This is driving me crazy.
I am trying to generate a signature as suggested here: https://www.reed.co.uk/developers/SignatureTest
This way:
function createSignature($queryUrl, $timestamp, $apiKey, $http = "GET", $agent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"){
$signature = $http . $agent . $queryUrl . "www.reed.co.uk" . $timestamp;
$signature = base64_encode(hash_hmac("sha1", $signature, $apiKey, true));
return $signature;
}
$clientId = 1;
$timestamp = "2016-05-13T09:22:50Z";
$apiKey = "bacd2d2d-8b69-43c8-94c5-4a24c0269b79";
$queryUrl = "https://www.reed.co.uk/recruiter/api/1.0/cvsearch";
$reedQuery = \Httpful\Request::get($queryUrl)
->addHeaders(array(
"X-ApiSignature" => createSignature($queryUrl, $timestamp, $apiKey),
"X-ApiClientId" => $clientId,
"X-TimeStamp" => $timestamp
))
->expectsJson()
->send();
print_r($reedQuery);
Now for some reasons it returns this on my server: WRTjqQKfyEQyLJEzWWuT3SWgGPk=
While the expected result is: JUgvCh5oeFYe1HDmfiMObOu1+nQ=
I tried everything, even swapping from little endian to big endian. Nothing.
What is wrong??? :(
I struggled with the same issue; the solution is posted here under a different question.
The issue is that the string key (GUID) needs its order of the 2-character hexadecimal numbers reversed in the first 3 segments ( http://msdn.microsoft.com/en-us/library/system.guid.tobytearray.aspx ).
Example to create the hash (using your key above):
$apiToken = 'bacd2d2d-8b69-43c8-94c5-4a24c0269b79';
$stringToSign = 'POSTReedAgenthttps://www.reed.co.uk/recruiter/api/1.0/jobswww.reed.co.uk2017-11-11T13:50:06+00:00';
$hexStr = str_replace('-','',$apiToken);
$c = explode('-',chunk_split($hexStr,2,'-'));
$hexArr = array($c[3],$c[2],$c[1],$c[0],$c[5],$c[4],$c[7],$c[6],$c[8],$c[9],$c[10],$c[11],$c[12],$c[13],$c[14],$c[15]);
$keyStr = '';
for ($i = 0; $i < 16; ++$i) {
$num = hexdec($hexArr[$i]);
$keyStr .= chr($num);
}
$apiSignature = base64_encode(hash_hmac('sha1',$stringToSign,$keyStr,true));
This produces a hash that matches that from the Signature Test .
对于sha1,只需要hash_hmac函数
hash_hmac('sha1', $inputText, $keyString)
