为了解决Error parsing HTTP request header
 Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level.这个问题,

 

网上查了查需要修改一下tomcat中的配置,因为我用的是Spring boot 集成的tomcat所以只在配置中修改一下就行了 

我的项目环境是liunx+Springboot集成tomcat+https认证

发现maxHttpHeaderSize这个属性使用

server.tomcat.max-http-header-size显示为失效

后来查了一下去掉tomcat就好了,记录一下

server.max-http-header-size=10240

细心的同学通过这个点进去就会发现默认值是8*1024.这里我改成了10240(10*1024)

目前来看经过一步步修改这个数值,这类错误日志是明显减少了,但是还是有.

4.15更新:server.max-http-header-size=15360  现在没有了

5.21更新:这段时间在忙,一直没有关注,查看日志现在差不多每天一次报这个错误

8.3更新:在一个帖子说可能请求参数总包含啦 | 特殊字符,考虑线上有爬虫等等,我先把url请求日志打出来,过段时间更新,给大家提供一个思路试试
