Vert.x websocket 客户端 - 400 错误请求

Question

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

问题是 Vert.x 没有提供仅与 WsURI as Node.JS does 连接的方法。我必须指定端口和主机并获得 HTTP 400 Bad Request 异常。

使用 Node.js 你可以：

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

有了Vert.x你必须做

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 -> { ...});

Answer 1

此 HttpClient#websocket 方法将相对 URI 作为第三个参数。

您应该可以这样连接：

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

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