How to Upload Files Using Python Requests Library

We are given some files and our task is to upload it using request library of Python. In this article, we're going to discover a way to use the requests library to add files in diverse scenarios, such as uploading unmarried documents, multiple files, and documents with extra form statistics

Upload Files Using Python Requests Library

Below, are the examples of Python Upload Files With Python's Requests Library. Before diving into file upload examples, let's ensure you have the requests library installed. If not, you can install it using pip:

pip install requests

Below, are the methods of uploading files with Python's Requests library

• Using files parameter
• Using data parameter
• Using multipart/form-data directly
• Sending as raw binary data

Upload Files Using Files Parameter

In this example, below code uses the Python requests library to upload a file (file.txt) to the specified URL (https://httpbin.org/post) using a POST request with the files parameter, and then prints the response text.

import requests

url = 'https://httpbin.org/post'
files = {'file': open('file.txt', 'rb')}  # Specify the file you want to upload

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

print(response.text)

Output

{
  "args": {}, 
  "data": "", 
  "files": {
    "file": "GeeksforGeeks"
  }, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Content-Length": "157", 
    "Content-Type": "multipart/form-data; boundary=c4e3e1f85303491ffd523537762f87bc", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.31.0", 
    "X-Amzn-Trace-Id": "Root=1-65fbfabc-4d943f6b5851070275fbb946"
  }, 
  "json": null, 
  "origin": "157.34.0.92", 
  "url": "https://httpbin.org/post"
}

Upload Files Using Data Parameter

In this example, below Python code sends a POST request to "https://httpbin.org/post", including both form data ('key': 'value') and a file ('file.txt') uploaded via the `requests` library. It then prints the response received from the server.

import requests

url = 'https://httpbin.org/post'
data = {'key': 'value'}  # Additional data if required

with open('file.txt', 'rb') as file:
    response = requests.post(url, data=data, files={'file': file})

print(response.text)

Output

{
  "args": {}, 
  "data": "", 
  "files": {
    "file": "GeeksforGeeks"
  }, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Content-Length": "157", 
    "Content-Type": "multipart/form-data; boundary=c4e3e1f85303491ffd523537762f87bc", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.31.0", 
    "X-Amzn-Trace-Id": "Root=1-65fbfabc-4d943f6b5851070275fbb946"
  }, 
  "json": null, 
  "origin": "157.34.0.92", 
  "url": "https://httpbin.org/post"
}

Upload Files Using Multipart/Form-data Directly

In this example, below Python code uses the requests library to perform a POST request to https://httpbin.org/post, uploading the file example.txt with the specified content type of multipart/form-data. The server's response is then printed.

import requests

url = 'https://httpbin.org/post'
files = {'file': ('example.txt', open('example.txt', 'rb'),
                  'multipart/form-data')}

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

print(response.text)

Output

{
  "args": {}, 
  "data": "", 
  "files": {
    "file": "GeeksforGeeks"
  }, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Content-Length": "157", 
    "Content-Type": "multipart/form-data; boundary=c4e3e1f85303491ffd523537762f87bc", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.31.0", 
    "X-Amzn-Trace-Id": "Root=1-65fbfabc-4d943f6b5851070275fbb946"
  }, 
  "json": null, 
  "origin": "157.34.0.92", 
  "url": "https://httpbin.org/post"
}

Sending as Raw Binary Data

In this example, below code sends a POST request to 'https://httpbin.org/post' with a header specifying the content type as 'application/octet-stream'. It uploads the contents of the file 'file.txt' as raw binary data. The server's response is then printed.

import requests

url = 'https://httpbin.org/post'
# Specify the content type
headers = {'Content-Type': 'application/octet-stream'}
data = open('file.txt', 'rb').read()

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

print(response.text)

Output

{
  "args": {}, 
  "data": "", 
  "files": {
    "file": "GeeksforGeeks"
  }, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Content-Length": "157", 
    "Content-Type": "multipart/form-data; boundary=c4e3e1f85303491ffd523537762f87bc", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.31.0", 
    "X-Amzn-Trace-Id": "Root=1-65fbfabc-4d943f6b5851070275fbb946"
  }, 
  "json": null, 
  "origin": "157.34.0.92", 
  "url": "https://httpbin.org/post"
}
