在java中的登錄系統HttpURLConnection和php服務器

我在JAVA中有一個小程序，我想創建一個登錄系統，但不直接連接到數據庫。我想，首先經過在PHP然後用一個程序PHP在我的PHP服務器和MySQL 連接我有：？在java中的登錄系統HttpURLConnection和php服務器

<?php 
$username = $_POST['username']; 
$password = $_POST['password']; 

$mysqli = new mysqli('localhost', 'root', '', 'persec'); 
if (isset($_POST['username']) and isset($_POST['password'])){ 
    $username = $mysqli->real_escape_string($_POST['username']); 
    $password = trim($_POST['password']); 
    $pass = $mysqli->real_escape_string($_POST['password']); 

    $sql = "SELECT * FROM acesso WHERE username='$username'"; 

    $result = $mysqli->query($sql); 

    header("Content-Type:text/plain"); 
    http_response_code(200) 

    if($result->num_rows === 1){ 
     $row = $result->fetch_array(MYSQLI_ASSOC); 
     if (password_verify($password, $row['password'])){ 
      $_SESSION['username'] = $username; 

     echo "true"; 
     }else{ 
      echo "false"; 
     }

，現在，我有這個在Java中

String username = txtUser.getText(); 
      String password = new String(txtpass.getPassword());  
      try { 
       String urlParam = "u="+username+"&p="+password; 
       byte[] postData = urlParam.getBytes(StandardCharsets.UTF_8); 
       int postDataLength = postData.length; 
       URL url = new URL("http://localhost/dashboard3/loginServer.php"); 
       HttpURLConnection conn = (HttpURLConnection)url.openConnection(); 

       conn.setDoOutput(true); 
       conn.setInstanceFollowRedirects(false); 
       conn.setRequestMethod("POST"); 
       conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
       conn.setRequestProperty("charset", "utf-8"); 
       conn.setRequestProperty("Content-Length", Integer.toString(postDataLength)); 
       conn.setUseCaches(false); 
       try(DataOutputStream wr = new DataOutputStream(conn.getOutputStream())) { 
         wr.write(postData); 
         System.out.println(postData); 
        } 

      } catch (MalformedURLException e1) { 
       // TODO Auto-generated catch block 
       e1.printStackTrace(); 
      }catch (IOException e1){ 
       e1.printStackTrace(); 
      }

我認爲一切都很好，知道..問題是：如何我可以從Java獲得在PHP確認，如果我可以登錄或不？

提示：您可以嘗試使用「HttpUrlConnection」中的[InputStream]（https://docs.oracle.com/javase/7/docs/api/java/net/URLConnection.html#getInputStream（）） '讀取php服務器返回的內容。 –

如果您在http響應的主體中返回「true」或「false」，則可以將此代碼添加到您已有的代碼中，並且它將從輸入流中讀取一行。

try(DataOutputStream wr = new DataOutputStream(conn.getOutputStream())) { 
    wr.write(postData); 
    System.out.println(postData); 
} catch (Exception e) { ... } 

... 

BufferedReader in = new BufferedReader(new 
InputStreamReader(conn.getInputStream())); 
String responseMsg = in.readLine(); 

if(responseMsg != null){ 
    System.out.println(responseMsg); 
} 
in.close(); 
...
