使用微信接口,無(wú)論是自動(dòng)登錄還是微信支付我們首先需要獲取的就是openid,獲取openid的方式有兩種,一種是在關(guān)注的時(shí)候進(jìn)行獲取,這種訂閱號(hào)就可以獲取的到,第二種是通過(guò)網(wǎng)頁(yè)授權(quán)獲取,這種獲取需要的是認(rèn)證服務(wù)號(hào)。
今天我要說(shuō)的是第二種網(wǎng)頁(yè)授權(quán)獲取openid。下面是我寫(xiě)的一個(gè)關(guān)于獲取openid的類(lèi)
?php /** * 微信授權(quán)相關(guān)接口 * * @link http://www.phpddt.com */ class Wchat { private $app_id = 'wx444444444444'; private $app_secret = '77777777'; private $state='aaaa'; /** * 獲取微信授權(quán)鏈接 * * @param string $redirect_uri 跳轉(zhuǎn)地址 * @param mixed $state 參數(shù) */ public function get_authorize_url($redirect_uri = '', $state = '') { $redirect_uri = urlencode($redirect_uri); return "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$this->app_id}redirect_uri={$redirect_uri}response_type=codescope=snsapi_userinfostate={$state}#wechat_redirect"; } /** * 獲取微信openid */ public function getOpenid($turl) { if (!isset($_GET['code'])){ //觸發(fā)微信返回code碼 $url=$this->get_authorize_url($turl, $this->state); Header("Location: $url"); exit(); } else { //獲取code碼,以獲取openid $code = $_GET['code']; $access_info = $this->get_access_token($code); return $access_info; } } /** * 獲取授權(quán)token網(wǎng)頁(yè)授權(quán) * * @param string $code 通過(guò)get_authorize_url獲取到的code */ public function get_access_token($code = '') { $appid=$this->app_id; $appsecret=$this->app_secret; $token_url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$appid."secret=".$appsecret."code=".$code."grant_type=authorization_code"; //echo $token_url; $token_data = $this->http($token_url); // var_dump( $token_data); if($token_data[0] == 200) { $ar=json_decode($token_data[1], TRUE); return $ar; } return $token_data[1]; } public function http($url, $method='', $postfields = null, $headers = array(), $debug = false) { $ci = curl_init(); /* Curl settings */ curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($ci, CURLOPT_TIMEOUT, 30); curl_setopt($ci, CURLOPT_RETURNTRANSFER, true); switch ($method) { case 'POST': curl_setopt($ci, CURLOPT_POST, true); if (!empty($postfields)) { curl_setopt($ci, CURLOPT_POSTFIELDS, $postfields); $this->postdata = $postfields; } break; } curl_setopt($ci, CURLOPT_URL, $url); curl_setopt($ci, CURLOPT_HTTPHEADER, $headers); curl_setopt($ci, CURLINFO_HEADER_OUT, true); $response = curl_exec($ci); $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE); if ($debug) { echo "=====post data======\r\n"; var_dump($postfields); echo '=====info=====' . "\r\n"; print_r(curl_getinfo($ci)); echo '=====$response=====' . "\r\n"; print_r($response); } curl_close($ci); return array($http_code, $response); } } ?>
getOpenid($turl)這個(gè)方法就是獲取openid的方法。前端調(diào)用代碼如下:
$openid=isset($_COOKIE['openid'])?$_COOKIE['openid']:''; if(empty($openid)) { $wchat=new wchat(); $t_url='http://'.$_SERVER['HTTP_HOST'].'/user.php?act=register'; $info=$wchat->getOpenid($t_url); if($info){ $openid=$info['openid']; setcookie('openid',$openid,time()+86400*30); } }
以上就是我總結(jié)的獲取openid的方法啦。
