动态失败使用passport.js重定向 [英] Dynamic failureRedirect with passport.js

问题描述

这是我的登录功能atm:

This is my login function atm:

app.post("/login", passport.authenticate("local", {
    failureRedirect: "/login?error=1"
}), function (req, res) {
    res.redirect(req.body.url || "/");
});

我需要将req.body.url放在failureRedirect网址中，所以它应该像这样:

I need to put the req.body.url inside the failureRedirect url, so it should looks like:

app.post("/login", passport.authenticate("local", {
    failureRedirect: "/login?error=1&url=" + (req.body.url || "/")
}), function (req, res) {
    res.redirect(req.body.url || "/");
});

它不起作用，因为req变量仅在post的回调内部初始化...我该怎么办?

It can't work because the req variable is inited only inside the callback of post... how can I do?

推荐答案

您可以使用自定义回调动态生成回调URL，因为其中可以使用req对象.

You can use Custom Callbacks to dynamically generate callbacks urls, as the req object is available inside them.
