预览数据发现字段中有的有数据有的没数据

6 讨 论 395 浏览量 云采集引擎

数据源创建完成后,通过测试就可以开始云采集。

采集中有时会遇到一个字段有些数据没有信息,有些有信息。

造成这个情况的原因有两种情况:

1.规则配置问题

规则配置通过匹配抓取内容获取信息,如果页面有些小改动或者模板不同会造成规则无法再当前页面抓取正确信息

处理方法:单独页面调试,调整抓取规则

2.字符数超过字段限制

拓展字段对于字段长度存在一定限制,如果超过这个长度前面又刚好是空格的时候就会出现抓取空白信息

扩展字段对应存储空间

1-20:varchar(64),21-40:varchar(255),41-46:text(65535),47-48:mediumtext(16777215).

处理方法:确认抓取信息的长度,通过自定义脚本去除空格换行,如果抓取信息过长可以放在靠后的几个容量大的字段中

We spent a lot of time at her home. Maybe so her mother could keep an eye on us. Mrs. Spencer made sure to be around, offering drinks, snacks, chit chat. I noticed that she was fairly young herself. Granted at my age, anyone over 25 was old, but she was probably mid-30s, divorced. If she was a indiction of how Carley would develop, maybe I should wait. Mrs. Spencer had fuller breasts and a nice butt. She appeared to be in great shape for her "advanced" age. I knew she was keeping an eye on me as much as I was on her and her younger daughter. Her eldest, Sharon was away at college at the time. With Mrs. Spencer around we mostly limited ourselves to holding hands and sneaking in a few light kisses. One day Mrs. Spencer caught us by surprise walking in as I'd slid my hand up from Carley's stomach to rub her right breast through her shirt. She didn't really need a bra yet, so I could feel her nipple, hard, through her shirt. Just this much contact had me hard also.
