说在前面：

请先阅读此文章：ERC20 代币 API 调用-前期准备（一）

一、查看合约对象可调用的 api 接口

在JS交互窗口中输入：

cfcContract

得到以下输出： 

1> cfcContract
2{
3  abi: [{
4      constant: true,
5      inputs: [],

169  symbol: function(),
170  totalSupply: function(),
171  transfer: function(),
172  transferFrom: function(),
173  unfreeze: function(),
174  withdrawEther: function()
175}
176> 

返回到控制台的结果就是你可以调用的各个接口。

二、简单实例如何调用接口

1将智能合约中的eth代币转出：
2- withdrawEther方法调用
3web3.eth.defaultAccount = "0xbb438852706212284ff8E1ED6dA7F000e9ecd1A6"
4personal.unlockAccount("私钥")
5cfcContract.withdrawEther(75000000000000000)
6
7代币销毁：
8- burn方法调用
9personal.unlockAccount("私钥")
10cfcContract.burn(100000000000000000000) // 由于该cfc代币的denamic为18，所以要销毁的数量=数量*10^18
11
12代币冻结：
13- freeze方法调用
14personal.unlockAccount("私钥")
15cfcContract.freeze(100000000000000000000)
16
17代币解冻：
18- unfreeze方法调用
19personal.unlockAccount("私钥")
20cfcContract.unfreeze(100000000000000000000)

以上只使用了部分接口，其他接口都雷同。

web3.eth.defaultAccount 方法是指定默认账户，可代替 from（发送方的账户）
