當然,Restlet框架提供了許多示例代碼,以幫助開發者快速上手并理解其使用方法。以下是一些示例代碼的簡要介紹:
public class MyResource extends ServerResource {
@Override
protected void doGet() throws ResourceException {
String name = getRequest().getFirstHeader("name").getValue();
if (name == null) {
name = "World";
}
getResponse().setEntity("Hello, " + name + "!");
}
@Override
protected void doPost(Request request, Response response) throws ResourceException {
String name = request.getParameter("name");
if (name != null) {
getResponse().setEntity("Hello, " + name + "!");
} else {
getResponse().setStatus(Response.Status.BAD_REQUEST);
}
}
}
Router router = new Router(getContext());
router.attach("/users", MyResource.class);
public class MyFilter implements Filter {
@Override
public void filter(FilterChain chain) throws IOException, ServletException {
String authHeader = getRequest().getFirstHeader("Authorization").getValue();
if (authHeader == null || !authHeader.startsWith("Bearer ")) {
chain.cancel();
getResponse().setStatus(Response.Status.UNAUTHORIZED);
return;
}
chain.doFilter(getRequest(), getResponse());
}
}
以上示例代碼展示了Restlet框架的基本用法和功能。當然,實際應用中可能需要更復雜的邏輯和配置,但這些示例代碼可以作為起點進行擴展和學習。
