Question

这可能对某些人来说很简单，但对我来说是一个挑战。从文档中，我在POST请求的主体中获取JSON对象。格式如下所示。

当我们没有给出json对象的变量名时，如何解码json对象。我以为我会得到一个变量名，这样我就可以这样解码$data = json_decode($jsonFromSource);

我想不出办法做同样的事，有人吗？感谢。

文档说明：POST请求将发送到企业提供的URL。将传递的以下POST参数如下上面传递的参数将包含在POST请求正文中的JSON对象中。链接到简要文档https://app.kopokopo.com/push_api

{
   "service_name" : "MPESA",
   "business_number" : "888555",
   "transaction_reference" : "DE45GK45"
   "internal_transaction_id" : 3222
   "transaction_timestamp" : "2013-03-18T13:57:00Z"
   "transaction_type" : "Paybill"
   "account_number" : "445534"
   "sender_phone" : "+254903119111"
   "first_name" : "John"
   "middle_name" : "K"
   "last_name" : "Doe"
   "amount" : 4000
   "currency" : "KES"
   "signature" : "dfafwerewKkladaHOKJdafdf"
}

Answer 1

我不确定你最初是如何检索数据的 - 也许这会有所帮助吗？

$url='http://www.example.com/api/feed.json';
$data=file_get_contents( $url );
$json=json_decode( $data,true );
foreach( $json as $param => $value ) echo $param, $value, '<br />';

KOPOKOPO会将低于JSON的有效负载推送给您

"service_name=M-PESA&business_number=888555&transaction_reference=DE45GK45&internal_transaction_id=3222&transaction_timestamp=2013-03-18T13%3A57%3A00Z&transaction_type=Paybill&account_number=445=K.&last_name=Doe&amount=4000&currency=KES"

然后您可以像这样编码：

$callbackJSONData = json_encode($_POST);

结果将是...

{"service_name":"M-PESA","business_number":"888555","transaction_reference":"DE45GK45","internal_transaction_id":"3222","transaction_timestamp":"2013-03-18T13:57:00Z","transaction_type":"Paybill","account_number":"445=K.","last_name":"Doe","amount":"4000","currency":"KES"}

$jdata = json_decode($post,true);

   /*
   * We get details from $_POST only
   */
   $first_name = $jdata["first_name"];
   $middle_name = $jdata["middle_name"];
   $last_name = $jdata["last_name"];
   $paid_amount       = $jdata["amount"];
   $paying_phone_number = str_replace('+254', '0', preg_replace('/[^0-9+]/', '', $jdata["sender_phone"]));
   $transactionID       = $jdata["internal_transaction_id"];
   $transactionrefID        = str_replace('-','',$jdata["service_name"]);
   $MpesaCode = $jdata["transaction_reference"];
   $providerCurrency = $jdata["currency"];
   $providerSignature = $jdata["signature"];
   $payment_date = date("Y-m-d H:i:s",strtotime($jdata["transaction_timestamp"])); 
   $payment_time_at = date("Y-M-d",strtotime(NOW)) .' at '.date("H:i A",strtotime(NOW));
   $payment_type = $jdata['transaction_type'];
   $payment_destination = $jdata['business_number'];
