獲取空的JSON響應

我從數據庫中獲取數據並在json中輸出數據，但獲得空的JSON。不知道爲什麼？我得到一個空的數組職位。你可以檢查我的代碼，你能幫我一下嗎？獲取空的JSON響應

這裏是我的代碼

<?php 
//Turn off all error reporting 
//error_reporting(0); 
ini_set ("display_errors", "1"); 

    error_reporting(E_ALL); 

    define("ENCRYPTION_KEY", "[email protected]#$%^&*"); 



    /** 
    * Returns an encrypted & utf8-encoded 
    */ 
    function encrypt($pure_string, $encryption_key) { 
    $iv_size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_ECB); 
    $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); 
    $encrypted_string = mcrypt_encrypt(MCRYPT_BLOWFISH, $encryption_key, utf8_encode($pure_string), MCRYPT_MODE_ECB, $iv); 
    return $encrypted_string; 
    } 

    /** 
    * Returns decrypted original string 
    */ 
    function decrypt($encrypted_string, $encryption_key) { 
    $iv_size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_ECB); 
    $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); 
    $decrypted_string = mcrypt_decrypt(MCRYPT_BLOWFISH, $encryption_key, $encrypted_string, MCRYPT_MODE_ECB, $iv); 
    return $decrypted_string; 
    } 


    if(($_GET['action'])&&($_GET['username'])&&($_GET['key'])) { 

    $select = $_GET['action']; 
    $username =$_GET['username']; //no default 
     $key= $_GET['key']; 
     if($key=='India'){ 
     if($select=='select'){ 
     /* connect to the db */ 
    $connect = mysqli_connect('localhost','root','')or die("Couldn't connect to database!"); 
    mysqli_select_db($connect,'easy_sign') or die ("Couldn't find database"); 



$query ="SELECT * FROM origin WHERE username ='$username' "; 
$result = mysqli_query($connect,$query); 
$numrows=mysqli_num_rows($result); 
if($numrows!==0) 
{ 

while($row = mysqli_fetch_array($result)) 
{ 

    $username = $row['username']; 
    $path =  $row['path']; 
    $decrypted_path = decrypt($path, ENCRYPTION_KEY); 
    $filename = $row['filename']; 
    $decrypted_name = decrypt($filename, ENCRYPTION_KEY); 
    $date = $row['date']; 

    } 




    /* create one master array of the records */ 

    $posts = array(); 
    if(mysqli_num_rows($result)) { 
    while($post = mysqli_fetch_assoc($result)) { 
     $posts[] = array('post'=>$post); 
    } 
    } 

    /* output in necessary format */ 

    header('Content-type: application/json'); 
    echo json_encode(array('posts'=>$posts)); 




    /* disconnect from the db */ 
    @mysqli_close($link); 
     } 
    } 
    } 

    } 
    ?>

嘗試移除'header（'Content-type：application/json'）;' –

沒有影響好友.. –

你是否在'while（$ post = mysqli_fetch_assoc（$ result））'中獲得任何數據。查詢在哪裏？ –

請更改if($numrows!==0)到if($numrows > 0) ，你可以準備好您的JSON和我一樣喜歡波紋管：

<?php 
$query ="SELECT * FROM origin WHERE username ='$username' "; 
$result = mysqli_query($connect,$query); 
$numrows = mysqli_num_rows($result); 

if($numrows > 0) 
{ 
    $post = array(); 
    while($row = mysqli_fetch_array($result)) 
    { 
     $path =  $row['path']; 
     $filename = $row['filename']; 

     $post['username'] = $row['username']; 
     $post['decrypted_path'] = decrypt($path, ENCRYPTION_KEY); 
     $post['decrypted_name'] = decrypt($filename, ENCRYPTION_KEY); 
     $post['date'] = $row['date']; 
    } 
    echo json_encode($post); 
} 
?>

試試這個

if($numrows!==0) 
{ 

    $posts = array(); 
    $data=array(); 
    while($row = mysqli_fetch_array($result)) 
    { 

    $posts[]=array('username'=>$row['username'],'path'=>$row['path'],'decrypted_path '=>decrypt($path, ENCRYPTION_KEY),'filename'=>$row['filename'],'decrypted_name'=>decrypt($filename, ENCRYPTION_KEY),'date'=>$row['date']); 

    } 

    $data['posts']=$posts; 

    /* output in necessary format */ 

    header('Content-type: application/json'); 
    echo json_encode($data); 


    /* disconnect from the db */ 
    @mysqli_close($link); 
}
