目前我正在使用php进行基于财务的应用程序。我与第三方api集成以获取用户数据。
基于集成，它们使用签名和有效负载进行身份验证。
根据文件，我为我的观点做了一切正确，但我得到了回应
SignatureDoesNotMatch我们计算的请求签名与您提供的签名不符。
根据文件：
计算签名：必要时，请求必须由发件人签名。请求的签名计算如下：
6）生成压缩有效负载的SHA1摘要。 7）Base16编码生成的SHA1摘要。 8）使用Perfios提供的RSA私钥加密编码的摘要。 9）Base16编码加密的摘要。
我的脚本在这里：
$condense_payload ='<payload><vendorId>test</vendorId><txnId>dummyApplicationId</txnId><emailId>'.$emailid.'</emailId><destination>netbankingFetch</destination><returnUrl>https://www.google.com</returnUrl></payload>';
$condense_payload_updated = trim(preg_replace('/(?<=\>)(\r?\n)|(\r?\n)(?=\<\/)/', $condense_payload));
$payload ='
<payload>
<vendorId>test</vendorId>
<txnId>dummyApplicationId</txnId>
<emailId>'.$emailid.'</emailId>
<destination>netbankingFetch</destination>
<returnUrl>https://www.google.com</returnUrl>
</payload>';
/* Convert to Sha1 */
$sha1_convert = sha1($condense_payload_updated);
/* Convert to Hex (base16) */
$first_base16_convert=bin2hex($sha1_convert);
$fp = fopen("private_key", "r");
$private_key_string = fread($fp, 8192);
fclose($fp);
/* Convert to private key */
$private_key = openssl_get_privatekey($private_key_string);
$encrypted_private="";
/* Encrypt digest using key */
openssl_private_encrypt($first_base16_convert, $encrypted_private, $private_key, OPENSSL_PKCS1_PADDING);
/* Convert to Hex (base16) */
$signature=bin2hex($encrypted_private);
所以这里生成了有效负载和签名，并使用post方法发送url：
<html>
<body onload='document.autoform.submit();'>
<form name='autoform' method='post' action='https://demo.perfios.com/KuberaVault/insights/start'>
<input type='hidden' name='payload' value='<?php echo $payload; ?>' />
<input type='hidden' name='signature' value='<?php echo $signature; ?>'/>
</body>
</html>
所以最后我得到了：
SignatureDoesNotMatch我们计算的请求签名与您提供的签名不符。

我的观点是，我生成了签名和有效负载，但我不知道我的脚本出了什么问题。任何人都可以指导我吗？
它试图解决代码中的一些可能问题。也许尝试这样的基础。
