Because embed.Files implements fs.FS, it cannot provide access to files with names beginning with .., so files in parent directories are also disallowed entirely, even when the parent directory named by .. does happen to be in the same module.
这个方法在运行的时候没有效果，不过在其他人可能是有效果的（我猜是因为我开发时很少直接用 go generate，都是直接 go run 了)。不过，这个方法也有个问题，因为是写在代码本身当中的，很有可能后续因为某些原因，这些代码被误删除或修改了，导致整个系统的运行不正常。而散落在各文件的描述也会使得修复十分复杂。
let writer = new ExcelWriter({
sheets: [{
name: 'Test Sheet',
key: 'tests',
headers: [{
name: 'Test Name',
key: 'name' }, {
name: 'Test Coverage',
key: 'testValue',
default: 0 }]
}]
});
let dataPromises = inputs.map((input) => {
// 'tests' is the key of the sheet. That is used// to add data to only the Test Sheet writer.addData('tests', input);
});
Promise.all(dataPromises)
.then(() => {
return writer.save();
})
.then((stream) => {
stream.pipe(fs.createWriteStream('data.xlsx'));
});

如果你需要将这些数据保存为一个单独的文件，只需要修改初始化的参数，并执行 save 方法，就可以将 JSON 导出到指定的文件中
var db = new Database({
path: "./test.json", // 将数据存储在 test.json 当中});
db.save();
Code language:JavaScript(javascript)
类似的，如果数据已经构建好了，也只需要执行 load 方法，就可以加载数据。
var db = new Database({
path: "./test.json", // 将数据存储在 test.json 当中});
db.load();
