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logo1.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：微信登录

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");  }

绑定注册页面

public function handle1($url=null){    //链接数据库    $link = mysqli_connect(DB_HOST, DB_USER,DB_PASSWORD,DB_NAME ) or die('数据库连接失败1');    mysqli_set_charset($link,'utf8');    $_POST = utils::_filter_input($_POST);        $saveData = $this->userPassport->pre_signup_process($_POST);    if( $member_id = $this->userPassport->save_members($saveData,$msg) ){      $this->userObject->set_member_session($member_id);      $this->bind_member($member_id);      foreach(kernel::servicelist('b2c_save_post_om') as $object) {        $object->set_arr($member_id, 'member');        $refer_url = $object->get_arr($member_id, 'member');      }      /*注册完成后做某些操作! begin*/      foreach(kernel::servicelist('b2c_register_after') as $object) {        $object->registerActive($member_id);      }      /*end*/      $data['member_id'] = $member_id;      $data['uname'] = $saveData['pam_account']['login_account'];      $data['passwd'] = $_POST['pam_account']['psw_confirm'];      $data['email'] = $_POST['contact']['email'];      $data['refer_url'] = $refer_url ? $refer_url : '';      $data['is_frontend'] = true;      $obj_account=$this->app->model('member_account');      $obj_account->fireEvent('register',$data,$member_id);      if(!strpos($_SESSION['pc_next_page'],'cart')){        $url = $this->gen_url(array('app'=>'b2c','ctl'=>'site_passport','act'=>'sign_tips'));      }else{        $url = $_SESSION['pc_next_page'];      }      //会员注册成功，处理member_id 开始      $login_name = $_POST["pam_account"]["login_name"];      $sql = "select member_id from sdb_pam_members where password_account = '{$login_name}'";      // echo $sql;      $res = mysqli_query($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);        $this->splash('success',$url,app::get('b2c')->_('注册成功'),$ajax_request);        }       //会员注册成功，处理member_id 结束      $this->splash('failed',$back_url,app::get('b2c')->_('注册失败'),$ajax_request);    }  }

临时页面

public function linshi(){    $code = $_GET['code'];    $state = $_GET['state'];    if($state === 'STATE'){      $this->loginWeixin($code);    }elseif($state === 'wxBind'){      $this->bindWeixin($code);    }else{      return redirect("http://www.sunmil.cn");    }  }

loginWeixin

private function loginWeixin($code){    //链接数据库    $link = mysqli_connect('127.0.0.1', 'root','root', 'ec') or die('数据库连接失败');    mysqli_set_charset($link,'utf8');    $appid = $this->appid;    $appsecert = $this->appsecert;    $url = "https://api.weixin.qq.com/sns/oauth3/access_token?appid=".$appid."&secret=".$appsecert."&code=".$code."&grant_type=authorization_code";    //curl模拟get请求，获取结果    $res = $this->http_curl($url);    //转化为数组    $result = json_decode($res,true);    $openid = $result['openid'];    //openid存在，直接登录，openid不存在，先注册再登录    $sql = "select openid from sdb_trustlogin_trustinfo";    $res = mysqli_query($link, $sql);    $row = mysqli_fetch_all($res);          //foreach 判断    foreach ($row As $v) {      if(in_array($openid,$v,true)){        //缺少登录信息        $sql = "select member_id from sdb_trustlogin_trustinfo where openid = '{$openid}'";        //查出member_id        $res = mysqli_query($link, $sql);        $row = mysqli_fetch_assoc($res);        $member_id = $row['member_id'];        //查出会员信息        $sql = "select * from sdb_pam_members where member_id = '{$member_id}'";        $res = mysqli_query($link, $sql);        $row = mysqli_fetch_assoc($res);        $login_name = $row['login_account'];        //存入cookie         setcookie('UNAME',$login_name, time()+360000);        echo "";        exit;      }    }    $access_token = $result['access_token'];    //获取用户基本信息    $getInfoUrl = "https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN";    $userInfo = $this->http_curl($getInfoUrl);    $trustinfo = json_decode($userInfo);    //判断trustinfo表里面是否存在该条数据    $openid   =  $trustinfo->openid;    $nickname  =  $trustinfo->nickname;     $sex    =  $trustinfo->sex;     $city    =  $trustinfo->city;     $province  =  $trustinfo->province;     $country  =  $trustinfo->country;     $avatar   =  $trustinfo->headimgurl;    $trust_source = 'trustlogin_plugin_weixin';    //连接数据库，插入数据    $sql = "insert into sdb_trustlogin_trustinfo (openid,realname,avatar,gender,province,city,trust_source) values ('{$openid}','{$nickname}','{$avatar}','{$sex}','{$province}','{$city}','{$trust_source}')";    $res = mysqli_query($link, $sql);     if($res && mysqli_affected_rows($link) > 0){        //存入cookie       setcookie('openid',$openid, time()+3600);      header("Location:http://www.sunmil.cn/passport-weixin.html");    }else{      echo '失败了';    }    }

curl模拟get请求

private function http_curl($url){    $curlobj = curl_init();    curl_setopt($curlobj, CURLOPT_URL, $url);    curl_setopt($curlobj, CURLOPT_RETURNTRANSFER, 1);    curl_setopt($curlobj, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($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。
