||
"appenders": {
|
||
"out" :{
|
||
"type": "file",
|
||
"options":{
|
||
"file": "gohttpd.log"
|
||
}
|
||
}
|
||
},
|
||
"categories": {
|
||
"default": {
|
||
"appenders": [ "out" ],
|
||
"level": "debug"
|
||
}
|
||
}
|
||
},
|
||
"admin" : {
|
||
"name": "admin",
|
||
"port" : 8088,
|
||
"username": "admin",
|
||
"password": "admin",
|
||
"directives":[
|
||
"Set-Header Access-Control-Allow-Origin *"
|
||
],
|
||
"paths": [
|
||
{
|
||
"path": "/",

||
"default": "index.html"
|
||
}

||
},
|
||
"servers":[{
|
||
"port" : 8080,
|
||
"name":"test",
|
||
"paths":[
|
||
{
|
||
"path": "/",
|
||
"root": "/home/kingecg/code/gohttp/public/",
|
||
"default": "index.html"
|
||
},
|
||
{
|
||
"path": "/ws",
|
||
"upstreams":["http://localhost:3000"],
|
||
"directives":[
|
||
"HostSchemas $target",
|
||
"HeaderOrigin",
|
||
"Path /ws /",
|
||
"RemoveCookie token"
|
||
]
|
||
}
|
||
]
|
||
}]
|
||
}
|
||
```
|
||
- logging 日志配置
|
||
- admin 管理后台配置
|
||
- servers 服务器配置
|
||
|
||
日志采用自己实现的类log4j库,目前只支持console 和file两种appeder
|
||
|
||
servers 配置
|
||
|
||
- port 端口
|
||
- name 服务器名称
|
||
- paths 路径配置
|
||
- certfile 证书文件
|
||
- keyfile 证书密钥文件
|
||
- directives 指令 针对response的指令,目前只实现了set-header
|
||
|
||
|
||
paths 配置
|
||
|
||
- path 路径
|
||
- root 根目录
|
||
- default 默认文件
|
||
- upstreams 代理地址
|
||
- directives 这里指令针对的是代理请求,有以下几种:
|
||
- HostSchemas [$target] 代理地址
|
||
- HeaderOrigin 代理请求时,添加Origin头
|
||
- Path [/ws] [/] 代理请求时,重写URL路径,用第二个参数替换url中的第一个部分
|
||
- RemoveCookie [token] 代理请求时,删除cookie中的某些字段
|
||
|
||
### 指令系统
|
||
|
||
指令系统采用了nginx的指令系统,指令的格式为:
|
||
|
||
```
|
||
指令名 参数1 参数2 ... 参数n
|
||
```
|
||
指令系统用来对特定的request/response进行处理。目前只支持:
|
||
|
||
- 返回的response中设置header
|
||
- 反向代理时,修改发送到上游服务器的请求
|
||
|
||
## Packages
|
||
|
||
### Server
|
||
|
||
RestMux 提供
|
||
- Restful API注册功能的 ServerMux
|
||
- Route
|
||
- Url路径参数解析(形如:/user/:id)
|
||
- 中间件

|
||

||
### handler

|
||
其中proxy handler 提供简单的负载均衡和会话粘滞功能
|

|
