在WebSocket中获取完整的URL

Question

I'm using one of the golang samples to build a WebSocket server. According to the samples the struct Client access websocket.Conn here and websocket.Conn has a Request method returning *http.Request.

My idea is to subscribe the user to different channels depending on the subdomain they use to enter the app.

So is it possible to get the full URL the user hit when subscribed to the websocket? Using the sample code I thought ws.Conn.Request().URL.Host would give me something like ws://channel1.lvh.me:8080/sync but instead I'm getting the path: "/chat".

Is it possible to get the full URL the user used to connect to the websocket? Thanks in advance.

Answer 1

func (*Conn) Request returns *http.Request

func (ws *Conn) Request() *http.Request

Checking the http.Request from the http package you will observe that it has a URL *url.URL type. This means that you should get the full url with:

ws.Request().URL.Path
