如何從帖子中提取表單數據
[英]How to extract form data from post
問題描述
我的支付網關已向我的網站發送了一個 POST，其中包含此表單數據的信息。
我嘗試將數據檢索為：
this.http
.post<any>('https://xyz.app/test', {
title: 'Testing...',
})
.subscribe((data) => {
console.log(data);
});
但沒有成功。 當我收到以下亂碼內容和錯誤時：
Unexpected error occurred

我想檢索支付交易數據，然后再顯示它。
支付網關在 PHP 中向我發送代碼：<?php
function verifychecksum_eFromStr($str, $key, $checksumvalue) {
$sadad_hash = decrypt_e($checksumvalue, $key);
$salt = substr($sadad_hash, -4);
$finalString = $str . "|" . $salt;
$website_hash = hash("sha256", $finalString);
$website_hash .= $salt;
$validFlag = "FALSE";
if ($website_hash == $sadad_hash) {
$validFlag = "TRUE";
} else {
$validFlag = "FALSE";
}
return $validFlag;
}
function decrypt_e($crypt, $ky) {
$ky = html_entity_decode($ky);
$iv = "@@@@&&&&####$$$$";
$data = openssl_decrypt($crypt, "AES-128-CBC", $ky, 0, $iv); return $data;
}
$merchantId = '1234657'; //Replace with your merchant ID
$secretKey = 'XXXXXXXXXXXXXXX'; //Replace with your secret Key
//Save incoming checksumhash into a variable and then unset it because we don't use it while verifying the checksum
$checksum_response = $_POST['checksumhash'];
unset($_POST['checksumhash']);
$data_repsonse = array();
$data_repsonse['postData'] = $_POST; //Incoming POST without checksumhash in it.
$data_repsonse['secretKey'] = $secretKey;
$key = $secretKey . $merchantId;
if (verifychecksum_eFromStr(json_encode($data_repsonse), $key, $checksum_response) === "TRUE") {
//You can further check response code and transaction status variables in $_POST to verify transaction is success or failed.
echo 'Checksum TRUE';
}else{
//The POST response has not come from Sadad. If you're sure it has come from Sadad, check you've passed correct secret key and merchant ID above.
echo 'Checksum False';
}

它可能是從服務器端發出的，因為它以 html 格式給出響應，服務器無法處理 json 解析方法。
