【问题描述】：

我遇到错误“处理交易请求时出错：处理交易时出现 VM 异常：堆栈下溢”，基本上适用于任何合同。我正在使用 Ganache v2.1.2 和 Web3j 4.5.15。 Ganache CLI v6.9.1（ganache-core：2.10.2）也是如此。我可以毫无问题地使用 Remix IDE 和 Metamask 插件部署合约。

Java 代码：

public class contractCR
  

    static class OSCGasProvider implements ContractGasProvider
           

        public OSCGasProvider()

        @Override
        public BigInteger getGasPrice(String string)
                      
           return Convert.toWei("1", Convert.Unit.GWEI).toBigInteger();             
                 

        @Override
        public BigInteger getGasLimit(String string)
          
            return BigInteger.valueOf(3000000);
          

        @Override
        public BigInteger getGasPrice()
          
            throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
          

        @Override
        public BigInteger getGasLimit()
          
            throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
          

      

    public static void main (String args[])
      
        System.out.println("Connecting to Ethereum ...");
        Web3j web3 = Web3j.build(new HttpService("http://localhost:7545"));
        System.out.println("Successfuly connected to Ethereum");
        try 
          
            // web3_clientVersion returns the current client version.
            Web3ClientVersion clientVersion = web3.web3ClientVersion().send();
            Credentials credentials=Credentials.create(privateKey);
            Faucet osc = Faucet.deploy(web3, credentials, new OSCGasProvider()).send();
            String contractAddress = osc.getContractAddress();
            System.out.println("The contract address is: "+contractAddress);
            
        catch (IOException ex)
          
            throw new RuntimeException("Error while sending json-rpc requests", ex);
          
        catch (Exception ex)
          
              System.out.println(ex.toString());
               
      

简单的水龙头合约：

// Version of Solidity compiler this program was written for
pragma solidity ^0.5.12;

// Our first contract is a faucet!
contract Faucet 

    address payable owner_addr; //the owner address

    //initialize the contract
    constructor() public 
    
      owner_addr=msg.sender;
    

    //contract destructor
    modifier owner_allowed
    
      require (msg.sender==owner_addr, "Only contract owner is allowed to call this function");    
      _;
    

    function destroy() public owner_allowed
    
      selfdestruct(owner_addr);
    

    // Give out ether to anyone who asks
    function withdraw(uint withdraw_amount) public
     
        // Limit withdrawal amount
        require(withdraw_amount <= 100000000000000000); //0.1ether
        // Send the amount to the address that requested it
        msg.sender.transfer(withdraw_amount);
    

    // Accept any incoming amount
    function () external payable  //fallback or default function

【参考方案1】：

看起来这是一个与 Ganache 相关的问题 https://github.com/trufflesuite/ganache-cli/issues/465

根据我的测试，它可以很好地运行我本地的 Ganache 2.1.2

【讨论】：

所以，我猜今天没有解决办法。

我不确定您是否尝试过以下操作： 1. 重新启动 ganache 2. 尝试不同的 ganache 版本 3. 使用一个私有 geth 节点而不是 ganache 您的代码可以正常运行，无需停留我认为甘纳许

【参考方案2】：

我终于找到了问题所在。 Web3j-cli 不接受 Remix-IDE 提供的二进制文件，而只接受“二进制”字段。将仅包含二进制数据的文件作为输入提供给 Web3j-cli 会生成正确的包装器。
