【未解决】PySpider中给crawl加fetch_type为js后内部调用phantomjs结果导致大量出错:HTTP 599 Connection timed out after 20000 milliseconds 20.00s

折腾:

【未解决】pyspider运行出错:FETCH_ERROR HTTP 599 Connection timed out after milliseconds

期间,通过:

pyspider HTTP 599 Connection timed out after

难道是需要加user-agent?

答复: 问题:HTTP 599: Operation timed out… – Google Groups

“和 phantomjs 连接超时,看看 phantomjs 是否存活,还有没有响应。”

难道此处是和phantomjs有关系?

毕竟有些页面好像的确是:

给self.crawl加了fetch_type=‘js’后,用到了phantomjs后,加载速度是慢了

-》但是调试期间是可以正常加载的

-〉难道是此处run时,大规模访问,则会导致phantomjs出错?连接超时?加载页面超时?

“和 https://github.com/binux/pyspider/issues/213 类似,可能与 phantomjs 的负载有关。

当 phantomjs 负载高时,可能会出现一定比例的失败

如果你会改代码的话,可以尝试将

pyspider/fetcher/tornado_fetcher.py

> request_conf[‘request_timeout’] = fetch[‘timeout’] + 1

+更长的时间(比如10秒),以等待 phantomjs 返回。看失败率是否有改善”

感觉最大可能就是phantomjs的问题了。

要么去找到根本解决办法

要么去试试给phantomjs的超时时间加长试试

crawl 连接网页超时,HTTP 599 – sandiegoxu的回答 – SegmentFault 思否

不管了,去设置大点的超时时间

先去看看默认超时时间

self.crawl – pyspider

“connect_timeout

timeout for initial connection in seconds. default: 20

timeout

maximum time in seconds to fetch the page. default: 120”

<code>self.crawl(eachModelDetailDict["url"],
           callback=self.carModelSpecPage,
           fetch_type='js',
           retries=5,
           connect_timeout=50,
           timeout=300,
           save=curSerieDict)
</code>

结果:

问题依旧:

不过前面出错的log中,估计都是还没到最大的5次retry,对应着webui中没有出错:

所以可以继续运行,等待足够长时间,看看是否有fail的

不过看results中是有

1. FETCH_ERROR autohomeBrandData > https://www.autohome.com.cn/spec/10499/#pvareaid=2042128 3 minutes ago 28062.6+1.85ms +0

不过发现了,是很多retry

all里面是没有错的:

算了,跑了一夜,但是中间不知道为何出现Print打印的弹框,导致执行被暂停,搞得没继续执行。现在继续,也还是出现error的log。

算了,中断,下次重新运行。

然后注意到此前出错的也是:

不过增大timeout后,好像错误变成了

好像是:之前运行:

<code>pyspider -c config.json

忘了加all参数。

或许是这个问题?导致没有加载phantomjs?

不过从:

看到好像说是要手动指定phantomjs的端口的?

估计是之前帖子2015年的,太老了,新的是不需要指定phantomjs的port的?

此处记录一下最开始的输出:

其中是有:

phantomjs fetcher running on port 25555

然后没有all参数的输出:

<code>➜  AutocarData pyspider -c config.json

</code>

即:

pyspider没有指定模式时,默认也是all

-》加不加all,都没关系,phantomjs都会运行的

再去换个更快的公司的网络,去运行试试,看看是否出错

结果错误依旧:

<code>[E 180517 09:32:53 tornado_fetcher:212] [599] autohomeBrandData:29ae096711906a0100db8641da85ee6f https://www.autohome.com.cn/spec/29931/#pvareaid=2042128, HTTP 599: Connection timed out after 61314 milliseconds 62.30s

</code>

可以看出,此处时超时60多秒了,还是连接出错

所以,看起来不是简单的继续增加超时时间能解决的了

然后,也是部分时候,phantomjs是正常工作的,所以才能正常保存数据:

msrp值不为0:

说明此处代码的确执行到了:

<code>
        self.crawl(eachModelDetailDict["url"],
                   callback=self.carModelSpecPage,
                   fetch_type='js',
                   retries=5,
                   connect_timeout=50,
                   timeout=300,
                   save=curSerieDict)

@catch_status_code_error
def carModelSpecPage(self, response):
</code>

所以,真的是搞不懂为何出错了,以及如何彻底解决此问题。

mac中去看看进程:

<code>➜  ~ lsof -i:25555

也是有phantomjs在运行的

有30个python3.6进程

有31个phantomjs进程

应该都使用的了才对

停止了pyspider后,进程没了:

<code>➜  ~ lsof -i:25555

也是期望的现象。

去加上user-agent试试

继续运行看看是否会出错

不过可以看到,很多页面执行很慢,慢的有30多秒才执行完毕的,的确够慢的

去看内存发现:

phantomjs占用了1G多的内存

且pyspider已经被我中断停止运行了,结果竟然phantojs还有输出

所以很明显是:

部分页面是超过了self.crawl传递的connect_timeout=50的50秒超时设置,而超时了。

去搞清楚:

【已解决】pyspider中phantomjs中的proxy是什么意思

【未解决】pyspider中如何给phantomjs传递额外参数

貌似解决了参数传递,那继续去运行看看

<code>➜  AutocarData cat config.json
{
  "resultdb":   "mysql+resultdb://root:crifan_mysql@127.0.0.1:3306/AutohomeResultdb",
  "result_worker":{
      "result_cls": "AutohomeResultWorker.AutohomeResultWorker"
   },
  "phantomjs-proxy": "127.0.0.1:23450",
  "phantomjs" : {
    "port": 23450,
    "auto-restart": true,
    "load-images": false,
    "debug": true
  }
}%                                                                                                                                                            ➜  AutocarData pyspider -c config.json phantomjs
phantomjs fetcher running on port 23450

</code>

另外终端再去试试

<code>  AutocarData pyspider -c config.json all

</code>

等看后续是否还会出错

现在希望是:把load-images为false传递给了phantomjs了,这样加载页面但是不加载图片,希望减少出错的概率,减少页面加载时间,这样或许就不会超时?

虽然phantomjs可以执行一些页面:

结果还是出错了:

<code>[E 180517 22:19:57 tornado_fetcher:212] [599] autohomeBrandData:b0ccf36b6fc5473ee7d3742d33e1fa4f https://www.autohome.com.cn/spec/6726/#pvareaid=2042128, HTTP 599: Failed to connect to 127.0.0.1 port 23450: Operation timed out 27.83s

</code>

始终无法完全的彻底的解决这个问题。

【总结】

此处,为了想要获取页面中的部分的数据(比如某个车辆的价格),但是该数据是js内部异步加载的

而PySpider中的解决方案是:

给self.crawl加了fetch_type=‘js’ -》

内部用到了phantomjs,去调用js加载页面内容

此方案(在调试期间)是基本可用的。

但是,在运行PySpider后,大批量去爬取时,导致每个页面的加载时间都很长:

之前单个页面不到1秒,用了phantomjs后,每个页面都要2,3秒,甚至几十秒

以至于大量爬取页面时出错:

<code>tornado_fetcher HTTP 599: Connection timed out after 20000 milliseconds 20.00s
</code>

或者:

<code>tornado_fetcher HTTP 599: Failed to connect to 127.0.0.1 port 23450: Operation timed out 27.83s
</code>

先后试了多种方案:

  • 加大timeout时间

  • 换个更快的网络

  • 给pyspider加all参数

  • 想要给phantomjs加额外参数:未果

  • 猜测可能是phantomjs有内存泄漏的bug:不确定,也无法解决

  • 加了User-Agent

  • 等等等等

都无法解决。

目前只能放弃使用phantomjs了。
