Error parsing HTTP request header

描述

当在浏览器中访问时,URL中带有特殊字符，如花括号冒号时，就会出现这个错误

Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

修改catalina.properties中代码，如下：

tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}
