PHP获取新浪微博token
最近在做采集微博的功能，由于要自动采集，所以必须获得最终的用户的token，获取了这个token以后就可以为所欲为啦！
贴代码
$s = new SaeTOAuthV2 ( WB_AKEY, WB_SKEY);
//准备post数据
$post ['action'] = 'login';
//$post ['display'] = 'default';
//$post ['withOfficalFlag'] = 0;
//$post ['quick_auth'] = null;
//$post ['withOfficalAccount'] = '';
//$post ['scope'] = '';
//$post ['ticket'] = '';
//$post ['isLoginSina'] = '';
//$post ['isLoginSina'] = 'code';
//regCallback|appkey62需要预先请求一次拿到
//$post ['regCallback'] = $match_regCallback[1];
//这里不用urlencode,http_build_query会自动处理
$post ['redirect_uri'] = WB_CALLBACK_URL;
$post ['client_id'] = WB_AKEY;
//$post ['appkey62'] = $match_appkey[1];
//$post ['state'] = '';
//$post ['verifyToken'] = null;
//$post ['from'] = '';
$post ['userId'] = '*******';//测试用户名
$post ['passwd'] = '*******';//测试密码,不要有！@￥%……&*（）这些符号，最好全是字符或数字，否则验证会失败
$post = http_build_query($post);
//UA貌似没有也行，保险起见还是加上吧
$UA = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36';
//获取认证URL作为refer
$url = $s->getAuthorizeURL (WB_CALLBACK_URL);
//echo $url."\n";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.weibo.com/oauth2/authorize');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//自动跳转
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $UA);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
//获取最后一个有效的url地址
$token_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
echo $token_url."\n";
curl_close($ch);
$code = preg_match('#code\=(.*)#',$token_url,$match_url);
//找到code
if($code>=1)
{
$code = $match_url[1];
$keys = array();
$keys['code'] = trim($code);
$keys['redirect_uri'] = WB_CALLBACK_URL;
try
{
$token = $s->getAccessToken( 'code', $keys );
} catch (OAuthException $e)
{
die($e->getMessage());
}
return $token;
}else
{
die("code获取失败");
}
思路很简单，直接给 https://api.weibo.com/oauth2/authorize 发送登录信息，通过认证后，他会返回给你一个跳转URL，并带有一个code变量，这个code还是与开发者绑定的。
然后使用这个code，与服务器的 http://open.weibo.com/wiki/Oauth2/authorize 接口通信，返回的才是最终你需要的token，这个token同时与用户绑定，将他保存在session里随时调用！
