[英]Calculate HMAC-SHA1 Signature
我在PHP中獲得了下面的代碼,但是從未經授權的服務器中收到了一個錯誤,因此在計算oauth_signature字段的$ signature時可能會出錯。
未設置任何HTTP標頭。
include_once "oauth-php/library/OAuthStore.php";
include_once "oauth-php/library/OAuthRequester.php";
$key = 'xx'; // this is your consumer key
$secret = 'xx'; // this is your secret key
$req_url = "http://www.sample.com";
$options = array( 'consumer_key' => $key, 'consumer_secret' => $secret);
OAuthStore::instance("2Leg", $options );
$method = "POST";
$ params = array('oauth_consumer_key'=> $ key,'oauth_signature_method'=>'HMAC-SHA1','oauth_timestamp'=> time(),'oauth_nonce'=> time(),'user_id'=>'1234' );
$post_string = '';
foreach($params as $key => $value) {
$post_string .= $key.'='.($value).'&';
}
$post_string = rtrim($post_string, '&');
$base_string = urlencodeRFC3986($post_string);
$signature = base64_encode(hash_hmac('sha1', $base_string, $secret, true));
$params['oauth_signature'] = $signature;
try {
$request = new OAuthRequester($req_url, $method, $params);
$result = $request->doRequest();
var_dump($result);
}
catch(OAuthException2 $e)
{
var_dump($e);
}
function urlencodeRFC3986($string)
{
return str_replace('%7E', '~', rawurlencode($string));
}
一些東西:
1)不要將'oauth_signature_method'
設置為array('HMAC-SHA1')
。 只需使用'HMAC-SHA1'
,否則您將在帖子字符串中使用oauth_signature_method=Array
結束。
2)在計算完簽名后,請勿在參數列表中包含oauth_signature
。 有關更多詳細信息,請參閱此問題: https : //stackoverflow.com/questions/9986533/what-does-oauth-signature-sign
您應該以如下形式結束:
$params = array(
'oauth_consumer_key' => $key,
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp' => time(),
'oauth_nonce' => time(),
'user_id' => '1234'
);
$post_string = '';
foreach($content as $key => $value)
{
$post_string .= $key.'='.($value).'&';
}
$post_string = rtrim($post_string, '&');
$base_string = urlencodeRFC3986($post_string);
$signature = base64_encode(hash_hmac('sha1', $base_string, $secret, true));
$params['oauth_signature'] = $signature;
