网页爬虫 - python3 错误“No connection adapters were found for”

Question

python3 版本
检查连接的时候，出现错误“requests.exceptions.InvalidSchema: No connection adapters were found for 'http://oil.cngold.com.cn/2016...'”实在是不知道啥原因？很是奇怪
代码如下：

---

import requests
from bs4 import BeautifulSoup

filepath = 'E:/links.txt'
with open(filepath,'rb') as f:
    links = f.readlines()

for link in links:
    link = link.strip().decode()
    print(link)
    html = requests.get(link)
    soup = BeautifulSoup(html.text)
    print(soup.title.get_text())

报错信息如下：
