python http 长连接

 

#coding=UTF-8
import httplib

def url_open(conn_obj):
    """httplib长连接"""
    try:
        #GET方式
        conn_obj.request("GET", "/func?para=0", "", {"Connection":"Keep-Alive"})
        #POST方式
        #conn_obj.request("POST", "/func","param=0", {"Connection":"Keep-Alive"})
        response = conn_obj.getresponse()
        return response.read()
    except:
        return "error"

if __name__ == "__main__":
    conn = httplib.HTTPConnection("12.12.12.12:80")
    for i in range(100):
        print url_open(conn)
    conn.close()

 

HTTP 1.1协议headers中指定Keep-Alive就额可以了...

使用长连接这样就可以节省很多系统资源.
