发送交易时报错

[liuzhijun23]

我在本地建立了一条私有链，用你的SDK的例子，查询余额操作正常，但是在发送交易的时候，报错： 我的程序是： `public class TestEOS { public static String url_wallet = "http://192.168.1.75:18888"; public static String url_chain = "http://192.168.1.75:8888";//"http://jungle.cryptolions.io:18888" public static EosApi client; public static void main(String[] args) throws Exception{ BasicConfigurator.configure(); client = EosApiFactory.create(url_wallet, url_chain, url_chain); ChainInfo info = client.getChainInfo(); //System.out.println("chain info:"+info);

   // getBalance("acctoken","acca");

    transfer("acctoken","acca","accb","100.0000 SYS");
    TimeUnit.MINUTES.sleep(50000);
}

static void getBalance(String token,String account){
    List<String> ret = client.getCurrencyBalance(token,account,"SYS");
    System.out.println("account balance:"+ret);
}

static void transfer(String token,String from,String to,String money) throws Exception {
    ObjectMapper mapper = EosApiServiceGenerator.getMapper();

    // ① pack transfer data
    TransferArg transferArg = new TransferArg(from, to, money, "我是中国人");
    AbiJsonToBin data = client.abiJsonToBin(token, "transfer", transferArg);
    System.out.println("bin= " + data.getBinargs());

    // ② get the latest block info
    Block block = client.getBlock(client.getChainInfo().getHeadBlockId());
    System.out.println("blockNum=" + block.getBlockNum());

    // ③ create the authorization
    List<TransactionAuthorization> authorizations = Arrays.asList(new TransactionAuthorization(from, "active"));

    // ④ build the all actions
    List<TransactionAction> actions = Arrays.asList(//
            new TransactionAction(token, "transfer", authorizations, data.getBinargs())//
    );

    // ⑤ build the packed transaction
    PackedTransaction packedTransaction = new PackedTransaction();
    packedTransaction.setRefBlockPrefix(block.getRefBlockPrefix());
    packedTransaction.setRefBlockNum(block.getBlockNum());
    // expired after 3 minutes
    String expiration = ZonedDateTime.now(ZoneId.of("GMT")).plusMinutes(3).truncatedTo(ChronoUnit.SECONDS).format(DateTimeFormatter.ISO_LOCAL_DATE_TIME);
    packedTransaction.setExpiration(LocalDateTime.parse(expiration));
    packedTransaction.setRegion("0");
    packedTransaction.setMaxNetUsageWords(0);
    packedTransaction.setMaxCpuUsageMs(0);
    packedTransaction.setActions(actions);

    // ⑥ unlock the creator's wallet
    try {
        client.unlockWallet("default", "PW5JECR3XedNovw8w8cPmYBe52eH51buki4rVVHUwunWFeJNco4Vd");
    } catch (EosApiException ex) {
        System.err.println(ex.getMessage());
    }

    // ⑦ sign the transaction
    SignedPackedTransaction signedPackedTransaction = client.signTransaction(packedTransaction, //
            Arrays.asList("EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"), //
            "38dc6e87bb9f6b33a21dd56b9f2c24813d83c71009077279c8d746fbd0eaf09d");

    System.out.println("signedPackedTransaction=" + mapper.writeValueAsString(signedPackedTransaction));
    System.out.println("\n--------------------------------\n");

    // ⑧ push the signed transaction
    PushedTransaction pushedTransaction = client.pushTransaction("none", signedPackedTransaction);
    System.out.println("pushedTransaction=" + mapper.writeValueAsString(pushedTransaction));
}

} 报的错误是： Exception in thread "main" io.jafka.jeos.exception.EosApiException: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of io.jafka.jeos.core.common.transaction.TransactionAuthorization (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator) at [Source: (okhttp3.ResponseBody$BomAwareReader); line: 1, column: 242] (through reference chain: io.jafka.jeos.core.common.transaction.SignedPackedTransaction["actions"]->java.util.ArrayList[0]->io.jafka.jeos.core.common.transaction.TransactionAction["authorization"]->java.util.ArrayList[0]) at io.jafka.jeos.impl.EosApiServiceGenerator.executeSync(EosApiServiceGenerator.java:64) at io.jafka.jeos.impl.EosApiRestClientImpl.signTransaction(EosApiRestClientImpl.java:210) at org.web3j.sample.TestEOS.transfer(TestEOS.java:95) at org.web3j.sample.TestEOS.main(TestEOS.java:46) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144) Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of io.jafka.jeos.core.common.transaction.TransactionAuthorization (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator) at [Source: (okhttp3.ResponseBody$BomAwareReader); line: 1, column: 242] (through reference chain: io.jafka.jeos.core.common.transaction.SignedPackedTransaction["actions"]->java.util.ArrayList[0]->io.jafka.jeos.core.common.transaction.TransactionAction["authorization"]->java.util.ArrayList[0]) at com.fasterxml.jackson.databind.exc.InvalidDefinitionException.from(InvalidDefinitionException.java:67) at com.fasterxml.jackson.databind.DeserializationContext.reportBadDefinition(DeserializationContext.java:1452) at com.fasterxml.jackson.databind.DeserializationContext.handleMissingInstantiator(DeserializationContext.java:1028) at com.fasterxml.jackson.databind.deser.BeanDeserializerBase.deserializeFromObjectUsingNonDefault(BeanDeserializerBase.java:1297) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserializeFromObject(BeanDeserializer.java:326) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:159) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:286) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:245) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:27) at com.fasterxml.jackson.databind.deser.impl.MethodProperty.deserializeAndSet(MethodProperty.java:127) at com.fasterxml.jackson.databind.deser.BeanDeserializer.vanillaDeserialize(BeanDeserializer.java:288) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:151) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:286) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:245) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:27) at com.fasterxml.jackson.databind.deser.impl.MethodProperty.deserializeAndSet(MethodProperty.java:127) at com.fasterxml.jackson.databind.deser.BeanDeserializer.vanillaDeserialize(BeanDeserializer.java:288) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:151) at com.fasterxml.jackson.databind.ObjectReader._bindAndClose(ObjectReader.java:1611) at com.fasterxml.jackson.databind.ObjectReader.readValue(ObjectReader.java:1203) at retrofit2.converter.jackson.JacksonResponseBodyConverter.convert(JacksonResponseBodyConverter.java:32)16:23:48.399 [main] INFO io.jafka.jeos.impl.LoggingInterceptor - OkHttp-6-3--<head http://192.168.1.75:18888/v1/wallet/sign_transaction 9ms Connection: close`

看起来是无法反序列化，你将反序列化失败的文本输出来看看。

另外内容可以markdown格式化下

[liuzhijun23]

我现在在仿真，在源码里面打断点调试

[adyliu]

已经修复了此问题，临时发布了SNAPSHOT版本 https://github.com/adyliu/jeos#latest-snapshot-version

0.9.14版本 http://repo1.maven.org/maven2/io/jafka/jeos/0.9.14/ 已经发布，预计未来几个小时会同步到全网。

[liuzhijun23]

新版本有Gradle版本吗？

[adyliu]

可以了 已经同步了

compile group: 'io.jafka', name: 'jeos', version: '0.9.14'

[liuzhijun23]

功能已经正常了，可以正常转账了，给大神点赞!

[liuzhijun23]

请问大神一个问题，如果在android App上面调用这个库来转账，上面说的在线转账需要启动keosd服务所以不能用，这种情况需要用离线签名转账方式。这个函数： localApi.transfer(arg, privateKey, from1, to1, quantity, memo); 它在哪里设置代币名称（比如eosio.token）？

[liuzhijun23]

`@Override public PushTransactionRequest transfer(SignArg arg, String privateKey, String from, String to, String quantity, String memo) { // ① pack transfer data TransferArg transferArg = new TransferArg(from, to, quantity, memo); String transferData = Packer.packTransfer(transferArg); //

    // ③ create the authorization
    List<TransactionAuthorization> authorizations = Arrays.asList(new TransactionAuthorization(from, "active"));

    // ④ build the all actions
    List<TransactionAction> actions = Arrays.asList(//
            new TransactionAction("eosio.token", "transfer", authorizations, transferData)//
    );

    // ⑤ build the packed transaction
    PackedTransaction packedTransaction = new PackedTransaction();
    packedTransaction.setExpiration(arg.getHeadBlockTime().plusSeconds(arg.getExpiredSecond()));
    packedTransaction.setRefBlockNum(arg.getLastIrreversibleBlockNum());
    packedTransaction.setRefBlockPrefix(arg.getRefBlockPrefix());

    packedTransaction.setMaxNetUsageWords(0);
    packedTransaction.setMaxCpuUsageMs(0);
    packedTransaction.setDelaySec(0);
    packedTransaction.setActions(actions);

    String hash = sign(privateKey, arg, packedTransaction);
    PushTransactionRequest req = new PushTransactionRequest();
    req.setTransaction(packedTransaction);
    req.setSignatures(Arrays.asList(hash));
    return req;
}`

这里已经把代币名称(eosio.token)写死在函数源码里，需要设置成参数让用户去设置。

@liuzhijun23 Hi I want to know where is sign method (String hash = sign(privateKey, arg, packedTransaction); ) is located?

Thanks you so much!

[lecletest]

I have a smart contract with the method name is crepoll how can I call it from java and write the record to blockchain? @liuzhijun23 @adyliu
