php实现新浪微博授权登录

Posted 2020-09-28 从此以往

第一步：

前往微博开放平台申请应用，地址：http://open.weibo.com/，需要企业账号并审核通过。（微博授权审核是需要在你的web或者app上需要有微博登陆的按钮，否者审核不会通过）

拿到App Key和App Secret之后就可以开始调取接口。

 

第二步：

用户表新加字段存储微博返回信息，如图：

 

第三步：

去官方下载一个sdk，下载地址 https://github.com/xiaosier/libweibo，直接上代码：

/**
     * 微博授权登录
     */
    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：用户同意授权，获取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换取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获取账号信息
            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方法获取用户的信息

                $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){
                        //登录成功业务逻辑

                    }else{
                        $this->error("操作异常，拒绝访问！", U(\'user/login\'));
                    }
                }else{
                    $res=$m->add($data);
                    if($res){
                        //登录成功业务逻辑

                    }else{
                        $this->error("操作异常，拒绝访问！", U(\'user/login\'));
                    }
                }

            }else {
                $this->error("授权失败。", U(\'user/login\'));
            }
        }

    }
