Java WebApp Utilities

A collection of utility classes frequently used in building a web application

HttpUtil

Used in sending requests (e.g. get, post, put, delete) to a url resource. Every methods returns Apache's HttpResponse object. With this object, we can get the status code, headers, and content of the response.

Methods:

HttpUtil.post(String url, Map<String, String> params);

HttpUtil.get(String url, Map<String, String> params);

HttpUtil.get(String url, Map<String, String> params, Map<String, String> headers);

HttpUtil.postJson(String url, String jsonData, Map<String, String> headers);

HttpUtil.delete(String url, Map<String, String> headers);

To get the String content of the HttpResponse, use the method:

HttpUtil.getContent(HttpResponse response); //returns the string content of the response

To get the status code of the response, use the statement

response.getStatusLine().getStatusCode(); //returns int code
