How can I get the jsessionid from a response using react js?

Question

Context

• Spring Boot
• React Js

Issue

I want to make a login request from react to get the jsessionid . I am getting a weird response from Spring Boot . In the response i don't find any cookies. In postman i can just give the username and password in the url as parameters and in the response I am getting a response with the cookie jsessionid and for more requests I can just use it. But in react I am getting a weird response and I don't know how to get the cookie.

Here is the code that sends the request from React JS to Spring Boot :

const { username, password } = this.state;
    const student = { username, password };
    fetch("http://localhost:8080/login", {
      method: "POST",
      body: new URLSearchParams(student)
    })
      .then(res => {
        console.log(res);
        const jsessionid = document.cookie;
        console.log("id", jsessionid);
        //Here I am trying to get the jsessionid
      })
      .catch(error => console.log(error));

This is the response that I am getting and that I printed out in the console

And here is my Spring Securtiy Configuration Class :

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Autowired
    UserDetailsServiceImpl userDetailsService;

    @Bean
    DaoAuthenticationProvider authenticationProvider(){
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        daoAuthenticationProvider.setUserDetailsService(userDetailsService);
        return daoAuthenticationProvider;
    }



    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable().cors().and()
                .authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .formLogin();
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider());
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("*"));
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }



}

Here I tried with curl and as you can see I am getting the cookie jsessionid .

Answer 1

You can access your jsessionid from response.header
for example

fetch("http://localhost:8080/login", {
  method: "POST",
  body: new URLSearchParams(student)
  credentials: 'include', 
  headers: {
  'Content-Type': 'application/json'
  } 
  })
  .then(res=>console.log(res.headers.get('set-cookie'));)

  .catch(error => console.log(error));
