解决Invalid character found in the request问题

Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

原因

SpringBoot 2.0.0 以上都采用内置tomcat8.0以上版本，而tomcat8.0以上版本遵从RFC规范添加了对Url的特殊字符的限制，url中只允许包含英文字母(a-zA-Z)、数字(0-9)、-_.~四个特殊字符以及保留字符( ! * ’ ( ) ; : @ & = + $ , / ? # [ ] ) (262+10+4+18=84)这84个字符,请求中出现了{}大括号或者[],所以tomcat报错。

设置RelaxedQueryChars允许此字符(建议)，设置requestTargetAllows选项(Tomcat 8.5中不推荐)。

根据Tomcat文档，下面提供一种方法来设置松弛的QueryChars属性*

在启动类中添加

    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                connector.setProperty("relaxedQueryChars", "|{}[]");
            }
        });
        return factory;
    }

springboot项目报错问题

Java.lang.IllegalArgumentException:Invalid character found in the request target.

原因

java.lang.IllegalArgument编程Exception: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

高版本tomcat中的新特性：就是严格按照 RFC 3986规范进行访问解析，而 RFC 3986规范定义了Url中只允许包含英文字母（a-zA-Z）、数字（0-9）、-_.~4个特殊字符以及所有保留字符(RFC3986中指定了以下字符为保留字符：! * ’ ( ) ; : @ & = + $ , / ? # [ ])。

springboot默认集成了tomcat，tomcat然后当你前端发送请求，请求参数中有保留的特殊字符时，就会报如下错

有两种解决方法

在config中新建一个TomcatConfig类

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

然后重启项目测试，问题解决

以上为个人经验，希望能给大家一个参考，也希望大家多多支持我们。
