CrawlSpider爬图片的时候遇到了不完整url

狗宁

这是部分代码

class BizhiSpider(CrawlSpider):
    name = 'bizhi'
    # allowed_domains = ['www.xxxx.com']
    start_urls = ['http://www.netbian.com/weimei/']
    start_link = LinkExtractor(allow='index_\d+?.htm')
    detail_link = LinkExtractor(allow='desk.+?\.htm')
    link = []
    detail=[]
    for each in start_link:
        each = 'http://www.netbian.com/' + each
        link.append(each)
    for url in detail_link:
        url = 'http://www.netbian.com/' + url
        detail.append(url)
     #对页码url进行解析
    rules = (
        Rule(link, callback='parse_item', follow=False),
        Rule(detail,callback=detail_parse,follow=True)
    )
    #页码解析函数
    def parse_item(self, response):
        pass
        # li_list = response.xpath('//*[@id="main"]/div[2]/ul/li')
        # item = QuanzhanproItem()
        # for li in li_list:
        #     img_name = li.xpath('./a/@title').extract_first()
        #     item['img_name'] = img_name

    def detail_parse(self,response):
        src = response.xpath('//*[@id="main"]/div[2]/div/p/a/img/@src').extract_first()
        item = QuanzhanproItem()
        item['src'] = src
        yield item

在用链接提取器后提取到了不完整的url，我以为可以迭代然后拼接，可是报错了，问一下有没有比较ok的解决办法？？

解决了 ，自己想多了，这个LinkExtractor会自动解析当前主域名然后拼接，希望能帮到你们
