Python Requests.Get-提供无效的架构错误

Question

另一个给你。

尝试从CSV文件中抓取网址列表。 这是我的代码：

from bs4 import BeautifulSoup
import requests
import csv

with open('TeamRankingsURLs.csv', newline='') as f_urls, open('TeamRankingsOutput.csv', 'w', newline='') as f_output:
    csv_urls = csv.reader(f_urls)
    csv_output = csv.writer(f_output)


    for line in csv_urls:
        page = requests.get(line[0]).text
        soup = BeautifulSoup(page, 'html.parser')
        results = soup.findAll('div', {'class' :'LineScoreCard__lineScoreColumnElement--1byQk'})

        for r in range(len(results)):
            csv_output.writerow([results[r].text])

...这给了我以下错误：

Traceback (most recent call last):
  File "TeamRankingsScraper.py", line 11, in <module>
    page = requests.get(line[0]).text
  File "C:\Users\windowshopr\AppData\Local\Programs\Python\Python36\lib\site-packages\requests\api.py", line 72, in get
    return request('get', url, params=params, **kwargs)
  File "C:\Users\windowshopr\AppData\Local\Programs\Python\Python36\lib\site-packages\requests\api.py", line 58, in request
    return session.request(method=method, url=url, **kwargs)
  File "C:\Users\windowshopr\AppData\Local\Programs\Python\Python36\lib\site-packages\requests\sessions.py", line 512, in request
    resp = self.send(prep, **send_kwargs)
  File "C:\Users\windowshopr\AppData\Local\Programs\Python\Python36\lib\site-packages\requests\sessions.py", line 616, in send
    adapter = self.get_adapter(url=request.url)
  File "C:\Users\windowshopr\AppData\Local\Programs\Python\Python36\lib\site-packages\requests\sessions.py", line 707, in get_adapter
    raise InvalidSchema("No connection adapters were found for '%s'" % url)
requests.exceptions.InvalidSchema: No connection adapters were found for 'https://www.teamrankings.com/mlb/stat/runs-per-game?date=2018-04-15'

我的CSV文件只是A列中几个网址的列表（即https：// www ..。 ）

（我要抓取的div类在该页面上不存在，但那不是问题所在。至少我不认为。我可以更新它，以便可以从CSV中读取它。文件。）

有什么建议么？ 因为此代码可在另一个项目上使用，但是由于某些原因，我在使用这个新的URL列表时遇到了问题。 非常感谢！

从追溯中， requests.exceptions.InvalidSchema: No connection adapters were found for 'https://www.teamrankings.com/mlb/stat/runs-per-game?date=2018-04-15'

请参阅网址中的随机字符，它应从https://www.teamrankings.com/mlb/stat/runs-per-game?date=2018-04-15开始

因此，首先使用regex解析csv并删除http / https之前的所有随机字符。 那应该解决您的问题。

如果您想在读取csv时使用此特定的网址解决当前的问题，请执行以下操作：

import regex as re

strin = "https://www.teamrankings.com/mlb/stat/runs-per-game?date=2018-04-15"

re.sub(r'.*http', 'http', strin)

这将为您提供请求可以处理的正确网址。

由于您要求对循环中可访问的路径进行全面修复，因此您可以执行以下操作：

from bs4 import BeautifulSoup
import requests
import csv
import regex as re

with open('TeamRankingsURLs.csv', newline='') as f_urls, open('TeamRankingsOutput.csv', 'w', newline='') as f_output:
    csv_urls = csv.reader(f_urls)
    csv_output = csv.writer(f_output)


    for line in csv_urls:
        page = re.sub(r'.*http', 'http', line[0])
        page = requests.get(page).text
        soup = BeautifulSoup(page, 'html.parser')
        results = soup.findAll('div', {'class' :'LineScoreCard__lineScoreColumnElement--1byQk'})

        for r in range(len(results)):
            csv_output.writerow([results[r].text])
