关于1400的协议资源太匮乏，协议文档写的太碎了，没有GB28181那么完整，有说明有示例；一开始没有相应的设备可以测试协议，一路摸索走了很多弯路，猜测加联想。写篇帖子，和大家相互学习。
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"}}
后续再增加其他协议的说明
