Can Vertx Web client synchronize

[crazyliu]

I'd like to nest Vert.x Web Client in Vertx-web and get the results.

Hi,

Do you mean something like this:

package io.vertx.hello;

import io.vertx.core.AbstractVerticle;

import io.vertx.ext.web.RoutingContext;

import io.vertx.ext.web.client.WebClient;

import io.vertx.ext.web.Router;

public class HelloVerticle extends AbstractVerticle {

WebClient client;

@Override

public void start() {

client = WebClient.create(vertx);

Router router = Router.router(vertx);

router.get("/").handler(this::getHelloMessage);

vertx.createHttpServer()

.requestHandler(router::accept)

.listen(8080);

}

private void getHelloMessage(RoutingContext routingContext) {

client.get(80, "perdu.com", "/")

.send(ar -> {

if (ar.succeeded()) {

routingContext.response().end(ar.result().bodyAsBuffer());

} else {

routingContext.fail(ar.cause());

}

});

}

}

Thank you very much, I've tried your Java code.

But when I try to put it in the JavaScript, I fail, the request can't end, this is my Code：

   

var Router = require("vertx-web-js/router");
var LoggerHandler = require("vertx-web-js/logger_handler");
var BodyHandler = require("vertx-web-js/body_handler");
var WebClient = require("vertx-web-client-js/web_client");
var server = vertx.createHttpServer();
var client = WebClient.create(vertx);
var router = Router.router(vertx);
router.route().handler(LoggerHandler.create().handle);
router.route().handler(BodyHandler.create().handle);
router.post("/sendMessage").handler(function (ctx) {
  client.post(80, "127.0.0.1", "/helloWorld").sendForm(ctx.request().params(), function (ar, ar_err) {
    if (ar_err == null) {
      console.log("Received response with status code: " + ar.statusCode() + " with body: " + ar.body());
      ctx.response().end(ar.result().bodyAsBuffer());
    } else {
      console.log("Something went wrong: " + ar_err.getMessage());
      ctx.fail(ar.cause());
    }
  });
});
server.requestHandler(router.accept).listen(8058);

Can you create a reproducer on GitHub ? Thanks

Thanks for attention, the program has been successfully run, the error is due to the return value format
