Redis Sub Endpoint

Redis Endpoint v0.22.0+ is used to create and start a Redis subscription service. It can subscribe to data on different topics and then route it to different rule chains for processing.

TIP

This component is an extension component, and you need to import an additional extension library: rulego-components (opens new window)

# Type

endpoint/redis

# Startup Configuration

This component allows the reuse of shared connection clients through the server field. See Component Connection Reuse for reference.

Field	Type	Required	Description	Default Value
server	string	Yes	redis server address	None
password	string	No	Password	None
db	string	No	db index	0

# Response

Before responding with exchange.Out.SetBody, you need to specify the responseTopic parameter through exchange.Out.Headers() or exchange.Out.Msg.Metadata. The component will then respond with data to the specified topic:

exchange.Out.GetMsg().Metadata.PutValue("responseTopic", "device.msg.response")
// or
exchange.Out.Headers().Add("responseTopic", "device.msg.response")
exchange.Out.SetBody([]byte("ok"))
