scrapy 从 txt 文件读取 url 失败

Question

This is how the txt file looks like, and I opened it from jupiter notebook. Notice that I changed the name of the links in the result for obvious reason. input-----------------------------

with open('...\j.txt', 'r')as f: data = f.readlines()

print(data[0]) print(type(data))

output---------------------------------

[' https://www.example.com/191186976.html ', ' https://www.example.com/191187171.html ']

Now I wrote these in my scrapy script, it didn't go for the links when I ran it. Instead it shows: ERROR: Error while obtaining start requests.

class abc(scrapy.Spider): name = "abc_article"

with open('j.txt' ,'r')as f4:
    url_c = f4.readlines()

u = url_c[0]    
start_urls = u

And if I wrote u = ['example.html', 'example.html'] starting_url = u then it works perfectly fine. I'm new to scrapy so I'd like to ask what is the problem here? Is it the reading method or something else I didn't notice. Thanks.

Something like this should get you going in the right direction.

import csv
from urllib.request import urlopen
#import urllib2
from bs4 import BeautifulSoup

contents = []
with open('C:\\your_path_here\\test.csv','r') as csvf: # Open file in read mode
    urls = csv.reader(csvf)
    for url in urls:
        contents.append(url) # Add each url to list contents

for url in contents:  # Parse through each url in the list.
    page = urlopen(url[0]).read()
    soup = BeautifulSoup(page, "html.parser")
print(soup)
