为什么我用https://api.weixin.qq.com/cgi-bin/user/info?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN这个接口来获取用的基本信息

有的用户返回全字段

{
    "subscribe": 1, 
    "openid": "o6_bmjrPTlm6_2sgVt7hMZOPfL2M", 
    "nickname": "Band", 
    "sex": 1, 
    "language": "zh_CN", 
    "city": "广州", 
    "province": "广东", 
    "country": "中国", 
    "headimgurl":"http://thirdwx.qlogo.cn/mmopen/g3MonUZtNHkdmzicIlibx6iaFqAc56vxLSUfpb6n5WKSYVY0ChQKkiaJSgQ1dZuTOgvLLrhJbERQQ4eMsv84eavHiaiceqxibJxCfHe/0",
    "subscribe_time": 1382694957,
    "unionid": " o6_bmasdasdsad6_2sgVt7hMZOPfL"
    "remark": "",
    "groupid": 0,
    "tagid_list":[128,2],
    "subscribe_scene": "ADD_SCENE_QR_CODE",
    "qr_scene": 98765,
    "qr_scene_str": ""
}

有的用户直返回3个字段

{
    "subscribe": 1, 
    "openid": "o6_bmjrPTlm6_2sgVt7hMZOPfL2M", 
    "tagid_list":[],
}
