tomcat通过url传参报错：The valid characters are defined in RFC 7230 and RFC3986

解决：Invalid character found in the request target.The valid characters are defined in RFC 7230 and RFC3986

处理方法

.../conf/catalina.properties中，找到最后注释掉的一行 ＃tomcat.util.http.parser.HttpParser.requestTargetAllow=| 　，改成tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}，表示把｛｝放行
