导读:在设计博客类站点时,有时会需要在发布文章时同步发布在微博上。本文阐述了实现该功能的基本方式。
include_once( 'sina_config.php' ); include_once( 'saetv2.ex.class.php' ); //获取到授权的url $o = new SaeTOAuthV2( WB_AKEY , WB_SKEY ); $code_url = $o->getAuthorizeURL( WB_CALLBACK_URL ); //post或get方式调用该url,取得授权;授权完成后,新浪会调用我们这边传过去的回调地址:WB_CALLBACK_URL request()->redirect($code_url);
$o = new SaeTOAuthV2( WB_AKEY , WB_SKEY ); if (isset($_REQUEST['code'])) { $keys = array(); $keys['code'] = $_REQUEST['code']; $keys['redirect_uri'] = WB_CALLBACK_URL; try { $token = $o->getAccessToken( 'code', $keys ) ; } catch (OAuthException $e) { echo "weibo.com get access token err."; LOG_ERR("weibo.com get access token err."); return ; } } if ($token) { //取到授权后的api调用密钥,可用存起来,在有效期内多次调用api接口就不用再授权了 $_SESSION['token'] = $token; $c = new SaeTClientV2( WB_AKEY , WB_SKEY , $_SESSION['token']['access_token'] ); $ret = $c->update( $weiboStr ); //发送微博 if ( isset($ret['error_code']) && $ret['error_code'] > 0 ) { $str = "Weibo.com Send failed. err info:" . $ret['error_code'] . '/' . $ret['error']; LOG_ERR($str); } else { LOG_INFO("Weibo.com Send Success."); } }
//获取当前微博内容(140字) public function getWeibo() { $titleLen = mb_strlen($this->title, 'UTF-8'); //140字除去链接的20个字和省略符;剩115字左右,需要说明的是链接:无论文章的链接多长,在微博里都会被替换成短链接,按短链接的长度来计算字数; $summaryLen = 115 - $titleLen ; $pubPaper = cutstr_html($this->summary); if(mb_strlen($pubPaper, 'UTF-8') >= $summaryLen) $pubPaper = mb_substr($pubPaper,0,$summaryLen,'UTF-8'); $pubPaper = sprintf('【%s】%s...%s', $this->title , $pubPaper , aurl('post/show', array('id' => $this->id))); return $pubPaper; } //完全的去除html标记 function cutstr_html($string) { $string = strip_tags($string); $string = preg_replace ('/n/is', '', $string); $string = preg_replace ('/ | /is', '', $string); $string = preg_replace ('/ /is', '', $string); return $string; }
