要在Bus.emitObject方法调用结束后再返回rest值，你可以将整个操作包装在一个Promise中，并使用async/await来处理异步操作。以下是修改后的代码示例：
import Bus from "../eventBus";
const post = async (req, res, next) => {
try {
const {...body} = req.body;
const bankData = await BankBase.findByPk(body.id);
if (!bankData) {
return res.sendStatus(404);
} else {
const rest = await new Promise((resolve, reject) => {
Bus.emitObject(bankData.event, {data: body}, (result) => {
resolve(result);
});
});
return res.json({code: 200, data: rest.rest});
}
} catch (error) {
return res.json({msg: '该银行还未注册，请先注册。'});
}
};
module.exports = {
post
};
这样，当Bus.emitObject方法调用完成并返回结果后，才会继续执行后面的代码并返回rest值给客户端。
