Python Requests Post Content-Type Application/x-www-form-urlencoded

If you are trying to send data to a server using the HTTP POST method, you will need to use the Python Requests library. One of the most common Content-Types for sending data via POST is application/x-www-form-urlencoded.

In order to use this Content-Type, you will need to encode your data in a specific way. Each key-value pair needs to be separated by an equal sign (=) and each pair needs to be separated by an ampersand (&). Here is an example:


import requests

url = 'https://example.com'
data = {'username': 'john', 'password': 'doe'}

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

In this example, we are sending a POST request to 'https://example.com' and including two pieces of data: 'username' and 'password'. The data is encoded using the application/x-www-form-urlencoded Content-Type.

If you want to specify the Content-Type explicitly, you can pass a headers dictionary to the request. Here is an example:


import requests

url = 'https://example.com'
data = {'username': 'john', 'password': 'doe'}
headers = {'Content-Type': 'application/x-www-form-urlencoded'}

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

In this example, we are sending the same data as before, but we are explicitly setting the Content-Type to application/x-www-form-urlencoded using the headers dictionary.

Another way to send data using the application/x-www-form-urlencoded Content-Type is to pass a string instead of a dictionary. Here is an example:


import requests

url = 'https://example.com'
data = 'username=john&password=doe'

response = requests.post(url, data=data, headers={'Content-Type': 'application/x-www-form-urlencoded'})

In this example, we are sending the same data as before, but we are passing it as a string instead of a dictionary. The string is in the same format as before: each key-value pair is separated by an equal sign (=) and each pair is separated by an ampersand (&).
