我正在尝试设置自己的OAuth提供程序,但现在我一直在签署请求。这是签署的正确方式吗?
function generateSignature($consumerSecret, $requestURI, $requestData, $requestMethod) {
$signature = '';
$signature .= strtoupper($requestMethod) . '&';
$signature .= urlencode($requestURI) . '&';
asort($requestData);
$query = http_build_query($requestData);
$signature .= urlencode($query);
echo oauthHMACsha1($consumerSecret, $signature);
}
function HMACsha1($key, $data) {
$blocksize = 64;
$hashfunc = 'sha1';
if (strlen($key) > $blocksize) $key = pack('H*', $hashfunc($key));
$key = str_pad($key, $blocksize, chr(0x00));
$ipad = str_repeat(chr(0x36), $blocksize);
$opad = str_repeat(chr(0x5c), $blocksize);
$hmac = pack('H*',$hashfunc(($key^$opad).pack('H*', $hashfunc(($key ^ $ipad) . $data))));
return $hmac;
}
function oauthHMACsha1($key, $data) {
return base64_encode(HMACsha1($key, $data));
}
或者它可以更容易/更有效吗?为什么签名很重要?
