Modify the getfile.py used during class to allow user to enter a customized file name instead of fixed original file name. The interface should have three data controls: (1) The file Selector, which can be made by using “input name=file1 type=file ” (2) The saving file name, which can be made by using “input name=fn ” (3) The Submit button, which can be made by “input type=submit name=submit value=Upload ” Don't use template. Submit the python program

auto-modify-the-file-names.zip_names

在IT行业中，尤其是在数据处理和自动化任务中，批量修改文件名是一项常见的需求。"auto-modify-the-file-names.zip_names" 提供的工具或脚本显然就是针对这一需求的解决方案。这个压缩包可能包含一个或多个VB（Visual Basic）脚本，用于在当前目录下批量替换文件的名称，以实现快速、高效地管理大量文件。我们要理解VB脚本的基础。VB是Microsoft Visual Basic的缩写，是一种基于事件驱动的编程语言，它简单易学且功能强大，常被用来编写Windows应用程序和脚本。在VB脚本中，可以使用FileSystemObject（FSO）对象来操作文件系统，包括读取、写入、创建、移动和重命名文件。批量修改文件名通常涉及以下几个关键步骤： 1. 创建FSO对象：`Set fso = CreateObject("Scripting.FileSystemObject")` 2. 遍历目录中的文件：使用`fso.GetFolder(".")`获取当前目录，然后通过`Folder.Files`属性获取所有文件。 3. 对每个文件执行重命名操作：`fso.MoveFile "原文件名", "新文件名"` 4. 替换字符串：如果需要根据某种规则（例如替换特定字符或字符串）来修改文件名，可以使用字符串函数如`Replace()`。例如，以下是一个简单的VB脚本片段，它会将所有文件名中的"oldstring"替换为"newstring"： ```vb Sub RenameFiles() Dim fso As Object Set fso = CreateObject("Scripting.FileSystemObject") Dim folder As Object Set folder = fso.GetFolder(".") Dim file As Object For Each file In folder.Files newName = Replace(file.Name, "oldstring", "newstring") If file.Name <> newName Then fso.MoveFile file.Path, folder.Path & "\" & newName End If Next file End Sub ``` 在这个过程中，`Replace()`函数用于查找并替换文件名中的特定文本，`MoveFile()`方法则负责实际的重命名操作。这样的脚本对于整理和规范化大量的数据文件非常有用，特别是在需要统一文件命名格式或者清理含有敏感信息的文件名时。 "auto-modify-the-file-names.zip_names"中的VB脚本很可能是类似的实现，但具体的实现细节需要解压并查看源代码才能得知。使用这类工具时，用户应确保了解脚本的工作原理，避免误修改重要文件。同时，为了保证数据安全，最好先在备份的文件集上测试脚本，确认无误后再应用于目标文件夹。

Sure, here's the modified `getfile.py` script that allows the user to enter a customized file name: ```python #!/usr/bin/env python3 import cgi import os # Set the upload directory UPLOAD_DIR = '/path/to/upload/directory/' # Create the form object form = cgi.FieldStorage() # Get the uploaded file object fileitem = form['file1'] # Get the custom file name from the form filename = form['fn'].value # Check if the file was uploaded if fileitem.filename: # Create the upload directory if it doesn't exist if not os.path.isdir(UPLOAD_DIR): os.makedirs(UPLOAD_DIR) # Set the file path filepath = UPLOAD_DIR + filename # Open the file for writing in binary mode with open(filepath, 'wb') as f: # Read the file in chunks while True: chunk = fileitem.file.read(1024) if not chunk: break # Write the chunk to the file f.write(chunk) # Print a success message print('Content-type:text/html\r\n\r\n') print('<html>') print('<head>') print('<title>File Upload</title>') print('</head>') print('<body>') print('<h2>File Uploaded Successfully</h2>') print('</body>') print('</html>') else: print('Content-type:text/html\r\n\r\n') print('<html>') print('<head>') print('<title>File Upload Error</title>') print('</head>') print('<body>') print('<h2>Error: No File Specified</h2>') print('</body>') print('</html>') ``` This script uses the `cgi` module to handle the form data, and allows the user to enter a custom file name using an additional form input. The custom file name is then used to save the uploaded file to the upload directory.
