微信网站应用扫码登陆
1、js二维码code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>微信扫码登陆</title>
<script type="text/javascript" src="/app/static/wxLogin.js"></script>
</head>
<body>
<div id="login_container">
</div>
<script type="text/javascript">
var obj = new WxLogin({
self_redirect:true,
id:"login_container",
appid: "",
scope: "snsapi_login",
redirect_uri: "{$redirect_uri}",
state: "",
style: "black",
href: "LmltcG93ZXJCb3ggLnFyY29kZSB7d2lkdGg6IDIwMHB4O30KLmltcG93ZXJCb3ggLnRpdGxlIHtkaXNwbGF5OiBub25lO30KLmltcG93ZXJCb3ggLmluZm8ge3dpZHRoOiAyMDBweDt9Ci5zdGF0dXNfaWNvbiB7ZGlzcGxheTogbm9uZX0KLmltcG93ZXJCb3ggLnN0YXR1cyB7dGV4dC1hbGlnbjogY2VudGVyO30g"
});
</script>
</body>
</html>
2、接受code，生成openid
//获取微信二维码扫码登陆
$tokens="https://api.weixin.qq.com/sns/oauth2/access_token?appid=&secret=&code={$code}&grant_type=authorization_code";
$this->oLogAct->add("微信扫码登陆获取二维码token地址" . json_encode($tokens));
$tokens=$this->setGet($tokens);
$this->oLogAct->add("微信扫码登陆获取二维码token信息" . json_encode($tokens));
if (empty($tokens)) {
return self::setMsg(500, '登录失败!');
}
$openid=base64_encode($this->encryptData($tokens['openid']));
