php - paytm 在核心 php 中的集成

Question

我想在我的站点中集成 paytm 钱包。可以使用什么参数以及可以使用什么参数来生成校验和？

$data=array();
    $data["MID"]=$this->merchant_id;
    $data["ORDER_ID"]=$param['transaction_id'];
    $data["CUST_ID"]=$user['id'];
    $data["INDUSTRY_TYPE_ID"]=$this->industry_type;
    if($param['paytm_type']=="WEB"){
        $data["CHANNEL_ID"]=$this->web_channel_id;
        $data["WEBSITE"]=$this->web_website;
    }
    else if($param['paytm_type']=="APP"){
        $data["CHANNEL_ID"]=$this->app_channel_id;
        $data["WEBSITE"]=$this->app_name;
    }
    $data["TXN_AMOUNT"]=$param['amount'];

还有我的postfiled数据，比如

$postfiled=array(        
        "MID"         =>$data["MID"],
        "ORDER_ID"    =>$param['transaction_id'],
        "CUST_ID"     =>$user['id'],
        "TXN_AMOUNT"  =>$param['amount'],
        "CHANNEL_ID"  =>$data["CHANNEL_ID"],
        "INDUSTRY_TYPE_ID"=>$data["INDUSTRY_TYPE_ID"],
        "WEBSITE"     =>$data["WEBSITE"],
        "CHECKSUMHASH"=>  \App\Lib\PaytmLib\encdec_paytm::getChecksumFromArray($data,$this->merchant_key),
        "END_POINT"   =>$this->end_point,
        "CALLBACK_URL"=>$returnUrl
    );

您可以使用以下函数获取 paytm 校验和。 Here是 PHP 的示例工具包。

 1. getChecksumFromString : For generating the checksum
 2. verifychecksum_eFromStr : For verifing the checksum
