微信第三方登录(原生)demo【必看篇】

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。

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='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',$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。
