php實現新浪微博受權登陸

第一步：

前往微博開放平臺申請應用，地址：http://open.weibo.com/，須要企業帳號並審覈經過。（微博受權審覈是須要在你的web或者app上須要有微博登錄的按鈕，否者審覈不會經過）

拿到App Key和App Secret以後就能夠開始調取接口。

 

第二步：

用戶表新加字段存儲微博返回信息，如圖：

 

第三步：

去官方下載一個sdk，下載地址 https://github.com/xiaosier/libweibo，直接上代碼：

/**
     * 微博受權登陸
     */
    public function weiboLogin(){
        $app_key = "3495468843";    //app key

        $app_secret = "7d26eeb3fd46815a1d1ecda1cd786d29";    //app secert

        $my_url = "http://".$_SERVER['HTTP_HOST']."/Home/User/weiboLogin";

        //第一步：用戶贊成受權，獲取code
        $code = $_REQUEST["code"];//存放code
        if(empty($code)){
            $url = "https://api.weibo.com/oauth2/authorize?client_id=".$app_key."&response_type=code&redirect_uri=". urlencode($my_url);

            echo("<script> top.location.href='" . $url . "'</script>");
        }

        //第二步：用code換取Access Token
        if(!empty($code)){
            //include_once( 'saetv2.ex.class.php' );
            vendor("Weibo.saetv2"); //引入微博sdk
            $o = new \SaeTOAuthV2( $app_key , $app_secret );

            $keys = array();
            $keys['code'] = $code;
            $keys['redirect_uri'] = $my_url;
            try {
                $token = $o->getAccessToken( 'code', $keys ) ;

            }
            catch (\OAuthException $e) {

            }

            //第三步，用Access Token獲取帳號信息
            if ($token) {
                //$_SESSION['token'] = $token;
                //setcookie( 'weibojs_'.$o->client_id, http_build_query($token) );
                $c = new \saetclientv2($app_key,$app_secret, $token['access_token']);
                $ms =$c->home_timeline();
                $uid_get = $c->get_uid();
                $uid = $uid_get['uid'];
                $usr_info=$c->show_user_by_id($uid); //微博sdk方法獲取用戶的信息

                $m = M("Member");
                $data = array();
                $data['sex']              = $usr_info['gender']=='m'?1:2;
                $data['province']      = $usr_info['province'];
                $data['city']             = $usr_info['city'];
                $data['person_name']   = $usr_info['name'];
                $data['xl_openid']     = $usr_info['idstr'];
                $data['xl_img']        = $usr_info['profile_image_url'];
                $data['addtime']       = date("Y-m-d H:i:s", time());
                $data['person_img']       = $usr_info['profile_image_url'];
                $data['signtime']       = date("Y-m-d H:i:s", time());

                $user = M("Member")->where(array("xl_openid"=> $usr_info['idstr']))->find();
                if($user){
                    $res = M("Member")->where(array("xl_openid"=> $usr_info['idstr']))->setField("signtime", date("Y-m-d H:i:s", time()));
                    if($res){
                        //登陸成功業務邏輯

                    }else{
                        $this->error("操做異常，拒絕訪問！", U('user/login'));
                    }
                }else{
                    $res=$m->add($data);
                    if($res){
                        //登陸成功業務邏輯

                    }else{
                        $this->error("操做異常，拒絕訪問！", U('user/login'));
                    }
                }

            }else {
                $this->error("受權失敗。", U('user/login'));
            }
        }

    }
