【问题描述】:
嗨,我正在尝试在 scrapy spider 命令中传递参数列表。我能够为 1 个参数运行它。但无法为参数列表执行此操作。请帮忙。这是我尝试过的。
# -*- coding: utf-8 -*-
import scrapy
import json
class AirbnbweatherSpider(scrapy.Spider):
name = 'airbnbweather'
allowed_domains = ['www.wunderground.com']
def __init__(self,geocode ):
self.geocode = geocode.split(',')
pass
def start_requests(self):
yield scrapy.Request(url="https://api.weather.com/v3/wx/forecast/daily/10day?apiKey=6532d6454b8aa370768e63d6ba5a832e&geocode={0}{1}{2}&units=e&language=en-US&format=json".format(self.geocode[0],"%2C",self.geocode[1]))
def parse(self, response):
resuturant = json.loads(response.body)
yield {
'temperatureMax' : resuturant.get('temperatureMax'),
'temperatureMin' : resuturant.get('temperatureMin'),
'validTimeLocal' : resuturant.get('validTimeLocal'),
}
我可以使用这个命令来运行它
scrapy crawl airbnbweather -o BOSTON.json -a geocode="42.361","-71.057"
它工作正常。但是我如何遍历地理编码列表?
list = [("42.361","-71.057"),("29.384","-94.903"),("30.384", "-84.903")]
