我正在编辑旧的scrapy脚本。对于某些页面,“浴室”字段不存在。如果不存在,我要输入“ 0”。
我可以用熊猫发布进程,但是现在我想在scrapy脚本中实现。
我尝试了这个,但是出错了。
town.py”,第88行 其他: ^ SyntaxError:语法无效
bathrooms_txt = response.xpath(".//dt[contains(text(), 'Bathrooms')]/following-sibling::dd/text()").extract_first()
if bathrooms_txt == "":
bathrooms = "0"
else:
bathrooms = bathrooms_txt
except:
pass

您可能正在弄乱try语句。
您是不是要放:
bathrooms_txt = response.xpath(".//dt[contains(text(), 'Bathrooms')]/following-sibling::dd/text()").extract_first()
try:
if bathrooms_txt == "":
bathrooms = "0"
else:
bathrooms = bathrooms_txt
except:
pass

编辑piplines.py
import requests
with open("file.txt") as f:
for line in f:
user_id, email = line.split()
response = requests.post(
'https://companyname.jitbit.com/api/UpdateUser',
auth=('username', 'password'),
data=dict(
userId=user_id,
email=email,
),
)
print(response)

extract_first
方法具有default
自变量,您可以在这种情况下使用:
value = response.xpath("selector").extract_first(default="0")
或:
value = response.xpath("selector").extract_first("0")
