首先:
资料准备:

      水印图片 28*28         png格式        公司logo
      高清图片 108*108     png格式       公司logo

      1.在微信开放平台 https://open.weixin.qq.com/中填写基本信息,
      2.完成邮箱验证,
      3.并完善开发者资料,注册成为开发者。
      4.在“账号中心”完成开发者资质认证。
      5.进入微信开放平台管理中心网站应用,点击“创建应用”按钮。
      6.填写基本信息,完成点击下一步
      7.填写平台信息
        应用签名:可在微信开发平台的资源中心》》资源下载》》中下载“签名生成工具”,用户获取已经安装到手机的第三方应用的签名。输入应用包名,即可获得该应用的签名值。
      8.提交审核后,在7个工作日内腾讯将给出审核结果。(通常较快,几个小时就可反馈结果)

获取AppID,AppSecret,之后的处理

需要在你想加的网站登录页给一个链接:<a href="https://open.weixin.qq.com/connect/qrconnect?appid=your appid &redirect_uri=http://www.sunmil.cn/passport-linshi.html&response_type=code&scope=snsapi_login&state=STATE#wechat_redirect">微信登录</a>

处理微信登录开始

定义appid appsecert

    private $appid = "your appid";
    private $appsecert = "your appsecert";
    private $redirect_uri = "http://www.sunmil.cn/wxGetCode";

绑定账号页面

  public function weixin(){
        //链接数据库
        $link = mysqli_connect(DB_HOST, DB_USER,DB_PASSWORD,DB_NAME ) or die('数据库连接失败4');
        $link = mysqli_connect('127.0.0.1', 'root','root', 'ec') or die('数据库连接失败');
        mysqli_set_charset($link,'utf8');

        //接收openid
        $openid = $_COOKIE['openid'];

        $sql = "select * from sdb_trustlogin_trustinfo where openid = '$openid' ";
        $res = mysqli_query($link, $sql);
        $row = mysqli_fetch_assoc($res);

        $this->pagedata['realname'] = $row['realname'];
        $this->pagedata['avatar'] =  $row['avatar'];

        $this->page("site/passport/weixin.html");

    }

当第一次微信登录,处理绑定账号页面

    public function handle($url=null){       
    // $url = "http://www.sunmil.cn";
         //链接数据库
        $link = mysqli_connect(DB_HOST, DB_USER,DB_PASSWORD,DB_NAME ) or die('数据库连接失败3');
            mysqli_set_charset($link,'utf8');            $post = utils::_filter_input($_POST);        
            $userData = array(            'login_account' => $post['uname'],'login_password' => $post['password']
        );        
        $member_id = kernel::single('pam_passport_site_basic')->login($userData,$post['verifycode'],$msg);        
        $b2c_members_model = $this->app->model('members');       
        $member_point_model = $this->app->model('member_point');        
        $member_data = $b2c_members_model->getList( 'member_lv_id,experience,point', array('member_id'=>$member_id) );        
        $member_data = $member_data[0];        
        $member_data['order_num'] = $this->app->model('orders')->count( array('member_id'=>$member_id) );  

        $b2c_members_model->update($member_data,array('member_id'=>$member_id));        
        $this->userObject->set_member_session($member_id);        
        $this->bind_member($member_id);        
        $this->set_cookie('loginName',$post['uname'],time()+31536000);//用于记住密码
        // setCartNum()需要传入一个参数
        $aCart = array();        
        $this->app->model('cart_objects')->setCartNum($aCart);        
        $url = $this->userPassport->get_next_page('pc');        
        if( !$url ){            
        $url = kernel::single('b2c_frontpage')->gen_url(array('app'=>'b2c','ctl'=>'site_member','act'=>'index'));
        }        
        //查询数据库
        $uname = $_POST['uname'];        
        $sql = "select * from sdb_pam_members where password_account = '$uname' ";        
        $res = mysqli_query($link, $sql);        
        $row = mysqli_fetch_assoc($res);        
        $member_id = $row['member_id'];        
        //链接数据库,插入数据
        $openid =  $_COOKIE['openid'];        
        $sql = "update sdb_trustlogin_trustinfo set member_id = ('{$member_id}')  where openid = '{$openid}'";        
        $res = mysqli_query($link, $sql); 

        if($res && mysqli_affected_rows($link) > 0){ 
            //删除cookie
            setcookie("openid", $openid, time()-3600);
            kernel::single('pam_lock')->flush_lock($member_id);            
            $this->splash('success',$url,app::get('b2c')->_('登录成功'),true); 
        }else{            
        echo '失败了';
        }
    }

处理绑定注册页面

public function weixin1(){          
//链接数据库
        $link = mysqli_connect(DB_HOST, DB_USER,DB_PASSWORD,DB_NAME ) or die('数据库连接失败2');
        mysqli_set_charset($link,'utf8');        
        //接收openid
        $openid = $_COOKIE['openid'];        
        $sql = "select * from sdb_trustlogin_trustinfo where openid = '$openid' ";        
        $res = mysqli_query($link, $sql);        
        $row = mysqli_fetch_assoc($res);        
        $this->pagedata['realname'] = $row['realname'];        
        $this->pagedata['avatar'] =  $row['avatar'];        
        $this->page("site/passport/weixin1.html");

curl模拟get请求

        curl_setopt($curlobj, CURLOPT_URL, $url);
        curl_setopt($curlobj, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($curlobj, CURLOPT_SSL_VERIFYHOST, FALSE);        $output = curl_exec($curlobj);
        curl_close($curlobj);        return $output;
    }

处理微信登录结束

就可以实现微信登录了,当然了,一个简单熟悉微信第三登录的demo,有机会用tp框架分装完善一个完整的微信第三方登录。

欢迎留言,大家一起讨论。

以上就是微信第三方登录demo 的详细内容,更多请关注其它相关文章!
