How to add csrf token to the html form?

Question

After I enabled csrf(removed line .csrf().disable()) in my application my login request stopped working - /login POST redirects me to the home page:

request looks like this:

On the page I have following js:

<script type="text/javascript" src="/webjars/js-cookie/js.cookie.js"></script>
...
$('#login-form').submit(function (ev) {
    ev.preventDefault(); // to stop the form from submitting
    var headerName = "X-CSRF-TOKEN";
    var token = Cookies.get('XSRF-TOKEN')
    $('<input>').attr('type', 'hidden').attr('name', '_csrf').attr('value', Cookies.get('XSRF-TOKEN')).appendTo('#login-form');
    this.submit(); // If all the validations succeeded
    })

Can you clarify what am doing wrong?

P.S.

I read a lot of related stuff and everywhere I found lines like this:

<meta name="_csrf" content="${_csrf.token}"/>
<!-- default header name is X-CSRF-TOKEN -->
<meta name="_csrf_header" content="${_csrf.headerName}"/>

I don't understand how should I set value _csrf.headerName

I tried to add these data to meta bit its doesn't resolve:

and I tried to add it to the form directly:

And no success again.

Additionally i tried this:

But as you can see - it doesn't resolve my attributes too

P.S.2

configuration:

EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private static final String SECURE_ADMIN_PASSWORD = "rockandroll";

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .formLogin()
                .loginPage("/index.html")
                    .loginProcessingUrl("/login")
                    .defaultSuccessUrl("/sender.html")
                    .permitAll()
                .and()
                .logout()
                    .logoutSuccessUrl("/index.html")
                    .permitAll()
                .and()
                .authorizeRequests()
                .antMatchers("/js/**", "/lib/**", "/images/**", "/css/**", "/index.html", "/","/*.css","/webjars/**", "/*.js").permitAll()
                .antMatchers("/websocket").hasRole("ADMIN")
                .requestMatchers(EndpointRequest.toAnyEndpoint()).hasRole("ADMIN")
                .anyRequest().authenticated();

    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

        auth.authenticationProvider(new AuthenticationProvider() {

            @Override
            public boolean supports(Class<?> authentication) {
                return UsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication);
            }

            @Override
            public Authentication authenticate(Authentication authentication) throws AuthenticationException {
                UsernamePasswordAuthenticationToken token = (UsernamePasswordAuthenticationToken) authentication;

                List<GrantedAuthority> authorities = SECURE_ADMIN_PASSWORD.equals(token.getCredentials()) ?
                        AuthorityUtils.createAuthorityList("ROLE_ADMIN") : null;

                return new UsernamePasswordAuthenticationToken(token.getName(), token.getCredentials(), authorities);
            }
        });
    }
}

build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.1.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

jar {
    baseName = 'gs-messaging-stomp-websocket'
    version = '0.1.0'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-websocket")
    compile("org.webjars:webjars-locator-core")
    compile("org.webjars:sockjs-client:1.0.2")
    compile("org.webjars:stomp-websocket:2.3.3")
    compile("org.webjars:bootstrap:3.3.7")
    compile("org.webjars:jquery:3.1.0")
    compile("org.webjars:js-cookie:2.1.0")

    compile("org.springframework.boot:spring-boot-starter-actuator")
    //security
    compile ('org.springframework.security:spring-security-messaging')
    compile group: 'org.springframework.security', name: 'spring-security-web'
    compile group: 'org.springframework.security', name: 'spring-security-config'

    testCompile("org.springframework.boot:spring-boot-starter-test")
}

Solution

I tried different ways and eventually I've found the solution:

Previously index.html was located in the folder /resources/static

I put it in the folder /resources/templates. Also I've added dependency:

compile('org.thymeleaf:thymeleaf-spring5');

and explicitly declared the controller:

@RequestMapping("/")
public String index(){
   return "index";
} 

index.html look like this:

<html lang="en" ng-app="springChat" xmlns:th="http://www.springframework.org/schema/beans">
<head>
    ...
    <meta name="_csrf" th:content="${_csrf.token}"/>
    <meta name="_csrf_parameter_name" th:content="${_csrf.parameterName}"/>

....
</body>     
<script type="application/javascript">

    $('#login-form').submit(function (ev) {
        ev.preventDefault(); // to stop the form from submitting
        var token = $("meta[name='_csrf']").attr("content");
        var paramName = $("meta[name='_csrf_parameter_name']").attr("content");
        $('<input>').attr('type', 'hidden').attr('name', paramName).attr('value', token).appendTo('#login-form');

        this.submit(); 
    });
</script>
</html>

Looks like spring boot searches in /resources/static raw html if we don't have explicitly declared mapping and doesn't try to insert values like th:content="${_csrf.token}" into variables.

Ok, I can see U added more info. I'd like to ask you to add more details about what error you are getting (or what behavior you expect but it does not work that way).

[holmis83]

Do you use server template language JSP or Thymeleaf?

[gstackoverflow]

@holmis83 I use raw html

[gstackoverflow]

@john Result the same). /login responds 302 instead of successful login. Login happens successfuly in case of I disable csrf explicitly(.csrf().disable())

[gstackoverflow]

I use raw html so I can't use it

[venkatReddi]

This solution works, but do you know why in a jsp form we can send that a form data, but when we are doing Ajax we need to add it as a header instead of form data in body? Confusing

thanks! just to get attention th: is very important prefix here.
