请求：未找到连接适配器，错误 Python3

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、link 等附加到此列表。但是当我尝试请求 link:

时出现错误

第一个link成功。但是第二个出了一个错误。我无法添加内容以列出此错误的原因。我的循环有问题吗？代码有什么问题？

Answer 1

如果你在有问题的行 r = requests.get(item.text) 之前添加行 print(repr(item.text)) 你会看到第二次开始 item.text 的开头和结尾有 \n URL.

不允许

'\nhttp://www.milliyet.com.tr/tbmm-baskani-cicek-programlarini/siyaset/detay/2037301/default.htm\n'

我使用 repr 因为它在输出中将换行字面显示为字符串 \n。

您的问题的解决方案是在 item.text 上调用 strip 以删除那些换行符：

r = requests.get(item.text.strip())
