403 Error when sending post request to external API

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.

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”);

Is it possible to use the "findbyId" method in ingiteRepository?

I want to use IgniteRepository and query method.
The "save" method and "findAll" method is okay, but when I try to find data by id, I have trouble to use "findById" method.
Is it possible to use query method by ignite repository?
(Ignite cache uses Key-Value format. I also wonder the id at the "findById" in IgniteRepository, means whether key or #id in value.)
Following is error message.

Yes some of the methods are not supported yet. Please refer this and this links for more details.
But you can achieve all of them by making use of cache APIs along with IgniteRepository APIs like below,
#RequestMapping("/persons")
#RestController
public class PersonRestController {
#Autowired
private Ignite ignite;
#Autowired
private PersonRepository ps;
private IgniteCache<Integer, Person> personCache;
#PostConstruct
private void postConstruct() {
personCache = ignite.cache("person-cache");
}
#GetMapping("/count")
public Long count() {
return ps.count();
}
#GetMapping
public Iterable<Person> findAll() {
return ps.findAll();
}
#GetMapping("/{id}")
public Person findById(#PathVariable Integer id) {
return personCache.get(id);
}
#DeleteMapping("/{id}")
public boolean deleteById(#PathVariable Integer id) {
return personCache.remove(id);
}
}
Please refer this and this links for complete working application source code
Thank you!

How to implement a REST service with Spring Boot

I want to build a simple microservice with "Spring Boot" with IntelliJ IDE.
One method of this microservice should to accept in input a List and a Double Value.
So I'm building this code:
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
#RestController
public class ECGController {
private double v1 = 0.01;
private double v2 = 0.01;
private int il = 0;
private static final double step = 0.0025;
#PostMapping("/clearF3A")
public List<Double> clearF3A(ArrayList<Integer> RRin, Double CR){
try{
}catch(Exception e){
}
}
In postman I'm try to execute this:
{
"RRin":[
834,
490,
878,
807,
517,
849,
816,
520,
632,
488,
701,
536,
675
],
"CR":2.0
}
but if I try to execute this request, I can display this message error:

java.lang.NullPointerException

Your request is bad.
Instead of providing ArrayList<Integer> RRin, Double CR to clearF3A function, you should have one object that represents whole post body (whole JSON document). That is the rule. In your case, your passed object should have two parameters, one is rrin array, and second one should be cr. Also, that parameter should be annotated with #RequestBody
Roughly, this is what you need to have:
#PostMapping("/clearF3A")
public List<Double> clearF3A(#RequestBody ClearF3ARequest){
...
}
class ClearF3ARequest {
private ArrayList<Integer> RRin;
private Double CR;
}
Hope this helps.

Create a new object to represent your JSON structure. For example:
public class EcgInput {
#JsonProperty("RRin")
private List<Integer> rrIn;
#JsonProperty("CR")
private Double cr;
//todo: add the getters and setters and methods like toString()
}
public class EcgOutput {
#JsonProperty("output")
private List<Double> output;
//todo: add the getters and setters and methods like toString()
}
Then in your controller change your method to something like:
#PostMapping("/clearF3A")
public ResponseEntity<EcgOutput> clearF3A(#RequestBody EcgInput ecgInput) {
//todo: your logic
EcgOutput output = new EcgOutput();
//todo: put your result inside it
return new ResponseEntity<>(output, HttpStatus.OK);
}
Jackson will translate JSON to those objects, and vice-versa for you.

Here is the service file :
package com.test.Service;
import com.test.Dao.StudentsDao;
import com.test.Entity.Student;
import org.springframework.stereotype.Service;
import java.util.Collection;
#Service
public class StudentService {
private StudentsDao studentDao;
public Collection<Student> getAllStudents()
{
return studentDao.getAllStudents();
}
}
The controller file :
package com.test.Controller;
import com.test.Entity.Student;
import com.test.Service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.util.Collection;
#RestController
#RequestMapping("/students")
public class StudentController {
#Autowired
private StudentService studentservice;
#RequestMapping(method = RequestMethod.GET)
public Collection<Student> getAllStudents()
{
return studentservice.getAllStudents();
}
}
And finally the DAO file :
package com.test.Dao;
import com.test.Entity.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import java.util.Collection;
import java.util.HashMap;
import java.util.Map;
#Repository
public class StudentsDao {
#Autowired
public static Map<Integer, Student> students;
static{
students = new HashMap<Integer, Student>(){
{
put(1, new Student(1, "Chadi", "Informatique"));
}
};
}
public Collection<Student> getAllStudents()
{
return this.students.values();
}
}
What's causing this error . And how can i fix it ?

at com.test.Service.StudentService.getAllStudents(StudentService.java:15) ~[classes/:na] says it all. Check the line 15 from StudentService ... there you have a null :)
Your DAO is null .. you forgot the #Autowired on the dao field

You are using a class that is annotated with #repository in your service class. So the spring framework already knows that the DAO class is bean. But instead of using the bean, you’re defining an object of class without initializing the value for it. So, you will got a null pointer exception.

VaadinSession failing in Spring Boot application

I'm trying to make a simple Vaadin application integrated with Spring Boot / Spring Session / Spring Security, nothing too fancy since the client requirements aren't that demanding. I managed to set up a basic environment with Spring Session JDBC and added a couple of Views.
#SpringUI
#SpringViewDisplay
public class MyUI extends UI implements ViewDisplay {
private Panel springViewDisplay;
private static final long serialVersionUID = -5326618953003021331L;
#Override
protected void init(VaadinRequest request) {
final VerticalLayout root = new VerticalLayout();
root.setSizeFull();
setContent(root);
final CssLayout navigationBar = new CssLayout();
navigationBar.addStyleName(ValoTheme.LAYOUT_COMPONENT_GROUP);
navigationBar.addComponent(createNavigationButton("Nómina",
DefaultView.VIEW_NAME));
navigationBar.addComponent(createNavigationButton("Empleados",
EmpleadosAdminView.VIEW_NAME));
root.addComponent(navigationBar);
springViewDisplay = new Panel();
springViewDisplay.setSizeFull();
root.addComponent(springViewDisplay);
root.setExpandRatio(springViewDisplay, 1.0f);
}
}
The DefaultView loads fine:
#SpringView(name = DefaultView.VIEW_NAME)
public class DefaultView extends VerticalLayout implements View {
public static final String VIEW_NAME = "";
private static final long serialVersionUID = 3600517630040771693L;
#PostConstruct
void init() {
addComponent(new Label("Default view"));
}
#Override
public void enter(ViewChangeListener.ViewChangeEvent event) {
// This view is constructed in the init() method()
}
}
The second view, however, throws the following exception when accessing it:
#SpringView(name = EmpleadosAdminView.VIEW_NAME)
public class EmpleadosAdminView extends VerticalLayout implements View {
public static final String VIEW_NAME = "empleados";
private static final long serialVersionUID = 3344332615518673282L;
private final EmpleadoRepository empleadoRepository;
private final EmpleadosEditor empleadosEditor;
private final Grid<Empleado> grid;
private final TextField filter;
private final Button addNewEmpleado;
#Autowired
public EmpleadosAdminView(EmpleadoRepository empleadoRepository, EmpleadosEditor empleadosEditor) {
this.empleadoRepository = empleadoRepository;
this.empleadosEditor = empleadosEditor;
this.grid = new Grid<>(Empleado.class);
this.filter = new TextField();
this.addNewEmpleado = new Button("Agregar nuevo empleado", VaadinIcons.PLUS);
}
private void listEmpleados(String filterText) {
if (StringUtils.isEmpty(filterText)) {
grid.setItems(empleadoRepository.findAll());
} else {
grid.setItems(empleadoRepository.findByNombreIgnoreCase(filterText));
}
}
#Override
public void enter(ViewChangeListener.ViewChangeEvent event) {
HorizontalLayout actions = new HorizontalLayout(filter, addNewEmpleado);
VerticalLayout mainLayout = new VerticalLayout(actions, grid, empleadosEditor);
addComponent(mainLayout);
grid.setHeight(300, Unit.PIXELS);
grid.setColumns("id", "nombre", "cedula");
filter.setPlaceholder("Filtrar por nombre");
filter.setValueChangeMode(ValueChangeMode.LAZY);
filter.addValueChangeListener(e -> listEmpleados(e.getValue()));
grid.asSingleSelect().addValueChangeListener(e ->
empleadosEditor.editEmpleado(e.getValue())
);
addNewEmpleado.addClickListener(e -> empleadosEditor.editEmpleado(new Empleado()));
empleadosEditor.setChangeHandler(() -> {
empleadosEditor.setVisible(false);
listEmpleados(filter.getValue());
});
listEmpleados(null);
}
}

I'm basing my code on these tutorials:
http://vaadin.github.io/spring-tutorial/
https://spring.io/guides/gs/crud-with-vaadin/
Not sure what I'm doing wrong, or if there's some configuration I need to revise. The basic authentication configuration is this:
JDBCHttpSessionConfig.java
#Configuration
#EnableJdbcHttpSession
public class JdbcHttpSessionConfig {
}
SecurityConfig.java
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger LOG = LoggerFactory.getLogger(SecurityConfig.class);
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable() // Use Vaadin's CSRF protection
.authorizeRequests().anyRequest().authenticated() // User must be authenticated to access any part of the application
.and()
.httpBasic();
}
#Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/css/*"); // Static resources are ignored
}
}

The following line from the log reveals the core problem:
2018-03-20 19:07:21.222 WARN 13380 --- [nio-8080-exec-3] com.vaadin.event.ListenerMethod : Error in serialization of the application: Class com.tomasa.nomina.ui.EmpleadosEditor$$Lambda$658/1513980400 must implement serialization.
Since JdbcOperationsSessionRepository uses standard Java serialization while storing the sessions, you have to ensure that the attributes you put in session implement Serializable. In your case class com.tomasa.nomina.ui.EmpleadosEditor$$Lambda$658/1513980400 looks like the offender that doesn't comply with that requirement.
You should probably double check your app for all the objects that end up placed in session and have them implement Serializable contract.
