如何进行快速路由，使mysql删除特定ID的查询

Question

I'm trying to make a post request in express that when fired, deletes a row in my Tasks MySQL table, which is connected to a specific user ID. I'm not sure how to go about it... I think I have to use req.params.id in my code somewhere, but I don't know if thats all I need or if thats even right to begin with.

Here is what I have so far:

const express = require("express");
const app = express();
const mysql = require("mysql");
const bodyParser = require("body-parser");

app.use(bodyParser.urlencoded({extended: true}));

const connection = mysql.createConnection({
        host: "localhost",
        user: "root",
        password: "PASSWORD",
        database: "DATABASE"
    });

connection.connect(function(err) {
    if (err) {
        console.log("Your connection to the database failed \n");
    } else {
        console.log("Your connection to the database was successful \n")
    }
});

app.post("/deleteTask", function(req, res) {
    let remove = "DELETE FROM Tasks WHERE "; // finish the query

    connection.query(remove, function(err, result) {
        if (err) {
            console.log("The delete query failed");
            res.sendStatus(500);
            throw err;
        } else {
            res.sendStatus(200);
            console.log(result);
        }
        connection.end();
    });
});

Yes, first I suggest you to read the doc about routing : https://expressjs.com/en/guide/routing.html

After If it was my jobs I'll get the taskId with something like

app.post("/deleteTask/:taskId", function(req, res) {
    const taskId = req.params.taskId;

    let remove = "DELETE FROM Tasks WHERE "; // finish the query
    ...
});
