Scrapy CrawlSpider重试刮擦

我会考虑使用 自定义的Retry
Middleware

，它类似于内置的。

实施示例（未经测试）：

import logginglogger = logging.getLogger(__name__)class RetryMiddleware(object):    def process_response(self, request, response, spider):        if 'var PageIsLoaded = false;' in response.body: logger.warning('parse_page encountered an incomplete rendering of {}'.format(response.url)) return self._retry(request) or response        return response    def _retry(self, request):        logger.debug("Retrying %(request)s", {'request': request})        retryreq = request.copy()        retryreq.dont_filter = True        return retryreq

并且不要忘记激活它。
