使用geth向合同发送消息

Question

我有一个制造代币并将其转移的工作系统，具体如下-

> addrtoken.balanceOf(eth.accounts[0])
33333250
> addrtoken.balanceOf(eth.accounts[1])
50

我想测试buyTokens函数。这个函数使用msg.value，我不知道如何测试它。这是下面的内容。有没有办法把msg.value发送到geth？

 // fallback function to buy tokens
 function () payable {
   buyTokens(msg.sender);
 }

  /**
   * Low level token purchse function
    * @param beneficiary will recieve the tokens.
   */
  function buyTokens(address beneficiary) payable whenNotPaused {
    require(beneficiary != 0x0);
  require(validPurchase());


uint256 weiAmount = msg.value;
// update weiRaised
weiRaised = weiRaised.add(weiAmount);
// compute amount of tokens created
uint256 tokens = weiAmount.mul(rate);

token.mint(beneficiary, tokens);
TokenPurchase(msg.sender, beneficiary, weiAmount, tokens);
forwardFunds();
}

Answer 1

回退函数调用的buyToken函数。因此，必须触发回退函数，在geth控制台上如下所示：

eth.sendTransaction({from:eth.coinbase,to:addrtoken.address,value:10})

关于回退功能，请阅读此退却

希望能帮上忙~

尝尝这个,

MyToken.deployed().then(function(instance) { return instance.buyToken('0x0ab768ac22111fdd177085238a7b51f6270497d0','0x38a1f9f495fdef18f18073eef329945316a5d281',100);}).then(console.log());
