云项目中提供消息订阅功能,当项目中的设备相关状态发生变化时(如设备注册、设备数据上报、设备离线等),开放消息平台通过 Pulsar 主动推送各种事件数据给外部合作伙伴,以满足合作伙伴对消息实时性和消息持久化的要求。
目前涂鸦基于开源的 Pulsar 系统进行了定制改进,提供 Golang 版本 Tuya-Pulsar-SDK-Go。
在 Tuya-Pulsar-Go 获取 SDK 地址。
在 Projects > Get from VCS > URL,输入 SDK 地址,单击 Clone。
在 example > main.go 文件,编辑对应的 PulsarAddr、accessID 和 accessKey 参数。
代码示例如下
// SetInternalLogLevel(logrus.DebugLevel)
tylog.SetGlobalLog("sdk", false)
accessID := "xtu7maff*****8ufo"
accessKey := "479bcba6d******c4e080f7"
topic := pulsar.TopicForAccessID(accessID)
// create client
cfg := pulsar.ClientConfig{
PulsarAddr: pulsar.PulsarAddrCN,
}
c := pulsar.NewClient(cfg)
选中 example > main.go 文件,单击右键,选择 Run ‘go build main.go’ ,执行文件。
执行结果:

GOPATH=/Users/even/Documengts/go #gosetup
