從Android設備發送哈希的字節數組到服務器套接字並存儲它

Question

我在接收端即服務器有問題。它正在接收數據，我試圖將這些數據存儲在一個字節數組中。我正在做一個while循環，但它永遠不會終止，我不知道爲什麼。

Android的代碼片段：

try { 
     ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); 
     MessageDigest digest = MessageDigest.getInstance("SHA-256"); 

     byte[] keyBytes = keystore.get("secretkey"); 
     byte[] nonceBytes = nonce.getBytes("UTF-8"); 

     outputStream.write(nonceBytes); 
     outputStream.write(keyBytes); 

     byte[] bytesToEncrypt = outputStream.toByteArray(); 

     byte[] hashedBytes = digest.digest(bytesToEncrypt); 

     Socket clientSocket = new Socket(myserver, myport); 
     OutputStream outToServer = clientSocket.getOutputStream(); 
     outToServer.write(hashedBytes); 
    } 

服務器片斷：

try { 
    ServerSocket serverSocket = new ServerSocket(8311); 

    while(true) { 
     Socket connectionSocket = serverSocket.accept(); 
     System.out.println("Receivied something.."); 

     InputStream inFromClient = connectionSocket.getInputStream(); 

     byte[] buffer = new byte[connectionSocket.getReceiveBufferSize()]; 

     try { 
      System.out.println("Trying to store data in byte array"); 
     int bytesRead = -1; 

     while((bytesRead = inFromClient.read(buffer)) != -1) { 
      baos.write(buffer, 0, bytesRead); 
     } 

     // This never prints 
     System.out.println("Done"); 


     challengeReceived = baos.toByteArray(); 
     } 
     catch(Exception e) { 
      e.printStackTrace(); 
     } 
} 

它永遠不會打印 「完成」 這個實現。任何意見讚賞。當客戶機關閉連接

服務器從

while((bytesRead = inFromClient.read(buffer)) != -1) { 
     baos.write(buffer, 0, bytesRead); 
    } 

循環退出。

嘗試使用close()調用來關閉客戶端的連接。通過這種方式：

outToServer.write(hashedBytes); 
clientSocket.close();
