7. Query String Data Sender

Write a Python program to send some sort of data in the URL's query string.

Sample Solution:

Python Code:

import requests
payload = {'key1': 'value1', 'key2': 'value2'}
print("Parameters: ",payload)
r = requests.get('https://httpbin.org/get', params=payload)
print("Print the url to check the URL has been correctly encoded or not!")
print(r.url)
print("\nPass a list of items as a value:")
payload = {'key1': 'value1', 'key2': ['value2', 'value3']}
print("Parameters: ",payload)
r = requests.get('https://httpbin.org/get', params=payload)
print("Print the url to check the URL has been correctly encoded or not!")
print(r.url)

Sample Output:

Parameters:  {'key1': 'value1', 'key2': 'value2'}
Print the url to check the URL has been correctly encoded or not!
https://httpbin.org/get?key1=value1&key2=value2

Pass a list of items as a value:
Parameters:  {'key1': 'value1', 'key2': ['value2', 'value3']}
Print the url to check the URL has been correctly encoded or not!
https://httpbin.org/get?key1=value1&key2=value2&key2=value3
