在OpenWrt/LEDE系统中处理JSON的方法，这里记录一下。
假设有一个JSON文件
cat /etc/ss.json
{
"server": "8.8.8.8",
"server_port": 443,
"local_address": "0.0.0.0",
"local_port": 7070,
"password": "fuckgfang",
"method": "aes_128_ctr",
"timeout": "60",
"protocol": "auth_aes128_sha1",
"fast_open": false
}
处理方式1
$ jsonfilter -i /etc/ss.json -e "@.server"
8.8.8.8
$ CONF=/etc/ss.json
$ a=$(jsonfilter -i $CONF -e "@.server")
$ echo $a
8.8.8.8
