Python Requests File Upload Example

Uploading files using the requests library is very simple. Below is a complete example showing how to upload a file using requests, including basic error handling.

File Upload Example

import requests

def upload_file(file_path, url):
    """Upload a file to the specified URL"""
    try:
        # Open the file and upload it
        with open(file_path, 'rb') as file:
            files = {'file': file}  # Dictionary of file parameters
            response = requests.post(url, files=files)  # Send a POST request
            
            # Check the response status
            response.raise_for_status()  # If the response status code is not 200-299, an exception will be thrown
            
            # Return JSON response
            return response.json()  # Assume the server returns JSON format data
    except requests.RequestException as e:
        print(f'File upload failed: {e}')
    except FileNotFoundError:
        print('File not found, please check the path')
    except Exception as e:
        print(f'An error occurred: {e}')

if __name__ == '__main__':
    # Replace with the actual file path and API address
    file_path = 'example.txt'  # The path of the file to upload
    url = 'https://api.example.com/upload'  # Upload target URL
    
    upload_response = upload_file(file_path, url)
    if upload_response:
        print('Upload Successfully:', upload_response)
