公安视图库1400的协议

一、平台注册/注销

1.1 注册/注销流程

注册流程1如图所示

图 1

下级平台主动向上级平台注册；注册鉴权信息（用户名和密码）由上级平台提供；

1.2 报文说明

1.2.1 下级第一次注册

POST /VIID/System/Register HTTP/1.1

Host: 192.168.1.240:10000

Accept: application/json,application/*+json

Content-Type: application/VIID+JSON;charset=UTF-8

Connection: keepalive

User-Identify:34020000001110000001

User-Agent: libghttp/1.0

Content-Length: 64

{

."RegisterObject":.{

.."DeviceID":."34020000001110000001"

.}

}

其中192.168.1.240:10000为注册平台的地址

 1.2.2 上级响应未认证

HTTP/1.1 401 Unauthorized

Content-Type: application/json

WWW-Authenticate: Digest realm="firberhome", nonce="8qx43l7i"

1.2.3 下级第二次注册

POST /VIID/System/Register HTTP/1.1

Host: 192.168.1.240:10008

Accept: application/json,application/*+json

Content-Type: application/*+JSON;charset=UTF-8

Connection: keepalive

User-Identify:34020000001110000001

Authorization: Digest username="dbTest", realm="firberhome", nonce="8qx43l7i", uri="/VIID/System/Register", algorithm="MD5", cnonce="wenminchen@126.com", nc=00000001, qop=auth, response="48164a9699ccec9345016d62bc27384e"

User-Agent: libghttp/1.0

Content-Length: 64

{

."RegisterObject":.{

.."DeviceID":."34020000001110000001"

.}

}

1.2.4 注册成功上级响应

HTTP/1.1 200 OK

Content-Type: application/json

{"ResponseStatus":{"Id":"34020000001110000001","LocalTime":"20200512161231","RequestURL":"/VIID/System/Register","StatusCode":0,"StatusString":"OK"}}

以上为完整的注册流程，注销流程类似

二、Keepalived保活

2.1保活流程

下级向上级上报心跳数据

2.2 报文说明

2.2.1 下级上报保活

POST /VIID/System/Keepalive HTTP/1.1

Host: 192.168.1.240:10000

Accept: application/json,application/*+json

Content-Type: application/VIID+JSON;charset=UTF-8

Connection: keepalive

User-Identify:34020000001110000001

User-Agent: libghttp/1.0

Content-Length: 65

{

."KeepaliveObject":.{

.."DeviceID":."34020000001110000001"

.}

}

4.2.2 上级反馈响应

HTTP/1.1 200 OK

Content-Type: application/json

{"ResponseStatus":{"Id":"34020000001110000001","LocalTime":"20200512161231","RequestURL":"/VIID/System/Keepalive","StatusCode":0,"StatusString":"OK"}}

订阅-通知

上下级概念

订阅通知过程本质是数据转移，例如A想通过视图库获得B的机动车数据，那么A就是上级、B就是下级；假如A想通过B间接获得C的机动车数据，那么A就是B的上级，B是C的上级，这个过程为跨级订阅/通知。

 

tep1：订阅者（上级）向被订阅者（下级）发送HTTP POST请求/VIID/Subscribes。

Step2：被订阅者（下级）将订阅成功与否的响应消息返回给订阅者（上级）。

订阅成功后，被订阅者（下级）如果有订阅信息，便会进行通知任务。

Step3：被订阅者（下级）向订阅者（上级）发送HTTP POST请求/VIID/SubscribeNotifications。

Step4：订阅者（上级）返回响应消息。

Step5：被订阅者（下级）接收到Step4订阅者（上级）正确返回结果才会再重复Step3，4的操作，如此循环。
