Test my Spring Boot endpoints with curl

I'm learning Spring Boot and I want to test my endpoints using curl, but I have a problem: I can't because returns me 401 code, possibly I need a basic authentication (curl username and password). How can set it up in curl and in my Spring Boot project?

do you already have authentication set up in spring or you dont have any at all

Franscis123$#OP•6mo ago

No. I don't have any authentication.

ayylmao123xdd•6mo ago

also a better option would be to use postman btw looks way better anyway is your application on your local machine show the endpoint and the response

Franscis123$#OP•6mo ago

Yeah, is in local.

ayylmao123xdd•6mo ago

do you have spring security added i dont mean any code just the dependency

Franscis123$#OP•6mo ago

Yeah

ayylmao123xdd•6mo ago

if you remove the dependency its gonna work but if you want to keep the dependency you need to setup the endpoints sooooo if you choose the latter make a class named SecurityConfig and paste this

@Configuration
@EnableWebSecurity
public class SecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
    @Bean
    public BCryptPasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
                .authorizeHttpRequests(auth -> auth
                        .anyRequest().permitAll())
                .httpBasic(Customizer.withDefaults())
                .csrf(AbstractHttpConfigurer::disable);
        return http.build();
    }

    @Bean
    public AuthenticationManager authenticationManager(AuthenticationConfiguration configuration) throws Exception {
        return configuration.getAuthenticationManager();
    }
    
}

@Configuration
@EnableWebSecurity
public class SecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
    @Bean
    public BCryptPasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
                .authorizeHttpRequests(auth -> auth
                        .anyRequest().permitAll())
                .httpBasic(Customizer.withDefaults())
                .csrf(AbstractHttpConfigurer::disable);
        return http.build();
    }

    @Bean
    public AuthenticationManager authenticationManager(AuthenticationConfiguration configuration) throws Exception {
        return configuration.getAuthenticationManager();
    }
    
}

and then when you launch the application it will work that might or might not work depending on your spring security version but for the new ones will work

Franscis123$#OP•6mo ago

Thanks! Now it works and create the register in the DB as expected
