我如何解析这个字符串来获得链接
下面是相关功能的列表
module Fletcher
module Model
class Amazon < Fletcher::Model::Base
# A regular expression for determining if a url comes from a specific service/website
def self.regexp
/amazon\.com/
end
# Parse data and look for object attributes to give to object
def parse(data)
super(data)
case doc
when Nokogiri::HTML::Document
# Get Name
self.name = doc.css("h1.parseasinTitle").first_string
# Get Description
self.description = doc.css("div#productDescriptionWrapper").first_string
# Get description from meta title if not found
self.description = doc.xpath("//meta[@name='description']/@content").first_string if description.nil?
# Get Price
parse_price(doc.css("b.priceLarge").first_string)
# Get Images
self.images = doc.xpath("//table[@class='productImageGrid']//img").attribute_array
self.image = images.first
end
end
end
end
end
你的字符串看起来很像是调用'Ruby对象上inspect'的输出;你有实际的物体吗? –
@AndrewMarshall我不完全确定你指的是什么“实际”的对象。整个宝石(fletcher)在github上。 https://github.com/hulihanapplications/fletcher。我已经包含了上面的类和方法。 –
那么,你是如何得到这个字符串的? –
