Introduction to the Httpz Framework in Java Class Libraries

Introduction to the Httpz Framework in Java Class Libraries Httpz is a lightweight HTTP client library based on Java that provides an easy-to-use API for sending HTTP requests and processing HTTP responses. Its goal is to enable developers to communicate with web services in a simple and intuitive manner. Httpz provides the following main functions: 1. Sending HTTP requests: Httpz can send various types of HTTP requests, including GET, POST, PUT, DELETE, etc. By providing information such as URL, request method, request header, and request body, HTTP requests can be easily created and sent. Here is an example of sending a GET request: HttpResponse response = Httpz.get("https://api.example.com/users") .param("page", "1") .param("limit", "10") .header("Authorization", "Bearer token") .execute(); 2. Handling HTTP responses: Httpz provides a simple and flexible API to handle HTTP responses. Information such as response status codes, response headers, and response bodies can be obtained. The following is an example of processing HTTP responses: int statusCode = response.getStatusCode(); Map<String, String> headers = response.getHeaders(); String body = response.getBody(); 3. Support for asynchronous requests: Httpz supports sending asynchronous HTTP requests and provides a callback mechanism to handle asynchronous request responses. The following is an example of sending an asynchronous GET request: Httpz.get("https://api.example.com/users") .param("page", "1") .param("limit", "10") .header("Authorization", "Bearer token") .executeAsync(new AsyncCallback() { @Override public void onSuccess(HttpResponse response) { //Successfully processed response } @Override public void onFailure(Exception ex) { //Processing request failed } }); 4. Support file upload and download: Httpz can easily upload files to or download files from the server. This can be achieved by specifying a file path or using Java's File object. The following is an example of file upload: HttpResponse response = Httpz.post("https://api.example.com/upload") .header("Authorization", "Bearer token") .part("file", new File("path/to/file")) .execute(); In summary, Httpz is a powerful and easy-to-use Java class library that can be used to easily send HTTP requests and process HTTP responses. Whether it's making simple API calls or interacting with complex web services, Httpz can provide a simple and efficient solution.
