## Configuration file content
ahserver using json file format in its configuration, the following is a sample:
```
{
"databases":{
"aiocfae":{
"driver":"aiomysql",
"async_mode":true,
"coding":"utf8",
"dbname":"cfae",
"kwargs":{
"user":"test",
"db":"cfae",
"password":"test123",
"host":"localhost"
}
},
"cfae":{
"driver":"mysql.connector",
"coding":"utf8",
"dbname":"cfae",
"kwargs":{
"user":"test",
"db":"cfae",
"password":"test123",
"host":"localhost"
}
}
},
"website":{
"paths":[
["$[workdir]$/../usedpkgs/antd","/antd"],
["$[workdir]$/../wolon",""]
],
"host":"0.0.0.0",
"port":8080,
"coding":"utf-8",
"ssl":{
"crtfile":"$[workdir]$/conf/www.xxx.com.pem",
"keyfile":"$[workdir]$/conf/www.xxx.com.key"
},
"indexes":[
"index.html",
"index.tmpl",
"index.dspy",
"index.md"
],
"visualcoding":{
"default_root":"/samples/vc/test",

]
},
"langMapping":{
"zh-Hans-CN":"zh-cn",
"zh-CN":"zh-cn",

}
}
```
### database configuration
the ahserver using packages for database engines are:
* oracle:cx_Oracle
* mysql:mysql-connector
* postgresql:psycopg2
* sql server:pymssql
however, you can change it, but must change the "driver" value the the package name in the database connection definition.
in the databases section in config.json, you can define one or more database connection, and also, it support many database engine, just as ORACLE,mysql,postgreSQL.
define a database connnect you need follow the following json format.
* mysql or mariadb
```
"metadb":{
"driver":"mysql.connector",
"coding":"utf8",
"dbname":"sampledb",
"kwargs":{
"user":"user1",
"db":"sampledb",
"password":"user123",
"host":"localhost"
}
}
```
the dbname and "db" should the same, which is the database name in mysql database
* Oracle
```
"db_ora":{
"driver":"cx_Oracle",
"coding":"utf8",
"dbname":sampledb",
"kwargs":{
"user":"user1",
"host":"localhost",
"dsn":"10.0.185.137:1521/SAMPLEDB"
}
}
```
* SQL Server
```
"db_mssql":{
"driver":"pymssql",
"coding":"utf8",
"dbname":"sampledb",
"kwargs":{
"user":"user1",
"database":"sampledb",
"password":"user123",
"server":"localhost",
"port":1433,
"charset":"utf8"
}
}
```
* PostgreSQL
```
"db_pg":{
"driver":"psycopg2",
"dbname":"testdb",
"coding":"utf8",
"kwargs":{
"database":"testdb",
"user":"postgres",
"password":"pass123",
"host":"127.0.0.1",
"port":"5432"
}
}
```
### https support
In config.json file, config.website.ssl need to set(see above)
### website configuration
#### paths
ahserver can serve its contents (static file, dynamic contents render by its processors) resided on difference folders on the server file system.
ahserver finds a content identified by http url in order the of the paths specified by "paths" lists inside "website" definition of config.json file
#### processors
all the prcessors ahserver using, must be listed here.
#### host
by defaualt, '0.0.0.0'
#### port
by default, 8080
#### coding
ahserver recomments using 'utf-8'
### langMapping
the browsers will send 'Accept-Language' are difference even if the same language. so ahserver using a "langMapping" definition to mapping multiple browser lang to same i18n file
## international
ahserver using MiniI18N in appPublic modules in pyutils package to implements i18n support
it will search translate text in ms* txt file in folder named by language name inside i18n folder in workdir folder, workdir is the folder where the ahserver program resided or identified by command line paraments.
## performance
To be list here
## Behind the nginx
when ahserver running behind the nginx, nginx should be forward following header to ahserver
* X-Forwarded-For: client real ip
* X-Forwarded-Scheme: scheme in client browser
* X-Forwarded-Host: host in client browser
* X-Forwarded-Url: url in client browser
## environment for processors
When coding in processors, ahserver provide some environment stuff for build apllication, there are modules, functions, classes and variables
