是否仍然可以获得Facebook好友的电子邮件列表？

Question

嗨，请帮助我运行下面的代码来获取用户的详细信息，如姓名和电子邮件，但是也可以让他们的FB朋友发送电子邮件？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: '[email protected]'},
{email: '[email protected]'},
{email: '[email protected]'},
{email: '[email protected]'}]

你检查过这个吗？ https://developers.facebook.com/docs/graph-api/reference/user/

如果我做你在https://developers.facebook.com/tools/explorer/做的事情

响应facebook给出了

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

你有没有看到

只有安装此应用程序的朋友才能在API v2.0及更高版本中返回。 > total_count in summary表示朋友的总数，包括尚未安装该应用的朋友

所以你不能得到这样的朋友。就像@CBroe说的那​​样

用户的电子邮件只有在他们个人授予您的应用程序权限后才能访问。
