Reconnecting after disconnect

[gilphilbert]

I'm trying to set up a persistent connection to a socketio server that might restart. If that happens, I want to reconnect without needing to redefine my methods, etc.

I've added a new item to Client to store the URL:

type Client struct {
        ....
        url string  //stores the url for this connection
        ....

And added a line to dial so it stores the URL:

func Dial(url string, tr transport.Transport) (*Client, error) {
        ...
        c.url = url 
        ...

And added a new redial function (I know it's an endless loop and it needs some waits, but it's OK for testing...)

func Redial(c *Client) {
        var err error
        tr := transport.GetDefaultWebsocketTransport()
        for {
              c.conn, err = tr.Connect(c.url)
              if err == nil {
                    break
              }
        }
        go inLoop(&c.Channel, &c.methods)
        go outLoop(&c.Channel, &c.methods)
        go pinger(&c.Channel)
}

Then, I've added this to my code:

socket.On(gosocketio.OnDisconnection, func(c *gosocketio.Channel) {
    log.Println("Disconnected from server, trying to reconnect")
    gosocketio.Redial(socket)
}

This works, other than the socket.IsAlive() method returns false. I'm so close, but I just can't seem to get this right! I'm happy if there's a much better way to handle this, but this is what I came up with. Any help would be appreciated

hi, I have solved this problem, just change your some codes

func Redial(c *Client) (*Client, error) {
var err error
tr := transport.GetDefaultWebsocketTransport()
for {
c.conn, err = tr.Connect(c.url)
if err == nil {
break
}
}
go inLoop(&c.Channel, &c.methods)
go outLoop(&c.Channel, &c.methods)
go pinger(&c.Channel)
return c, nil
}

socket.On(gosocketio.OnDisconnection, func(c *gosocketio.Channel) {
log.Println("Disconnected from server, trying to reconnect")
socket,_ = gosocketio.Redial(socket)
}
