爬虫,MySQL,定时任务
在进行到将数据存到数据库中的时候 ,即在应用根目录下执行 node update/all.js后,控制台出现了Error: ER_TRUNCATED_WRONG_VALUE_FOR_FIELD: Incorrect string value: '\xE4\xBF\xA1\xE5\x85\xAC...' for column 'content' at row 1
这个要怎么解决呢

你好,参照NODE.JS实战中的第六章,试着实现网络爬虫,但是,在启动服务后,并未获得到抓取的文章列表,望解答。
1.在工程目录下 node app.js
2.打开浏览器 localhost:3900,显示【我的博客首页】,但下方未显示出文章列表,不知道问题出在哪里,请不吝赐教。
BEST REGARDS!
您好,因为我参加学校的一个小项目,然后需要一些数据,看到您的爬虫教程。但是有些其他细节问题想问您。
1.如果我想做一个需要登录验证才能获取的数据html页面(从教务处内获取课程表),请问怎么爬取呢?(如果不登录,是否能爬去所有学生的课程表)
2.需要爬去一个公众号的历史消息记录,还有详情,但是我网页打开历史记录提示(请在微信客户端打开链接。)该如何避免这个提示,获取所有历史记录。
