要将这个异步函数转换为同步函数，可以使用async/await语法。下面是修改后的代码：
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 Bus.emitObject(bankData.event, {data: body});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。'});}};
通过在post函数定义前添加async关键字，使其成为一个异步函数。然后，在需要等待异步操作结果的地方，使用await关键字来等待异步操作完成。这样就能够以同步方式处理异步操作的结果了。
