部署失败，因为多个蜘蛛使用Scrapinghub

我使用scrapy创建一个项目并将数据保存到我的mongodb。它可以工作。

这是我的代码：

# -*- coding: utf-8 -*-
import scrapy
from scrapy import Request
import time

# scrapy api imports
from scrapy.crawler import CrawlerProcess
from scrapy.utils.project import get_project_settings

# I import a lots of spider file here.
from Tainan.Madou import Madou
# from ... import ...
# from ... import ...

# Spider Array: add spider into array
CrawlersArray = [ Madou ] 

class MoviesSpider(scrapy.Spider):
    name = 'movies'
    allowed_domains = ['tw.movies.yahoo.com', 'movies.yahoo.com.tw']
    start_urls = ['http://tw.movies.yahoo.com/movie_thisweek.html/']


process = CrawlerProcess(get_project_settings())

for spider in CrawlersArray:
    process.crawl(spider)

process.start()

这是我的Madou蜘蛛，我有很多像Madou一样的蜘蛛，如果我不添加if __name__ == '__main__':我可以运行我所有的蜘蛛

        countLen += 1
        if countLen == dataLen:
            yield tainan

但是当我想将我的项目部署到Scrapinghub时，我收到了错误

Exceeded container timeout 60s

我从github找到解决方案 https://github.com/scrapinghub/shub/issues/273

我不确定如何使用第一个解决方案，所以我尝试第二个解决方案，就像提问者一样。

我修复了这样的代码：

if __name__ == '__main__':
    process = CrawlerProcess(get_project_settings())

    for spider in CrawlersArray:
        process.crawl(spider)

    process.start()

它可以将项目部署到Scrapinghub成功，但是当我运行项目时，我发现没有一个蜘蛛跑。

为什么？我无法弄清楚。

任何帮助将不胜感激。提前谢谢。

这是我运行项目时的终端信息：

答案 0 :(得分：1)

从日志中可以清楚地看到您错过了parse回调

class MoviesSpider(scrapy.Spider):
    name = 'movies'
    allowed_domains = ['tw.movies.yahoo.com', 'movies.yahoo.com.tw']
    start_urls = ['http://tw.movies.yahoo.com/movie_thisweek.html/']

    def parse(self, response):
        print("inside parse")

在解析回调函数中，您解析响应（网页）并返回带有提取数据的dicts，Item对象，Request对象或这些对象的可迭代对象。这些请求还将包含一个回调（可能相同），然后由Scrapy下载，然后由指定的回调处理它们的响应。
