java.net.SocketException：发送失败：ECONNRESET（连接重置对等）

Question

我尝试使用此代码连接到服务器上传图像。

try { 
     url = new URL(requestURL); 

     HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
     conn.setRequestProperty("connection", "close"); 
     System.setProperty("http.keepAlive", "false"); 
     conn.setReadTimeout(15000); 
     conn.setConnectTimeout(15000); 
     conn.setRequestMethod("POST"); 
     conn.setDoInput(true); 
     conn.setDoOutput(true); 

     OutputStream os = conn.getOutputStream(); 
     BufferedWriter writer = new BufferedWriter(
       new OutputStreamWriter(os, "UTF-8")); 
     writer.write(getPostDataString(postDataParams)); 

     writer.flush(); 
     writer.close(); 
     os.close(); 
     int responseCode = conn.getResponseCode(); 

     if (responseCode == HttpsURLConnection.HTTP_OK) { 
      BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream())); 
      sb = new StringBuilder(); 
      String response; 
      while ((response = br.readLine()) != null){ 
       sb.append(response); 
      } 
     } 
    } catch (IOException e){ 
     if (e.getMessage().indexOf("Connection reset by peer") > 0); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

我总是得到SocketException，就像上面一样。

UploadUI包含线108此代码段：

String result = rh.sendPostRequest(UPLOAD_URL,data); 

其中rh是代表RequestHandler。它应该在SQL数据库中发布图片的详细信息，但服务器端代码似乎正在工作。

你好我也面临着使用以下code.I相同problme.Now解决希望它也将帮助你..试试吧....

将这个下面的代码中的onCreate（）

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_upload_documents); 




    if (android.os.Build.VERSION.SDK_INT > 9) { 
     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() 
       .permitAll().build(); 
     StrictMode.setThreadPolicy(policy); 
    } 

    //Statement or Controls Declaration or your code 

}
