Use the node.js server as restful app server

One may use the node.js server as a means to get acquainted with restful services. Let us assume this server is installed and started with

json-server "C:\Users\tomva\SynologyDrive\python\json server\db.json" --port 8000

We can then see the json database within the browser “http://localhost:8000/extra”. We may add some information by:

import requests
import json
api_url = "http://localhost:8000/extra"
todo = {"userId": 1, "title": "Buy nore sugar", "completed": False}
headers =  {"Content-Type":"application/json"}
response = requests.post(api_url, data=json.dumps(todo), headers=headers)
print(response.json())
print(response.status_code)

Data is added with ‘id’: ‘8701’. This id is important if one would like to change some data. Look at the put methode that is used below:

import requests
import json

url = 'http://localhost:8000/extra/8701'
data = {"id": 3,"userId": 2, "title": "drink beer",  "body": "drinking beer is nice"}
headers = {'Content-Type':'application/json; charset=UTF-8'}
response = requests.put(url, data=json.dumps(data), headers=headers)

print(response.status_code)
print(response.text)

The data can be retrieved with the get method:

import requests
api_url = "http://localhost:8000/extra/8701"
response = requests.get(api_url)
response.json()
print(response.text)
print(response.status_code)

The response.text contains the data:

import requests
import json

url = 'http://localhost:8000/extra/8701'
headers = {'Content-Type': 'application/json; charset=UTF-8'}
response = requests.delete(url, headers=headers)
print(response.status_code) # 200
print(response.ok) # True
