Question

import requests
import xml.etree.ElementTree as ET
import re

gen_news_list=[]
r_milligenel = requests.get('http://www.milliyet.com.tr/D/rss/rss/Rss_4.xml')
root_milligenel = ET.fromstring(r_milligenel.text)

for entry in root_milligenel:
    for channel in entry:
        for item in channel:
            title = re.search(".*title.*",item.tag)
            if title:
                gen_news_list.append(item.text)
            link = re.search(".*link.*",item.tag)
            if link:
                gen_news_list.append(item.text)
                r = requests.get(item.text)
                print(r.text)

我有一个名为gen_news_list的列表，我正在尝试将标题，摘要，链接等附加到此列表中。但是当我尝试请求链接时出现错误：

第一个链接成功运行。但第二个出错了。我无法添加内容以列出此错误的原因。这是我的循环问题吗？代码有什么问题？

Answer 1

如果您在有问题的行print(repr(item.text))之前添加行r = requests.get(item.text)，您会看到第二次item.text开始时\n开头有'\nhttp://www.milliyet.com.tr/tbmm-baskani-cicek-programlarini/siyaset/detay/2037301/default.htm\n'而不允许用于URL。

\n

我使用repr因为它在输出中将换行字面显示为字符串item.text。

问题的解决方案是致电r = requests.get(item.text.strip())上的strip以删除这些换行符：
