提问by Jérémie Zarca
I'm trying to get the value of a json array but I don't manage to get the value of a leaf, can anyone help me?

Here's the json from maps.googleapis.com/maps/api
这是来自maps.googleapis.com/maps/api的 json
I'd like to get the duration text and value and here's the script I've been using so far.
我想获取持续时间文本和值，这是我迄今为止一直在使用的脚本。
function jsonValue() {
KEY=
num=
awk -F"[,:}]" '{for(i=1;i<=NF;i++){if($i~/'$KEY'2/){print $(i+1)}}}' | tr -d '"' | sed -n ${num}p
}
curl --get --include 'http://maps.googleapis.com/maps/api/directions/json?origin=59.94473,30.294254&destination=59.80612,30.308552&sensor=false&departure_time=1346197500&mode=transit&format=json' | jsonValue duration["value"] 2
