Create an empty promise that just fulfills?
提问by Himmators
I have a wrapper that catches the last result of a promise, formats it and outputs the data:
我有一个包装器，可以捕获承诺的最后一个结果，对其进行格式化并输出数据：
req.resolve = (promise) => {
return promise.then(() => {
res.json(req.user);
}).catch(Sequelize.ValidationError, err => {
// respond with validation errors
return res.status(422).send(err.errors);
}).catch(err => {
// every other error
return res.status(400).send({ message: err.message });
});
};
In one view, I don't have a promise, all that happens is that the auth-function triggers adds req.user and triggers done().
一方面，我没有承诺，所有发生的都是 auth-function triggers 添加 req.user 和 triggers done()。
I tried adding a promise like this, but it doesn't get resolved.
我尝试添加这样的承诺，但没有得到解决。
app.get('/user/me', auth,
(req, res, next) => {
req.resolve(new Promise());
});

Promiseconstructor requires executor function as parameter. Substitute Promise.resolve()for new Promise()
Promise构造函数需要执行器函数作为参数。替代Promise.resolve()的new Promise()
