Installing

Install your specific service package with the following command.

GoPath

You can install the entire SDK to GoPath by go get:

$ go get github.com/MapleLove2014/talos-sdk-golang

Go modules

Or add the module to your go.mod:

go mod edit -require=github.com/MapleLove2014/talos-sdk-golang@v0.2.12

Tutorial

We have an Tutorial Demo in package example/, here we choose talos_consumer to explain the use process

import

To use SDK, import like this:

import (
	"github.com/MapleLove2014/talos-sdk-golang/consumer"
	"github.com/MapleLove2014/talos-sdk-golang/utils"
	log "github.com/sirupsen/logrus"
)

Configuration profile

Reference talosConsumer.conf, you can configure like this:

galaxy.talos.service.endpoint=ENDPOINT

galaxy.talos.topic.name=MY-TOPIC

galaxy.talos.access.key=MY-APP-KEY

galaxy.talos.access.secret=MY-SECRET-KEY

Notice

Before using the Talos SDK, ensure that you've correct credential and base information
Other configurations can remain the default

Coding

    // user can customize log format or use default format
    // log.SetOutput(os.Stdout)
    // log.SetLevel(log.InfoLevel)
    utils.InitLog()
    
    // init properties from talosConsumer.conf
    var propertyFilename string
    flag.StringVar(&propertyFilename, "conf", "talosProducer.conf", "conf: talosConsumer.conf'")
    flag.Parse()
    
    // constructor
    talosConsumer, err := consumer.NewTalosConsumerByFilename(propertyFilename, 
        NewMyMessageProcessorFactory(),
        client.NewSimpleTopicAbnormalCallback())
    if err != nil {
        log.Errorf("init talosConsumer failed: %s", err.Error())
        return
    }
    
    // shutdown, graceful exit
    go func() {
        time.Sleep(5 * time.Second)
        talosConsumer.ShutDown()
    }()
    
    // block main function and wait shutdown
    talosConsumer.WaitGroup.Wait()

Go run & Go build

Then user can run this demo to fetch data

$ go run $path/TalosConsumerDemo.go [-config] [$path/talosConsumer.conf]

$ cd example/talos_consumer
$ go build TalosConsumerDemo.go
$ ./TalosConsumerDemo [-config] [$path/talosConsumer.conf]
