我正试图在以太坊testrpc网络上部署我的可靠智能合约。 这是我的稳固合同:
pragma solidity ^0.4.11;
contract Fibonacci {
event Notify(uint input, uint result);
function fibonacci(uint number) constant returns(uint result) {
if (number == 0) return 0;
else if (number == 1) return 1;
else return Fibonacci.fibonacci(number - 1) + Fibonacci.fibonacci(number - 2);
}
function fibonacciNotify(uint number) returns(uint result) {
result = fibonacci(number);
Notify(number, result);
}
}
我正在使用web3j在以太坊testrpc网络中部署此合同,该网络现在只在一台计算机上运行。 以下是我在JAVA控制台中使用的命令:
Future<FibonacciZKF> fib= FibonacciZKF.deploy(Web3j.build(new HttpService()), ALICE, GAS_PRICE, GAS_LIMIT, BigInteger.valueOf(5));
我为上述合约生成了所有必要的abi和bin。
我甚至根据上述合同的指示生成了一个包装器。 这是我的合同包装:

private static final String BINARY = "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";

但是我无法在这个tetrpc以太坊网络上部署。谁能回答为什么?
答案 0 :(得分:2)
您必须检查您的客户是否有;连接到testnet并运行节点,或连接到连接到testnet的geth节点。
您能提供显示如何尝试连接到testnet的代码吗?
我可以通过以下方式附加到我的geth节点;
try {
web3j = Web3j.build(new HttpService("Http://localhost:8545"));
} catch (InterruptedException | ExecutionException e) {
e.printStackTrace();
}
