Spring Security DefaultHttpFirewall-requestURI不能包含编码的斜杠 [英] Spring security DefaultHttpFirewall - The requestURI cannot contain encoded slash

问题描述

在启用了安全性的网络应用程序的春季启动中，执行包含编码的斜杠的GET请求时出现以下错误

In a spring-boot with security enabled web app, I'm getting the following error when performing a GET request which contains an encoded slash

http://172.16.62.11:8080/customers/emails/BceGjcCovvKn5VM5eEeoG％2FgIr9bh1FpiC0Ofl3umGqU％3D/foo

org.springframework.security.web.firewall.RequestRejectedException: The requestURI cannot contain encoded slash. Got /customers/emails/BceGjcCovvKn5VM5eEeoG%2FgIr9bh1FpiC0Ofl3umGqU%3D/foo

设置System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH", "true")没有帮助.

推荐答案

发现了问题-显然，在最新版本的spring security中，URL中编码斜杠的使用已被阻止

Found out the issue - apparently in latest release of spring security, the usage of encoded slashes in url has been blocked

https://github.com/spring-projects/spring-security/commit/666e356ebc479194ba51e43bb99fc42f849b6175

要解决此问题，请按如下所示向WebSecurity提供您自己的HttpFirewall实现

To overcome this, provide your own HttpFirewall implementation to WebSecurity as follows

@Bean
public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
    DefaultHttpFirewall firewall = new DefaultHttpFirewall();
    firewall.setAllowUrlEncodedSlash(true);
    return firewall;
}

@Override
public void configure(WebSecurity web) throws Exception {
    web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
}
