对于那些愿意使用我强烈推荐的 Zend_OAuth_Consumer 解决方案的人，因为它处理了处理 OAuth 请求所需的所有琐碎步骤，以及响应响应后的所有困难过程，这是我的工作代码：

1）建立消费者实例：

$consumer = new Zend_Oauth_Consumer(array(
    'callbackUrl' => FLICKR_REDIRECT_URL /* from my app settings */,
    'siteUrl' => 'http://www.flickr.com/services/oauth',
    'consumerKey' => FLICKR_API_KEY,
    'consumerSecret' => FLICKR_API_SECRET,
    'requestTokenUrl' => FLICKR_REQUEST_TOKEN_URL /* www.flickr.com/services/oauth/request_token */,
    'accessTokenUrl' => FLICKR_ACCESS_TOKEN_URL /* www.flickr.com/services/oauth/access_token */,
    'authorizeUrl' => FLICKR_AUTHORIZE_URL /* www.flickr.com/services/oauth/authorize */
));

2）获取请求令牌并将其存储在 $_SESSION 变量中（或使用您想要的任何其他存储机制）。确保将返回对象序列化为会话变量的字符串：

$token = $consumer->getRequestToken();

$_SESSION['FLICKR_REQUEST_TOKEN'] = serialize($token);

3）如果我在设置权限时遇到问题，请使用消费者实例的方法进行重定向，并在此时设置您的权限（即“读取”、“写入”、“删除”等）：

$consumer->redirect(array("perms" => FLICKR_API_PERMS /* 'read', 'write', 'delete', etc... */));

4) 在您重定向到的页面（即 FLICKR_REDIRECT_URL）上，创建一个新的消费者实例，现在获取一个访问令牌，将其存储在 $_SESSION 中，然后取消设置会话请求令牌变量：

$consumer = new Zend_Oauth_Consumer(array(
    'callbackUrl' => FLICKR_REDIRECT_URL /* from my app settings */,
    'siteUrl' => 'http://www.flickr.com/services/oauth',
    'consumerKey' => FLICKR_API_KEY,
    'consumerSecret' => FLICKR_API_SECRET,
    'requestTokenUrl' => FLICKR_REQUEST_TOKEN_URL /* www.flickr.com/services/oauth/request_token */,
    'accessTokenUrl' => FLICKR_ACCESS_TOKEN_URL /* www.flickr.com/services/oauth/access_token */,
    'authorizeUrl' => FLICKR_AUTHORIZE_URL /* www.flickr.com/services/oauth/authorize */
));

$token = $consumer->getAccessToken($_GET, unserialize($_SESSION['FLICKR_REQUEST_TOKEN']));

$_SESSION['FLICKR_ACCESS_TOKEN'] = serialize($token);

$_SESSION['FLICKR_REQUEST_TOKEN'] = null;

5）此时您应该能够向 Flickr 发出授权请求：

$token = unserialize($_SESSION['FLICKR_ACCESS_TOKEN']);
$client = $token->getHttpClient(array(
    'callbackUrl' => FLICKR_REDIRECT_URL /* from my app settings */,
    'siteUrl' => 'http://www.flickr.com/services/oauth',
    'consumerKey' => FLICKR_API_KEY,
    'consumerSecret' => FLICKR_API_SECRET,
    'requestTokenUrl' => FLICKR_REQUEST_TOKEN_URL /* www.flickr.com/services/oauth/request_token */,
    'accessTokenUrl' => FLICKR_ACCESS_TOKEN_URL /* www.flickr.com/services/oauth/access_token */,
    'authorizeUrl' => FLICKR_AUTHORIZE_URL /* www.flickr.com/services/oauth/authorize */
));
$client->setUri("http://api.flickr.com/services/rest/");
$client->setMethod(Zend_Http_Client::GET);
$client->setParameterGet("method", "flickr.contacts.getList");
$client->setParameterGet("api_key", FLICKR_API_KEY);
$response = $client->request();

header('Content-Type: text/xml');
echo $response->getBody();

我希望这对某人有很大帮助。代码业力 =)
