To automate the subscription approval you will need a rule that selects on wrangler inbound_pending_subscription_added event which raises a wrangler pending_subscription_approval event with channel_name attribute set to the channel_name of the inbound_pending_subscription_added event, this can be done by passing the attributes along.
rule autoAccept {
select when wrangler inbound_pending_subscription_added
pre{
attributes = event:attrs().klog("subcription :");
}
noop();
always{
raise wrangler event "pending_subscription_approval"
attributes attributes;
log("auto accepted subcription.");
}
}
Security Issues
The preceding code shows a simple example of approving subscriptions automatically. This code, installed in a pico, would automatically subscribe to every pico that requests it.
Production code should be more circumspect about what subscriptions it accepts. For example, a pico might automatically accept any subscription request from its parent. Or any subscription request that contains a specific password.
