微信扫码网站自动登录的原是还是比较简单的,只要各位知道相互的原理就可以实现了,下面我们来看两个例子,我相信各位看了这两个例子肯定知道怎么来做了。

magento 微信扫码网站自动登录

案例仿照了微信联合登陆的做法,微信联合登陆介绍:

https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&lang=zh_CN

查看授权后接口调用(UnionID),不难发现填写回调地址,用户确认登陆pc端即可跳转

获取UnionID方法

public function wcallbackAction(){
 
$code = $_GET['code'];
$state = $_GET['state'];
$setting = include CONFIG_PATH . 'setting.php';
$appid=$setting['weixin']['appid'];
$appsecret=$setting['weixin']['appsecret'];
 
if (empty($code)) $this->showMessage('授权失败');
try{
 
$token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code';
 
$token = json_decode($this->https_request($token_url));
 
}catch(Exception $e)
{
print_r($e);
}
 
if (isset($token->errcode)) {
echo '

错误:

'.$token->errcode;
echo '

错误信息:

'.$token->errmsg;
exit;
}
 
$access_token_url = 'https://api.weixin.qq.com/sns/oauth2/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token;
//转成对象
$access_token = json_decode($this->https_request($access_token_url));
if (isset($access_token->errcode)) {
echo '

错误:

'.$access_token->errcode;
echo '

错误信息:

'.$access_token->errmsg;
exit;
}
$user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token->access_token.'&openid='.$access_token->openid.'&lang=zh_CN';
//转成对象
$user_info = json_decode($this->https_request($user_info_url));
if (isset($user_info->errcode)) {
echo '

错误:

'.$user_info->errcode;
echo '

错误信息:

'.$user_info->errmsg;
exit;
}
//打印用户信息
// echo '
';<br>
// print_r($user_info);<br>
// echo '
Copy after login
Copy after login
';
 
//获取unionid
 
$uid=$user_info->unionid;
 
}
 
//用户操作处理 分为再次登录和第一次登陆
 
$sql="select h_user_id from dtb_user_binded as t1 left join dtb_user_weixin as t2 on t1.u_id=t2.id where t1.u_type='".
User::$arrUtype['weixin_num_t']."' and t2.openid='$user_info->unionid'";
$h_user_id = Core_Db::getOne($sql);
if(!empty($h_user_id)){//该weixin号再次登录
 
}{//该weixin号第一次登录
 
}

php 微信扫码 pc端自动登陆注册


用的接口scope 是snsapi_userinfo,微信登陆一个是网页授权登陆,另一个是微信联合登陆

网页授权登陆:http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html

微信联合登陆:https://open.weixin.qq.com/cgi-bin/frame?t=home/web_tmpl&lang=zh_CN

一:首先把微信链接带个标识生成二维码

比如链接为 https://open.weixin.qq.com/connect/oauth2/authorize?appid=’.$appid.’&redirect_uri=’.$url.’&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect’  我们可以在state上做文章,因为state你传入什么微信那边返回什么

可以作为服务器与微信段的一个标识


public function creatqrAction(){

if($_GET['app']){
$wtoken=$_COOKIE['wtoken'];
$postdata=$_SESSION['w_state'];
if($wtoken){
$postdata=$wtoken;
}
include CONFIG_PATH . 'phpqrcode/'.'phpqrcode.php';
$sh=$this->shar1();
$value="https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx138697ef383a9167&redirect_uri=http://www.xxx.net/login/wcallback&response_type=code&scope=snsapi_userinfo&state=".$postdata."&connect_redirect=1#wechat_redirect";

$errorCorrectionLevel = "L";

$matrixPointSize = "5";

QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize);
}

}

此时生成了二维码 state是标识,phpqrcode可以在文章末尾下载,这样我们设置了回调地址http://www.xxx.net/login/wcallback

就可以在wcallback方法里面处理数据 插入用户 生成session,跳转登陆,pc端可以设置几秒钟ajax请求服务器,一旦获取到了

state,即实现调整,微信浏览器里处理完后可以关闭窗口,微信js可实现


document.addEventListener('WeixinJSBridgeReady', function onBridgeReady() {
WeixinJSBridge.call('closeWindow');

}, false);

也可以授权登陆成功后跳转到微信服务号关注页面


header("Location: weixin://profile/gh_a5e1959f9a4e");

wcallback方法做处理登陆


$code = $_GET['code'];
$state = $_GET['state'];
$setting = include CONFIG_PATH . 'setting.php';
$appid=$setting['weixin']['appid'];
$appsecret=$setting['weixin']['appsecret'];

if (empty($code)) $this->showMessage('授权失败');
try{

$token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code';

$token = json_decode($this->https_request($token_url));

}catch(Exception $e)
{
print_r($e);
}

if (isset($token->errcode)) {
echo '

错误:

'.$token->errcode;
echo '

错误信息:

'.$token->errmsg;
exit;
}

$access_token_url = 'https://api.weixin.qq.com/sns/oauth2/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token;
//转成对象
$access_token = json_decode($this->https_request($access_token_url));
if (isset($access_token->errcode)) {
echo '

错误:

'.$access_token->errcode;
echo '

错误信息:

'.$access_token->errmsg;
exit;
}
$user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token->access_token.'&openid='.$access_token->openid.'&lang=zh_CN';
//转成对象
$user_info = json_decode($this->https_request($user_info_url));
if (isset($user_info->errcode)) {
echo '

错误:

'.$user_info->errcode;
echo '

错误信息:

'.$user_info->errmsg;
exit;
}
//打印用户信息
// echo '
';<br>
// print_r($user_info);<br>
// echo '
Copy after login
Copy after login
';
