php实例-微信第三方登录

发表日期：2019-08 文章编辑：小灯浏览次数：1776

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='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。
