cita-java-sdk中的Transaction问题

#1

Transaction(String to, BigInteger nonce, long quota, long valid_until_block, int version, int chainId, String value, String data)中的version,chainId,value是随便取值的吗?不包含Token的合约,value有什么作用?

#2

而且 0.23.0版本的jar包中,chainId类型是BigInteger,文档里还是int

#3
  • Version 指的是 CITA 的协议版本
  • chainId 指的是当前链的 id, 你可以用 getMetaData 接口获得；
  • value 指的是本次交易的转帐金额。

都不是可以随例取值。

#4

谢谢你的反馈，我们会尽快更新文档的

#5

文档已更新 https://github.com/cryptape/cita-sdk-java/blob/develop/docs/index.md。

如果还有其他问题，后续可以再讨论，谢谢。

#6

好的,辛苦:grinning:

#7

对于部署合约或其非转账交易,value取0就行?

#8

是的。如果你写非 0 , 就会有一笔 value 从你的帐户转到合约帐户。

#9

AppSendTransaction result = service.appSendRawTransaction(rawTx).send();
发送交易后,result是空,会是什么原因?

#10

@DuanYangyang, 你晓得这是什么问题吗？

#11

result 有错误信息吗？还是什么信息都没有？能贴一下返回值吗？谢谢

#12

result is empty.
result.getSendTransactionResult() is null

#13

这是我的代码
public static void main(String[] args) {
long currentHeight = 0L;
long validUntilBlock = currentHeight + 80;
Random random = new Random(System.currentTimeMillis());
String nonce = String.valueOf(Math.abs(random.nextLong()));
long quota = 1000000;
Transaction tx = Transaction.createContractTransaction(nonce, quota, validUntilBlock,1, BigInteger.ZERO,“0”,

CITAj service = CITAj.build(new HttpService(“http://121.196.200.225:1337/”));

在这行代码之前，加一行代码，打开 http 请求的 log 开关。

HttpService.setDebug(true);

然后开一下最原始的 Http 请求日志，麻烦把日志贴一下，谢谢。

{“jsonrpc”:“2.0”,“id”:0,“error”:{“code”:-32006,“message”:“BadChainId”}}

#16

ChainId 有误

#17

先用 getMetaData 看一下 chainId 是多少。

#18

我用你们的测试网络 curl -X POST --data ‘{“jsonrpc”:“2.0”,“method”:“getMetaData”,“params”:[“0xff”],“id”:0}’ 121.196.200.225:1337
结果:
{“jsonrpc”:“2.0”,“id”:0,“error”:{“code”:-32003,“message”:“Query chain name failed”}}
用我本地的 curl -X POST --data ‘{“jsonrpc”:“2.0”,“method”:“getMetaData”,“params”:[“0xff”],“id”:1}’ 127.0.0.1:1337
结果
{“jsonrpc”:“2.0”,“id”:1,“result”:{“chainId”:0,“chainIdV1”:“0x1”,“chainName”:“test-chain”,“operator”:“test-operator”,“website”:“https://www.example.com”,“genesisTimestamp”:1555661275807,“validators”:[“0x012fb22a531da103f55b4d1806156837c4ef225a”,“0x3a991f59c42afc3a5a3a39723c6b0d938e2261c4”,“0xf6615342b6d86c27029aee5ea46dd39784a24d4d”,“0xdaff028df55cd9ecb4b9b9e296f8bc88a7636f0f”],“blockInterval”:3000,“tokenName”:“CITA Test Token”,“tokenSymbol”:“CTT”,“tokenAvatar”:“https://cdn.cryptape.com/icon_cita.png",“version”:1,"economicalModel”:0}}.
会是因为chainId类型吗?我传的是BigInteger.ZERO

curl -X POST --data ‘{“jsonrpc”:“2.0”,“method”:“getMetaData”,“params”:[“latest”],“id”:1}’ 121.196.200.225:1337 使用这个查询吧，查询最新块

#20

curl -X POST --data ‘{“jsonrpc”:“2.0”,“method”:“getMetaData”,“params”:[“latest”],“id”:1}’ 121.196.200.225:1337

{“jsonrpc”:“2.0”,“id”:1,“result”:{“chainId”:0,“chainIdV1”:“0x1”,“chainName”:“test-chain”,“operator”:“test-operator”,“website”:“https://www.example.com”,“genesisTimestamp”:1541058686340,“validators”:[“0xc489d5cb6f497e4708cc8c3805473b9528f83c7a”,“0x497c68f02bbe335cc879356af120371ebf6cbc29”,“0x6fbb4c8bb76ace631d634545fe39cbee979dd08e”,“0x3c0f681e13f18b51d5350823eae45cb502231cf4”],“blockInterval”:3000,“tokenName”:“CITA Test Token”,“tokenSymbol”:“CTT”,“tokenAvatar”:“https://cdn.cryptape.com/icon_cita.png",“version”:1,"economicalModel”:1}}
chainId是0没问题啊
