Filecoin RPC 接口之获取最新块信息 - 简单教程，简单编程

Filecoin RPC 接口之获取最新块信息，调用的 RPC 方法名是 Filecoin.ChainHead

Curl 发起的请求为

curl -X POST \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer $(cat ~/.lotusstorage/token)" \
     --data '{"jsonrpc": "2.0", "method": "Filecoin.ChainHead", "params": [], "id": 1}' \
     'http://127.0.0.1:1234/rpc/v0'

返回的信息如下
