当钱已发送到本地 regtest 网络上的特定比特币地址时，我如何收到通知？
How can I get notified when money has been sent to a particular Bitcoin address on a local regtest network?
我想以编程方式检测何时有人将比特币发送到某个地址。这发生在我开始使用这个 docker-compose.yml 文件的本地测试网上。
一旦本地测试网 运行s，我使用
创建一个新地址
docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli getnewaddress
说吧returns2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181.
我把这个地址放到下面Java code:
import org.bitcoinj.core.Address;
import org.bitcoinj.core.Coin;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.core.Transaction;
import org.bitcoinj.wallet.Wallet;
import org.bitcoinj.wallet.listeners.WalletCoinsReceivedEventListener;
public class WalletObserver {
public void init() {
final NetworkParameters netParams = NetworkParameters.fromID(NetworkParameters.ID_REGTEST);
try {
final Wallet wallet = Wallet.createBasic(netParams);
wallet.addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
wallet.addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
@Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
}
然后我用 class.
启动 Java 应用程序
然后我发送一些测试比特币到有问题的地址：
% docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.5
068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406
如果我去 http://localhost:3002/tx/068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406，我会看到交易详情。
然而，侦听器中的断点（onCoinsReceived 方法）永远不会激活。
我需要如何修改我的代码 and/or 我用来发送测试 BTC 的命令，以便每当该帐户收到钱时，都会调用 onCoinsReceived 方法？ 有什么地方可以告诉 Wallet 或 NetworkParameters 我想连接到本地主机吗？
我使用的是 bitcoinj-core 0.15.10 版。
更新 1：
我修改了 docker-compose.yml 并添加了以下端口映射：
ports:
- "51001:50001"
- "51002:50002"
- "19001:19001"
- "19000:19000"
- "28332:28332"
然后我重写了init方法，这样我就可以连接到localhost并指定端口：
public class WalletObserver {
public void init() {
final LocalTestNetParams netParams = new LocalTestNetParams();
netParams.setPort(50001);
try {
final WalletAppKit kit = new WalletAppKit(netParams, new File("."), "_minimalCryptoExchangeBtcWallet");
kit.setAutoSave(true);
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning(); // I never get past this point
kit.peerGroup().addPeerDiscovery(new DnsDiscovery(netParams));
kit.wallet().addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
@Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
LocalTestNetParams允许指定端口：
package com.dpisarenko.minimalcryptoexchange.logic.btc;
import org.bitcoinj.params.RegTestParams;
public class LocalTestNetParams extends RegTestParams {
public void setPort(final int newPort) {
this.port = newPort;
}
}
我在 netParams.setPort(50001); 中尝试了上述所有端口。
在所有情况下，我都会在 kit.awaitRunning(); 之后收到以下消息：

更新 1：
我尝试使用 network_mode: "host"。
如果我将它添加到 node，如
node:
image: ulamlabs/bitcoind-custom-regtest:latest
network_mode: "host"
当我 运行 docker-compose up -d:
时出现以下错误

更新二：
如果我注释掉
中的端口绑定
electrumx:

# - "28332:28332"
和运行 docker-compose up -d我得到

更新 3： 我假设错误的根源是在我的 Java 代码中我尝试连接到 ElectrumX 服务器而不是实际的比特币节点（node 在 docker-compose.yml）。
更新 4：
我改docker-compose.yml如下：
node:
image: ulamlabs/bitcoind-custom-regtest:latest
# For ports used by node see
# https://github.com/ulamlabs/bitcoind-custom-regtest/blob/master/bitcoin.conf
ports:

现在我收到不同的错误（完整日志可用 here）：

更新 5：
有人建议（在现已删除的评论中）在应用程序的输出中有这条 Peer does not support bloom filtering 消息：

所以我尝试分叉原始图像并更改 bitcoin.conf 文件以启用 Bloom 过滤：
peerbloomfilters=1
当我运行 docker build -t mentiflectax/bitcoind-custom-regtest:latest .时，我得到以下错误信息（剩余输出的一部分可以找到here）：

更新6：正确的端口好像是19000.
如果我使用端口 19001，在 kit.awaitRunning() 之后会出现以下错误：
INFO org.bitcoinj.core.PeerSocketHandler - [127.0.0.1]:19001: Timed out
完整的日志输出可用here。
我还没有用 electrumx 和 ethereum 文件中存在的 ethereum 东西测试你的完整设置，但关于你的问题，以下步骤工作正常，我认为它在您的完整设置中也能发挥作用。
我 运行 和 docker 一个基于你提供的 ulamlabs/bitcoind-custom-regtest:latest 图片的比特币节点：
docker run -p 18444:19000 -d ulamlabs/bitcoind-custom-regtest:latest
如您所见，我将图像内部端口 19000 公开为 RegTestParams、18444 的 default port。从我们客户的角度来看，有了这个设置，基本上它看起来就像我们是 运行 主机中的比特币守护进程。使用您的 LocalTestNetParams class 并按照您的指示提供端口 19000 也应该可以解决问题。
然后，根据您在问题中提供的反馈，我使用bash和vi手动编辑了/root/.bitcoin/bitcoin.conf中比特币节点的守护程序配置：
docker exec -it 0aa2e863cd9927 bash
并包含以下配置：
peerbloomfilters=1
重启容器后，我得到了一个新地址：
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest getnewaddress
假设新地址是您在问题中提供的地址：
2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181
然后，按照 Bitcoin documentation 中的建议，为了避免资金不足错误，我生成了 101 个区块到这个地址：
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest generatetoaddress 101 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181
我使用了 generatetoaddress 而不是 generate 因为 since Bitcoin 0.19.0 the option is no longer valid.
接下来，我根据您提供的信息和 Bitcoinj 库文档中的 this example 准备了一个简单的 Java 程序：
import java.io.File;
import org.bitcoinj.core.Address;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.kits.WalletAppKit;
import org.bitcoinj.params.RegTestParams;
public class Kit {
public static void main(String[] args) {
Kit kit = new Kit();
kit.run();
}
private synchronized void run(){
NetworkParameters params = RegTestParams.get();
WalletAppKit kit = new WalletAppKit(params, new File("."), "walletappkit-example");
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning();
kit.wallet().addWatchedAddress(Address.fromString(params, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener((wallet, tx, prevBalance, newBalance) -> {
System.out.println("-----> coins resceived: " + tx.getTxId());
});
while (true) {
try {
this.wait(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
我用了一个简单的while循环来保持问题运行；当然，如果在实际设置中可能是不必要的，因为您似乎正在使用 Spring Boot.
然后，如果你发送一些比特币到这个地址：
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.00001
0f972642713c72ae0fe03fe51818b9ea4d483720b69b90e795f35eb80a587c26

还有一个你提到的问题我没有机会测试，它正在创建一个新的Docker图像，其中peerbloomfilters配置将被正确配置而不需要修改实际的容器状态。我认为您指出的编译问题可能与 this issue 有关，基本上，容器没有足够的资源来执行该过程。如果您使用 macOS 并且 Docker 用于 Mac，请尝试调整容器可用的内存量，这可能会有所帮助。所用基础 alpine 图像的变化也可以激发问题。我也会尝试深入研究这个问题。
我想以编程方式检测何时有人将比特币发送到某个地址。这发生在我开始使用这个 docker-compose.yml 文件的本地测试网上。
一旦本地测试网 运行s，我使用
创建一个新地址docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli getnewaddress
说吧returns2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181.
我把这个地址放到下面Java code:
import org.bitcoinj.core.Address;
import org.bitcoinj.core.Coin;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.core.Transaction;
import org.bitcoinj.wallet.Wallet;
import org.bitcoinj.wallet.listeners.WalletCoinsReceivedEventListener;
public class WalletObserver {
public void init() {
final NetworkParameters netParams = NetworkParameters.fromID(NetworkParameters.ID_REGTEST);
try {
final Wallet wallet = Wallet.createBasic(netParams);
wallet.addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
wallet.addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
@Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
}
然后我用 class.
启动 Java 应用程序然后我发送一些测试比特币到有问题的地址：
% docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.5
068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406
如果我去 http://localhost:3002/tx/068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406，我会看到交易详情。
然而，侦听器中的断点（onCoinsReceived 方法）永远不会激活。
我需要如何修改我的代码 and/or 我用来发送测试 BTC 的命令，以便每当该帐户收到钱时，都会调用 onCoinsReceived 方法？ 有什么地方可以告诉 Wallet 或 NetworkParameters 我想连接到本地主机吗？
我使用的是 bitcoinj-core 0.15.10 版。
更新 1：
我修改了 docker-compose.yml 并添加了以下端口映射：
ports:
- "51001:50001"
- "51002:50002"
- "19001:19001"
- "19000:19000"
- "28332:28332"
然后我重写了init方法，这样我就可以连接到localhost并指定端口：
public class WalletObserver {
public void init() {
final LocalTestNetParams netParams = new LocalTestNetParams();
netParams.setPort(50001);
try {
final WalletAppKit kit = new WalletAppKit(netParams, new File("."), "_minimalCryptoExchangeBtcWallet");
kit.setAutoSave(true);
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning(); // I never get past this point
kit.peerGroup().addPeerDiscovery(new DnsDiscovery(netParams));
kit.wallet().addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
@Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
LocalTestNetParams允许指定端口：
package com.dpisarenko.minimalcryptoexchange.logic.btc;
import org.bitcoinj.params.RegTestParams;
public class LocalTestNetParams extends RegTestParams {
public void setPort(final int newPort) {
this.port = newPort;
}
}
我在 netParams.setPort(50001); 中尝试了上述所有端口。
在所有情况下，我都会在 kit.awaitRunning(); 之后收到以下消息：

更新 1：
我尝试使用 network_mode: "host"。
如果我将它添加到 node，如
node:
image: ulamlabs/bitcoind-custom-regtest:latest
network_mode: "host"

更新二：
如果我注释掉
中的端口绑定 electrumx:

更新 3： 我假设错误的根源是在我的 Java 代码中我尝试连接到 ElectrumX 服务器而不是实际的比特币节点（node 在 docker-compose.yml）。
更新 4：
我改docker-compose.yml如下：
node:

# For ports used by node see
# https://github.com/ulamlabs/bitcoind-custom-regtest/blob/master/bitcoin.conf

更新 5：
有人建议（在现已删除的评论中）在应用程序的输出中有这条 Peer does not support bloom filtering 消息：
11:32:43.482 [NioClientManager] INFO org.bitcoinj.core.Peer - Peer{[127.0.0.1]:19000, version=70015, subVer=/Satoshi:0.19.1(bitcore)/, services=1033 (NETWORK, WITNESS, NETWORK_LIMITED), time=2021-11-06 11:32:43, height=4}: Peer does not support bloom filtering.
所以我尝试分叉原始图像并更改 bitcoin.conf 文件以启用 Bloom 过滤：
peerbloomfilters=1
当我运行 docker build -t mentiflectax/bitcoind-custom-regtest:latest .时，我得到以下错误信息（剩余输出的一部分可以找到here）：

更新6：正确的端口好像是19000.
如果我使用端口 19001，在 kit.awaitRunning() 之后会出现以下错误：
INFO org.bitcoinj.core.PeerSocketHandler - [127.0.0.1]:19001: Timed out
完整的日志输出可用here。
我还没有用 electrumx 和 ethereum 文件中存在的 ethereum 东西测试你的完整设置，但关于你的问题，以下步骤工作正常，我认为它在您的完整设置中也能发挥作用。
我 运行 和 docker 一个基于你提供的 ulamlabs/bitcoind-custom-regtest:latest 图片的比特币节点：
docker run -p 18444:19000 -d ulamlabs/bitcoind-custom-regtest:latest
如您所见，我将图像内部端口 19000 公开为 RegTestParams、18444 的 default port。从我们客户的角度来看，有了这个设置，基本上它看起来就像我们是 运行 主机中的比特币守护进程。使用您的 LocalTestNetParams class 并按照您的指示提供端口 19000 也应该可以解决问题。
然后，根据您在问题中提供的反馈，我使用bash和vi手动编辑了/root/.bitcoin/bitcoin.conf中比特币节点的守护程序配置：
docker exec -it 0aa2e863cd9927 bash
并包含以下配置：
peerbloomfilters=1
重启容器后，我得到了一个新地址：
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest getnewaddress
假设新地址是您在问题中提供的地址：
2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181
然后，按照 Bitcoin documentation 中的建议，为了避免资金不足错误，我生成了 101 个区块到这个地址：
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest generatetoaddress 101 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181
我使用了 generatetoaddress 而不是 generate 因为 since Bitcoin 0.19.0 the option is no longer valid.
接下来，我根据您提供的信息和 Bitcoinj 库文档中的 this example 准备了一个简单的 Java 程序：
import java.io.File;
import org.bitcoinj.core.Address;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.kits.WalletAppKit;
import org.bitcoinj.params.RegTestParams;
public class Kit {
public static void main(String[] args) {
Kit kit = new Kit();
kit.run();
}
private synchronized void run(){
NetworkParameters params = RegTestParams.get();
WalletAppKit kit = new WalletAppKit(params, new File("."), "walletappkit-example");
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning();
kit.wallet().addWatchedAddress(Address.fromString(params, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener((wallet, tx, prevBalance, newBalance) -> {
System.out.println("-----> coins resceived: " + tx.getTxId());
});
while (true) {
try {
this.wait(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
我用了一个简单的while循环来保持问题运行；当然，如果在实际设置中可能是不必要的，因为您似乎正在使用 Spring Boot.
然后，如果你发送一些比特币到这个地址：
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.00001
0f972642713c72ae0fe03fe51818b9ea4d483720b69b90e795f35eb80a587c26

还有一个你提到的问题我没有机会测试，它正在创建一个新的Docker图像，其中peerbloomfilters配置将被正确配置而不需要修改实际的容器状态。我认为您指出的编译问题可能与 this issue 有关，基本上，容器没有足够的资源来执行该过程。如果您使用 macOS 并且 Docker 用于 Mac，请尝试调整容器可用的内存量，这可能会有所帮助。所用基础 alpine 图像的变化也可以激发问题。我也会尝试深入研究这个问题。
