Unirest

Check out the official site of Unirest at http://kong.github.io/unirest-java

In this page, I only introduce the basic usage of Unirest.

1) Install via Maven:

<dependency>

    <groupId>com.konghq</groupId>

    <artifactId>unirest-java</artifactId>

    <version>2.3.17</version>

</dependency>

HttpResponse<String> response = Unirest.get("http://httpbin.org")

                .header("Accept", "application/json")

                .queryString("flower", "lotus")    //optional request param

                .queryString("origin", "vietnam")  //optional request param

                .asString();

// Results in "http://httpbin.org?flower=lotus&origin=vietnam"

The HttpResponse<type> inside diamond bracket can be:

String: if you want to get the reponseBody as plain String (good for mapping to the Object, as the ObjectMapper usually takes String as the input argument.
JsonNode: if you want to parse the responseBoby to Json Node (good for debugging).

HttpResponse<String> httpResponse = Unirest.post("http://longdothanh.com")

        .body("JSON body")

        .header("Content-Type", "application/json")

        .asString();

Unless you specify otherwise the default Content-Type is text/plain; charset=UTF-8

Unirest.post("http://httpbin.org")

       .field("flower", "lotus")

       .field("origin", "vietnam")

       .asEmpty();

  // This will post a simple name-value pair body the same as a HTML form. This looks like

  // `flower=lotus&origin=vietnam'
