Python Requests Post File

If you want to send a file to a website using Python Requests, you can use the post method. You can do this in a few different ways.

Method 1: Use the files parameter

The first method involves using the files parameter of the post method.

Here's an example:


import requests

url = 'http://example.com/upload'
files = {'file': open('file.txt', 'rb')}

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

In this example, we're sending a file called file.txt to the URL http://example.com/upload. We're opening the file in binary mode and including it as the value of a dictionary with the key 'file'. We then pass this dictionary to the files parameter of the post method.

The response object will contain the server's response to our request.

Method 2: Use the data parameter and set the Content-Type header

The second method involves using the data parameter and setting the Content-Type header to 'multipart/form-data'.

Here's an example:


import requests

url = 'http://example.com/upload'
headers = {'Content-Type': 'multipart/form-data'}
data = open('file.txt', 'rb').read()

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

In this example, we're sending the contents of the file file.txt to the URL http://example.com/upload. We're setting the Content-Type header to 'multipart/form-data', which tells the server that we're sending a file. We're also reading the contents of the file into a variable called data. We then pass this variable to the data parameter of the post method.

The response object will contain the server's response to our request.

Method 3: Use the data parameter and encode the file as base64

The third method involves using the data parameter and encoding the file as base64.

Here's an example:


import requests
import base64

url = 'http://example.com/upload'
data = {'file': base64.b64encode(open('file.txt', 'rb').read())}

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

In this example, we're sending a file called file.txt to the URL http://example.com/upload. We're reading the contents of the file into a variable called data, encoding it as base64 using the b64encode method of the base64 module, and including it as the value of a dictionary with the key 'file'. We then pass this dictionary to the data parameter of the post method.

The response object will contain the server's response to our request.
