乱七八糟的编码问题刮出引号

Question

我上这个班：

class PitchforkTracks(scrapy.Spider):
    name = "pitchfork_tracks"
    allowed_domains = ["pitchfork.com"]
    start_urls = [
                    "http://pitchfork.com/reviews/best/tracks/?page=1",
                    "http://pitchfork.com/reviews/best/tracks/?page=2",
                    "http://pitchfork.com/reviews/best/tracks/?page=3",
                    "http://pitchfork.com/reviews/best/tracks/?page=4",
                    "http://pitchfork.com/reviews/best/tracks/?page=5",
    ]
    def parse(self, response):

        for sel in response.xpath('//div[@class="track-details"]/div[@class="row"]'):
            item = PitchforkItem()
            item['artist'] = sel.xpath('.//li/text()').extract_first()  
            item['track'] = sel.xpath('.//h2[@class="title"]/text()').extract_first()  
            yield item

正在刮取此项目：

^{pr2}$

然而，结果打印如下：

{'artist': u'The Avalanches', 'track': u'\u201cColours\u201d'}

我在哪里和如何去掉quotes，即\u201c和{}？在

Answer 1

在parse(self, response)内，添加：

item['track'] = sel.xpath('.//h2[@class="title"]/text()').extract_first().strip(u'\u201c\u201d')
