开发环境和工具
1. window 10 64
2. 比特核心钱包:bitcoin core 64
配置过程
1. 下载比特币核心钱包,下载链接https://bitcoin.org/en/download
2. 安装完不要运行。启动测试网络,这个需要下的数据比较少,大概10G。如图,第二个启动项
3. 启动后会弹出如图页面:
选择数据存放的位置(正式环境需要100G,随着时间而增加),这个地址下面还需要使用,请记住。
4. 同步数据,如下图所示
下边进度条消失就是同步完了。
5. 配置rpc。在数据存放位置新建一个文件名称是bitcoin.conf,内容如下
testnet=0
server=1
rpcuser=wang
rpcpassword=123456
rpctimeout=30
rpcport=18332
rpcconnect=127.0.0.1
testnet=0是测试网络,正式环境去掉这一行,并把rpcport=18332改为rpcport=8332
6. 代码使用了jsonrpc4j,maven依赖如下
<dependency>
<groupId>com.github.briandilley.jsonrpc4j</groupId>
<artifactId>jsonrpc4j</artifactId>
<version>1.1</version>
</dependency>
6.1. 简单公用类
public class ClientUtil { public static JsonRpcHttpClient getClient() {
JsonRpcHttpClient client = null;
try {
String cred = Base64.encodeBytes(("wang" + ":" +"123456").getBytes());
Map<String, String> headers = new HashMap<String, String>(1);
//身份认证
headers.put("Authorization", "Basic " + cred);
client = new JsonRpcHttpClient(new URL("http://127.0.0.1:18332"),headers);
} catch (MalformedURLException e) {
e.printStackTrace();
}
return client;
} public static Object result(String command, Object[] objects) {
JsonRpcHttpClient client = ClientUtil.getClient();
Object result = null;
if(client != null) {
try {
result = client.invoke(command, objects,Object.class);
} catch (Throwable throwable) {
throwable.printStackTrace();
}
}
return result;
}
}
6.2. 发送比特币
@Test
public void sendfrom() {
String result = (String) ClientUtil.result("sendfrom", new Object[]{"","2MzFix1Fnndi1wAvg9B7dLfRgL25FuC4J7x","0.0001"});
System.out.println(result);
}
第二个参数是对方的地址,第三个参数是金额。
6.3. 生成一个地址,并监测对方是否发送
/**
* 生成一个收款地址,等待接收
*/
@Test
public void newAddressAndReceived() {
String result = (String) ClientUtil.result("getnewaddress", new Object[]{""});
System.out.println(result); while (true) {
Double received = (Double) ClientUtil.result("getreceivedbyaddress", new Object[] {result});
if(received > 0) {
System.out.println(received);
break;
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
