I'm testing the newest version of sgcWebSockets in Delphi to try to connect to a socket.io server.
The server I'm connecting to is using this type of auth:
https://socket.io/docs/v4/client-options/#auth
I can't see any documentation that this type of auth is supported. I've tried using TsgcWebSocketClient Authentication.Token, but that doesn't seem to work with this type of auth.

Hello,
It seems this auth requires to pass the token when opening the http request to get a new session, so you should use the event OnHTTPRequest of the Socket.io API, find below how to pass a bearer token example, just replace "your-token" by the correct value
If doesn't work, and you can provide the server where you must connect please provide more details and I'll check in my machine.
Kind Regards,
Sergio

procedure OnHTTPRequest(Sender: TObject; aRequest: TsgcWSSocketIOHTTPRequest);
begin
aRequest.Headers.Add('Authorization: Token your-token');

Hi. It's not a part of the headers. It's sent during the CONNECT in the protocol. See the example here under 'with an additional payload':
https://socket.io/docs/v4/socket-io-protocol/#connection-to-a-namespace
https://socket.io/docs/v4/socket-io-protocol/#connection-to-a-namespace
It is possibly also a part of the handshake outside of the header. See info here:
https://socket.io/docs/v4/server-socket-instance/#sockethandshake
Similar to the HandShakeTimestamp you've already implemented.

Hello,
The Socket handshake is just an HTTP GET request with some parameters. According the url:
https://socket.io/docs/v4/server-socket-instance/#sockethandshake
The Auth is passed as a payload, but a HTTP GET request hasn't a payload, it's not a POST, so I assume they are referring to pass an Authorization header like in the example I've sent previously. Did you tested it? it doesn't work?

No. The auth is in the payload when connecting to the namespace. See info in the socket io code:
https://github.com/socketio/socket.io/blob/main/packages/socket.io-client/lib/socket.ts
https://github.com/socketio/socket.io/blob/main/packages/socket.io-client/lib/socket.ts
/**
* the authentication payload sent when connecting to the Namespace
*/
auth?: { [key: string]: any } | ((cb: (data: object) => void) => void);
/**
* Credentials that are sent when accessing a namespace.
*
* @example
* const socket = io({
* auth: {
* token: "abcd"
* }
* });
*
* // or with a function
* const socket = io({
* auth: (cb) => {
* cb({ token: localStorage.token })
* }
* });
*/
public auth: { [key: string]: any } | ((cb: (data: object) => void) => void);
Hi,
I've added a new property "HandShakeAuthToken" to set the Authentication token. Find attached a compiled sample that use this new feature.

Ok. It seems to work with the sample. When will the trial version for Delphi be updated so we can test this further?
Next month will be a new release, but I can compile a trial with this feature if you tell me which is your delphi version.
Find below the link to download the trial for D11

Ok. Thanks. The auth now works as expected. We also need to use query parameters. Is that something that you have support for?

I'm trying to send a string array and it doesn't seem to work, like this:
Tired with
and various other similar combinations, but nothing seem to work
const socket = io({
query: {
arr: ['a', 'b']
}
});
Tired with
WSSocketIO.SocketIO.Parameters := '&arr=[''a'',''b'']';
WSSocketIO.SocketIO.Parameters := '&arr=["a","b"]';
WSSocketIO.SocketIO.Parameters := '&arr=%5B%27a%27,%27b%27%5D';
and various other similar combinations, but nothing seem to work
Hi,
Send without "[]" characters
sgcEncodeURIComponent function makes uses of the sgcBase_Helpers unit.
Kind Regards,
Sergio
