Vert.x websocket 客户端 - 400 错误请求

问题描述

如何从我的 Java verticles 连接 Cex.IO websocket API?em>

问题是 Vert.x 没有为我提供只与 WsURI 连接的方法 就像 Node.JS 一样.我必须指定端口和主机并获得 HTTP 400 错误请求异常.

The problem is that Vert.x doesn't provide me with a way to connect only with WsURI as Node.JS does. I have to specify port and host and get HTTP 400 Bad Request exception.

使用 Node.js，您可以:

With Node.js you do:

var WebSocketClient = require('websocket').client;
var client = new WebSocketClient();
client.connect("wss://ws.cex.io/ws/");

使用 Vert.x，您必须做到

With Vert.x you have to do

int host = 443; // That's defaults
String host = "cex.io"; // Am I right by specifying this host?
HttpClient client = Vertx.vertx().createHttpClient();
client.websocket(port, host, "wss://ws.cex.io/ws/", ws -> { ...});

推荐答案

这个 HttpClient#websocket 方法将相对 URI 作为第三个参数.

This HttpClient#websocket method takes a relative URI as third parameter.

您应该能够像这样连接:

You should be able to connect like this:

client = vertx.createHttpClient(new HttpClientOptions()
  .setDefaultHost("ws.cex.io")
  .setDefaultPort(443)
  .setSsl(true));

client.websocket("/ws", ws -> {
  // Work with the websocket
});
