雅虎在使用OAuth时返回“signature_invalid”

Question

我试图让我的网站用户使用他们的Yahoo/Gmail帐户登录。
Gmail正常。但在雅虎我有以下的PHP代码片段：

 
$this->options = array('consumer_key' => 'My Key from Yahoo', 
    'consumer_secret' => 'My Secret ', 
    'server_uri' => 'https://www.yahoo.com', 
    'request_token_uri'=> 'https://api.login.yahoo.com/oauth/v2/get_request_token', 
    'authorize_uri' => 'https://api.login.yahoo.com/oauth/v2/request_auth', 
    'access_token_uri'=> 'https://api.login.yahoo.com/oauth/v2/get_token',); 
$getAuthTokenParams = array(
    'xoauth_lang_pref' => 'en-us', 
    'oauth_callback' => $this->callback_url);//callback to my page 
$tokenResultParams = OAuthRequester::requestRequestToken($this->options['consumer_key'], 0, $getAuthTokenParams); 

现在雅虎给出

 
HTTP/1.1 401 Forbidden 
Date: Wed, 27 Jul 2011 09:12:19 GMT 
P3P: policyref="http://info.yahoo.com/w3c/p3p.xml", CP="CAO DSP COR CUR ADM DEV TAI PSA PSD IVAi IVDi CONi TELo OTPi OUR DELi SAMi OTRi UNRi PUBi IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE LOC GOV" 
WWW-Authenticate: OAuth oauth_problem=signature_invalid 
Connection: close

oauth_problem=signature_invalid 

在 https://developer.apps.yahoo.com/projects

我选择了：

 
delicious social bookmarking (read/write) 
Contacts (read) 
Social Directory (read/write) 

，有没有人遇到同样的问题？我做错了什么？
感谢您的帮助

正如我昨天发现的，雅虎的令牌非常庞大。意思是oauth-php存储不好，所以你得到了不好的签名。这里是我对该问题的解决方案：How to use the Yahoo! API with the oauth-php library?
