我建议将返回HTML内容写入一个文件，并使用以下命令来抓取本地文件：

import scrapy
import os

LOCAL_FILENAME = 'example.html'
LOCAL_FOLDER = 'html_files'
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

class ExampleSpider(scrapy.Spider):
    name = "example"
    start_urls = [
        f"file://{BASE_DIR}/{LOCAL_FOLDER}/{LOCAL_FILENAME}"
    ]
