如果需要一些老接口

1

bitcoind --conf=/opt/bitcoin/blockdata/bitcoin.conf --datadir=/opt/bitcoin/blockdata/ --deprecatedrpc=signrawtransaction

C-lightning && lightning-charge

https://github.com/btcme/lightning-charge

部署

lightning-charge最好用docker直接集成c-lightning一把启动，比如我已经运行了一个bitcoin core全节点，可以直接下面的命令启动:

1
2
3
4
5

docker run -d -u `id -u` -v `pwd`/data:/data -p 9735:9735 -p 9112:9112 \
             -e API_TOKEN=mySecretToken \
             -e NETWORK=testnet  \
             -e BITCOIND_URI="http://user:password@172.18.0.1:18332" \
             shesek/lightning-charge

注意BITCOIND_URL的IP是docker容器内向外连接的，如果不是用net的方式启动，要填docker的网桥地址；

  • 查询运行状况
1

curl http://api-token:mySecretToken@localhost:9112/info
