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 = $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');

$this->pagedata['avatar'] = $row['avatar'];
$this->page("site/passport/weixin1.html");
}
绑定注册页面
public function handle1($url=null){

mysqli_set_charset($link,'utf8');

临时页面

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。
