How to change charset in Apache Tomcat?

Question

Java

When trying to make a request ( localhost:8080/Users?s={"id": 27, "key": ["a1", "d3", "c5"]} ) Apache Tomcat throws an error: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986.

Answer 1

Apparently the problem is not in the charset, but in invalid characters in the URI. You need to encode the query string: https://docs.oracle.com/javase/8/docs/api/java/net...
