无法通过Facebook API获取用户电子邮件(Not able to fetch user email via facebook api)

无法通过Facebook API获取用户电子邮件(Not able to fetch user email via facebook api)

我在下面使用：

window.fbAsyncInit = function() { FB.init({ appId : 'my-app-id', xfbml : true, version : 'v2.7' }); }; (function(d, s, id){ var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) {return;} js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/sdk.js"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));

并试图获取电子邮件信息如下：

FB.api('/me?fields=name,email', function (response) { console.log(response.name + ' --- '+response.email); });

输出是：Nitesh Kumar ---未定义

How to get email of user?

最满意答案

您需要在登录过程中询问电子邮件权限：

FB.login(function(response) { if (response.authResponse) { //user just authorized your app } }, {scope: 'email'});

顺便说一句，这是正确的（包括最先进的ES6箭头功能）：

FB.api('/me', {fields: 'name,email'}, (response) => { console.log(response.name + ' --- ' + response.email); });

You need to ask for the email permission in the login process:

FB.login(function(response) { if (response.authResponse) { //user just authorized your app } }, {scope: 'email'});

Btw, this would be correct (including state oft the art ES6 arrow functions too):

FB.api('/me', {fields: 'name,email'}, (response) => { console.log(response.name + ' --- ' + response.email); });
