events of json type don't have their Content-Type header set

[regner]

Sample code:

// Setup, connection handling, etc.

b := bytes.NewBufferString("event json DTMF\n")
b.WriteTo(conn)

// Some other code and then this runs in a goroutine for us

for {
    msg, err := conn.ReadMessage()

    // For JSON events this ends up being ""
    msgType := msg.GetHeader("Content-Type")

    switch msgType {
    case "text/disconnect-notice":
        done <- true
    case "text/event-plain":
        // assuming "event plain DTMF" is sent instead of JSON this will trigger
    case "text/event-json":
        // This will never trigger
    }

    //This is my current hack
    if eventName, ok := msg.Headers["Event-Name"]; ok {
        switch eventName {
        case "DTMF":
            logger.Errorf("DTMF: %s", msg.Headers["DTMF-Digit"])
        }
    }
}
