数据格式如下
{"data":[{"result":{"total":2002,"fields":["null","searchword","ip","visit_pages"],"items":[{"detail":{"deviceType":"mobile","os":"Android","cookie":"支持","color":"32-bit","visitorType":"新访客","isp":"","language":"","resolution":"","userId":"28074059","browserType":"other","ipStatus":"","visitorFrequency":"1","java":"不支持","lastVisitTime":"首次访问","fromType":{"fromType":"搜索推广(关键词:xx 搜索词:阿xx用)","fromAccount":"xx","url":"xx"},"antiCode":"A284C556C2AA2A51","paths":"16:06:46","未知","xx","browser":"手机百度","osType":"android","visitorStatus":"","endPage":"xx","flash":"","accessPage":"xx"}},"xx","140.243.41.10","1"]}}]}

获取items jsonArray为null
