无法在PHP中打印使用cURL发送的多维数组

我有一个这样的数组:

Array ( [10209064245580796] => Array ( [0] => Array ( [hashed_token] => ) [1] => Array ( [password] => ) [2] => Array ( [email] => klemen.pevc@gmail.com ) ) [10207252567926988] => Array ( [0] => Array ( [hashed_token] => ) [1] => Array ( [password] => 716b64c0f6bad9ac405aab3f00958dd1 ) [2] => Array ( [email] => milvuk@gmail.com ) ) ) 

我这样做了: $users看起来像这样:

Array ( [0] => 10209064245580796 [1] => 10207252567926988)

$arrayOfFields看起来像这样:

Array ( [0] => hashed_token [1] => password [2] => email )

所以:

$array=array();
foreach($users as $user){
   $array[$user]=array();
   foreach($arrayOfFields as $getFieldValue) {
      $user = '' . $user . '';
      $query = "SELECT `$getFieldValue` FROM $table WHERE `$column`= $user";
      $result = $mysqli->query($query);
      $fetchResult = $result->fetch_assoc();
      $getFieldValue = '' . $getFieldValue . '';
      $finalValue = $fetchResult[$getFieldValue];
      array_push($array[$user] ,array($getFieldValue=>$finalValue));
   }
} 

在这两个foreachs之后,我得到了一个数组$array,如上面第一个示例所示,我通过cURL发送此代码:

$data = array('facebook_app_id' => $facebook_app_id, 'facebook_ids' => $facebook_ids,'values_for_custom_fields' => $array);

   $endpoint_url = 'https://servis-racunara.net/api/index.php';
   $curl = curl_init($endpoint_url);
   curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
   curl_setopt($curl, CURLOPT_HTTPHEADER, Array("Authorization: Token ".$token));
   curl_setopt($curl, CURLOPT_POST, 1);
   curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
   curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
   curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
   $curl_response = curl_exec($curl);
   curl_close($curl);

   //you do not need to print results, this is just for debugging purposes
   $result = $curl_response;
   print_r($result);

因此当我执行$array时,我会在这个端点https://servis-racunara.net/api/index.php(我正在发送一些数据,包括print_r($_POST))的内部脚本中得到一个这样的数组:

Array ( [facebook_app_id] => 1512823699024883 [facebook_ids] => 10209064245580796,10207252567926988[values_for_custom_fields] => Array )

因此,在密钥values_for_custom_fields下存储了我需要处理的$array数组。当我做print_r($_POST['values_for_custom_fields']);它只是说'数组',当我尝试这个时:

foreach($_POST['values_for_custom_fields'] as $anything) {
       echo($anything);//same with print_r
}

服务器说:

  

警告:为foreach()提供的参数无效

有什么想法吗?

答案 0 :(得分:2)

问题在于您选择了错误的格式来发送数据。在您的代码中,您使用 表单提交格式 ,即application/x-www-form-urlencoded(因为它在CURL中默认使用)。 form submission formats都不支持嵌套数据(数组)。换句话说,不能在POST请求中将嵌套数组作为表单编码数据发送。

因此您必须使用其他格式发送数据。我建议使用JSON - 流行格式,允许任何级别的嵌套。在这种情况下,您必须在发送和解码之前对数据进行JSON编码 - 在端点脚本中接收它们时。您还必须为请求设置适当的Content-type标头:application/json

...
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    "Authorization: Token ".$token,
    "Content-type: application/json"
));
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
...
