您好~非常感谢您的分享~ 最近在用爬取大众点评的评论数据， 想请问一下，您的代码里边 DaZhongDianPing->Spyder->Xiuxian->spiders comment_spider.py 的一点问题。

  1. 这个是怎么用的呢？直接把 CommentSpider(scrapy.Spider)实例化吗？还是有个main是可以把所有的spider都run起来呢？
  2. from scrapy.conf import settings 不知道您用的scrapy版本是多少，我的一直显示这个有问题： Module scrapy.conf is deprecated, use crawler.settings attribute instead
    Thanks♪(･ω･)ﾉ

你之前用过scrapy吗？ 我这边是没有用main函数串起来的，每次运行就scrapy crawl _spider.py这个命令就可以了 至于你说的另一个问题？是和版本有关吗，我不太清楚，我的是1.1.1，建议去stackoverflow找找看是否有你问题的答案.我直接把这个报错信息百度了一下，也出现了很多解决方案，建议逐个尝试一下

您好~感谢您的回复~ 现在跑通了 url_spider.py （我看见您这个代码是需要先把url写入mongo, 在其他_spider.py里边通过查询这个url来爬取其他内容的，不知道理解对不？） 下边是代码显示结果，不知道是没爬出来东西？还是没有写到mongo里边去？我在mongodb里边没有看到相关记录·~~ 2017-09-27 21:53:38 [scrapy.downloadermiddlewares.redirect] DEBUG: Redirecting (30 2) to <GET http://1.1.1.3:80/disable/disable.htm?url_type=%E8%AE%BF%E9%97%AE%E7%BD %91%E7%AB%99/%E8%BD%AF%E4%BB%B6%E4%B8%8B%E8%BD%BD&plc_name=%E5%8A%9E%E5%85%AC%E7%B D%91%E7%AD%96%E7%95%A5> from <GET http://1.1.1.3:80/disable/disable.htm?url_type=% E8%AE%BF%E9%97%AE%E7%BD%91%E7%AB%99/%E8%BD%AF%E4%BB%B6%E4%B8%8B%E8%BD%BD&plc_name= %E5%8A%9E%E5%85%AC%E7%BD%91%E7%AD%96%E7%95%A5> 2017-09-27 21:53:38 [scrapy.downloadermiddlewares.redirect] DEBUG: Discarding <GET http://1.1.1.3:80/disable/disable.htm?url_type=%E8%AE%BF%E9%97%AE%E7%BD%91%E7%AB% 99/%E8%BD%AF%E4%BB%B6%E4%B8%8B%E8%BD%BD&plc_name=%E5%8A%9E%E5%85%AC%E7%BD%91%E7%AD %96%E7%95%A5>: max redirections reached 2017-09-27 21:53:38 [scrapy.core.engine] INFO: Closing spider (finished) 2017-09-27 21:53:38 [scrapy.statscollectors] INFO: Dumping Scrapy stats: {'downloader/request_bytes': 22228, 'downloader/request_count': 43, 'downloader/request_method_count/GET': 43, 'downloader/response_bytes': 11168, 'downloader/response_count': 43, 'downloader/response_status_count/200': 1, 'downloader/response_status_count/302': 42, 'finish_reason': 'finished', 'finish_time': datetime.datetime(2017, 9, 27, 13, 53, 38, 949000), 'log_count/DEBUG': 44, 'log_count/INFO': 7, 'log_count/WARNING': 1, 'response_received_count': 1, 'scheduler/dequeued': 21, 'scheduler/dequeued/memory': 21, 'scheduler/enqueued': 21, 'scheduler/enqueued/memory': 21, 'start_time': datetime.datetime(2017, 9, 27, 13, 53, 23, 965000)} 2017-09-27 21:53:38 [scrapy.core.engine] INFO: Spider closed (finished) 再次感谢您的回复~~ @preke

你的理解是正确的，不过你遇到了302重定向问题，需要查找一下解决方案，可能是大众点评更新了反爬策略？

stutys commented 7 years ago

好的，非常感谢~ @preke

stutys commented 7 years ago

不好意思，我想再问一下，那个url是怎么写到数据库的呢？在url_spider.py里边没有看到连接数据库的代码~~~ 其他_spider里边貌似都有 @preke

stutys commented 7 years ago

对了，您好~您用的python版本是2.X吗？ 我用的3.6，middlewares.py里边 proxyAuth = "Basic " + base64.b64encode(proxyUser + ":" + proxyPass) 总是有问题，找一堆办法貌似没啥用~不知道这个在3.6里边应该怎么改呢？

stutys commented 7 years ago

您好，上面的问题都已经解决，也爬出来了一些数据，非常感谢~~~ 现在遇到一个问题是，正爬着的时候爬虫就关了，再次运行就出现下面的问题，是不是被封了呢？需要怎么修改才行呢?Thanks♪(･ω･)ﾉ 2017-09-28 18:03:04 [scrapy.utils.log] INFO: Scrapy 1.4.0 started (bot: Xiuxian) 2017-09-28 18:03:04 [scrapy.utils.log] INFO: Overridden settings: {'BOT_NAME': 'Xiuxian', 'CLOSESPIDER_ERRORCOUNT': 20, 'CONCURRENT_REQUESTS': 32, 'COOKIES_ENABLED': False, 'DOWNLOAD_DELAY': 0.3, 'NEWSPIDER_MODULE': 'Xiuxian.spiders', 'ROBOTSTXT_OBEY': True, 'SPIDER_MODULES': ['Xiuxian .spiders']} 2017-09-28 18:03:04 [scrapy.middleware] INFO: Enabled extensions: ['scrapy.extensions.corestats.CoreStats', 'scrapy.extensions.telnet.TelnetConsole', 'scrapy.extensions.closespider.CloseSpider', 'scrapy.extensions.logstats.LogStats'] ***** ['http://www.dianping.com/shop/38212967'] 2017-09-28 18:03:04 [scrapy.middleware] INFO: Enabled downloader middlewares: ['scrapy.downloadermiddlewares.robotstxt.RobotsTxtMiddleware', 'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware', 'scrapy.downloadermiddlewares.httpauth.HttpAuthMiddleware', 'Xiuxian.middlewares.RotateUserAgentMiddleware', 'scrapy.downloadermiddlewares.downloadtimeout.DownloadTimeoutMiddleware', 'scrapy.downloadermiddlewares.defaultheaders.DefaultHeadersMiddleware', 'scrapy.downloadermiddlewares.retry.RetryMiddleware', 'scrapy.downloadermiddlewares.redirect.MetaRefreshMiddleware', 'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware', 'scrapy.downloadermiddlewares.redirect.RedirectMiddleware', 'scrapy.downloadermiddlewares.stats.DownloaderStats'] 2017-09-28 18:03:04 [scrapy.middleware] INFO: Enabled spider middlewares: ['scrapy.spidermiddlewares.httperror.HttpErrorMiddleware', 'scrapy.spidermiddlewares.offsite.OffsiteMiddleware', 'scrapy.spidermiddlewares.referer.RefererMiddleware', 'scrapy.spidermiddlewares.urllength.UrlLengthMiddleware', 'scrapy.spidermiddlewares.depth.DepthMiddleware'] 2017-09-28 18:03:04 [scrapy.middleware] INFO: Enabled item pipelines: ['Xiuxian.pipelines.MongoDBPipeline'] 2017-09-28 18:03:04 [scrapy.core.engine] INFO: Spider opened 2017-09-28 18:03:04 [scrapy.extensions.logstats] INFO: Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min) 2017-09-28 18:03:04 [scrapy.extensions.telnet] DEBUG: Telnet console listening on 127.0.0.1:6023 2017-09-28 18:03:05 [scrapy.core.engine] DEBUG: Crawled (200) <GET http://www.dianping.com/robots.txt> (referer: None) 2017-09-28 18:03:05 [scrapy.core.engine] DEBUG: Crawled (403) <GET http://www.dianping.com/shop/38212967> (referer: None) 2017-09-28 18:03:05 [scrapy.spidermiddlewares.httperror] INFO: Ignoring response <403 http://www.dianping.com/shop/38212967>: HTTP status code is not handled or not allowed 2017-09-28 18:03:05 [scrapy.core.engine] INFO: Closing spider (finished) 2017-09-28 18:03:05 [scrapy.statscollectors] INFO: Dumping Scrapy stats: {'downloader/request_bytes': 588, 'downloader/request_count': 2, 'downloader/request_method_count/GET': 2, 'downloader/response_bytes': 975, 'downloader/response_count': 2, 'downloader/response_status_count/200': 1, 'downloader/response_status_count/403': 1, 'finish_reason': 'finished', 'finish_time': datetime.datetime(2017, 9, 28, 10, 3, 5, 520099), 'httperror/response_ignored_count': 1, 'httperror/response_ignored_status_count/403': 1, 'log_count/DEBUG': 3, 'log_count/INFO': 8, 'response_received_count': 2, 'scheduler/dequeued': 1, 'scheduler/dequeued/memory': 1, 'scheduler/enqueued': 1, 'scheduler/enqueued/memory': 1, 'start_time': datetime.datetime(2017, 9, 28, 10, 3, 4, 947156)} 2017-09-28 18:03:05 [scrapy.core.engine] INFO: Spider closed (finished) @preke
