如何使用flask请求编写删除文件中某些行的方法？

pip install flask
from flask import Flask, request

app = Flask(__name__)

@app.route('/delete-lines', methods=['POST'])
def delete_lines():
    file_path = request.form.get('file_path')  # 获取文件路径
    lines_to_delete = request.form.get('lines_to_delete')  # 获取要删除的行数

    try:
        with open(file_path, 'r') as file:
            lines = file.readlines()

        lines_to_delete = [int(line) for line in lines_to_delete.split(',')]
        lines = [line for i, line in enumerate(lines) if i+1 not in lines_to_delete]

        with open(file_path, 'w') as file:
            file.writelines(lines)

        return 'Lines deleted successfully.'
    except Exception as e:
        return str(e)

if __name__ == '__main__':
    app.run()
