长连接服务

更新时间:2018-09-10 15:38:18

提供基于用户维度的长连接通道服务,包括连接通道的绑定、解绑和消息接收。通过长连接服务客户端可以轻松的实现设备实时变更消息的接收。

用户中心长连接

绑定mqtt消息通道

上行,绑定 iotToken对应的用户 和 clientId指定的mqtt通道。

TOPIC: /sys/${productKey}/${deviceName}/app/up/account/bind
REPLY TOPIC:/sys/${productKey}/${deviceName}/app/down/account/bind_reply

request:
{
  "id": "msgid1",
  "version": "1.0",
  "request": {
    "clientId": "mqttusername1234"
  },
  "params": {
    "iotToken": "iot_token123"
  }
}

response:
{
    "id":"msgid1",
    "code":200,
    "message":"success"
}

注意: 通常情况下,开发者不需要主动调用这个接口,长连接 SDK 中已经封装了本接口的实现,请参见:长连接通道与账号绑定 for iOS长连接通道与账号绑定 for Android

解绑mqtt消息通道

上行,解绑 clientId指定的mqtt通道 及此通道对应的用户。

TOPIC: /sys/${productKey}/${deviceName}/app/up/account/unbind
REPLY TOPIC:/sys/${productKey}/${deviceName}/app/down/account/unbind_reply

request:
{
  "id": "msgid2",
  "version": "1.0",
  "request": {
    "clientId": "mqttusername1234"
  },
  "params": {
  }
}

response:
{
    "id":"msgid2",
    "code":200,
    "message":"success"
}

注意: 通常情况下,开发者不需要主动调用这个接口,长连接 SDK 中已经封装了本接口的实现,请参见:取消长连接通道与账号关联 for iOS取消长连接通道与账号关联 for Android

设备消息下行到APP

mqtt消息。
