我在我的网页中集成了PayPal的身份API。像往常一样，当用户点击login with paypal（JavaScript button）时，它会打开一个新窗口用于登录。但在有效登录后，它会将我重定向到同一个弹出窗口。
注意：我将域名替换为domain

应用返回URL（测试）：http://domain.esy.es/index.php/users/paypalidentity
查看

//url http://domain.esy.es/index.php
<span id="paypalButton"></span>
<script src="https://www.paypalobjects.com/js/external/api.js"></script>
<script>
    paypal.use( ["login"], function(login) {
        login.render ({
            "appid": MYAPPID,
            "authend": "sandbox",
            "scopes": "openid email profile address phone https://uri.paypal.com/services/paypalattributes",
            "containerid": "paypalButton",
            "locale": "en-us",
            "returnurl": "http://domain.esy.es/index.php/users/paypalidentity"
        });
    });
</script>
