>我需要帮助来实现paytm支付网关。 我正在Android应用程序中实现网关，并且已正确编码，并且没有错误，沙盒键工作正常，我也收到了响应，但随后Paytm向我发送了一个名为"检查状态API.php的文件，并对我说了这句话 我引用了我的电子邮件
对于交易状态 API，请使用 MID 和 订单 ID 并在以下链接中传递 https://pguat.paytm.com/oltp/HANDLER_INTERNAL/getTxnStatus?JsonData={"MID"："MID"，"ORDERID"："ORDERID"，"CHECKSUMHASH"："CHECKSUMHASH"}
请在该传递后对 CHECKSUMHASH 进行 URL 编码 校验和哈希值到状态 API。
我有一个附件这个文件
检查状态 API.php
public function PaytmTransactionStatus($order_id){
header("Pragma: no-cache");
header("Cache-Control: no-cache");
header("Expires: 0");
require_once("lib/config_paytm.php");
require_once("lib/encdec_paytm.php");
$checkSum = "";
$data = array(
"MID"=>"DIY12386817555501617",// please use your own MID.
"ORDER_ID"=>$order_id,
);
$key = 'bKMfNxPPf_QdZppa';
$checkSum =getChecksumFromArray($data, $key);// Please use your own merchant key value.
$request=array("MID"=>'**************',
"ORDERID"=>$order_id,"CHECKSUMHASH"=>$checkSum);
$JsonData =json_encode($request);
$postData = 'JsonData='.urlencode($JsonData);
$url = "https://pguat.paytm.com/oltp/HANDLER_INTERNAL/getTxnStatus";
$HEADER[] = "Content-Type: application/json";
$HEADER[] = "Accept: application/json";
$args['HEADER'] = $HEADER;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $args['HEADER']);
$server_output = curl_exec($ch);
return json_decode($server_output,true);
我用我的修改了 MID 和商家密钥并将其上传到服务器，但 API 不起作用，它返回我在浏览器中编写的整个代码，但它应该返回 json。
暂存和生产 URL 的 URL 存在问题。

使用以下代码检查状态：

$checkSum = "";
$paramList = array();
$paramList["MID"] = 'YOUR MID'; //Provided by Paytm
$paramList["ORDER_ID"] = $order_id; //unique OrderId for every request
$checkSum = getChecksumFromArray($paramList,"YOUR KEY");
$paramList["CHECKSUMHASH"] = urlencode($checkSum);
$data_string = 'JsonData='.json_encode($paramList);
$ch = curl_init(); // initiate curl
