pycurl的一些example

直接在github上找

basicfirst.py：

#! /usr/bin/env python
# -*- coding: utf-8 -*-
# vi:ts=4:et
import sys
import pycurl

PY3 = sys.version_info[0] > 2


class Test:
    def __init__(self):
        self.contents = ''
        if PY3:
            self.contents = self.contents.encode('ascii')

    def body_callback(self, buf):
        self.contents = self.contents + buf


sys.stderr.write("Testing %s\n" % pycurl.version)

t = Test()
c = pycurl.Curl()
c.setopt(c.URL, 'https://curl.haxx.se/dev/')
c.setopt(c.WRITEFUNCTION, t.body_callback)
c.perform()
c.close()

print(t.contents)

xmlrpc_curl.py：

#! /usr/bin/env python

# We should ignore SIGPIPE when using pycurl.NOSIGNAL - see
# the libcurl tutorial for more info.
try:
    import signal
    signal.signal(signal.SIGPIPE, signal.SIG_IGN)
except ImportError:
    pass
try:

except ImportError:
    try:

    """Handles a cURL HTTP transaction to an XML-RPC server."""

    xmlrpc_h = [ "Content-Type: text/xml" ]

    def __init__(self, username=None, password=None):
        self.c = pycurl.Curl()
        self.c.setopt(pycurl.POST, 1)
        self.c.setopt(pycurl.NOSIGNAL, 1)
        self.c.setopt(pycurl.CONNECTTIMEOUT, 30)
        self.c.setopt(pycurl.HTTPHEADER, self.xmlrpc_h)
        if username != None and password != None:

if __name__ == "__main__":
    ## Test
    server = xmlrpclib.ServerProxy("http://betty.userland.com",
                                   transport=CURLTransport())

D:\python\pycurl-master\tests里的post_test.py有一段可以参考：

def check_post(self, send, expect, endpoint):
        self.curl.setopt(pycurl.URL, endpoint)
        self.curl.setopt(pycurl.HTTPPOST, send)
        #self.curl.setopt(pycurl.VERBOSE, 1)
        sio = util.BytesIO()
        self.curl.setopt(pycurl.WRITEFUNCTION, sio.write)
        self.curl.perform()
        self.assertEqual(200, self.curl.getinfo(pycurl.HTTP_CODE))
        body = sio.getvalue().decode()
        returned_fields = json.loads(body)
        self.assertEqual(expect, returned_fields)

网上有一个利用pycurl上传文件的例子，胜在简洁，因此记录下来：

# -*- coding: utf-8 -*-  
import pycurl  
import os  
def upload(filename):  
    pc = pycurl.Curl()  
    pc.setopt(pycurl.POST, 1)  
    pc.setopt(pycurl.URL, 'your url')  
    pc.setopt(pycurl.HTTPPOST, [('file fieldname', (pc.FORM_FILE, filename)),\   
                              ('filed1_name', (pc.FORM_CONTENTS, "value"))])  
  
    pc.perform()  
    response_code = pc.getinfo(pycurl.RESPONSE_CODE)  
    pc.close()  
  
if __name__ == "__main__":  
    filelist = os.listdir(".")  
    for f in filelist:  
            upload(f)  
    print "OK"
