1 Server-proxy 数据交换协议

概述

Server-proxy 数据交换基于JSON格式。

请求和响应消息必须以header and data length开头

被动代理

代理配置请求

proxy config 请求由服务器发送以提供代理配置数据。每次发送此请求 ProxyConfigFrequency （服务器配置参数）秒。

name				value type	description
server→proxy:
request				string	‘proxy config’
<table>				object	one or more objects with <table> data
	fields			array	array of field names
		-		string	field name
	data			array	array of rows
		-		array	array of columns
			-	string,number	column value with type depending on column type in database schema
proxy→server:
response				string	the request success information (‘success’ or ‘failed’)
version				string	the proxy version (<major>.<minor>.<build>)

例：

server→proxy:

{
           "request": "proxy config",
           "globalmacro":{

向后兼容性

服务器通过接受旧的支持部分向后兼容 host availability, history data, discovery data and auto registration 请求.

1 Server-proxy data exchange protocol

Overview

Server - proxy data exchange is based on JSON format.

Request and response messages must begin with header and data length.

Passive proxy

Proxy config request

The proxy config request is sent by server to provide proxy configuration data. This request is sent every ProxyConfigFrequency (server configuration parameter) seconds.

name				value type	description
server→proxy:
request				string	‘proxy config’
<table>				object	one or more objects with <table> data
	fields			array	array of field names
		-		string	field name
	data			array	array of rows
		-		array	array of columns
			-	string,number	column value with type depending on column type in database schema
proxy→server:
response				string	the request success information (‘success’ or ‘failed’)
version				string	the proxy version (<major>.<minor>.<build>)

Example:

server→proxy:

{
           "request": "proxy config",
           "globalmacro":{
