php实例-微信第三方登录

下面小编就为大家带来一篇微信第三方登录(原生)demo【必看篇】。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧

在一家ecstore二开公司有一段时间了，公司希望往自己研发产品上面走，一直在培养新人。

最近要自己去微信登录，自己就在ectore的框架基础上，写的原生微信第三方登录以此来熟悉微信第三方登录，在ecstore上面去写。

一个简单的demo，不是很好，分享给大家，希望能给想做微信第三方登录的朋友带来思路...

首先：

资料准备：

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" rel="external nofollow" >微信登录</a>
<br><br>

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;
    $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$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 "<script>window.location.href=&#39;http://www.sunmil.cn&#39;</script>";
        exit;
      }
    }

    $access_token = $result[&#39;access_token&#39;];
    //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 = &#39;trustlogin_plugin_weixin&#39;;
    //连接数据库，插入数据
    $sql = "insert into sdb_trustlogin_trustinfo (openid,realname,avatar,gender,province,city,trust_source) values (&#39;{$openid}&#39;,&#39;{$nickname}&#39;,&#39;{$avatar}&#39;,&#39;{$sex}&#39;,&#39;{$province}&#39;,&#39;{$city}&#39;,&#39;{$trust_source}&#39;)";

      header("Location:http://www.sunmil.cn/passport-weixin.html");
    }else{
      echo &#39;失败了&#39;;
    }  
  }

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。
