从php中的谷歌联系人检索群组联系人

Question

我已经按照https://developers.google.com/google-apps/contacts/v3/#retrieving_a_single_contact_group的说明进行了群组数据。

但每当我尝试使用https://www.google.com/m8/feeds/groups/default/full获取分组智能数据时，我只获得给定数组中的组ID，而不是其他数据（如名称，手机号码）。

下面给出了一个给定的数组，以便更好地理解

[0] => Array
(
    [gd$etag] => "YDwreyM."
    [id] => Array
        (
            [$t] => http://www.google.com/m8/feeds/groups/rahmanarafat13%40gmail.com/base/6
        )

    [updated] => Array
        (
            [$t] => 1970-01-01T00:00:00.000Z
        )

    [category] => Array
        (
            [0] => Array
                (
                    [scheme] => http://schemas.google.com/g/2005#kind
                    [term] => http://schemas.google.com/contact/2008#group
                )

        )

    [title] => Array
        (
            [$t] => System Group: My Contacts
        )

    [content] => Array
        (
            [$t] => System Group: My Contacts
        )

    [link] => Array
        (
            [0] => Array
                (
                    [rel] => self
                    [type] => application/atom+xml
                    [href] => https://www.google.com/m8/feeds/groups/rahmanarafat13%40gmail.com/full/6?v=3.0
                )

        )

    [gContact$systemGroup] => Array
        (
            [id] => Contacts
        )

)

请勿获取['gd $ name']或['gd $ phoneNumbe']等其他值。

我现在该怎么办？
