Python Requests Passing Parameters in URLs
Description:
You often want to send some sort of data in the URL%u2019s query string. If you were constructing the URL by hand, this data would be given as key/value pairs in the URL after a question mark, e.g.
httpbin.org/get?key=val. Requests allows you to provide these arguments as a dictionary of strings, using the params keyword argument. As an example, if you wanted to pass key1=value1 and key2=value2 to httpbin.org/get, you would use the following code:Code:
# importing requests library
import requests
# storing arguements to be passed in a variable
payload = {'key1': 'value1', 'key2': 'value2'}
# passing the above parameters with request.get() method
r = requests.get('https://httpbin.org/get', params=payload)
print(r.url)
Output:
>>>https://httpbin.org/get?key1=value1&key2=value2
- Note that any dictionary key whose value is
Nonewill not be added to the URL%u2019s query string. - You can also pass a list of items as a value:
For example:
Code:
# importing requests library
import requests
# storing arguements to be passed in a variable
payload = {'key1': 'value1', 'key2': ['value2', 'value3']}
# passing the above parameters with request.get() method
r = requests.get('https://httpbin.org/get', params=payload)
print(r.url)
Output:
>>>https://httpbin.org/get?key1=value1&key2=value2&key2=value3
