1.1.4 Examples
|
|
</h2>
|
|
|
|
<p>
|
|
To do a simple <code>GET</code> request just supply the absolute URI
|
|
of the resource:
|
|
|
|
<p>
|
|
<div class="verbatim"><pre>
|
|
import httplib2
|
|
h = httplib2.Http()
|
|
resp, content = h.request("http://bitworking.org/")
|
|
assert resp.status == 200
|
|
assert resp['content-type'] == 'text/html'
|
|
</pre></div>
|
|
|
|
<p>
|
|
Here is more complex example that does a PUT
|
|
of some text to a resource that requires authentication.
|
|
The Http instance also uses a file cache
|
|
in the directory <code>.cache</code>.
|
|
|
|
<p>
|
|
<div class="verbatim"><pre>
|
|
import httplib2
|
|
h = httplib2.Http(".cache")
|
|
h.add_credentials('name', 'password')
|
|
resp, content = h.request("https://example.org/chap/2",
|
|
"PUT", body="This is text",
|
|
headers={'content-type':'text/plain'} )
|
|
</pre></div>
|
|
|
|
<p>
|
|
Here is an example that connects to a server that
|
|
supports the Atom Publishing Protocol.
|
|
|
|
<p>
|
|
<div class="verbatim"><pre>
|
|
import httplib2
|
|
h = httplib2.Http()
|
|
h.add_credentials(myname, mypasswd)
|
|
h.follow_all_redirects = True
|
|
headers = {'Content-Type': 'application/atom+xml'}
|
|
body = """<?xml version="1.0" ?>
|
|
<entry xmlns="http://www.w3.org/2005/Atom">
|
|
<title>Atom-Powered Robots Run Amok</title>
|
|

|
|
<content>Some text.</content>
|
|
</entry>
|
|
"""
|
|
uri = "http://www.example.com/collection/"
|
|
resp, content = h.request(uri, "POST", body=body, headers=headers)
|
|
</pre></div>
|
|
|
|
<p>
|
|
Here is an example of providing data to an HTML form processor.
|
|
In this case we presume this is a POST form. We need to take our
|
|
data and format it as "application/x-www-form-urlencoded" data and use that as a
|
|
body for a POST request.
|
|
|
|
<p>
|
|
<div class="verbatim"><pre>
|
|
>>> import httplib2
|
|
>>> import urllib
|
|
>>> data = {'name': 'fred', 'address': '123 shady lane'}
|
|
>>> body = urllib.urlencode(data)
|
|
>>> body
|
|
'name=fred&address=123+shady+lane'
|
|
>>> h = httplib2.Http()
|
|
>>> resp, content = h.request("http://example.com", method="POST", body=body)
|
|
</pre></div>
|
|
|
|
<p>
|
|
Here is an example of using a proxy server:
|
|
<div class="verbatim"><pre>
|
|
import httplib2
|
|
import socks
|
|
|
|
httplib2.debuglevel=4
|
|
h = httplib2.Http(proxy_info = httplib2.ProxyInfo(socks.PROXY_TYPE_HTTP, 'localhost', 8000))
|
|
r,c = h.request("http://bitworking.org/news/")
|
|
</pre></div>
