python --curl重定向到文件范例

import sys
import os
import subprocess
import time

start = time.time()
old=sys.stdout
f=open('testdata.log','w')
sys.stdout=f
p = subprocess.Popen(('/bin/sh','-c','curl 10.0.0.3:9918 -o /dev/null'),  stdout=sys.stdout, stderr=subprocess.STDOUT)

while :
    end=time.time()
    #print end-start
    if end-start>:
        p.terminate()
        break
    time.sleep()

sys.stdout=old
f.close()

以上是freebsd运行环境

下面是win7运行环境

import os,sys
import subprocess
import time
import random

def test(t):
    sys.path.append(r'd:\curl')
    start = time.time()
    timestr = time.strftime("%Y%m%d",time.gmtime(start))
    ran=random.uniform(, )
    filename="d:\\curl\data\\"+"log_"+str(timestr)+"_"+str(ran)+".txt"
    filepath = os.path.dirname(filename)
    if not os.path.exists(filepath):
        os.mkdir(filepath)
    f=open(filename,'w')
    old=sys.stdout
    sys.stdout=f
    #print time.strftime("\n%Y-%m-%d %H:%M:%S\n",time.gmtime(start))

    #cmdstr="d:\\curl\curl  10.0.0.1//data/myfun/source/resource/movies/3B0C5ACD8414D7B2918EBD75AE9843B6.mp4 -o null"
    cmdstr="d:\\curl\curl --limit-rate 100B  10.0.0.1//data/myfun/source/resource/movies/583B26DE308A12046251B3F2CA7C0755.mp4 -o null"
    p = subprocess.Popen(cmdstr,stdout = sys.stdout, stderr = subprocess.STDOUT,  shell = False)

    while :
        if (p.poll()==):
            p.terminate()
            time.sleep()
            break

    f.close()
    sys.stdout=old
    print "end>>>>>>>>>>>>>>>>>>>>"

test()
     

范例3：

import os,sys
import subprocess
import time
import random

def test():
    sys.path.append(r'd:\curl')
    start = time.time()
    timestr = time.strftime("%Y%m%d%H%M%S",time.gmtime(start))
    ran=random.uniform(, )
    filename="d:\\curl\data\\"+"log_"+str(timestr)+"_"+str(ran)+".txt"
    #filename="d:\\curl\data\\"+"log_"+str(timestr)+".txt"
    filepath = os.path.dirname(filename)
    if not os.path.exists(filepath):
        os.mkdir(filepath)
    f=open(filename,'w')

    sys.stdout=f
    cmdstr="d:\\curl\curl -x 10.0.0.54:3128  http://192.168.6.199/source/BT.mp4 -o null "

    print cmdstr
    p = subprocess.Popen(cmdstr,stdout = f, stderr = f,  shell = False)

    while :
        if (p.poll()==):
            p.terminate()
            time.sleep()
            break

    print "end>>>>>>>>>>>>>>>>>>>>"
    f.close() 

test()

            total_time=end-start
            #print "total time: ",total_time
            break

    #print "end>>>>>>>>>>>>>>>>>>>>"
    with open(filename,'r') as reader:
        data=reader.read()

    print data
    f_data=string.atof(data)
