没有找到 Python3-Requests 的连接适配器

Question

我在 python3 中使用带有请求包的漂亮汤来进行网页抓取。这是我的代码。

import csv  
from datetime import datetime
import requests
import csv  
from datetime import datetime 
from bs4 import BeautifulSoup


quote_page = ['http://10.69.161.179:8080'];

data = []

page = requests.get(quote_page)

soup = BeautifulSoup(page.content,'html.parser')

name_box = soup.find('div', attrs={'class':'caption span10'})

name= name_box.text.strip() #strip() is used to remove starting and ending

print(name);

data.append(name)

    

with open('sample.csv', 'a') as csv_file:  
    writer = csv.writer(csv_file)
    writer.writerow([name])

print ("Success");

当我执行上述代码时，出现以下错误。

Traceback (most recent call last):
  File "first_try.py", line 21, in <module>
    page = requests.get(quote_page);
  File "C:\Python\lib\site-packages\requests-2.13.0-py3.6.egg\requests\api.py", line 70, in get
    return request('get', url, params=params, **kwargs)

    resp = self.send(prep, **send_kwargs)

    adapter = self.get_adapter(url=request.url)
  File "C:\Python\lib\site-packages\requests-2.13.0-py3.6.egg\requests\sessions.py", line 685, in get_adapter
    raise InvalidSchema("No connection adapters were found for '%s'" % url)
requests.exceptions.InvalidSchema: No connection adapters were found for '['http://10.69.161.179:8080/#/main/dashboard/metrics']'

谁能帮我这个？:(

Answer 1

因为 requests.get() 只接受字符串格式的 url 模式。您需要在列表 [] 中解压字符串。

quote_page = ['http://10.69.161.179:8080']
for url in quote_page:
  page = requests.get(url)
  .....

顺便说一句，虽然分号在以下语句中是无害的，但除非出于某种原因需要它，否则您应该避免使用它

quote_page = ['http://10.69.161.179:8080'];
