Solution 1
Sure, here is a Python program that uses the requests library to retrieve all the products from the API server and print the total number of products currently stored in the server.
import requests
import json
# Define the base URL
base_url = "http://host1.open.uom.lk:8080"
# Send a GET request to the server
response = requests.get(base_url)
# Convert the response to JSON
data = response.json()
# Check if the request was successful
if data['message'] == 'success':
# Print the total number of products
print("Total number of products: ", len(data['data']))
else:
print("Failed to retrieve data")
This program first sends a GET request to the server. It then converts the server's response to JSON format. If the 'message' field in the response is 'success', it prints the total number of products by getting the length of the 'data' field. If the 'message' field is not 'success', it prints an error message.
Solution 2
Sure, here is a Python program that uses the requests library to retrieve all the products from the API server and print the total number of products currently stored in the server.
import requests
import json
# Define the base URL
base_url = "http://host1.open.uom.lk:8080"
# Send a GET request to the server
response = requests.get(base_url)
# Convert the response to JSON
data = response.json()
# Get the list of products from the data
products = data["data"]
# Print the total number of products
print("Total number of products: ", len(products))
This program works by sending a GET request to the server, which should return a JSON response containing all the products. The json() method is used to convert this response into a Python dictionary, and the "data" key is used to access the list of products. The len() function is then used to count the number of products in this list.
