Php 计算HMAC-SHA1签名

Php 计算HMAC-SHA1签名,php,Php,我在PHP中得到了下面的代码,但是从我的服务器得到了一个错误,没有得到授权,所以我可能在计算oauth_签名字段的$signature时出错 我没有设置任何HTTP头 include_once "oauth-php/library/OAuthStore.php"; include_once "oauth-php/library/OAuthRequester.php"; $key = 'xx'; // this is your consumer k

我在PHP中得到了下面的代码,但是从我的服务器得到了一个错误,没有得到授权,所以我可能在计算oauth_签名字段的$signature时出错

我没有设置任何HTTP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";  
$params=数组( “oauth_consumer_key”=>$key, “oauth_签名_方法”=>“HMAC-SHA1”, 'oauth_timestamp'=>time(), 'oauth_nonce'=>time(), “用户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)); 
}
有几件事:

1) 不要将
“oauth\u签名\u方法”设置为
数组('HMAC-SHA1')
。只需使用
'HMAC-SHA1'
,否则您的帖子字符串中就会出现
oauth\u signature\u method=Array

2) 在计算签名之前,不要将
oauth_签名
包含在参数列表中。有关更多详细信息,请参见此问题:

你应该以这样的方式结束:

$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;
