How to get auth_method in v5 plugin?

[cjmdaixi]

Hi,

I found that v4 plugin has a method called mosquitto_auth_start which has one argument to get the auth_method from Mosquitto context. However, it seems that there is no alternative argument or interface for v5 plugin to get auth_method?

The way you should be able to do this in theory is as follows:

int auth_callback(int event, void *event_data, void *userdata)
{
    struct mosquitto_evt_extended_auth *ed = event_data;

    printf("%s\n", ed->auth_method);
    return 0;
}

Or to use mosquitto_client_auth_method(client), but unfortunately both of those methods have been missed and so don't exist.

I will add auth_method to the struct for 2.0.5, but that won't be until January now.

Well, so I have to code an independent v4 plugin to get the auth_method right now.
