将PHP代码(编码WebServices API HASH)转换为COLDFUSION

Question

我正在开发一个需要通过Webservices与另一个系统通信的ColdFusion站点.对于其他系统,我在PHP中有一个关于如何生成基于SHA512的哈希的示例,我试图在ColdFusion中复制相同的函数,但它只是不起作用.

该示例包括字符串和键,以及预期的编码结果.但是我没有使用ColdFusion获得相同的编码字符串.也许我在某个地方错过了ToBase64或其他转换功能,但我没有想法,真的需要帮助来实现这个功能.

任何帮助都会非常感激.

这是PHP示例代码

//signature to acquire a session
$apiId = '1lie8ficql9h5';
$apiSecret = 'j6hriaKY2iZi+Y2uo9JJldmO1Bq79XB8d1v2uHzAK0Zvy972mIs8ThsJSQeDlZJz+HzmLD6Q1MUZb5X1Zf9MzQ==';

//build the string to sign
//note the order of the entries is important.
//The http headers must be in alphabetical order by key name
$httpMethod = 'POST';
$apiKey = 'x-csod-api-key:'.$apiId;
$httpUrl = '/services/api/sts/session';

date_default_timezone_set('UTC');
$date = 'x-csod-date:'.date('Y-m-d').'T'.date('H:i:s').'.000';
$stringToSign = $httpMethod."\n".$apiKey."\n".$date."\n".$httpUrl;

/* produces the following string:
*  POST\nx-csod-api-key:1lie8ficql9h5\nx-csod-date:2015-09-08T11:27:32.000\n/services/api/sts/session
*/

//Generate the signature
$secretKey = base64_decode($apiSecret);
$signature = base64_encode(hash_hmac('sha512', $stringToSign, $secretKey, true));

/*
* signature produced:
* 3x5ETGSoqJa4vLl8gOFzdhxReOS0k8Nk2CpKVFN2A60ItF8wfP2tr+GUY2mELXjL90B57B5imLIrzou3ZQMfqQ==
*/

这是我的ColdFusion代码,但它不会产生相同的编码字符串:

<cfoutput>

<cfset api_id=      "1lie8ficql9h5">
<cfset api_secret=  "j6hriaKY2iZi+Y2uo9JJldmO1Bq79XB8d1v2uHzAK0Zvy972mIs8ThsJSQeDlZJz+HzmLD6Q1MUZb5X1Zf9MzQ==">

<cfset api_string= "POST\nx-csod-api-key:1lie8ficql9h5\nx-csod-date:2015-09-08T11:27:32.000\n/services/api/sts/session">

<cfset temp_key= ToString(ToBinary( api_secret))>

<cfset temp_signature= HMAC( api_string, temp_key, "HMACSHA512", "UTF-8")>
<cfset temp_signature1= ToBase64( temp_signature)>


api_string:<br> #api_string#<br><br>
temp_signature:<br> #temp_signature#<br>

Answer 1

这里有两件事情出错:

1. hmac()在ColdFusion中以十六进制返回哈希.hmac(..., true)在PHP中将哈希返回为二进制.
2. \n您要哈希的邮件中有新行(换行符).ColdFusion不会自动转换它们.PHP确实(用双引号括起来").

解:

1. 用于binaryDecode(hmac, "HEX")在ColdFusion中将哈希转换为二进制.
2. 使用#chr(10)#,而不是\n在ColdFusion中.

这是两种语言的版本:

PHP:

$apiSecret = 'j6hriaKY2iZi+Y2uo9JJldmO1Bq79XB8d1v2uHzAK0Zvy972mIs8ThsJSQeDlZJz+HzmLD6Q1MUZb5X1Zf9MzQ==';
$stringToSign = "POST\nx-csod-api-key:1lie8ficql9h5\nx-csod-date:2015-09-08T11:27:32.000\n/services/api/sts/session";

$secretKey = base64_decode($apiSecret);
$signature = base64_encode(
    hash_hmac('sha512', $stringToSign, $secretKey, true)
);

echo $signature;

ColdFusion的:

<cfset apiSecret = 'j6hriaKY2iZi+Y2uo9JJldmO1Bq79XB8d1v2uHzAK0Zvy972mIs8ThsJSQeDlZJz+HzmLD6Q1MUZb5X1Zf9MzQ=='>
<cfset stringToSign = 'POST#chr(10)#x-csod-api-key:1lie8ficql9h5#chr(10)#x-csod-date:2015-09-08T11:27:32.000#chr(10)#/services/api/sts/session'>

<cfset secretKey = toBinary(apiSecret)>
<cfset signature = toBase64(
    binaryDecode(
        hmac(stringToSign, secretKey, 'HMACSHA512'),
        'HEX'
    )
)>

<cfoutput>#signature#</cfoutput>
