androip 앱에서 로그인이 작동하지 않습니다

Question

안녕하세요, 저는 등록 및 로그인이 필요한 Android 스튜디오에서 앱을 만들고 있습니다. 로그인 정보에 문제가있는 동안 내 등록이 정상적으로 작동하며 사실이 아닌 부울 값이 표시됩니다.

`$con = mysqli_connect("localhost", "id1013905_trhtkv", "my password",` "id1013905_user"); 


    $username = $_POST["username"]; 
    $password = $_POST["password"]; 

    $statement = mysqli_prepare($con, "SELECT * FROM user WHERE username = ?"); 
    mysqli_stmt_bind_param($statement, "s", $username); 
    mysqli_stmt_execute($statement); 
    mysqli_stmt_store_result($statement); 
    mysqli_stmt_bind_result($statement, $colUserID, $colName, $colUsername, $colAge, $colPassword); 

    $response = array(); 
    $response["success"] = false; 

    while(mysqli_stmt_fetch($statement)){ 
     if (password_verify($password, $colPassword)) { 
      $response["success"] = true; 
      $response["name"] = $colName; 
      $response["age"] = $colAge; 
     } 
    } 
    echo json_encode($response); 
    ?>

버그를 찾으려면 응답의 서버 값을 검색하는 것이 좋습니다.

나는

대신

$response = array(); 
$response["success"] = false; 

while(mysqli_stmt_fetch($statement)){ 
    if (password_verify($password, $colPassword)) { 
     $response["success"] = true; 
     $response["name"] = $colName; 
     $response["age"] = $colAge; 
    } 
} 
echo json_encode($response); 

사용

$response = array(); 
    $response["success"] = false; 
echo $statement;//or something like 
    while(mysqli_stmt_fetch($statement)){ 

     if (password_verify($password, $colPassword)) { 

echo $password; 
echo $colPassword; 
      $response["success"] = true; 
      $response["name"] = $colName; 
      $response["age"] = $colAge; 
     } 
    } 
    echo json_encode($response); 

또는 디버그 서버 측

을 의미한다. 서버 코드가 잘못되었다는 것 같습니다.
