How can I create dashboad using json file through grafana http API?

Grafana Dashboards
1

Here’s what I need：
I want to create dashboad using json file through grafana http API. The command is below, but I get errors.
# curl -X POST -H “Content-Type: application/json” -d @/work/test.json “http://admin:admin@10.10.10.10:9999/api/dashboards/db”
[{“fieldNames”:[“Dashboard”],“classification”:“RequiredError”,“message”:“Required”}]
json file can be accesed in the website: http://starrocks-thirdparty.oss-cn-zhangjiakou.aliyuncs.com/StarRocks-Overview-24.json

However, I can create dashboard through importing json file.
