一、getweb3.js的定义

1.先定义一组变量，留着后面使用

2.将智能合约的地址引入，记得每次重新部署智能合约之后都要重新修改

3.将智能合约的ABI码引入，将ABI码赋值给一个变量，记得每次更新智能合约的地址之后都要更新对应的智能合约的ABI码。

4.使用定义连接区块链的函数，将networkVersion设置成为自己的链ID ，使用web3设置currentProvider （这步是和链连接上了），在第二个红框中new一个合约的时候将智能合约的地址和ABI码赋予第一步所定义的变量（这步是找到合约）。

5.将合约中所实现的 public 方法分别引入，当引入的这个方法会修改智能合约中的数据的时候使用send方法，当引入的方法不会修改智能合约中的数据的时候使用call方法，红框代表的是引入哪个合约，这个变量是在第四步中定义的。

6 、将上面实现的所有方法记得全部导出在一个模块中

合约中的所有方法和在getweb3.js中定义的所有方法都要导出。

 二、Vue中main.js中的修改

1.将getweb3.js中导出模块中的方法全部引入

2.为实例定义全局作用域，这样在Vue的实例中就可以使用，比如在Vue的所有实例中都可以使用$addExperimentInfo。

 三、在Vue文件中使用智能合约中的方法

 在Vue中使用js语言定义一个方法，在方法中可以使用第二步定义好全域使用的方法
