在vertx中创建cookie
在vertx中创建cookie
提问于 2017-01-06 16:30:05
我想用vertx创建一个简单的cookie。
import io.vertx.core.AbstractVerticle;
import io.vertx.core.http.HttpHeaders;
import io.vertx.core.http.HttpServer;
import io.vertx.core.http.HttpServerRequest;
import io.vertx.core.http.HttpServerResponse;
import io.vertx.ext.web.Cookie;
import io.vertx.ext.web.Router;
import io.vertx.ext.web.RoutingContext;
import java.util.Date;
public class HttpVerticle extends AbstractVerticle {
@Override
public void start() throws Exception {
HttpServer server = vertx.createHttpServer();
Router router = Router.router(vertx);
router.route("/opt-out").handler(this::optOut);
System.out.println("Server started @ 3000");
server.requestHandler(router::accept).listen(3000);
}
public void optOut(RoutingContext context) {
HttpServerRequest request = context.request();
HttpServerResponse response = context.response();
response.putHeader("content-type", "text-plain");
response.setChunked(true);
response.write("hellow world");
Cookie cookie = Cookie.cookie("foo", "bar");
context.addCookie(cookie);
response.end();
}
}但当我查看浏览器时，我看到的不是带有"foo“名称的cookie，其值是"bar”。我做错了什么？
另外，我如何访问所有已标记的cookies？

这就是在Vertx中设置cookie的方式。
@Override
public void start(Future<Void> future) {
Router router = Router.router(vertx);
router.route().handler(CookieHandler.create());
router.get("/set-cookie").handler(this::setCookieHandler);
}
public void setCookieHandler(RoutingContext context) {
String name = "foo";
String value = "bar";
long age = 158132000l; //5 years in seconds
Cookie cookie = Cookie.cookie(name,value);
String path = "/"; //give any suitable path
cookie.setPath(path);
cookie.setMaxAge(age); //if this is not there, then a session cookie is set
context.addCookie(cookie);
context.response().setChunked(true);
context.response().putHeader(HttpHeaders.ACCESS_CONTROL_ALLOW_ORIGIN, "*");
context.response().putHeader(HttpHeaders.ACCESS_CONTROL_ALLOW_METHODS, "GET");
context.response().write("Cookie Stamped -> " + name + " : " +value);
context.response().end();
}谢谢。

首先，您需要在路由器中添加CookieHandler。
这是addCookie方法的JavaDoc：
router.route().handler(CookieHandler.create());/**
* Add a cookie. This will be sent back to the client in the response. The context must have first been
* to a {@link io.vertx.ext.web.handler.CookieHandler} for this to work.
*
* @param cookie the cookie
* @return a reference to this, so the API can be used 因此，在响应中使用".end()“方法，而不是".write()”
response.end("hellow world");页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
