javascript - 是否仍然可以获得 Facebook 好友电子邮件列表？

Question

您好，请帮助我运行下面的代码来获取用户的详细信息，例如姓名和电子邮件，但是否也可以获取他们的 FB friend 的电子邮件？也许改变这个

FB.api('/me', {fields: 'name,email'}*

进入这个

FB.api('/me/friends', {fields: 'name,email'} ?

并在控制台中将其显示为这样的数组？

[{email: 'someone0@email.com'},
{email: 'someone1@email.com'},
{email: 'someone2@email.com'},
{email: 'someone3@email.com'}]

您可以从这里测试示例页面:https://domain/referral

<script>
      window.fbAsyncInit = function() {
        FB.init({
          appId      : 'xxxxxxxxxxxxxxxxxx', // Set YOUR APP ID
          // channelUrl : 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx', // Channel File
          status     : true, // check login status
          cookie     : true, // enable cookies to allow the server to access the session
          xfbml      : true  // parse XFBML
        });
    
        FB.Event.subscribe('auth.authResponseChange', function(response) 
        {
         if (response.status === 'connected')

你检查了吗？ https://developers.facebook.com/docs/graph-api/reference/user/

如果我在 https://developers.facebook.com/tools/explorer/ 中做你做的事

Facebook 给出的响应

Query

curl -i -X GET "https://graph.facebook.com/v2.10/me/friends?access_token=<accesstoken sanitized>"

Response

{
"data": [],
"summary": {
"total_count": 8
},
"__debug__": {
"messages": [
{
"link": "https://developers.facebook.com/docs/apps/changelog#v2_0",
"message": "Only friends who installed this app are returned in API v2.0 and higher. total_count in summary represents the total
number of friends, including those who haven't installed the app.",
"type": "info"
}
]
} }


Debug Information from Graph API Explorer

• https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=me%2Ffriends&version=v2.10

有没有看到

Only friends who installed this app are returned in API v2.0 and higher. > total_count in summary represents the total number of friends, including those who haven't installed the app

所以你不能像这样交 friend 。就像 @CBroe 说的那样

A user’s email is only accessible after they personally grant your app permission.
