    "ErrCode": "1000",
    "ErrMsg": "执行成功",
    "Body": "{\"MobileInfos\":[{\"Name\":\"北京科技有限公司\",\"Address\":\"北京市朝阳区\",\"Phone\":\"01085555\",\"MobilePhone\":\"1371666666\",\"Email\":\"55558@QQ.com\",\"ContactName\":\"海天\",\"Position\":\"经理\",\"TimeStamp\":\"2015-11-12\"},{\"Name\":\"北京兴业机械有限公司\",\"Address\":\"北京市通州区\",\"Phone\":\"01057155555\",\"MobilePhone\":\"152555\",\"Email\":\"888837@qq.com\",\"ContactName\":\"王丰\",\"Position\":\"主管\",\"TimeStamp\":\"2015-11-14\"}}],\"Paging\":{\"PageIndex\":1,\"PageSize\":30,\"PageCount\":17080,\"TotalRecords\":512376}}"
