将数据保存到 a.json

Question

I need to store data from a html form to.json file, but instead i'm getting this:

http://localhost:3000/teachers/create?avatar_url=&name=&birth=&grade=medio&class_type=P&lesson=

Javascript code for this:

const fs = require("fs");
const data = require("./data.json");

exports.post = function (req, res) {
    const keys = Object.keys(req.body);

    for (key of keys) {
        if (req.body[key] == "") {
            return res.send("Please, fill in all fields!");
        }
    }

    let { avatar_url, birth, name, grade, class_type, lesson } = req.body;

    birth = Date.parse(birth);
    const created_at = Date.now();
    const id = Number(data.teachers.length + 1);

    data.teachers.push({
        id,
        name,
        avatar_url,
        birth,
        grade,
        class_type,
        lesson,
        created_at,
    });

    fs.writeFile("data.json", JSON.stringify(data, null, 2), function (err) {
        if (err) return res.send("Write file error!");

        return res.redirect("/teachers");
    });

    //return res.send(req.body);
};

It's impossible to say without seeing your code, but my guess based on your question is that your html <form> doesn't have method="post" , so it's submitting as a GET. That would account for why you're seeing the params in the URL query string, and why your handler—which appears to be set up for POST requests—isn't doing what you expect, because that handler isn't receiving this request.
