关于高版本tomcat对于前端输入的url header抛出异常的问题
Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986该问题经查询是高版本tomcat对于http头部的规范的限制，不知道论坛有没有人能解答一下如果要从代码上来解决应该怎么做。按我的理解是需要对头部进行encode处理，但是刚入门还不清楚整个代码在哪一部分是统一处理这一块的。
报错如下：
org.apache.coyote.http11.Http11Processor.service Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
