The jQuery client will be accessed by opening the consume-restful-webservice-jquery.html file in your browser, and will consume the service accepting requests at:

http://rest-service.guides.spring.io/greeting

The service will respond with a JSON representation of a greeting:

{
    "id": 166,
    "content": "Hello, World!"
}

The jQuery client will render the ID and content into the DOM.

consume-rest.js
$(document).ready(function () {
    $.ajax({
        url: "http://rest-service.guides.spring.io/greeting",
        success: function (data) {
            $("#id").append(data.id);
            $("#content").append(data.content);

        },
        error: function (xhr, ajaxOptions, thrownError) {
            alert(xhr.responseText + "\n" + xhr.status + "\n" + thrownError);
        }
    });

});

Create the HTML page that will load the client into the user’s web browser:

consume-restful-webservice-jquery.html
<!DOCTYPE html>
<html>
    <head>
        <title>How to consume RESTful Web Service using jQuery</title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
        <script src="js/consume-rest.js"></script>
    </head>
    <body>
        <div>
            <h3>How to consume RESTful Web Service using jQuery</h3>

            <p id="id">ID: </p>
            <p id="content">Content: </p>

        </div>
    </body>
</html>

Run the HTML file in your favorite web browser and you will get the result as shown below.
