walletConnet2.0 使用更新迁移

walletConnet1.0 已经被遗弃，2.0不向前兼容，所以在项目中使用1.0的必须更新2.0

以前的初始化写法

import WalletConnectProvider from "@walletconnect/web3-provider";
import {ethers } from "ethers";
export  function getWalletProvider() {
    const provider = new WalletConnectProvider({
        chainId: 56,
        rpc: {
            56: "https://bsc-dataseed1.defibit.io/"
        }
    });
    const WalletProvider = new ethers.providers.Web3Provider(provider)
    return {
        WalletProvider,
        provider
    };
}

现在的写法

1.安装最新的包 npm i @walletconnect/ethereum-provider @walletconnect/modal
3.walletConnet官网地址  
https://docs.walletconnect.com/2.0/advanced/migration-from-v1.x/dapps/

2.在使用vuecli3 时候需要在vue.confing.js 文件中加入

　　transpileDependencies: ['@walletconnect'],

module.exports = {
  transpileDependencies: ['@walletconnect'],
  configureWebpack: {
     ...
  }

import { EthereumProvider } from '@walletconnect/ethereum-provider'
import { ethers } from "ethers";

export async function getWalletProvider() {

    const provider = await EthereumProvider.init({
        projectId: 'c45c72189ab8cff2c9b1dc103bd3455d', // required 需要自己去申请免费的，可用于多个项目
        chains: [56],
        showQrModal: true,
    });
    // await provider.enable()
    // const result = await provider.request({ method: 'eth_requestAccounts' })
    const WalletProvider = new ethers.providers.Web3Provider(provider)
    return {
        WalletProvider,
        provider
    };
}
