上次是wxWidget,这次又发现一个cURL。python版本分别叫做wxPython和pycurl。
wxWidget并不能算是一个特别牛的库,至少接口设计上还是MFC级别的,对xml也没有能用的支持,拼个界面很累。但是你猜不到的是,就这么烂的接口,用Python写出来的程序依然不长。
还有人用Python写Win32的窗口程序,也不长。
今天用到个libcurl,把C++版的测试代码和Python版本贴出来对比一下。
import pycurl import StringIO url = "http://www.google.com/" crl = pycurl.Curl() crl.setopt(pycurl.VERBOSE,1) crl.setopt(pycurl.FOLLOWLOCATION, 1) crl.setopt(pycurl.MAXREDIRS, 5) crl.fp = StringIO.StringIO() crl.setopt(pycurl.URL, url) crl.setopt(crl.WRITEFUNCTION, crl.fp.write) crl.perform() print crl.fp.getvalue()
