json配置文件支持
功能描述
OpenNJet目前支持json格式的配置文件。
配置说明
一条njet.conf指令的标准json格式如下：
{
"cmd": "worker_processes",
"args": [
"auto"
]
}如果指令包含多个参数，例如add_header Host $host; ，则可以写成：
{
"cmd": "add_header",
"args": [
"Host",
"$host"
]
}配置NJET配置文件中upstream代码块格式：
upstream backend1 {
zone backend1 10m;
server 127.0.0.1:5900 weight=1;
}{
"cmd": "upstream",
"args": [
"backend1"
],
"block": [
{
"cmd": "zone",
"args": [
"backend1",
"10m"
]
},
{
"cmd": "server",
"args": [
"127.0.0.1:5900",
"weight=1"
]
}
]
}配置NJET配置文件中http/stream代码块格式：
http {
dyn_kv_conf conf/iot-work.conf;
include conf/iot-work.conf;
access_log off;
server {
listen 8080;
location / {
root html;
}
}
}{
"cmd": "http",
"args": [],
"block": [
{
"cmd": "dyn_kv_conf",
"args": [
"conf/iot-work.conf"
]
},
{
"cmd": "include",
"args": [
"mime.types"
]
},
{
"cmd": "access_log",
"args": [
"off"
]
},
{
"cmd": "server",
"args": [],
"block": [
{
"cmd": "listen",
"args": [
"8080"
]
},
{
"cmd": "location",
"args": [
"/"
],
"block": [
{
"cmd": "root",
"args": [
"html"
]
}
]
}
]
}
]
}配置NJET配置文件中server代码块格式：
server {
listen 443 ssl;
ssl_certificate certs/rsa.server.cer.pem;
ssl_certificate_key certs/rsa.server.key.pem;
location / {
root html;
}
} {
"cmd": "server",
"args": [],
"block": [
{
"cmd": "listen",
"args": [
"443",
"ssl"
]
},
{
"cmd": "ssl_certificate",
"args": [
"certs/rsa.server.cer.pem"
]
},
{
"cmd": "ssl_certificate_key",
"args": [
"certs/rsa.server.key.pem"
]
}
{
"cmd": "location",
"args": [
"/"
],
"block": [
{
"cmd": "root",
"args": [
"html"
]
}
]
}
]
}配置NJET配置文件中lua代码块格式：
location / {
content_by_lua_block {
njt.sleep(5)
njt.say ("test ok")
}
} {
"cmd": "location",
"args": [
"/"
],
"block": [
{
"cmd": "content_by_lua_block",
"args": [],
"block": [
{
"code": "\n\n njt.sleep(5)\n njt.say(\"test ok\")\n "
}
]
}
]

"file": "/usr/local/njet/conf/njet.conf"JSON格式配置文件使用和检查：
配置好json配置文件后，通过-c命令指定该json即可启动。
示例：
/usr/local/njet/sbin/njet -p /usr/local/njet/ -c conf/njet_conf.json -e logs/error.log验证是否配置成功可以使用-t命令
示例：
/usr/local/njet/sbin/njet -p /usr/local/njet/ -c conf/njet_conf.json -e logs/error.log -t返回值：
njet: the configuration file /usr/local/njet/conf/njet_conf.json syntax is ok
njet: configuration file /usr/local/njet/conf/njet_conf.json test is successful如果语法不正确，则会报错：
njet: [emerg] JSON file parse error (line 9, colume 5): ']' expected near '{'
njet: [emerg] unexpected "{" in /usr/local/njet/conf/njet_conf.json:1
