const express = require('express');
const app = express();

app.get('/', (req, res) => {
  // Example code where a request parameter is expected
  const paramValue = req.query.param;

  if (!paramValue) {
    res.status(400).send('Bad Request - Missing parameter');
  } else {
    // Continue with the normal flow of the application
    // ...
    res.send('Success!');
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

http status codes 400

Comment

# HTTP status code 400 is "Bad Request". It indicates that the server could not understand the request due to invalid syntax or missing parameters.
# Here's an example of how to handle a 400 response using Python requests library:

import requests

url = "https://api.example.com/endpoint"
headers = {
    "Content-Type": "application/json"
}
data = {
    "invalid_field": "invalid_value"
}

response = requests.post(url, headers=headers, json=data)

if response.status_code == 400:
    print("Bad Request: The server rejected the request due to invalid syntax or missing parameters.")
    print(response.json())  # Display the response body if available
else:
    print("Request successful")
