Getting JSON data from server running on localhost

Question

I'm trying to do some API testing but I'm not sure how to get started. Like in Java, how could I read in the response of a server for example:

localhost:3000/ping

the response is:

{
    "status": "success",
    "data": {
        "alive": true
    }
}

Looks like httpclient is no longer being developed, so I looked into REST-Assured ( https://code.google.com/p/rest-assured/ ). My question is, how could I translate this to javacode? I was looking at httpclient, but I don't even know how to use it. Any help will be much appreciated, thanks much!

Answer 1

import com.jayway.restassured.RestAssured.*;
import com.jayway.restassured.matcher.RestAssuredMatchers.*;
import org.hamcrest.Matchers.*;

public class TestRest {
    public void doTest() {
        String json = given().port(3000).get("/ping").toString();
        System.out.println(json);
    }
}

To import library into maven:

<dependency>
      <groupId>com.jayway.restassured</groupId>
      <artifactId>rest-assured</artifactId>
      <version>2.3.3</version>
      <scope>test</scope>
</dependency>

Edit

To do this without static references:

import com.jayway.restassured.RestAssured;

public class testAPI {
    public void doTest() {
        String json = RestAssured.given().port(3000).get("/ping").toString();
        System.out.println(json);
    }
}
