现在我想在这个网页上刮掉所有物品(iphone)的图像。首先我把图片的所有链接都解压出来,然后一个一个的发送请求到src,下载到文件夹'/phone/'。这是我的代码:
from pyspider.libs.base_handler import *
class Handler(BaseHandler):
crawl_config = {
}
@every(minutes=24 * 60)
def on_start(self):
print 'hi'
self.crawl('https://s.taobao.com/search?q=iphone&imgfile=&ie=utf8', callback=self.index_page, fetch_type='js')
#@config(age=10 * 24 * 60 * 60)
def index_page(self, response):
items = response.doc('.item').items()
for item in items:
imgurl = item('.J_ItemPic img').attr('.src')
if imgurl:
filename = item('.J_ItemPic.img').attr('.id')
self.crawl(imgurl, callback=self.scrape_photo, save={'filename': filename})
def save_photo(self, content, filename):
with open('phone/'+filename, 'wb') as f:
f.write(content)
def scrape_photo(self, response):
content = response.content
filename = response.save['filename']+'.jpg'
self.save_photo(content, filename)
它非常直观和简单。但是当我运行代码时,什么都没有发生,我只是在终端中收到了以下日志消息:
[I 160602 18:57:42 scheduler:664] restart task sk:on_start data:,on_start

我对这个问题几乎疯了。你能告诉我是什么问题,我该如何解决?提前致谢!
