you can include "redirect" as a property within json, for instance:您可以将“重定向”作为 json 中的一个属性,例如:
res.json({ auth: true, token: token, message: "success", redirect : "/whatever/go"});
then, on the client side you can perform the redirecting like this:然后,在客户端,您可以像这样执行重定向:
fetch(url)
.then(res => res.json())
.then(body => window.location.href = body.redirect)
.catch(err => console.log(err));
