Apache Tomcat爆安全漏洞升级后报错误

最近Apache Tomcat 爆安全漏洞升级后报如下错误：

org.apache.coyote.http11.AbstractHttp11Processor process
信息: 解析 HTTP 请求 header 错误
Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: Invalid character found in the request target. The valid

前后端分离的 ，查相关解决办法catalina.properties里tomcat.util.http.parser.HttpParser.requestTargetAllow 增加相关缺失的特殊字符，官方不建议，经过修改与此也无关。接着通过测试接口get正常； post数据报错日志400错误；再查了一下接口位置post fsockopen 写法 \n  因此修改 \r\n 问题得到解决。
