我如何制作一个表单，点击后提交到 node.js 快递服务器

Question

I tried but it doesn't work any idea?

this is my code:

res.get("/signin", function(req, res) {
     res.render("signin")
     console.log(req.body)
}

when it shows undefined and if I use body-parser it doesn't log when submitted instead it logs {} to the console

Generally speaking — there are some exceptions but not when the client is a browser — you will not get a request body on a GET request.

If you are submitting a <form> then you need to make a POST request to get a body.

• Set the method attribute of the <form>
• Configure express with a .post() route and not a .get() route.
