import httplib
import uuid
import time

url = "/KM/test.php?time="
url += str(int(time.time()))
url += "&token="
url += uuid.uuid4().hex

print url

conn = httplib.HTTPConnection("a.bbbb.net:8008")

headerdata = {"Host":"a.bbbb.net:8008",
"Connection":"Keep-Alive",
"Accept-Encoding":"gzip"
}

conn.request(method="GET",url=url,body=None,headers = headerdata)

response = conn.getresponse()
res= response.read()
print res

import httplib, urllib

httpClient = None
try:
params = urllib.urlencode({'name': 'tom', 'age': 22})
headers = {"Content-type": "application/x-www-form-urlencoded"
, "Accept": "text/plain"}

httpClient = httplib.HTTPConnection("localhost", 80, timeout=30)
httpClient.request("POST", "/test.php", params, headers)

response = httpClient.getresponse()
print response.status
print response.reason
print response.read()
print response.getheaders() #获取头信息
except Exception, e:
print e
finally:
if httpClient:
httpClient.close()
