如何使用 jQuery 从 Google 读取联系人信息？

Question

我正在使用 Google 的 API 来获取我的联系人列表的信息，并在使用控制台日志后获取信息

    function fetch(token) {
    $.ajax({
      url: "https://www.google.com/m8/feeds/contacts/default/full?access_token=" + token.access_token + "&alt=json",
      dataType: "JSON",
      success:function(data) {

        var json = JSON.stringify(data);

        console.log(json);
      }
    });
  }

我正在获取此信息

我想读取 "address" 的值来获取电子邮件地址，但我不知道如何，我尝试使用 $.each 但每次的值都是 "undefined"，我应该怎么做才能收到电子邮件？

Answer 1

你到底想在什么上调用 $.each？在整个 data 对象上，或某些属性?

如果您只想获取电子邮件地址列表，可以使用 map 函数遍历 data.feed.entry 数组并提取嵌套的 gd$email[0].address 值，如下所示:

var emailAddresses = data.feed.entry.map(function(entry) {
    //take the first gd$email item the entry has
    var gdEmail = entry['gd$email'][0];
    //this assumes all entries will have a gd$email, 
    //  you may want to implement a null check
    return gdEmail.address;
});
