用Python的scrapy写了一个从网页下图片的爬虫，报错：Missing scheme in request url: h
去百度了也google了都说是相对地址不完整要搞成绝对地址，我用urljoin试了没用，直接用完整的图片地址也没有用。
求大神帮助。
[code=python]import scrapy
from imageSpider.items import ImagespiderItem
class image_Spider(scrapy.Spider):
name="imgSpider"
allowed_domains=["image.baidu.com"]
start_urls=["http://image.baidu.com/"]
def parse(self,response):
oriList=response.xpath('//div[@class="img_pic_wrap_layer"]/img/@src').extract()
for each in oriList:
each=response.urljoin(each)
item=ImagespiderItem()
item['image_urls']=each
yield item[/code]
