從終端呼叫乙太坊 TokenERC20 合約：在私有乙太坊區塊鏈上轉移乙太幣或代幣
我在 3 個不同的節點上建立了一個私有乙太坊區塊鏈。
然後我使用乙太坊錢包在區塊鏈上部署了以下標準 TokenERC20 合約：
pragma solidity ^0.4.16; interface tokenRecipient { function receiveApproval(address _from, uint256 _value, address _token, bytes _extraData) public; } contract TokenERC20 { // Public variables of the token string public name; string public symbol; uint8 public decimals = 18; // 18 decimals is the strongly suggested default, avoid changing it uint256 public totalSupply; // This creates an array with all balances mapping (address => uint256) public balanceOf; mapping (address => mapping (address => uint256)) public allowance; // This generates a public event on the blockchain that will notify clients event Transfer(address indexed from, address indexed to, uint256 value); // This notifies clients about the amount burnt event Burn(address indexed from, uint256 value); /** * Constrctor function * * Initializes contract with initial supply tokens to the creator of the contract */ function TokenERC20( uint256 initialSupply, string tokenName, string tokenSymbol ) public { totalSupply = initialSupply * 10 ** uint256(decimals); // Update total supply with the decimal amount balanceOf[msg.sender] = totalSupply; // Give the creator all initial tokens name = tokenName; // Set the name for display purposes symbol = tokenSymbol; // Set the symbol for display purposes } /** * Internal transfer, only can be called by this contract */ function _transfer(address _from, address _to, uint _value) internal { // Prevent transfer to 0x0 address. Use burn() instead require(_to != 0x0); // Check if the sender has enough require(balanceOf[_from] >= _value); // Check for overflows require(balanceOf[_to] + _value > balanceOf[_to]); // Save this for an assertion in the future uint previousBalances = balanceOf[_from] + balanceOf[_to]; // Subtract from the sender balanceOf[_from] -= _value; // Add the same to the recipient balanceOf[_to] += _value; Transfer(_from, _to, _value); // Asserts are used to use static analysis to find bugs in your code. They should never fail assert(balanceOf[_from] + balanceOf[_to] == previousBalances); } /** * Transfer tokens * * Send `_value` tokens to `_to` from your account * * @param _to The address of the recipient * @param _value the amount to send */ function transfer(address _to, uint256 _value) public { _transfer(msg.sender, _to, _value); } /** * Transfer tokens from other address * * Send `_value` tokens to `_to` in behalf of `_from` * * @param _from The address of the sender * @param _to The address of the recipient * @param _value the amount to send */ function transferFrom(address _from, address _to, uint256 _value) public returns (bool success) { require(_value <= allowance[_from][msg.sender]); // Check allowance allowance[_from][msg.sender] -= _value; _transfer(_from, _to, _value); return true; } /** * Set allowance for other address * * Allows `_spender` to spend no more than `_value` tokens in your behalf * * @param _spender The address authorized to spend * @param _value the max amount they can spend */ function approve(address _spender, uint256 _value) public returns (bool success) { allowance[msg.sender][_spender] = _value; return true; } /** * Set allowance for other address and notify * * Allows `_spender` to spend no more than `_value` tokens in your behalf, and then ping the contract about it * * @param _spender The address authorized to spend * @param _value the max amount they can spend * @param _extraData some extra information to send to the approved contract */ function approveAndCall(address _spender, uint256 _value, bytes _extraData) public returns (bool success) { tokenRecipient spender = tokenRecipient(_spender); if (approve(_spender, _value)) { spender.receiveApproval(msg.sender, _value, this, _extraData); return true; } } /** * Destroy tokens * * Remove `_value` tokens from the system irreversibly * * @param _value the amount of money to burn */ function burn(uint256 _value) public returns (bool success) { require(balanceOf[msg.sender] >= _value); // Check if the sender has enough balanceOf[msg.sender] -= _value; // Subtract from the sender totalSupply -= _value; // Updates totalSupply Burn(msg.sender, _value); return true; } /** * Destroy tokens from other account * * Remove `_value` tokens from the system irreversibly on behalf of `_from`. * * @param _from the address of the sender * @param _value the amount of money to burn */ function burnFrom(address _from, uint256 _value) public returns (bool success) { require(balanceOf[_from] >= _value); // Check if the targeted balance is enough require(_value <= allowance[_from][msg.sender]); // Check allowance balanceOf[_from] -= _value; // Subtract from the targeted balance allowance[_from][msg.sender] -= _value; // Subtract from the sender's allowance totalSupply -= _value; // Update totalSupply Burn(_from, _value); return true; } }然後在一個 geth 控制台上，我使用以下命令同步了這個合約：
var abi = contractInterface //i gave actual interface here var address = contractAddress //i gave actual address where contract is deployed var adder1 = eth.contract(abi).at(address)然後在geth控制台上列印
adder1顯示：> adder1 { abi: [{ constant: true, inputs: [], name: "name", outputs: [{...}], payable: false, stateMutability: "view", type: "function" }, { constant: false, inputs: [{...}, {...}], name: "approve", outputs: [{...}], payable: false, stateMutability: "nonpayable", type: "function" }, { constant: true, inputs: [], name: "totalSupply", outputs: [{...}], payable: false, stateMutability: "view", type: "function" }, { constant: false, inputs: [{...}, {...}, {...}], name: "transferFrom", outputs: [{...}], payable: false, stateMutability: "nonpayable", type: "function" }, { constant: true, inputs: [], name: "decimals", outputs: [{...}], payable: false, stateMutability: "view", type: "function" }, { constant: false, inputs: [{...}], name: "burn", outputs: [{...}], payable: false, stateMutability: "nonpayable", type: "function" }, { constant: true, inputs: [{...}], name: "balanceOf", outputs: [{...}], payable: false, stateMutability: "view", type: "function" }, { constant: false, inputs: [{...}, {...}], name: "burnFrom", outputs: [{...}], payable: false, stateMutability: "nonpayable", type: "function" }, { constant: true, inputs: [], name: "symbol", outputs: [{...}], payable: false, stateMutability: "view", type: "function" }, { constant: false, inputs: [{...}, {...}], name: "transfer", outputs: [], payable: false, stateMutability: "nonpayable", type: "function" }, { constant: false, inputs: [{...}, {...}, {...}], name: "approveAndCall", outputs: [{...}], payable: false, stateMutability: "nonpayable", type: "function" }, { constant: true, inputs: [{...}, {...}], name: "allowance", outputs: [{...}], payable: false, stateMutability: "view", type: "function" }, { inputs: [{...}, {...}, {...}], payable: false, stateMutability: "nonpayable", type: "constructor" }, { anonymous: false, inputs: [{...}, {...}, {...}], name: "Transfer", type: "event" }, { anonymous: false, inputs: [{...}, {...}], name: "Burn", type: "event" }], address: "0xA8113a44aCC20305ce9f2Cd7CC067562b8f54d6c", transactionHash: null, Burn: function(), Transfer: function(), allEvents: function(), allowance: function(), approve: function(), approveAndCall: function(), balanceOf: function(), burn: function(), burnFrom: function(), decimals: function(), name: function(), symbol: function(), totalSupply: function(), transfer: function(), transferFrom: function() }直到這裡一切似乎都執行良好。現在，當我嘗試使用如下傳遞函式時：
adder1.transfer("0x542b2103c2cf18ce6e22d5099bee3db32e984641",33000000000000000000)它給了我錯誤：
Error: invalid address at web3.js:3930:15 at web3.js:3756:20 at web3.js:5025:28 at map (<native code>) at web3.js:5024:12 at web3.js:5050:18 at web3.js:5075:23 at web3.js:4137:16 at apply (<native code>) at web3.js:4223:16或者即使我這樣做：
adder1.transferFrom(eth.accounts[0],"0x542b2103c2cf18ce6e22d5099bee3db32e984641",33000000000000000000)我得到錯誤：
Error: invalid address at web3.js:3930:15 at web3.js:3756:20 at web3.js:5025:28 at map (<native code>) at web3.js:5024:12 at web3.js:5050:18 at web3.js:5075:23 at web3.js:4137:16 at apply (<native code>) at web3.js:4223:16它甚至沒有為調試提供任何線索。
問題：有人可以幫助我如何使用上述部署的合約從終端發送乙太幣或代幣。
僅供參考
TokenERC20： [https://www.ethereum.org/token]$$ 1 $$非常歡迎在這種情況下提供任何幫助或更好的理解。
我已經為此花費了幾個小時，但無能為力。
我自己找到了一個可行的答案：
請參閱：如何使用 geth 將 ERC20 代幣（GNT、OMG 等）從冷錢包轉移到另一個賬戶（或交易所）
這就是我所做的：
var abi = contractInterface var address = contractAddress var adder1 = eth.contract(abi).at(address) var fromAccount = "0x7a52a05a2a2f3c9ed8b1297db5399c0c3adfa5c2".toLowerCase() var destAccount = "0x542b2103c2cf18ce6e22d5099bee3db32e984641".toLowerCase() adder1.transfer(destAccount,web3.toWei(20,"ether"),{from:fromAccount})
