Gatling：WebSocketHandshakeException：握手响应无效 getStatus：400 错误请求

Question

我正在尝试打开 ws 连接，但出现错误：

val openConnection = exec( ws("Connect -> WS").wsName("user").connect("wss://socket.develop.test.com?access_token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9"))

然后，我得到：

09:49:53.343 [DEBUG] i.g.h.c.i.DefaultHttpClient - Installing SslHandler for wss://socket.develop.test.com?access_token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9

        at io.netty.handler.codec.http.websocketx.WebSocketClientHandshaker13.verify(WebSocketClientHandshaker13.java:267)

在gatling.conf中，我还设置了：

enableSni = false
useOpenSsl = false
enableHostnameVerification = false

如果我尝试打开与任何 WS 客户端（如 SmartWebsocketClient）的连接 - 一切正常，但通过加特林我无法打开连接。有什么解决办法吗？

Answer 1

wss://domain?access_token... 不是有效的 URL。路径组件必须以 / 而不是 ? 开头。这意味着请求无效，这可以解释 400 Bad Request.

的响应

URL 必须至少为 wss://domain/?access_token...（即 ? 之前的 /），但 URL 的其余部分可能出乎意料服务器也是。请检查服务器的实际要求。

Answer 2

这是 Netty 中的一个错误，当路径为空时无法正确计算 WebSocket 握手请求 url。我刚刚贡献了一个补丁：https://github.com/netty/netty/pull/10095。 Gatling 中的同级问题：https://github.com/gatling/gatling/issues/3876
