What should I use to open a url instead of urlopen in urllib3

问题

I wanted to write a piece of code like the following:

from bs4 import BeautifulSoup
import urllib2

url = 'http://www.thefamouspeople.com/singers.php'
html = urllib2.urlopen(url)
soup = BeautifulSoup(html)

But I found that I have to install urllib3 package now.

Moreover, I couldn't find any tutorial or example to understand how to rewrite the above code, for example, urllib3 does not have urlopen.

Any explanation or example, please?!

P/S: I'm using python 3.4.

回答1:

urllib3 is a different library from urllib and urllib2. It has lots of additional features to the urllibs in the standard library, if you need them, things like re-using connections. The documentation is here: https://urllib3.readthedocs.org/

If you'd like to use urllib3, you'll need to pip install urllib3. A basic example looks like this:

from bs4 import BeautifulSoup
import urllib3

http = urllib3.PoolManager()

url = 'http://www.thefamouspeople.com/singers.php'
response = http.request('GET', url)
soup = BeautifulSoup(response.data)

回答2:

You do not have to install urllib3. You can choose any HTTP-request-making library that fits your needs and feed the response to BeautifulSoup. The choice is though usually requests because of the rich feature set and convenient API. You can install requests by entering pip install requests in the command line. Here is a basic example:

from bs4 import BeautifulSoup
import requests

url = "url"
response = requests.get(url)

soup = BeautifulSoup(response.content, "html.parser")

The new urllib3 library has a nice documentation here
In order to get your desired result you shuld follow that:

Import urllib3
from bs4 import BeautifulSoup

url = 'http://www.thefamouspeople.com/singers.php'

http = urllib3.PoolManager()
response = http.request('GET', url)
soup = BeautifulSoup(response.data.decode('utf-8'))

The "decode utf-8" part is optional. It worked without it when i tried, but i posted the option anyway.
