本文档介绍了如何在Ethers.js中使用可读的ABI（人类可读的ABI）来初始化合约方法，特别是涉及struct类型的参数。示例包括构造函数、转移函数、余额查询以及处理struct类型的方法如`addPerson`、`addPeople`和`getPerson`。此外，还展示了如何处理struct数组和触发事件。

Ethersjs human readable abi

ethersjs 使用可阅读的abi方式初始化合约rpc方法时，应该如何填写，以至于可以正确使用struct类型进行传参。填写方式如下，来源于ethers文档官网

const humanReadableAbi = [

  // Simple types
  "constructor(string symbol, string name)",
  "function transferFrom(address from, address to, uint value)",
  "function balanceOf(address owner) view returns (uint balance)",
  "event Transfer(address indexed from, address indexed to, address value)",
  "error InsufficientBalance(account owner, uint balance)",

  // Some examples with the struct type, we use the tuple keyword:
  // (note: the tuple keyword is optional, simply using additional
  //        parentheses accomplishes the same thing)
  // struct Person {
  //   string name;
  //   uint16 age;
  // }
  "function addPerson(tuple(string name, uint16 age) person)",
  "function addPeople(tuple(string name, uint16 age)[] person)",
  "function getPerson(uint id) view returns (tuple(string name, uint16 age))",

  "event PersonAdded(uint indexed id, tuple(string name, uint16 age) person)"
];
