pycurl的一些example

直接在github上找

https://github.com/pycurl/pycurl/tree/master/examples

 

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 # -*- coding: utf-8 -*- # vi:ts=4:et # 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: from cStringIO import StringIO except ImportError: try: from StringIO import StringIO except ImportError: from io import StringIO try: import xmlrpclib except ImportError: import xmlrpc.client as xmlrpclib import pycurl import sys PY3 = sys.version_info[0] > 2


class CURLTransport(xmlrpclib.Transport): """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: self.c.setopt(pycurl.USERPWD, '%s:%s' % (username, password)) self._use_datetime = False  def request(self, host, handler, request_body, verbose=0): b = StringIO() self.c.setopt(pycurl.URL, 'http://%s%s' % (host, handler)) self.c.setopt(pycurl.POSTFIELDS, request_body) self.c.setopt(pycurl.WRITEFUNCTION, b.write) self.c.setopt(pycurl.VERBOSE, verbose) self.verbose = verbose try: self.c.perform() except pycurl.error: v = sys.exc_info()[1] if PY3: v = v.args raise xmlrpclib.ProtocolError( host + handler, v[0], v[1], None ) b.seek(0) return self.parse_response(b) if __name__ == "__main__": ## Test server = xmlrpclib.ServerProxy("http://betty.userland.com", transport=CURLTransport()) print(server) try: print(server.examples.getStateName(41)) except xmlrpclib.Error: v = sys.exc_info()[1] print("ERROR", v)

 

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

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)

 

網上有一個利用pycurl上傳文件的例子，勝在簡潔，因此記錄下來：

# -*- 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"
