我如何解决此错误：InvalidSchema（“未找到{！r}的连接适配器。” format（url））？

Question

我收到此错误：InvalidSchema（“未找到{！r}的连接适配器。”。format（url））

当我尝试运行此代码时：

import pandas as pd
pd.set_option('display.max_colwidth', -1)
url_file = 'https://github.com/MarissaFosse/ryersoncapstone/raw/master/DailyNewsArticles.xlsx'

tstar_articles = pd.read_excel(url_file, "TorontoStar Articles", header=0) 

url_to_sents = {}

for url in tstar_articles:
  url = tstar_articles['URL']
  page = requests.get(url)
  soup = BeautifulSoup(page.content, 'html.parser')
  results = soup.find(class_='c-article-body__content') 
  results_text = [tag.get_text().strip() for tag in results]
  sentence_list = [sentence for sentence in results_text if not '\n' in sentence]
  sentence_list = [sentence for sentence in sentence_list if '.' in sentence]
  article = ' '.join(sentence_list)
  url_to_sents[url] = article

我正在尝试使用request（）从我创建的Excel文件中读取URL。我怀疑这是由于看不见的字符引起的，但不知道如何检查。

更改：

for url in tstar_articles:
    url = tstar_articles['URL']
    page = requests.get(url)

至：

for url in tstar_articles['URL']:
    page = requests.get(url)
