关键技术

curl发送带有变量的json

function upload() {
curl -X POST -H "Accept: application/json" -H "Content-Type: application/json" http://127.0.0.1:1988/v1/push -vv --data @<(cat <<EOF
[{
"metric": "$name", "endpoint": "$endpoint", "timestamp": $timenow, "step": 60,"value": "$value", "counterType": "$type", "tags": ""
}]
EOF
)
}
