我有一个必须创建屏幕截图的简单的抓蜘蛛。以下是我的代码,但出现错误:

回溯(最近通话最近):   _runCallbacks中的第654行“ c:\ users \ xxxxx \ appdata \ local \ programs \ python \ python37 \ lib \ site-packages \ twisted \ internet \ defer.py”     current.result =回调(current.result,* args,** kw)   文件“ C:\ Users \ xxxxxx \ scrapy_screenshot \ scrapy_screenshot \ spiders \ extract.py”,第19行,位于parse_result中     imgdata = base64.b64decode(response.data ['png']) AttributeError:“ HtmlResponse”对象没有属性“ data”

import json
import base64
import scrapy
from scrapy_splash import SplashRequest


class ExtractSpider(scrapy.Spider):
    name = 'extract'

    def start_requests(self):
        url = 'https://stackoverflow.com/'
        splash_args = {
            'html': 1,
            'png': 1
        }
        yield SplashRequest(url, self.parse_result, endpoint='render.json', args=splash_args)

    def parse_result(self, response):
        imgdata = base64.b64decode(response.data['png'])
        filename = 'some_image.png'
        with open(filename, 'wb') as f:
            f.write(imgdata)
