现在有如下字段：
{
"errcode": 0,
"errmsg": "ok",
"card": {
"card_id": "p0eK60jD5OeGfhLbUC22222rsjR9toAx4",
"begin_time": 0,
"end_time": 4294967222295,
"bonus": 120,
"code": "223424393077",
"membership_number": "223424393077"
},
"openid": "o0eK60hF4tI2222uXFF2OMCTCNn50iYs",
"can_consume": true,
"user_card_status": "NORMAL",
"outer_str": "Floph5_1217",
"background_pic_url": "xxxxxx",
"unionid": "xxxx"
}

目前只返回了
{
"errcode": 0,
"errmsg": "ok",
"card": {
"card_id": "p0eK60jD5OeGfhLbUC22222rsjR9toAx4",
"begin_time": 0,
"end_time": 4294967222295,
"bonus": 120
},
"openid": "o0eK60hF4tI2222uXFF2OMCTCNn50iYs",
"can_consume": true,
"user_card_status": "NORMAL"
}
