403 Error when sending post request to external API

403 Error when sending post request to external API - java

I have an Angular App that is used to compile a java program, I am using Jdoodle API for compilation, we send requests to Jdoodle and then get a response back, and that response is displayed over the UI. In Postman everything works fine but in the Spring boot app this gives me a 403 error.

Any help would be highly appreciated. Thanks in Advance.
Full Code over Github: https://github.com/vishwaratna/Synpulse_Online_portal

This is what I understand you are sending wrong data to the API.
OutputStream outputStream = connection.getOutputStream();
outputStream.write(input.getBytes());
You are sending input object as request.
But you should send the actual input which has script and language.
So you should write the actual object with script/code, in your case it is c
So please try to replace code with:
convert the object c into json string and then pass json string.
OutputStream outputStream = connection.getOutputStream();
outputStream.write(jsonStringOfC.getBytes());
Also if you can share API documentation, It will be easy to help.

I checked out the jdoodle API, and even though it is not clear, I would say you have issues with your credentials. Perhaps a typo or you used up your credits. Can you please post the response of https://api.jdoodle.com/v1/credit-spent using your clientId and clientSecret?

I don't know much about java (more in node.js) but 403 is a forbidden message which means that you might have not given the proper authorization

Instead of sending the post to the API, log it, then post it into a JSON validator such as https://jsonlint.com/. You're not sending valid JSON, and you're getting a 403 access denied because of it.

If you didn’t add user agent in header you may get this 403 error.
headers.add(“user-agent”, “Application”);

IllegalStateException after trying to access a specific URL with AbstractPreAuthenticatedProcessingFilter implementation

We have extended AbstractPreAuthenticatedProcessingFilter to authenticate shibboleth users, it does nothing special but obtain the user name from a specific request attribute and return a PreAuthenticatedAuthenticationToken.
If we access the root context of our application it works ok, but if we request a specific URL within our application we get "java.lang.IllegalStateException: Response already commited".
In SecurityConfig we have:
#Override
protected void configure(final HttpSecurity http) throws SecurityException {
try {
http.authorizeRequests().antMatchers("/favicon.ico", "/resources/**", "/signin**").permitAll()
.anyRequest().authenticated().and().formLogin().loginPage("/signin").permitAll()
.failureUrl("/signin?error=1").successHandler(new CustomAuthenticationSuccessHandler())
.loginProcessingUrl("/authenticate").and().sessionManagement().invalidSessionUrl("/signin")
.and().exceptionHandling().accessDeniedHandler(new AccessDeniedHandler()).and().headers()
.frameOptions().disable();
http.addFilterBefore(
new ShibbolethPreAuthenticatedProcessingFilter(new ShibbolethAuthenticationManager(),
new CustomAuthenticationSuccessHandler()),
AbstractPreAuthenticatedProcessingFilter.class);
http.logout().logoutUrl("/logout")
.logoutSuccessUrl(environment.getProperty(Constantes.CT_SHIBBOLETH_LOGOUT_URL))
.clearAuthentication(true).invalidateHttpSession(true);
} catch (final Exception e) {
throw new SecurityException(e);
}
}
ShibbolethAuthenticationManager implements AuthenticationManager and just loads UserDetails and GrantedAuthorities into a PreAuthenticatedAuthenticationToken
CustomAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler and loads the user language into the LocaleProvider and loads the current license details into the session.
If we request for "/" in our application it takes us to:
#ResponseStatus(HttpStatus.MOVED_PERMANENTLY)
#RequestMapping("/")
public String index(HttpServletRequest httpRequest, HttpSession session, Authentication auth) {
if (auth.getAuthorities().contains(new SimpleGrantedAuthority(Constants.CONTROL_PANEL_PERMISSION))) {
return "redirect:/controlpanel/dashboard";
} else if (auth.getAuthorities().contains(new SimpleGrantedAuthority(Constants.CONFIG_PERMISSION)))
{
return "redirect:/config";
} else {
return "redirect:/userpage";
}
}
I don't know why those redirects work, but not when we request another URL, for example if we request to go directly to /controlpanel/dashboard we get the error.
#RequestMapping("/controlpanel/dashboard")
public String dashboard(Model model, HttpServletRequest httpRequest, HttpSession session,
#RequestParam(name = "comite", defaultValue = "-1") Long comite,
#RequestParam(required = false) final Boolean tasksToDo) {
// This method does nothing but add things to the model object, such as:
model.addAttribute("tasks", tasksToDo);
// and then it takes the user to the view page
return "cuadromando/dashboard";
}

In the end I solved it by implementing AuthenticationSuccessHandler instead of extending SavedRequestAwareAuthenticationSuccessHandler:
CustomSuccessHandler implements AuthenticationSuccessHandler
So I get rid of the commited response, because both SavedRequestAwareAuthenticationSuccessHandler and SimpleUrlAuthenticationSuccessHandler called getRedirectStrategy().sendRedirect(request, response, targetUrl); so they commited the response before we could do the actual redirect we needed.

Spring boot with spring session and security. RMI fails with 401

I'm using Spring boot with spring security and Spring Session with redis for authentication and authorization. There are two separate projects running and I want to connect them with RMI tunneled over HTTP.
Even though I've used setRemoteInvocationFactory in HttpInvokerProxyFactoryBean Since the 2nd service throws 401. I'm getting Internal server error. What's the workaround?
I'm passing session id in the header as x-auth-token. Should I pass the same through service invoker?
Here is the code
Exporter:
#Configuration
#EnableAutoConfiguration
public class ServiceExporter {
#Bean(name = "/rmi")
HttpInvokerServiceExporter accountService(#Autowired rmiimpl rmi) {
HttpInvokerServiceExporter exporter = new HttpInvokerServiceExporter();
exporter.setServiceInterface(rmiinterface.class);
exporter.setService(rmi);
return exporter;
}
}
Invoker:
#Configuration
#EnableAutoConfiguration
public class test {
#Bean
public HttpInvokerProxyFactoryBean invoker() {
HttpInvokerProxyFactoryBean invoker = new HttpInvokerProxyFactoryBean();
String serviceURL = "http://localhost:8081/rmi";
invoker.setServiceUrl(serviceURL);
invoker.setServiceInterface(rmiinterface.class);
invoker.setRemoteInvocationFactory(remoteinvocation());
return invoker;
}
#Bean
RemoteInvocationFactory remoteinvocation() {
return new ContextPropagatingRemoteInvocationFactory();
}
}
SecurityConfig:
#Configuration
#EnableWebSecurity
public class SessionSecurityConfig extends WebSecurityConfigurerAdapter {
#Bean
public HttpSessionStrategy httpSessionStrategy() {
return new HeaderHttpSessionStrategy();
}
#Override
protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("admin").password("adminPass").roles("ADMIN");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
// https://www.baeldung.com/spring-security-session
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED);
http.csrf().disable().authorizeRequests() //
.antMatchers("/auth/*").fullyAuthenticated() //
.and().requestCache() //
.requestCache(new NullRequestCache()) //
.and().httpBasic();
}
}
Exception:
java.io.IOException: Did not receive successful HTTP response: status code = 401, status message = [null]

Not sure what's missing.

Finally Figured out.
AS we all know that Spring Security reads Session Id from cookie by default. In this case, since I've used #Bean public HttpSessionStrategy it reads from header x-auth-token.
Whenever HttpInvokerProxyFactoryBean tries to connect the authentication context is propagated but since it's an HTTP call the default spring session filter tries reading the session ID and validate the same. Since here session Id is not transmitted it throws 401.
In order to fix it. I need to set the header in HTTP invoker. The same applies if cookie is used. Since HttpInvokerProxyFactoryBean uses SimpleHttpInvokerRequestExecutor. I created a new class by extending it and added the header by overriding prepareConnection. I used setHttpInvokerRequestExecutor in invoker to set the executor to call the new class.
Here is the code.
Invoker:
#Configuration
#EnableAutoConfiguration
public class test {
#Bean
public HttpInvokerProxyFactoryBean invoker() {
HttpInvokerProxyFactoryBean invoker = new HttpInvokerProxyFactoryBean();
String serviceURL = "http://localhost:8081/rmi";
invoker.setServiceUrl(serviceURL);
invoker.setServiceInterface(rmiinterface.class);
invoker.setHttpInvokerRequestExecutor(httpInvokerRequestExecutor()); //call to the bean
return invoker;
}
#Bean
public SimpleHttpInvokerRequestExecutor httpInvokerRequestExecutor() {
return new CustomHttpInvokerRequestExecutor();
}
}
class CustomHttpInvokerRequestExecutor extends SimpleHttpInvokerRequestExecutor {
#Autowired
HttpSession session;
#Override
protected void prepareConnection(HttpURLConnection connection, int contentLength) throws IOException {
// adding header.
connection.addRequestProperty("x-auth-token", session.getId());
super.prepareConnection(connection, contentLength);
}
}
Now it started working.

Return null point exception inside in Repositories - Spring Boot

I am beginner in Spring boot programming. But I am still creating a software application which is based on shopping cart web, being developed with Spring boot. But suddenly, I got an error again and again which returns null and null point exception inside in save function(Repository).
I don't know why. I have tried several times to execute but It won't work. I don't know about spring boot debugging with remote servers. Anyway, I used jsp pages as my view to return all the data and test. That is how I testing.
This is my Controller
#RequestMapping(value = "/addwishlist", method = RequestMethod.GET)
public ModelAndView AddToWishlist(#Valid #ModelAttribute Adds add, BindingResult bindingResult, HttpSession session) {
String usrnm = (String) session.getAttribute("username");
Adds adds = addsService.getAddById(add.getAdid());
//wishlist wish = new wishlist(,,,,,usrnm);
ModelAndView model = new ModelAndView();
wishlist wish = new wishlist();
wish.setAdID(add.getAdid());
wish.setAdtitle(add.getAdtitle());
wish.setAdprice(6);
wish.setAdquantity(545);
wish.setPictureurl1(add.getPictureurl1());
wish.setUsername(usrnm);
if (wishService.WishListSave(wish)) {
return new ModelAndView("redirect:/viewishlist");
} else {
model.addObject("user", new User());
model.setViewName("login");
return model;
}
}
This is my Repository
public interface WishRepository extends CrudRepository<wishlist,Integer> {
}
This is my service package which includes Services and Service implementation
public interface WishService {
public boolean WishListSave(wishlist wish);
public boolean WishListDelete(wishlist wish);
public boolean WishlistClean(String username);
public List<wishlist> CheckWithUsername(String username);
public wishlist ViewOneWishList(String username,int adid);
}
package rego.webapp.de.repositoryservices;
import java.util.List;
import org.springframework.stereotype.Service;
import rego.webapp.de.models.wishlist;
import rego.webapp.de.repositories.WishRepository;
#Service("wishService")
public class WishServiceImpl implements WishService {
public WishRepository wishRepository;
#Override
public boolean WishListSave(wishlist wish) {
if(wish!=null)
{
wishRepository.save(wish);
return true;
}
else
{
return false;
}
}
Did I do something wrong?. According to my idea I have already done implementing , but it returns false, as in null "wish" object. I don't know why. Please help me. Thanks in advnace.:)

You're not initializing wishRepository in your service, so it is always null, and then you attempt to use it. Autowire it in from Spring in your constructor.
public class WishServiceImpl implements WishService {
private final WishRepository wishRepository;
#Autowired
public WishServiceImpl(WishRepository wishRepository) {
this.wishRepository = wishRepository;
}
// etc.
}

Try putting #Autowired on public WishRepository wishRepository;, or declare the variable as private final, create a constructor for it and mark the constructor as #Autowired

You didn't initialize public WishRepository wishRepository in your WishServiceImpl, so it is null. use #Autowired above the field, or even better, make a constructor and use #Autowired above it(for the reason to which constructor injection is better, google "field vs constructor injection"). The annotation tells spring to inject an instance to the field.

In your WishServiceImpl class mark the WishRepository with #Autowired annotation. Without this annotation container(Spring) will never know that is dependency should be injected.
From Spring version 4.3 if your class only one constructor it is not necessary to mark the constructor with #Autowired annotation.
public class WishServiceImpl implements WishService {
public WishRepository wishRepository;
// No need the annotation as this class only one constructor.
public WishServiceImpl(WishRepository wishRepository) {
this.wishRepository = wishRepository;
}
}
from Spring documentation
So as of 4.3, you no longer need to specify an explicit injection annotation in such a single-constructor scenario. This is particularly elegant for classes which otherwise do not carry any container annotations at all.

Handling REST exceptions on client's side

In a Spring MVC application I'm trying to handle an exception transferred to the client by means of rest response, but can't find any working solution.
Server side controller:
#RestController
public class MessageProducerController {
#Autowired
private MessageService service;
#RequestMapping(value = "/messageApp-api/getMessage/{id}", produces = "application/json")
public Message restGetMessage(#PathVariable long id) {
Message message = service.findSingleMessage(id).orElse(EMPTY_MESSAGE);
if (EMPTY_MESSAGE.equals(message)) {
throw new MessageNotFoundException(id);
}
return message;
}
}
Exception class:
public class MessageNotFoundException extends RuntimeException {
public MessageNotFoundException(long id) {
super(String.format("Message id=%d not found", id));
}
}
ApiError class:
public class ApiError {
private HttpStatus status;
private String message;
public ApiError(HttpStatus status, String message) {
this.status = status;
this.message = message;
}
public HttpStatus getStatus() {
return status;
}
public String getMessage() {
return message;
}
}
RestResponseException class:
#Component
#ControllerAdvice
public class RestResponseException {
#ExceptionHandler(MessageNotFoundException.class)
public ResponseEntity<Object> messageNotFound(MessageNotFoundException e) {
ApiError apiError = new ApiError(HttpStatus.NOT_FOUND, e.getMessage());
return new ResponseEntity<>(apiError, new HttpHeaders(), apiError.getStatus());
}
}
Client side controller:
#Controller
public class MessageClientController {
private static final String MESSAGE = "restMessage";
private static final String MESSAGES = "restMessages";
private static final String ERROR = "error";
#RequestMapping(value = "/messageApp-api/getMessage/{id}")
public String restGetMessage(#PathVariable long id, Model model) {
String view = MESSAGE;
try {
RestTemplate rest = new RestTemplate();
ResponseEntity<Message> response =
rest.getForEntity("http://localhost:80/messageApp-api/getMessage/{id}", Message.class, id);
if (HttpStatus.OK == response.getStatusCode()) {
model.addAttribute(MESSAGE, response.getBody());
} else if (HttpStatus.NOT_FOUND == response.getStatusCode()) {
model.addAttribute(MESSAGE, EMPTY_MESSAGE);
}
} catch (Exception e) {
e.printStackTrace();
view = ERROR;
}
return view;
}
}
The idea is to check response status and depending on it make further steps regarding model. But, in fact, rest.getForEntity("http://localhost:80/messageApp-api/getMessage/{id}", Message.class, id) throws the following exception when the message with some id was not found:

So, how to prevent an exception in the response from being thrown and how to retrieve httpStatus from the response?..

This is a misconception that I also ran into. It looks as if you can just introspect the status code in a ResponseEntity to get hold of an error. But this is not the case.
You could catch a HttpStatusCodeException which would be thrown whenever the response status code is >= 400. You can then get the status code from the exception.
try {
RestTemplate rest = new RestTemplate();
ResponseEntity<Message> response =
rest.getForEntity("http://localhost:80/messageApp-api/getMessage/{id}", Message.class, id);
model.addAttribute(MESSAGE, response.getBody());
} catch (HttpStatusCodeException e) {
if (HttpStatus.NOT_FOUND == e.getStatusCode()) {
model.addAttribute(MESSAGE, EMPTY_MESSAGE);
}
//handle other errors here
}
There are two subclasses of HttpStatusCodeException.
HttpClientErrorException is thrown for client errors (400 <= status code < 500)
HttpServerErrorException is thrown for server errors (status code >= 500)

403 Error when sending post request to external API - java

I checked out the jdoodle API, and even though it is not clear, I would say you have issues with your credentials. Perhaps a typo or you used up your credits. Can you please post the response of https://api.jdoodle.com/v1/credit-spent using your clientId and clientSecret?

I don't know much about java (more in node.js) but 403 is a forbidden message which means that you might have not given the proper authorization

Instead of sending the post to the API, log it, then post it into a JSON validator such as https://jsonlint.com/. You're not sending valid JSON, and you're getting a 403 access denied because of it.

If you didn’t add user agent in header you may get this 403 error. headers.add(“user-agent”, “Application”);
