计算HMAC-SHA1签名

我在PHP中获得了下面的代码,但是我的服务器收到了一个未经授权的错误,因此在计算oauth_signature字段的$ signature时出错了。

我没有设置任何HTTP标头。

        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'=> $关键,                         'oauth_signature_method'=> 'HMAC-SHA1',                         'oauth_timestamp'=>时间(),                         'oauth_nonce'=>时间(),                         '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)); 
}

答案 0 :(得分:1)

一些事情:

1)不要将'oauth_signature_method'设为array('HMAC-SHA1')。只需使用'HMAC-SHA1',否则您最终会在帖子字符串中使用oauth_signature_method=Array

2)在 之后,不要在参数列表中包含oauth_signature。有关详细信息,请参阅此问题:https://stackoverflow.com/questions/9986533/what-does-oauth-signature-sign

你应该得到类似的东西:

$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;
