示例1: ConnectWebsocketSession
// ConnectWebsocketSession dials the remote specified in the opts and
// creates new websocket session.
func ConnectWebsocketSession(opts *DialOptions) (*WebsocketSession, error) {
dialURL, err := url.Parse(opts.BaseURL)

return nil, err
}
// will be used to set the origin header
originalScheme := dialURL.Scheme
if err := replaceSchemeWithWS(dialURL); err != nil {
return nil, err
}
if err := addMissingPortAndSlash(dialURL); err != nil {
return nil, err
}
serverID := threeDigits()
sessionID := utils.RandomString(20)
// Add server_id and session_id to the path.
dialURL.Path += serverID + "/" + sessionID + "/websocket"
requestHeader := http.Header{}
requestHeader.Add("Origin", originalScheme+"://"+dialURL.Host)
ws := websocket.Dialer{
ReadBufferSize: opts.ReadBufferSize,
WriteBufferSize: opts.WriteBufferSize,

// is of *http.Transport type - we're using its Dial field
// for connecting to remote host

// use ws.HandshakeTimeout for the deadlines.
