php - 如何在 PHP 中将复杂对象数组发送到另一个页面？

Question

我有一个数组$batchRequest，如下所示:

array(5) {
  [0]=>
  array(0) {
  }
  [1]=>
  object(Facebook\FacebookRequest)#18 (9) {
    ["app":protected]=>
    object(Facebook\FacebookApp)#9 (2) {
      ["id":protected]=>
      string(16) "xxxxxxx"
      ["secret":protected]=>
      string(32) "xxxxxxxx"
    }
    ["accessToken":protected]=>
    string(49) "xxxxx|xxxxxxx"
    ["method":protected]=>
    string(3) "GET"
    ["endpoint":protected]=>
    string(75) "/10209064245580796?fields=id%2Cname%2Cpicture%2Cgender%2Cfriends%2Cbirthday"
    ["headers":protected]=>
    array(0) {
    }
    ["params":protected]=>
    array(0) {
    }
    ["files":protected]=>
    array(0) {
    }
    ["eTag":protected]=>
    NULL
    ["graphVersion":protected]=>
    string(4) "v2.5"
  }
  [2]=>
  object(Facebook\FacebookRequest)#17 (9) {
    ["app":protected]=>
    object(Facebook\FacebookApp)#9 (2) {
      ["id":protected]=>
      string(16) "xxxxx"
      ["secret":protected]=>
      string(32) "xxxxxxx"
    }
    ["accessToken":protected]=>
    string(49) "xxxx|xxxxxxxx"
    ["method":protected]=>
    string(3) "GET"
    ["endpoint":protected]=>
    string(75) "/10208823390691752?fields=id%2Cname%2Cpicture%2Cgender%2Cfriends%2Cbirthday"
    ["headers":protected]=>
    array(0) {
    }
    ["params":protected]=>
    array(0) {
    }
    ["files":protected]=>
    array(0) {
    }
    ["eTag":protected]=>
    NULL
    ["graphVersion":protected]=>
    string(4) "v2.5"
  }
  [3]=>
  object(Facebook\FacebookRequest)#19 (9) {
    ["app":protected]=>
    object(Facebook\FacebookApp)#9 (2) {
      ["id":protected]=>
      string(16) "xxxxx"
      ["secret":protected]=>
      string(32) "xxxxxxx"
    }
    ["accessToken":protected]=>
    string(49) "xxxxx|xxxxxxx"
    ["method":protected]=>
    string(3) "GET"
    ["endpoint":protected]=>
    string(74) "/1294280923934896?fields=id%2Cname%2Cpicture%2Cgender%2Cfriends%2Cbirthday"
    ["headers":protected]=>
    array(0) {
    }
    ["params":protected]=>
    array(0) {
    }
    ["files":protected]=>
    array(0) {
    }
    ["eTag":protected]=>
    NULL
    ["graphVersion":protected]=>
    string(4) "v2.5"
  }
  [4]=>
  object(Facebook\FacebookRequest)#20 (9) {
    ["app":protected]=>
    object(Facebook\FacebookApp)#9 (2) {
      ["id":protected]=>
      string(16) "xxxxx"
      ["secret":protected]=>
      string(32) "xxxxxxxx"
    }
    ["accessToken":protected]=>
    string(49) "xxxxx|xxxxxxxxxx"
    ["method":protected]=>
    string(3) "GET"
    ["endpoint":protected]=>
    string(74) "/1274474365912572?fields=id%2Cname%2Cpicture%2Cgender%2Cfriends%2Cbirthday"
    ["headers":protected]=>
    array(0) {
    }
    ["params":protected]=>
    array(0) {
    }
    ["files":protected]=>
    array(0) {
    }
    ["eTag":protected]=>
    NULL
    ["graphVersion":protected]=>
    string(4) "v2.5"
  }
}

所以它是一个数组，其元素是复杂对象。我需要将它们发送到另一个名为 parallelImport.php 的页面。这是我尝试过的:

使用 JSON

$data = array('batchArrayChild' => json_encode($batchRequest), 'app_id' => $appId, 'app_secret' => $appSecret);
$endpoint_url = 'https://some-domain.net/pages/parallelImport.php';
$curl = curl_init($endpoint_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($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);
$result = $curl_response;
print_r($result);

如您所见，我 json_encode 编辑了 $batchRequest 并通过 cURL 发送它，以下是它的输出:

string(16) "[[],{},{},{},{}]"

使用http_build_query

$data = array('batchArrayChild' => http_build_query($batchRequest), 'app_id' => $appId, 'app_secret' => $appSecret);
$endpoint_url = 'https://some-domain.net/pages/parallelImport.php';
$curl = curl_init($endpoint_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($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);
$result = $curl_response;
print_r($result);

在我对parallelImport.php执行var_dump($_POST['batchArrayChild'])之后，它说:

string(0) ""

您知道我可以将此数组发送到执行脚本并获得某种响应的任何其他方式吗？

我不喜欢在系统之间发送复杂的(内部)对象，因此我会创建一个具有公共(public)属性的 DTO(数据传输对象)，并使用该对象发送数据以避免服务之间的任何对象耦合。如果您想让它变得简单，DTO 甚至可以是 stdClass 类型。

如果您想让服务彼此高度依赖(包括共享状态)，您可以尝试对数据使用 serialize()
