我正在從網站上下載電子郵件地址。 我有一個簡單的Scrapy抓取工具,它將一個.txt文件與域相關聯,然後通過抓取它們來查找電子郵件地址。Scrapy - 意外的後綴「%0A」鏈接
不幸的是,Scrapy正在鏈接中添加後綴「%0A」。你可以在日誌文件中看到它。
這裏是我的代碼:
class EmailsearcherSpider(scrapy.Spider):
name = 'emailsearcher'
allowed_domains = []
start_urls = []
unique_data = set()
def __init__(self):
for line in open('/home/*****/domains',
'r').readlines():
self.allowed_domains.append(line)
self.start_urls.append('http://{}'.format(line))
def parse(self, response):
emails = response.xpath('//body').re('([a-zA-Z0-9_.+-][email protected][a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+)')
for email in emails:
print(email)
print('\n')
if email and (email not in self.unique_data):
self.unique_data.add(email)
yield {'emails': email}
domains.txt:
link4.pl/kontakt
danone.pl/Kontakt
axadirect.pl/kontakt/dane-axa-direct.html
andrzejtucholski.pl/kontakt
premier.gov.pl/kontakt.html
這裏是原木控制檯:

請勿使用'readlines()';一個文件已經是一個迭代器,它可以讓你一次從文件中讀取一行。 – chepner
