tmp.json:
{
"ip": "127.0.0.1",
"containers": [{
"container_name": "xremote_server_pc_003",
"signaling_port": 51111,
"relay_port": 51112
},
{
"container_name": "xremote_server_pc_005",
"signaling_port": 51121,
"relay_port": 51122
}
]
}
1 获得某个字段值
获得 Ip 字段:
ip=$(jq ".ip" conf.json)
echo "ip: $ip"
结果:
ip: "127.0.0.1"
2 解析数组
解析 containers 数组:
containers=$(jq ".containers" conf.json)
for row in $(echo "${containers}" | jq -r ".[] | @base64")
do
_jq() {
echo ${row} | base64 --decode | jq -r ${1}
}
echo "container_name: $(_jq ".container_name")"
echo "signaling_port: $(_jq ".signaling_port")"
echo "relay_port: $(_jq ".relay_port")"
done
结果:
container_name: xremote_server_pc_003
signaling_port: 51111
relay_port: 51112
container_name: xremote_server_pc_005
signaling_port: 51121
relay_port: 51122
