C#에서 파일을 업로드하는 REST 서비스 작성

Question

파일을 업로드하기 위해 REST 서비스를 작성했습니다. 문제가있는 것처럼 보입니다. 내가 사용하여 파일을 업로드하려고 할 때마다 그것이 나에게 오류를 제공하는 테스트 콘솔 응용 프로그램은 아래에 언급 :

An unhandled exception of type 'System.Net.WebException' occurred in System.dll

Additional information: The remote server returned an error: (400) Bad Request.

코드 - IFileUploaderService

[OperationContract] 
    [WebInvoke(Method = "POST", 
     UriTemplate = "/UploadImage", 
    RequestFormat = WebMessageFormat.Json, 
    ResponseFormat = WebMessageFormat.Json)] 
    void FileUpload(Stream stream); 

코드 - FileUploaderService.svc.cs을

public void FileUpload(Stream stream) 
    { 
     string FilePath = Path.Combine(HostingEnvironment.MapPath("~/FileServer/Uploads"), "1.txt"); 

     int length = 0; 
     using (FileStream writer = new FileStream(FilePath, FileMode.Create)) 
     { 
      int readCount; 
      var buffer = new byte[8192]; 
      while ((readCount = stream.Read(buffer, 0, buffer.Length)) != 0) 
      { 
       writer.Write(buffer, 0, readCount); 
       length += readCount; 
      } 
     } 
    }

콘솔 응용 프로그램은 파일 업로드 : 나는 다른 곳에서 언급 한 솔루션을 본

static void Main(string[] args) 
    { 

     System.Uri url = new System.Uri("http://localhost:8082/FileUploaderService.svc/uploadimage"); 
     string filePath = @"C:\test.jpg"; 



     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
     request.Accept = "application/octet-stream"; 
     request.Method = "POST"; 
     request.ContentType = "image/jpeg"; 
     using (Stream fileStream = File.OpenRead(filePath)) 
     using (Stream requestStream = request.GetRequestStream()) 
     { 
      int bufferSize = 1024; 
      byte[] buffer = new byte[bufferSize]; 
      int byteCount = 0; 
      while ((byteCount = fileStream.Read(buffer, 0, bufferSize)) > 0) 
      { 
       requestStream.Write(buffer, 0, byteCount); 
      } 
     } 
     string result; 
     using (WebResponse response = request.GetResponse()) 
     using (StreamReader reader = new StreamReader(response.GetResponseStream())) 
     { 
      result = reader.ReadToEnd(); 
     } 
     Console.WriteLine(result); 
    } 

을했으나 제대로 동작하지 않습니다. 내가 뭘 잘못하고 있는지 궁금해서 누군가가 나를 도울 수 있습니까?

Answer 1

추가 :

requestStream.Close(); 

이 줄 앞에 :

string result; 

이 스트림이 플러시하게됩니다.
