我正在使用scrapy抓取網(wǎng)站，但收到 429 響應(yīng)。下面是它的輸出日志：2020-06-06 21:39:45 [scrapy.core.engine] INFO: Spider openedINFO:scrapy.extensions.logstats:Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min)2020-06-06 21:39:45 [scrapy.extensions.logstats] INFO: Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min)INFO:scrapy.extensions.telnet:Telnet console listening on 127.0.0.1:60232020-06-06 21:39:45 [scrapy.extensions.telnet] INFO: Telnet console listening on 127.0.0.1:6023DEBUG:scrapy.core.engine:Crawled (429) <GET https://www.realestate.com.au/rent/in-aspendale+gardens,+vic+3195/list-1> (referer: None)2020-06-06 21:39:46 [scrapy.core.engine] DEBUG: Crawled (429) <GET https://www.realestate.com.au/rent/in-aspendale+gardens,+vic+3195/list-1> (referer: None)INFO:scrapy.spidermiddlewares.httperror:Ignoring response <429 https://www.realestate.com.au/rent/in-aspendale+gardens,+vic+3195/list-1>: HTTP status code is not handled or not allowed2020-06-06 21:39:46 [scrapy.spidermiddlewares.httperror] INFO: Ignoring response <429 https://www.realestate.com.au/rent/in-aspendale+gardens,+vic+3195/list-1>: HTTP status code is not handled or not allowedINFO:scrapy.core.engine:Closing spider (finished)2020-06-06 21:39:46 [scrapy.core.engine] INFO: Closing spider (finished)INFO:scrapy.statscollectors:Dumping Scrapy stats:{'downloader/request_bytes': 343, 'downloader/request_count': 1, 'downloader/request_method_count/GET': 1, 'downloader/response_bytes': 2030, 'downloader/response_count': 1, 'downloader/response_status_count/429': 1, 'finish_reason': 'finished', 'finish_time': datetime.datetime(2020, 6, 6, 11, 39, 46, 255540), 'httperror/response_ignored_count': 1, 'httperror/response_ignored_status_count/429': 1, 'log_count/DEBUG': 1, 'log_count/INFO': 10, 'memusage/max': 50941952, 'memusage/startup': 50941952, 'response_received_count': 1, 'scheduler/dequeued': 1,你可以看到downloader/request_count只有 1。

狀態(tài)代碼429表示連接過(guò)多。下載器上的請(qǐng)求計(jì)數(shù)為 1，因?yàn)?429 表示拒絕并且不會(huì)通過(guò)下載器。他們錯(cuò)誤地向他們認(rèn)為是機(jī)器人的任何請(qǐng)求提供 429 代碼。
經(jīng)過(guò)實(shí)驗(yàn)后，由于缺少 cookie 標(biāo)頭，它拒絕了我，該 cookie 標(biāo)頭是在 set-cookie 標(biāo)頭的初始 GET 請(qǐng)求中設(shè)置的。這里有一些嘗試將 Selenium 作為任何抓取項(xiàng)目中的最后一個(gè)選項(xiàng)。
嘗試使用像下面這樣的完整標(biāo)題和COOKIES_ENABLED = True.
