导读：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：

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：

处理微信登录开始

定义appid appsecert

绑定账号页面

//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

  $post = utils::_filter_input($_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

//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

$_POST = utils::_filter_input($_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",time()-3600);
    $this->splash('success',app::get('b2c')->_('注册成功'),$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

$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

//链接数据库
$link = mysqli_connect('127.0.0.1','ec') or die('数据库连接失败');
mysqli_set_charset($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='http://www.sunmil.cn'</script>";
    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',time()+3600);
  header("Location:http://www.sunmil.cn/passport-weixin.html");
}else{
  echo '失败了';
}

}

curl模拟get请求

$output = curl_exec($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。
