微信第三方登录(原生)demo详解

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： 水印图片 28*28 png格式 公司logo 高清图片 108*108 png格式 公司logo 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://wsw.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://wsw.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://wsw.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://wsw.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://wsw.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://wsw.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
