Using a Proxy with urllib2
When working with urllib2, there are situations where you may need to connect to the internet through a proxy server. Here's how you can use urllib2 to establish such a connection:
Question:
I want to open URLs using urllib2 with a proxy. I've tried using the following:
<code class="python">site = urllib2.urlopen('http://google.com', proxies={'http':'127.0.0.1'})</code>
but it doesn't seem to work. Is there a specific function I need to use to configure the proxy?
Answer:
To use a proxy with urllib2, you can follow these steps:
- Create a ProxyHandler object and specify the desired proxy settings:
<code class="python">proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})</code>
- Create an Opener object using the ProxyHandler:
<code class="python">opener = urllib2.build_opener(proxy)</code>
- Install the opener as the default opener for urllib2:
<code class="python">urllib2.install_opener(opener)</code>
- Use the installed opener to open the URL:
<code class="python">urllib2.urlopen('http://www.google.com')</code>
By following these steps, you can configure urllib2 to use the specified proxy server when making requests.
