java.lang.IllegalArgumentException: Invalid character found in the request target 异常

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 characters are defined in RFC 7230 and RFC
3986

一、在发送请求头参数给后端的时候会出现上述异常，这是由于tomcat配置引起，在SpringBoot项目中添加如下配置类即可。

/**

@Configuration
public class TomCatConfig {
    @Bean
    public TomcatServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers((Connector connector) -> {
            connector.setProperty("relaxedPathChars", "\"<>[\\]^`{|}");
            connector.setProperty("relaxedQueryChars", "\"<>[\\]^`{|}");
        });
        return factory;
    }
}

二、当请求头的参数过长时会出现 :

Note: further occurrences of HTTP request parsing errors will be
logged at DEBUG level.

java.lang.IllegalArgumentException: Request header is too larg

上述异常解决办法 : 修改application.properties或yaml配置文件添加 :

server.max-http-header-size=102400
