用于支付网关的 PHP 交易状态 API

Question

我正在开发 PayUMoney 支付网关。我已经整合成功了。现在，在接受 PayUMoney 的审核流程之前，他们突然告诉我，我必须在我的门户上集成交易状态 API。他们为我提供了 API。我也已经整合了。以下是他们提供给我的代码。

$key = "gtKFFx";
$salt = "eCwWELxi";
$command = "verify_payment";
$var1 = "NPMM87334121";

//hash formaula
$hash_str = $key  . '|' . $command . '|' . $var1 . '|' . $salt ;
$hash = strtolower(hash('sha512', $hash_str));
$r = array('key' => $key , 'hash' =>$hash , 'var1' => $var1, 'command' => $command);
$qs= http_build_query($r);
$wsUrl = "https://test.payu.in/merchant/postservice.php?form=1";
//$wsUrl = "https://info.payu.in/merchant/postservice?form=1";

$c = curl_init();
curl_setopt($c, CURLOPT_URL, $wsUrl);
curl_setopt($c, CURLOPT_POST, 1);
curl_setopt($c, CURLOPT_POSTFIELDS, $qs);
curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 0);
$o = curl_exec($c);
if (curl_errno($c)) {
  $sad = curl_error($c);
  throw new Exception($sad);
}
curl_close($c);

$valueSerialized = @unserialize($o);
if($o === 'b:0;' || $valueSerialized !== false) {
  print_r($valueSerialized);
}
print_r($o);

上面的代码给我的回应如下：

Array

    [status] => 1
    [msg] => 1 out of 1 Transactions Fetched Successfully
    [transaction_details] => Array
        (
            [NPMM87334121] => Array

                    [transaction_amount] => 100813.00
                    [txnid] => TRANS-2011-01-05-11-05-00

                    [udf1] => 
                    [udf3] => 
                    [udf4] => 
                    [udf5] => 
                    [field2] => 
                    [field9] => FSS0001-Authentication Not Available
                    [error_code] => E500
                    [payment_source] => payu
                    [card_type] => VISA
                    [error_Message] => Bank failed to authenticate the customer
                    [net_amount_debit] => 0.00
                    [disc] => 0.00
                    [mode] => CC
                    [PG_TYPE] => HDFCPG
                    [card_no] => 411111XXXXXX1111
                    [name_on_card] => Demo
                    [udf2] => 
                    [addedon] => 2018-01-05 11:21:36
                    [status] => failure
                    [unmappedstatus] => failed
                    [Merchant_UTR] => 
                    [Settled_At] => 
                )

        )

)

在此之后，我编写了以下行来访问上述响应。

$checkout_data = $o['transaction_details'][$var1];

但是在这行之后它给了我以下错误。

Message: Illegal string offset 'transaction_details'
Message: Illegal string offset 'NPMM87334121'

我不明白我哪里做错了。 payu 给出的响应位于数组中，因此如果我将其作为数组访问，仍然会出现错误。

Answer 1

使用此 url 获取 Payu Status Api

$wsUrl = "https://test.payu.in/merchant/postservice.php?form=2";

注意变量形式=2而不是1
此 url 返回 json 输出 而形式=1 返回难以操作的数组输出

Answer 2

它返回 pre 标记内数组的 print_r 。响应不是数组而是文本 根据 manojit 我们必须使用

$wsUrl = "https://test.payu.in/merchant/postservice.php?form=2";

form=2 获取json格式

数组
（

[msg] => 1 笔交易已成功获取

Answer 3

更新代码的 Curl 部分，如下所示：

$wsUrl = "https://info.payu.in/merchant/postservice?form=2";
$c = curl_init();
curl_setopt($c, CURLOPT_URL, $wsUrl);
curl_setopt($c, CURLOPT_POST, 1);
curl_setopt($c, CURLOPT_POSTFIELDS, $qs);
curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 0);
$o = curl_exec($c);
if (curl_errno($c)) {
  $sad = curl_error($c);
  throw new Exception($sad);
}
curl_close($c);

$valueSerialized = @unserialize($o);
if($o === 'b:0;' || $valueSerialized !== false) {
  print_r($valueSerialized);
} 
//print_r($o);

$o = json_decode($o);

foreach($o->transaction_details as $key => $val){
    if(($val->status=="success")&&($val->unmappedstatus=="captured")){
        // Update
    }
}

Answer 4

$valueSerialized = @unserialize($o);
if($o === 'b:0;' || $valueSerialized !== false) {
  print_r($valueSerialized);
}
print_r($o);

$checkout_data = $o['transaction_details'][$var1];

您正在访问（序列化的）字符串

$o

而不是未序列化的对象

$valueSerialized

；

所以应该是

$checkout_data = $valueSerialized['transaction_details'][$var1];

您的脚本中存在巨大问题：

• 您关闭了安全性，您应该删除线路

  curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);

  curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 0);

• 变量名称具有误导性（例如称为序列化的变量中的未序列化值）

• 您没有对 HTTP 响应状态代码进行错误检查，并且您正在抑制

  @unserialize($o)

  中的错误。不要使用

  @

  。
