How to make a GET request in AEM using Apache Fluent

In this post, I am making a service of GET request and using that service in a servlet to show the data.

API URL = https://thesimpsonsquoteapi.glitch.me/quotes

We will hit this URL to get our data inside a service and using Apache Fluent and converting into formatted JSON using Jackson.

Service 

import com.fasterxml.jackson.databind.ObjectMapper;

import org.osgi.service.component.annotations.Component;

import org.apache.http.client.fluent.Request;

import java.io.IOException;

@Component(service = ApiService.class, immediate = true)

public class ApiService {

    private static final String apiUrl = “https://thesimpsonsquoteapi.glitch.me/quotes”;

    public String getJson() throws IOException {

        private String content;

        content = Request.Get(apiUrl).execute().returnContent().toString();

        ObjectMapper mapper = new ObjectMapper();

        Object json = mapper.readValue(content, Object.class);

        String indentedContent = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(json);

        return indentedContent;

    }

}

Servlet

import com.infield.aem.challenge.core.services.ApiService;

import org.apache.sling.api.SlingHttpServletRequest;

import org.apache.sling.api.SlingHttpServletResponse;

import org.apache.sling.api.servlets.SlingSafeMethodsServlet;

import org.osgi.service.component.annotations.Component;

import org.osgi.service.component.annotations.Reference;

import javax.servlet.Servlet;

import java.io.IOException;

import java.io.PrintWriter;

@Component(service = Servlet.class, property = {“service.description=Api Servlet”,

        “sling.servlet.paths=/bin/api.json”,

        “sling.servlet.extensions=json”

})

public class ApiServlet extends SlingSafeMethodsServlet {

    // calling the service using @Reference annotation.

    @Reference

    private ApiService apiService;

    @Override

    protected void doGet(final SlingHttpServletRequest req, final SlingHttpServletResponse response) throws IOException {

        PrintWriter out = response.getWriter();

        out.println(apiService.getJson());

    }

}

After that build your project on your local AEM instance and hit URL—

http://localhost:4502/bin/api.json

Then the output will be shown like this

Note –> Data in JSON can be random.
