How to crawl an entire website with Scrapy?

Question

I\'m unable to crawl a whole website, Scrapy just crawls at the surface, I want to crawl deeper. Been googling for the last 5-6 hours and no help. My code below:

Answer 1

When parsing the start_urls, deeper urls can be parsed by the tag href. Then, deeper request can be yielded in the function parse(). Here is a simple example. The most important source code is shown below:

from scrapy.spiders import Spider
from tutsplus.items import TutsplusItem
from scrapy.http    import Request
import re

class MySpider(Spider):
    name            = "tutsplus"
    allowed_domains = ["code.tutsplus.com"]
    start_urls      = ["http://code.tutsplus.com/"]

    def parse(self, response):
        links = response.xpath('//a/@href').extract()

        # We stored already crawled links in this list
        crawledLinks = []

        # Pattern to check proper link
        # I only want to get tutorial posts
        linkPattern = re.compile("^\/tutorials\?page=\d+")

        for link in links:
        # If it is a proper link and is not checked yet, yield it to the Spider
            if linkPattern.match(link) and not link in crawledLinks:
                link = "http://code.tutsplus.com" + link
                crawledLinks.append(link)
                yield Request(link, self.parse)

        titles = response.xpath('//a[contains(@class, "posts__post-title")]/h1/text()').extract()
        for title in titles:
            item = TutsplusItem()
            item["title"] = title
            yield item
