Description: a python interface into curl just came out and I have never heard of CURL. could be cool to wrap a class around it and manipulate returned data in a bit more sensible way. MUST: * install curl - http://curl.haxx.se/ * install pycurl - http://pycurl.sourceforge.net/ * make sure you can see pycurl form python interpreter running ZOPE |

Source (Text): #create a file in zope/Extensions calledd, useCURL.py
import curl
import tempfile
def useCURL(uri='dict://dict.org/d:zope'):
f = tempfile.TemporaryFile()
ret = ""
_curl = curl.init()
_curl.setopt(curl.URL, uri)
_curl.setopt(curl.FILE, f)
_curl.setopt(curl.NOPROGRESS, 1)
_curl.setopt(curl.FOLLOWLOCATION, 1)
_curl.setopt(curl.MAXREDIRS, 5)
_curl.perform()
_curl.cleanup()
f.seek(0)
for l in f.readlines():
ret = ret + l
f.close()
return ret
# create a External Method called useCURL
# id - getURI, module- useCURL, function - useCURL
# inside a dtml method
<pre>
<dtml-var "getURI(uri='dict://dict.org/d:zope')">
</pre>

Explanation: this is really a silly example of a fast way of exposing a python library into Zope ala External Methods. But as easy as it is to hook CURL into ZOPE you can hook any other python library. |
