nodejs拷贝文件

nodejs拷贝文件，跟python一样方便

const fs = require('fs-extra');
const ps = require('path');

(async () => {
    let arrName = [
        'xx.proto',
    ]
    for (let i = 0; i < arrName.length; i++) {
        const fname = arrName[i];
        const orgnurl = ps.join(__dirname, '..', '..', 'Proto', fname);
        const oururl = ps.join(__dirname, '..', '..', 'Proto', 'protobuf', fname);
        var originalData = await fs.readFile(orgnurl, 'utf-8');
        originalData = originalData.replace(`option go_package = "../protocol";`, `package Pb;`)
        await fs.writeFile(
            oururl,
            originalData
        );
    }
})();

然后执行node ./copyPb.js，拷贝成功~！
