I want to log all the query parameters which are passed to my endpoint. whenever they call me ie through GET , POST. i am able to print all the GET query params but struggling with POST params.
i used req.body but that doesnt work it just prints [Object object] even JSON.stringify didnt help.
Can any one point me to right source to look for it

We can access these route parameters on our req. params object using the syntax shown below. app. get(/:id, (req, res) => { const id = req.params.id; });
In Express. js, you can directly use the req. query() method to access the string variables.
Your query parameters can be retrieved from the query object on the request object sent to your route. It is in the form of an object in which you can directly access the query parameters you care about. In this case Express handles all of the URL parsing for you and exposes the retrieved parameters as this object.
Parameter: The options parameter contains various properties like extended, inflate, limit, verify, etc. Return Value: It returns an Object. Example: Let’s discuss each step one by one to receive post parameters in the express.js Step 1: Create an “ app.js ” file and initialize your project using npm.
Replace app.get () on line 18 with app.post (). On lines 20, 21 and 22, replace the query method with the body method. So instead of: Do the same for last_name and gender as well. Go ahead, run the server. Now you will be able to handle POST request using Express framework in Node.js.
Here is an example of a URL with query strings attached: The query parameters are the actual key-value pairs like page and limit with values of 2 and 3, respectively. Now, let's move on to the first main purpose of this article - how to extract these from our Express request object.
In order to see the Node.js Express REST API GET method in action, do the following: Open up the node.js command prompt from your start menu. Type node and then the path where your node.js server is, followed by the server file name. In our case, it will be: c:\wamp\www ode\server.js
So POST parameters arrive in the HTTP request body, and this is handled as a stream of data chunks by node.js. So the first thing you must do is make sure you assemble the stream of chunks into a complete piece of data. Then you may want to parse it as either url encoded or JSON if that's what it is. The standard middleware for this is body-parser. You set it up like they say in the README:
const express = require('express')
const bodyParser = require('body-parser')
const app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
// parse application/vnd.api+json as json
app.use(bodyParser.json({ type: 'application/vnd.api+json' }))
app.use(function (req, res, next) {
console.log(req.body) // populated!
next()
})
