Question

我将WebSocket客户端连接到具有很长查询参数的URI，如下所示：

WebSocketClient client = new WebSocketClient();
URI uri = getVeryLongUri();
WebSocketListener websocketListener = getEventListener9);
client.connect(websocketListener, uri);

使用Jetty 9.4.8.v20171121我得到：

https://stackoverflow.com/a/22472794/14731提到对于普通的HTTP客户端，必须增加请求缓冲区大小，但似乎并不是WebSocket客户端的等效配置选项。有什么想法吗？

Answer 1

我明白了。您需要将自定义HttpClient传递给WebSocketClient构造函数。

WebSocketClient client = new WebSocketClient();
client.getHttpClient().setRequestBufferSize(...);

＆＃34;请求标头太大＆＃34;打开WebSocket请求时
