嗨夥計我已經寫在python刮履帶......使用基於Python scrapy履帶但得到錯誤
import scrapy
from c2.items import C2Item
try:
class C2(scrapy.Spider):
name = 'cn'
allowed_domains = ['priceraja.com']
start_urls = ['https://www.priceraja.com']
def parse_item(self, response):
Item = []
Item['url']=response.xpath('//a/@href/text()').extract()
yield Item
except Exception:
logging.exception("message")
我不斷獲取NotImplemented錯誤
