件和密码的图像。因为如果用户存在，我想上传图片。以我的方式，每个人都以用户身份上传照片。我想将图像和一些参数（如电子邮件和密码）发送到同一个 Web api。

我该怎么做？

什么对我有用：

public async Task<HttpResponseMessage> PostFile(string a, string b)
{
     var requestStream = await Request.Content.ReadAsStreamAsync();
  ...
}

路由：

config.Routes.MapHttpRoute(
    name: "ControllerApi",
    routeTemplate: "/{controller}/{a}/{b}"
);

发送文件：

var request = (HttpWebRequest) HttpWebRequest.Create("http://host/controller/hello/world");
request.Method = "POST";
var stream = request.GetRequestStream();
var docFile = File.OpenRead(sourceFile);
docFile.CopyTo(stream);
docFile.Close();
stream.Close();
var response = request.GetResponse();
