})
.handler("/hello", (ctx, req) -> {
var res = new HashMap();
res.put("req", req);
ctx.render("playground.ftl", res); // 模版渲染
})
.handler("/world", (ctx, req) -> {
ctx.redirect("/hello"); // 302跳转
})
.handler("/error", (ctx, req) -> {
ctx.abort(500, "wtf"); // 异常
})
.resource("/pub", "/static") // 静态资源
.child("/user", () -> { // 路由嵌套

ctx.html("Hello, World");
})
.handler("/hello.json", (ctx, req) -> {
ctx.json(new String[] { "Hello", "World" });
})
.filter((ctx, req, before) -> { // 过滤器、拦截器
if (before) {
System.out.printf("before %s\n", req.path());
} else {
System.out.printf("after %s\n", req.path());
}
return true;
});
});
var rd = new KidsRequestDispatcher("/kids", router); // 请求派发器
rd.templateRoot("/tpl"); // 模版classpath根目录
rd.exception(500, (ctx, e) -> { // 异常处理
ctx.html("what the fuck it is", 500);
})
.exception((ctx, e) -> { // 通用异常处理
ctx.html("mother fucker!", e.getStatus().code());
});
var server = new HttpServer("localhost", 8080, 2, 16, rd);
server.start();
Runtime.getRuntime().addShutdownHook(new Thread() {
public void run() {
server.stop(); // 优雅停机
}
});
