配置文件

Mac 系统下 默认配置文件文件在 ~/Library/Application\ Support/Bitcoin

放在 /mnt/bitcoin 目录下

# /mnt/bitcoin/bitcoin.conf 

server=1
daemon=1
rpcallowip=127.0.0.1/0 #局域网访问
rpcthreads=10
txindex=1
rpcuser=user #用户
rpcpassword=pass #密码

[regtest] #从 0.17.0开始，在一个配置文件中设置不同的启动模式
rpcport=18443
deprecatedrpc=signrawtransaction # 从 0.17.0版本signrawtransaction 要被弃用

运行节点

bitcoind -datadir=/mnt/bitcoin # 确保有/mnt/bitcoin/bitcoin.conf

# 运行regtest模式，即私链模式
bitcoind -regtest -datadir=/mnt/bitcoin

# 私链持续挖矿
while true; do bitcoin-cli -regtest -datadir=/mnt/bitcoin generate 1; sleep 1; done

curl getblockhash

如果没有配置 rpcuser、 rpcpassword，curl 不会返回数据

curl -X POST http://127.0.0.1:8332/ -u user:pass -H 'content-type:text/plain;'  \
-d '{"jsonrpc":"1.0","id":"1","method":"getblockhash","params":[0]}'

{
  "result": "00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048",
  "error": null,
  "id": "1"
}

curl getblockcount

curl -X POST http://127.0.0.1:8332/ -u user:pass -H 'content-type:text/plain;' \
-d '{"jsonrpc":"2.0","id":"1","method":"getblockcount","params":[]}'

{
    "result":238667,
    "error":null,
    "id":"1"
}

python script

import json
import requests

url = "http://127.0.0.1:8332/"
auth=("user", "pass")
payload = json.dumps({"method": 'getblockhash', "params": [1] })

response = requests.request("POST", url, data=payload, auth=auth)
print(response.text)
