Synopsis

EzyHttp is a library in EzyFox ecosystem, It supports to interact to HTTP (both http server and http client)

Code Example

For full example you can take a look the examples repository

1. Start HTTP Server application

import com.tvd12.ezyhttp.core.boot.EzyHttpApplicationBootstrap;
import com.tvd12.ezyhttp.server.core.annotation.ComponentsScan;

@ComponentsScan({"packageA", "packageB"})
public class BootApp {

    public static void main(String[] args) throws Exception {
        EzyHttpApplicationBootstrap.start(BootApp.class);
    }
    
}

2. Add a controller

import com.tvd12.ezyfox.bean.annotation.EzyAutoBind;
import com.tvd12.ezyhttp.core.boot.test.data.Customer;
import com.tvd12.ezyhttp.core.boot.test.service.CustomerService;
import com.tvd12.ezyhttp.core.constant.StatusCodes;
import com.tvd12.ezyhttp.core.exception.HttpBadRequestException;
import com.tvd12.ezyhttp.core.exception.HttpNotFoundException;
import com.tvd12.ezyhttp.core.response.ResponseEntity;
import com.tvd12.ezyhttp.server.core.annotation.Controller;
import com.tvd12.ezyhttp.server.core.annotation.DoGet;
import com.tvd12.ezyhttp.server.core.annotation.DoPost;
import com.tvd12.ezyhttp.server.core.annotation.PathVariable;
import com.tvd12.ezyhttp.server.core.annotation.RequestBody;

import lombok.Setter;

@Setter
@Controller("/api/v1/customer")
public class CustomerController {

    @EzyAutoBind
    protected CustomerService customerService;
    
    @DoGet("/{zone}/{name}")
    public Customer getCustomer(@PathVariable("name") String name) {
        Customer customer = customerService.getCustomer(name);
        if(customer == null)
            throw new HttpNotFoundException("customer: " + name + " not found");
        return customer;
    }
    
    @DoPost("/add")
    public ResponseEntity addCustomer(@RequestBody Customer customer) {
        validateCustomer(customer);
        customerService.save(customer);
        return ResponseEntity.status(StatusCodes.NO_CONTENT).build();
    }
    
    protected void validateCustomer(Customer customer) {
        Map<String, String> errors = new HashMap<>();
        if(customer == null) {
            errors.put("customer", "required");
        }
        else {
            if(customer.getName() == null)
                errors.put("name", "required");
            if(customer.getAge() < 1)
                errors.put("age", "invalid");
        }
        if(errors.size() > 0)
            throw new HttpBadRequestException(errors);
    }
}

3. Add a service

import com.tvd12.ezyfox.bean.annotation.EzySingleton;
import com.tvd12.ezyhttp.core.boot.test.data.Customer;

@EzySingleton
public class CustomerService {

    protected final Map<String, Customer> customers = new HashMap<>();

    public Customer getCustomer(String name) {
        return customers.get(name);
    }

    public void save(Customer customer) {
        this.customers.put(customer.getName(), customer);
    }
}

Motivation

In an effort to bring HTTP to EzyFox ecosystem and help everyone to study one do everything
