Facebook oauth检索用户电子邮件 [英] Facebook oauth retrieve user Email

问题描述

  function login（）{ 
 FB.api（'/ me'，function（response）{
 alert（'你已成功登录，'+ response.name +'，+ response.email +！ 
 
}）; 
  

我检索所有基本信息（全名，工作，学校，ID ..），但不是EMAIL response.email == undefined）!!

我知道可以在基本信息中访问电子邮件（不要求电子邮件权限），我该怎么做？

解决方案

您需要通过以下方式获取电子邮件：

  var url ='/ me？fields = name，email'; 
 FB.api（url，function（response）{
 alert（response.name）; 
 alert（response.email）; 
}）; 
  

要获取电子邮件地址，需要电子邮件权限。所以代码可能看起来像（其他选项，如注册按钮，登录按钮..）

  FB.login（function回复）{
 if（response.session）{
 var url ='/ me？fields = name，email'; 
 FB.api（url，function（response）{
 alert（response.name）; 
 alert（response.email）; 
}）; 
} 
 else {
 alert（用户没有登录成功 ）; 
} 
}，{scope：'email'}）; / * perms更改为范围* / 
  

I am using Facebook Javascript SDK to get oauth token and retrieve all the data from FB:

 function login() {
    FB.api('/me', function (response) {            
        alert('You have successfully logged in, ' + response.name + ", " + response.email + "!");

    });

I retrieve all basic information (full name, work, school, ID..) but not EMAIL (response.email == undefined) !!

I know it's possible to access email within basic information (not asking for 'email' permissions), how do I do that?

解决方案

You need get email explicitly as follows:

                    var url = '/me?fields=name,email';
                    FB.api(url, function (response) {
                        alert(response.name);
                        alert(response.email);
                    });

And to get the email address, email permission is needed. So the code might look like (there are other options like Register button, login button..)

            FB.login(function (response) {
                if (response.session) {
                    var url = '/me?fields=name,email';
                    FB.api(url, function (response) {
                        alert(response.name);
                        alert(response.email);
                    });
                }
                else {
                    alert("User did not login successfully");
                }
            }, { scope: 'email' }); /* perms changed to scope */
