折腾:
【已解决】PySpider中用Python代码爬取小花生app中绘本数据
期间,本地调试可以正常下载文件的,比如:
https://img.xiaohuasheng.cn/Audio/2022/20180912141716840.mp3
但是去PySpider中开始RUN
开始批量下载时,结果报错:
[E 190411 14:27:32 tornado_fetcher:212] [599] XiaohuashengApp:b35ca6788da24132245924cb4ec084c7

如图:
很是奇怪。

Why “on_start” and nothing happend? · Issue #208 · binux/pyspider

python爬虫 – crawl 连接网页超时,HTTP 599 – SegmentFault 思否

“百度 谷歌了N久都没找到解决方案,有的说DNS的,然而我这边校园网改了DNS就上不了网了,有说禁用IPV6的,同样没效果,绝望之际,打开QQ找了个pyspider的群,问老司机得知,加个代理就好… 遂顺手加了个翻墙代理(跟墙没关,只是刚好有翻墙的),马上可以
crawl_config = {
      ‘proxy’: ‘127.0.0.1:1080’
如果真是这个原因,那真是诡异了。。。
不对,估计是:
此处需要加上UA等参数?
去试试
python爬虫 – crawl 连接网页超时,HTTP 599 – SegmentFault 思否
加上:
connect_timeout = 50,
                   timeout = 200
参考自己的:
【记录】用PySpider去爬取scholastic的绘本书籍数据
和:
http://docs.pyspider.org/en/latest/apis/self.crawl/
“connect_timeout
timeout for initial connection in seconds. default: 20
timeout
maximum time in seconds to fetch the page. default: 120
retries
retry times while failed. default: 3”
用,都增加了5倍:
class Handler(BaseHandler):
    crawl_config = {
        "connect_timeout": 100,
        "timeout": 600,
        "retries": 15,
    }
结果
还没试之前,注意到:
after 120000 milliseconds with 1723300 out of 2343850 bytes
感觉是:
120秒,下载了 1723300/2343850=70%多,没下载完毕
所以报告超时了
所以估计此处增加时间,应该是有效果,至少是部分效果的。
所以去试试
貌似就可以正常继续下载了:
log可以输出正常,无错误:
下载到的文件:
没过几分钟又报错了:

不过从错误日志中看,还是没有下载完毕
->看来是网络速度太慢了
-》发起的下载请求太多了,网络慢,处理不过来,导致超时
-》那回头(用自家的Wifi)更快的100M的网络,试试,估计就可以正常下载了。
而此处由于下载错误太多,都暂停下载了:
此处感觉只是网络速度问题,而幸好不是之前的:
【未解决】PySpider批量爬取时出现各种出错:UnboundLocalError+HTTP 599+Operation timed out+IndexError
这种错误,否则就郁闷,就不好解决了。
此处刚发现,上面改了代码,但是更新上去了。
现在重新加上,试试效果,共爬取数据:
  • 50多MB:目前没出错
  • 70多MB:没出错,但是像卡住不继续了
  • 100MB:没出错,不够速度是很慢
  • 600多MB:很慢。
算了,还是暂停,回家用家里快的网络下载吧。
这个下载的太慢了。
回到家,用10MB/s的网络下载:
速度不错:
继续下载看看吧。
不错,一直没出错:
然后知道最后,就下载好了。
不过后续发现有些缺失:
【未解决】PySpider看似下载完成但是部分图片资源没有下载
