当我在 URI 中使用“\”作为路径定界符时，我在 tomcat 8.5.15 中收到非法参数异常。以下是错误消息:-
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.
java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

为了绕过这个问题我尝试添加
org.apache.catalina.connector. CoyoteAdapter.ALLOW_BACKSLASH=true
在 catalina.properties 中，我仍然无法解决问题。
最佳答案
要解决此问题，您可以设置 requestTargetAllow 选项。只需取消注释文件中的最后一行即可。
$CATALINA_HOME/conf/catalina.properties
关于Tomcat.8.5.15 不接受 URI 中的 "\"并抛出 IllegalArgumentException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45933343/
