如何将CSV文件对象传递给falcon响应

import falcon
import csv

class CSVResource:
    def on_get(self, req, resp):
        # 读取CSV文件数据
        data = self.read_csv_file('path/to/csv/file.csv')
        
        # 设置响应头，指定Content-Type为text/csv
        resp.content_type = 'text/csv'
        
        # 将CSV数据作为响应体返回
        resp.body = data
    
    def read_csv_file(self, file_path):
        # 读取CSV文件
        with open(file_path, 'r') as file:
            csv_data = file.read()
        
        return csv_data

app = falcon.App()
csv_resource = CSVResource()
app.add_route('/csv', csv_resource)

if __name__ == '__main__':
    host = '127.0.0.1'  # 主机地址
    port = 8000  # 端口号
    
    httpd = simple_server.make_server(host, port, app)
    httpd.serve_forever()
