curl on app engine

Question

can curl be used on google app engine ?

Answer 1

No. To make HTTP requests, you need to use the urlfetch service.

urllib, urllib2, and httplib on App Engine are patched to transparently use this API for you, so any third-party module that does HTTP requests using one of these standard modules will work.

The 'c' in cURL is there because the library is written in C; cURL interfaces in other languages (like pycurl) use the libcurl library, and can't be use on App Engine, as modules that reply on C extensions are not allowed.

Answer 2

I would recommand using the URL fetch service. For example in python

from google.appengine.api import urlfetch

url = "http://www.google.com/"
result = urlfetch.fetch(url)
if result.status_code == 200:
  doSomethingWithResult(result.content)

Answer 3

The answers to this are a bit dated. cURL totally works on GAE now. We are using it a number of places in our PHP application that is hosted on GAE.

Answer 4

Take a look at Twitter4J http://twitter4j.org/en/index.html - specifically mentions App Engine support.

Answer 5

It's a real old question and I end up here, so someone else might as well.

App Egine supports cURL requests.
