参考：https://github.com/ethereum/wiki/wiki/JSON-RPC#the-default-block-parameter

The following methods have an extra default block parameter:

• eth_getBalance
• eth_getCode
• eth_getTransactionCount
• eth_getStorageAt
• eth_call

When requests are made that act on the state of ethereum, the last default block parameter determines the height of the block.

The following options are possible for the defaultBlock parameter:

• HEX String - an integer block number
• String "earliest" for the earliest/genesis block
• String "latest" - for the latest mined block
• String "pending" - for the pending state/transactions

 

15.eth_getStorageAt   返回给定地址的存储位置的值

curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getStorageAt","params":["0x2216bbda225f67fed72b416329a29664535104d9","0x0","latest"],"id":64}' 39.107.236.48:8545

 

16.eth_getTransactionCount   返回从地址发送的交易数量
