mac搭建比特币开发环境
0 曾尝试源码自行编译，无奈各种error，官网有已经编译好的；
1 下载后解压即可，bin文件下面有我们想要的；
2 启动测试网络，-daemon表示后台运行，想看实时的信息就不需要加这个,信息打印了默认data的路径；
rpc的接口文档
不一定都是最新的，如果有问题，命令行执行时会有相关提示；
2.1 配置文件
默认会在当前目录下查找配置bitcoin.conf，自行创建主要配置项如下，具体含义可以查询帮助文档；
regtest=1
rpcbind=127.0.0.1
rpcuser=test
rpcpassword=test
server=1
daemon=1
txindex=1
然后启动
./bitcoind
Default data directory /Users/zhouyc/Library/Application Support/Bitcoin
2019-04-16T02:39:27Z Using data directory /Users/zhouyc/Library/Application Support/Bitcoin/regtest
2019-04-16T02:39:27Z Using config file /Users/zhouyc/Library/Application Support/Bitcoin/bitcoin.conf
启动命令行进行挖矿，100个确认之后才能使用，官网有说明
./bitcoin-cli -regtest generate 101
3 查看余额
./bitcoin-cli -regtest getbalance
50.00000000
4 默认的账户是哪个？
是""
5 查看账户listaccounts
这个接口已经废弃，有提示显示如下：
listaccounts is deprecated and will be removed in V0.18. To use this command, start bitcoind with -deprecatedrpc=accounts.
bitcoin-cli -regtest listaccounts
{
"": 50.00000000
}
bitcoin-cli -regtest getaccountaddress ""
#regtest网络的地址以2开头？

6 产生一个新地址
regtest类型的地址，跟mainnet的不一样，如果需要模拟mainnet的，需要修改源码，自行编译，具体哪一块我还没研究 :)
./bitcoin-cli -regtest getnewaddress "test"
2N2qPWWUtxnevHf9Db56CYjnZG5zwotUeLx
7 给指定账户产出btc
The generatetoaddress RPC mines blocks immediately to a specified address.
挖2个block
./bitcoin-cli -regtest generatetoaddress 2 "2N2qPWWUtxnevHf9Db56CYjnZG5zwotUeLx" 500
[
"326941b8ce74e9d98223155cff58b2842612c1ff893e2f38b47f4959067a46ea",
"188641b5dd72512482af2ed9aa625dbb46d4564afb5fef777697ee8e79f27f1a"
]
查看指定账户余额,1表示至少1个确认即可，true？
bitcoin-cli -regtest getbalance "test" 1 true
100.00000000
8 脚本挖矿
因为regtest模式不会自动挖矿，需要自己执行命令，可以尝试通过脚本执行
$ while true; do bitcoin-cli -regtest generate 1; sleep 300; done
9 发送比特币
bitcoin-cli -regtest sendtoaddress 2N2qPWWUtxnevHf9Db56CYjnZG5zwotUeLx 1 "sendtoaddress example" "Nemo From Example.com"
827fd8abb52185522bb6937adbda60c22228712816187a39b3f8230ec396ac4f
查看交易信息,确认数0，需要手动产生一些新的区块
bitcoin-cli -regtest gettransaction 827fd8abb52185522bb6937adbda60c22228712816187a39b3f8230ec396ac4f

10 如何通过http的方式发起请求？
使用帮助命令，会给出用例
Examples:
bitcoin-cli getblockchaininfo
curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
11 默认端口
通过查询进程与端口号
ps -ef|grep bitcoind
501 1854 93800 0 5:08PM ttys011 0:00.26 ./bitcoind
lsof -p 1854|grep LISTEN
bitcoind 1854 zhouyc 10u IPv6 0x10f9fba835ac81ff 0t0 TCP localhost:18443 (LISTEN)

bitcoind 1854 zhouyc 31u IPv6 0x10f9fba835ac53ff 0t0 TCP *:18444 (LISTEN)

curl --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' http://test:test@127.0.0.1:18443/
