py7zr压缩文件

To use py7zr to encrypt a file with a password and send a RESTful message notifying the compression completion along with the output path as an extra parameter, you would need to follow these general steps:

1. Install the py7zr library: You can install py7zr using pip by running the following command:

   pip install py7zr
   1

2. Import the necessary modules: In your Python script, import the required modules:

   import py7zr
   import requests
   1
   2

3. Compress and encrypt the file: Use py7zr to create a compressed and encrypted 7-Zip archive with a password:

   def compress_and_encrypt_file(file_path, output_path, password):
       with py7zr.SevenZipFile(output_path, 'w', password=password) as archive:
           archive.writeall(file_path, '')

4. Send the RESTful message: Use the requests library to send a RESTful message with the output path as an extra parameter:

   def send_restful_message(url, output_path):
       payload = {'output_path': output_path}
       response = requests.post(url, json=payload)
       if response.status_code == 200:
           print("Compression notification sent successfully.")
       else:
           print("Failed to send compression notification.")

5. Invoke the functions: Call the functions with the appropriate arguments:

   file_path = '/path/to/file'
   output_path = '/path/to/output/archive.7z'
   password = 'your_password'
   url = 'https://your-rest-api-endpoint'
   
   compress_and_encrypt_file(file_path, output_path, password)
   send_restful_message(url, output_path)

In the compress_and_encrypt_file function, the SevenZipFile class from py7zr is used to create a new archive with the specified output path and password. The writeall method is used to add the file to the archive.

In the send_restful_message function, the requests library is used to send a POST request to the specified URL with the output path as a JSON payload.

Make sure to replace the placeholder values (file_path, output_path, password, and url) with your actual file path, output path, password, and RESTful API endpoint.

Remember to handle exceptions, perform error checking, and adapt the code to fit your specific requirements and environment.
