CH0101 a^b 【快速冪的兩類理解】

Django(建表,配置一些的就不說了):
class Jiayou(models.Model): # 建表以及欄位名
zxn_title = models.CharField(max_length=500)
zxn_brief = models.CharField(max_length=500)
zxn_date = models.CharField(max_length=500)
zxn_position = models.CharField(max_length=500)
zxn_category = models.CharField(max_length=500)
zxn_cnum = models.CharField(max_length=500)

class Meta:
    db_table = 'Jiayou'  # 表名

Django(views get請求程式碼):

class JiayouView(APIView):
def get(self, request):
zxn = models.Jiayou.objects.all() # 獲取表裡所有資料
data = JiayouSerializer(zxn, many=True) # 用序列化新增資料
return Response({ # 返回響應
"status": 200,
"msg": "",
"data": data.data
})

爬蟲scrapy框架(程式碼):
class KaoshiSpider(scrapy.Spider):
name = 'kaoshi'
start_urls = ['

http://www.mchotline.com/shuji/']

# print(start_urls)
def parse(self, response):
    set = response.xpath('.//div[@class="list bgb "]/ul/li')
    for list in set:
        zxn_title = list.xpath('./h2/a/text()').extract()[0]
        # print(zxn_title)
        zxn_brief = ''.join(list.xpath('./p/text()').extract())
        # print(zxn_brief)
        zxn_date = ''.join(list.xpath('./small/span[1]/text()').extract()).replace('\r', '').replace('\n', '').replace('勵志人生網', '')
        # print(zxn_date)
        zxn_position = ''.join(list.xpath('./small/span[2]/text()').extract()).replace('\r', '').replace('\n', '')
        # print(zxn_position)
        zxn_category = ''.join(list.xpath('./small/span[3]/a/text()').extract()).replace('\r', '').replace('\n','').replace('勵志人生網', '')
        print(zxn_category)
        zxn_cnum = ''.join(list.xpath('./small/span[4]/text()').extract()).replace('\r', '').replace('\n','').replace('勵志人生網', '')
        # print(category)

        yield YuekaoItem(zxn_title=zxn_title,zxn_brief=zxn_brief,zxn_date=zxn_date,zxn_position=zxn_position,zxn_category=zxn_category,zxn_cnum=zxn_cnum)
