Could not verify the provided CSRF token because y

问题:

I am using spring security along with java config

@Override
protected void configure(HttpSecurity http) throws Exception { 
    http
    .authorizeRequests()
    .antMatchers("/api/*").hasRole("ADMIN")
    .and()
    .addFilterAfter(new CsrfTokenResponseHeaderBindingFilter(), CsrfFilter.class)
    .exceptionHandling()
    .authenticationEntryPoint(restAuthenticationEntryPoint)
    .and()
    .formLogin()
    .successHandler(authenticationSuccessHandler)
    .failureHandler(new SimpleUrlAuthenticationFailureHandler());

I am using PostMan for testing my REST services. I get 'csrf token' successfully and I am able to login by using X-CSRF-TOKEN in request header. But after login when i hit post request(I am including same token in request header that i used for login post request) I get the following error message:

HTTP Status 403 - Could not verify the provided CSRF token because your session was not found.

Can any one guide me what I am doing wrong.

According to spring.io:

When should you use CSRF protection? Our recommendation is to use CSRF protection for any request that could be processed by a browser by normal users. If you are only creating a service that is used by non-browser clients, you will likely want to disable CSRF protection.

So to disable it:

@Configuration
public class RestSecurityConfig extends WebSecurityConfigurerAdapter {
  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
  }
}

Note: CSRF protection is enabled by default with Java Configuration

try this: @Override protected boolean sameOriginDisabled() { return true;}

@Configuration
public class WebSocketSecurityConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {

    ...

    // Determines if a CSRF token is required for connecting. This protects against remote
    // sites from connecting to the application and being able to read/write data over the
    // connection. The default is false (the token is required).
    @Override
    protected boolean sameOriginDisabled() {
        return true;
    }
}

Disabling CSRF protection is a bad idea.

Spring will automatically generate a new CSRF token after each request, and you need to include it in all HTTP requests with side-effects (PUT, POST, PATCH, DELETE).

In Postman you can use a test in each request to store the CSRF token in a global, e.g. when using CookieCsrfTokenRepository

pm.globals.set("xsrf-token", postman.getResponseCookie("XSRF-TOKEN").value);

And then include it as a header with key X-XSRF-TOKEN and value {{xsrf-token}}.

I have solved it by adding the last attribute in my login page,maybe it will do yo a favor.

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"  isELIgnored="false"%>
