Java比特幣開發教程:Java編程買賣比特幣

msup / 2486人閱讀

摘要:完整的步驟如下檢查比特幣或的余額,錢包地址。比特幣的到帳時間是個塊的高度,約分鐘。

方案一: 通過ExinCore API進行幣幣交易

Exincore 提供了基于Mixin Network的幣幣交易API.

你可以支付USDT給ExinCore, ExinCore會以最低的價格,最優惠的交易費將你購買的比特幣轉給你, 每一幣交易都是匿名的,并且可以在鏈上進行驗證,交易的細節只有你與ExinCore知道!

ExinCore 也不知道你是誰,它只知道你的UUID.

預備知識:

你先需要創建一個機器人, 方法在 教程一.

安裝依賴包

正如教程一里我們介紹過的, 我們需要依賴 mixin-java-sdk, 你應該先安裝過它了, 這兒我們再安裝其它的軟件包.
下載地址: mvnrepository
build.gradle.kts的dependencies,加入如下依賴的包:

  implementation("com.google.guava:guava:27.0.1-jre")
  implementation("commons-codec:commons-codec:1.11")
  implementation("com.auth0:java-jwt:3.8.0")
  compile(files("libs/mixin-java-sdk.jar"))
  implementation("com.squareup.okhttp3:okhttp:3.12.1")
  implementation("com.squareup.okio:okio:2.2.2")
  implementation("com.google.code.gson:gson:2.8.5")
  implementation("org.bouncycastle:bcprov-jdk16:1.46")
  implementation("org.apache.commons:commons-csv:1.6")
  implementation("org.msgpack:msgpack-core:0.8.16")
  implementation("com.fasterxml.jackson.core:jackson-databind:2.9.8")
  implementation("com.fasterxml.jackson.core:jackson-core:2.9.8")
  implementation("org.jetbrains.kotlin:kotlin-stdlib:1.3.30")
充幣到 Mixin Network, 并讀出它的余額.

通過ExinCore API, 可以進行BTC, USDT, EOS, ETH 等等交易, 此處演示用 USDT購買BTC 或者 用BTC購買USDT。交易前,先檢查一下錢包地址。
完整的步驟如下:

檢查比特幣或USDT的余額,錢包地址。并記下錢包地址。

從第三方交易所或者你的冷錢包中,將幣充到上述錢包地址。

再檢查一下幣的余額,看到帳與否。(比特幣的到帳時間是5個塊的高度,約100分鐘)。

比特幣與USDT的充值地址是一樣的。

  private static final String BTC_ASSET_ID     = "c6d0c728-2624-429b-8e0d-d9d19b6592fa";
  private static final String EOS_ASSET_ID     = "6cfe566e-4aad-470b-8c9a-2fd35b49c68d";
  private static final String USDT_ASSET_ID    = "815b0b1a-2764-3736-8faa-42d694fa620a";

  MixinAPI mixinApiUser = generateAPI_FromCSV();
  JsonObject asset = mixinApiUser.getAsset(BTC_ASSET_ID);
  System.out.println(asset);
  System.out.println("------------------------BTC------Information---------------------------");
  System.out.println("The BTC wallet address is " + asset.get("public_key").getAsString());
  System.out.println("The BTC wallet balance is " + asset.get("balance").getAsString());
  System.out.println("-----------------------------------------------------------------------");
查詢ExinCore市場的價格信息

如何來查詢ExinCore市場的價格信息呢?你要先了解你交易的基礎幣是什么,如果你想買比特幣,賣出USDT,那么基礎貨幣就是USDT;如果你想買USDT,賣出比特幣,那么基礎貨幣就是比特幣.

  if ( input.equals("8") ) {
   JsonArray res = FetchExinOneMarketInfos(USDT_ASSET_ID);
   System.out.println("--exchange_asset--exchange_asset_symbol/base_asset_symbol--price--minimum--maximum--exchanges--");
   // System.out.println(res);
   res.forEach((element) ->  {
      JsonObject jsonObj = element.getAsJsonObject();
      System.out.println(jsonObj.get("exchange_asset").getAsString() + " " +
                         jsonObj.get("exchange_asset_symbol").getAsString() + "/" +
                         jsonObj.get("base_asset_symbol").getAsString() + " " +
                         jsonObj.get("price").getAsString() + " " +
                         jsonObj.get("minimum_amount").getAsString() + " " +
                         jsonObj.get("maximum_amount").getAsString() + " " +
                         jsonObj.get("exchanges").getAsString() );
   });
   System.out.println("-----------------------------------------------------------------------");
  }
  private static JsonArray FetchExinOneMarketInfos(String url) {
    OkHttpClient client = new OkHttpClient();
    String baseUrl = "https://exinone.com/exincore/markets?base_asset=";
    String fullUrl = baseUrl + url;
    Request request = new Request.Builder()
                               .url(fullUrl)
                               .build();
    try {
       Response response = client.newCall(request).execute();
       if (!response.isSuccessful()) {
         throw new IOException("Unexpected code " + response);
       }
       return processJsonObjectWithDataOrError(response.body().string());
     } catch(Exception e) { e.printStackTrace(); }
     return null;
  }
  public static JsonArray processJsonObjectWithDataOrError(String res) {
   JsonParser parser = new JsonParser();
   JsonElement jsonTree = parser.parse(res);
   if ( jsonTree.isJsonObject() ) {
     if ( jsonTree.getAsJsonObject().get("data") != null ) {
        return  jsonTree.getAsJsonObject().get("data").getAsJsonArray();
     }
   }
   return null;
  }
交易前,創建一個Memo!

在第二章里,基于Mixin Network的 Java 比特幣開發教程: 機器人接受比特幣并立即退還用戶, 我們學習過退還用戶比特幣,在這里,我們除了給ExinCore支付幣外,還要告訴他我們想購買的幣是什么,即將想購買的幣存到memo里。

public static String encodeUUID(UUID uuid) {
  try {
    byte[] byteUuid = asBytes(uuid);
    MessageBufferPacker packer = MessagePack.newDefaultBufferPacker();
    packer.writePayload(byteUuid);
    packer.close();
    byte[] packedData = packer.toByteArray();
    byte[] prex = { (byte)129, (byte)161, 65, (byte)196, 16 };
    ByteArrayOutputStream output = new ByteArrayOutputStream();
    output.write(prex);
    output.write(packedData);
    byte[] out = output.toByteArray();
    return Base64.getEncoder().encodeToString(out);
  } catch (Exception e) { e.printStackTrace(); }
    return null;
}
幣幣交易的完整流程

轉幣給ExinCore時,將memo寫入你希望購買的幣,否則,ExinCore會直接退幣給你!
如果你想賣出比特幣買入USDT,調用方式如下:

private static final String EXIN_BOT         = "61103d28-3ac2-44a2-ae34-bd956070dab1";
private static final String BTC_ASSET_ID     = "c6d0c728-2624-429b-8e0d-d9d19b6592fa";
private static final String EOS_ASSET_ID     = "6cfe566e-4aad-470b-8c9a-2fd35b49c68d";
private static final String USDT_ASSET_ID    = "815b0b1a-2764-3736-8faa-42d694fa620a";
private static final String BTC_WALLET_ADDR  = "14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C";
private static final String MASTER_UUID      = "0b4f49dc-8fb4-4539-9a89-fb3afc613747";

if ( input.equals("5") ) {
 MixinAPI mixinApiUser = generateAPI_FromCSV();
 UUID usdtUUID         =  UUID.fromString(USDT_ASSET_ID);
 String memoTarget     = encodeUUID(usdtUUID);
 System.out.println("------------------------USDT-BTC-EXCHANGE----------------------------");
 System.out.println(memoTarget);
 JsonObject asset = mixinApiUser.getAsset(BTC_ASSET_ID);
 System.out.println(asset);
 System.out.println(asset.get("balance").getAsFloat());
 if ( (asset.get("balance").getAsFloat() * 10000) >= 1 ) {
     JsonObject transInfo = mixinApiUser.transfer(BTC_ASSET_ID, EXIN_BOT,
                                                "0.0001",memoTarget);
     System.out.println("------------------------BTC Transfer To EXCHANGE Information----------------------");
     System.out.println(transInfo);
     System.out.println("-----------------------------------------------------------------------");
  } else System.out.println("-----------------------------------------------------------------------");
}

如果你想賣出USDT買入比特幣,調用方式如下:

if ( input.equals("6") ) {
 MixinAPI mixinApiUser = generateAPI_FromCSV();
 UUID btcUUID          =  UUID.fromString(BTC_ASSET_ID);
 String memoTarget     = encodeUUID(btcUUID);
 System.out.println(memoTarget);
 System.out.println("-------------------------BTC-USDT-EXCHANGE----------------------------");
 JsonObject asset = mixinApiUser.getAsset(BTC_ASSET_ID);
 System.out.println(asset);
 if ( asset.get("balance").getAsFloat() >= 1 ) {
     JsonObject transInfo = mixinApiUser.transfer(USDT_ASSET_ID, EXIN_BOT,
                                                "1",memoTarget);
     System.out.println("------------------------USDT-BTC  EXCHANGE Information----------------------");
     System.out.println(transInfo);
     System.out.println("-----------------------------------------------------------------------");
  } else System.out.println("-----------------------------------------------------------------------");
}

交易完成后,Exincore會將你需要的幣轉到你的帳上,同樣,會在memo里,記錄成交價格,交易費用等信息!你只需要按下面的方式解開即可!

getSnapshots 讀取錢包的交易記錄。

if ( input.equals("7") ) {
  MixinAPI mixinApiUser = generateAPI_FromCSV();
  String transDatetime  = "";
  String assetUUID      = "";
  if ( mixinApiUser.getClientID().equals("091651f2-19c3-34f0-b45e-724ff203d921") ) {
    transDatetime = "2019-04-19T06:53:22.593529Z";
    assetUUID     = USDT_ASSET_ID;
  } else {
    System.out.print("Input the transaction Date time (eg:2019-04-19T06:53:22.593529Z):");
    transDatetime = System.console().readLine();
  }
  JsonArray snapshots = mixinApiUser.getSnapshots(assetUUID,3,transDatetime,"ASC");
  // System.out.println(snapshots);
  snapshots.forEach((element) ->  {
     JsonObject jsonObj = element.getAsJsonObject();
     if ( jsonObj.get("amount").getAsFloat() > 0 && jsonObj.get("data") != null ) {
       System.out.println(jsonObj.get("data").getAsString() );
       try {
       byte[] encoded = Base64.getDecoder().decode(jsonObj.get("data").getAsString());
       MessageUnpacker unpacker = MessagePack.newDefaultUnpacker(encoded);
       Value memoVal = unpacker.unpackValue();
       if ( memoVal.isMapValue()) {
         Map map = memoVal.asMapValue().map();
         System.out.println(map.size());
         if ( map.get(ValueFactory.newString("C")).asIntegerValue().asInt() == 1000 ) {
           System.out.println("Exchange successful" + " Code: " +
                              map.get(ValueFactory.newString("C")).asIntegerValue());
           System.out.println("Price is " + map.get(ValueFactory.newString("P")).asStringValue());
           System.out.println("Fee is " + map.get(ValueFactory.newString("F")).asStringValue());
           System.out.println("Type is " + map.get(ValueFactory.newString("T")).asStringValue());
           ByteBuffer AssetBinValue = map.get(ValueFactory.newString("FA")).asRawValue().asByteBuffer();
           System.out.println("Fee is asset UUID is  " + ByteBufferAsUuid(AssetBinValue));
           ByteBuffer TraceBinValue = map.get(ValueFactory.newString("O")).asRawValue().asByteBuffer();
           System.out.println("The trace id is " + ByteBufferAsUuid(TraceBinValue));
        }
       }
      } catch(Exception e) { e.printStackTrace(); }
     }
  });
}

一次成功的交易如下:

讀取幣的余額

通過讀取幣的余額,來確認交易情況!

MixinAPI mixinApiUser = generateAPI_FromCSV();
JsonObject asset = mixinApiUser.getAsset(BTC_ASSET_ID);
源代碼執行

編譯執行,即可開始交易了.

gradle build 編譯項目.

java -cp 運行項目.

java -cp .:build/libs/bitcoin_wallet-java.jar:libs/* bitcoin_wallet.java.App
