Question

这会通过accounts-password为您登录用户的电子邮件地址。

Meteor.user().emails[0].address

当用户使用第三方服务登录时，如何在客户端/服务器上获取电子邮件地址？例如。 facebook，谷歌。

我想从客户端调用以下方法

Meteor.methods({
    sendEmail: function() {
        var userEmail;
        if(Meteor.user().emails[0].address) {
            return userEmail = Meteor.user().emails[0].address;
        } else if (Meteor.user().services.google.email) {
            return userEmail = Meteor.user().services.google.email;
        } else if (Meteor.user().services.facebook.email) {
            return userEmail = Meteor.user().services.facebook.email;
        }
        Email.send({
            to: userEmail,
            from: "example@gmail.com",
            subject: "some subject",
            text: "sometext"
        });
    }
});

我得到TypeError: Cannot read property '0' of undefined

我不喜欢这样，但它的工作原理

Meteor.methods({
    sendEmail: function() {
        this.unblock();
        var currentUser = Meteor.user();
        if (currentUser && currentUser.emails && currentUser.emails[0] 
            && currentUser.emails[0].address) {
            var userEmail = currentUser.emails[0].address;
            Email.send({
                to: userEmail,
                from: "something@gmail.com",
                subject: "something",
                text: "something"
            });
        } else if (currentUser && currentUser.services && currentUser.services.google 
            && currentUser.services.google.email) {
            var userEmail = currentUser.services.google.email;
            Email.send({
                to: userEmail,
                from: "something@gmail.com",
                subject: "something",
                text: "something"
            });
        } else if (currentUser && currentUser.services && currentUser.services.facebook 
            && currentUser.services.facebook.email) {
            var userEmail = currentUser.services.facebook.email;
            Email.send({
                to: userEmail,
                from: "something@gmail.com",
                subject: "something",
                text: "something"
            });
        }
    }
});

我认为它只是假设它可以发送一封电子邮件到空字符串/ null / undefined。我试图在if(!userEmail)上抛出Meteor.Error没有运气。如果有人可以使这个代码更整洁，我会很感激。

如何通过客户端或服务器上的第三方服务登录用户的电子邮件地址？
