為python設(shè)置socket代理首先,你得下載SocksiPy這個(gè).解壓出來之后里面會(huì)有一個(gè)socks.py文件.然后你可以把這個(gè)文件復(fù)制到python安裝目錄里面的Lib\site-packages中.或者把這個(gè)文件復(fù)制到程序所在的目錄中.

然后就可以再程序中使用socket代理來編寫程序了.

下面是示例代碼

import socks

import socket

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5,"127.0.0.1",8088)

socket.socket =socks.socksocket

import urllib2

urllib2.urlopen('http://www.baidu.com').read()

通過socket通信實(shí)現(xiàn)遠(yuǎn)程攝像頭監(jiān)控通過python來實(shí)現(xiàn)攝像頭監(jiān)控,然后通過socket通信來將數(shù)據(jù)發(fā)送到遠(yuǎn)程服務(wù)器,這樣就可以實(shí)現(xiàn)遠(yuǎn)程監(jiān)控了.大概找了下資料,果然可以,下面貼出實(shí)現(xiàn)過程.

這個(gè)程序包括一個(gè)服務(wù)器和一個(gè)客戶端。需要的庫(kù)有 VideoCapture 和 pygame，一個(gè)用來得到攝像頭的視頻，一個(gè)用來顯示.

服務(wù)器端,主要實(shí)現(xiàn)監(jiān)聽客戶端所發(fā)送到指令,如果指令是startCam,則打開攝像頭,并向客戶端發(fā)送數(shù)據(jù).

from VideoCapture import Device

import ImageDraw, sys, pygame, time

from pygame.locals import *

import socket

import time

from PIL import ImageEnhance

from threading import Thread

import traceback

import threading

# 全局變量

is_sending = False

cli_address = ('', 0)

# 主機(jī)地址和端口

host = 'localhost'

port = 10218

# 初始化UDP socket

ser_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

ser_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

ser_socket.bind((host, port))

# 接收線程類，用于接收客戶端發(fā)送的消息

class UdpReceiver(threading.Thread):

def __init__(self):

threading.Thread.__init__(self)

self.thread_stop = False

def run(self):

while not self.thread_stop:

# 聲明全局變量，接收消息后更改

global cli_address

global is_sending

try:

message, address = ser_socket.recvfrom(2048)

except:

traceback.print_exc()

continue

print message,cli_address

cli_address = address

if message == 'startCam':

print 'start camera',

is_sending = True

ser_socket.sendto('startRcv', cli_address)

if message == 'quitCam':

is_sending = False

def stop(self):

self.thread_stop = True

if __name__=='__main__':

res = (640,480)

cam = Device()

cam.setResolution(res[0],res[1])

brightness = 1.0

contrast = 1.0

shots = 0

receiveThread = UdpReceiver()

receiveThread.setDaemon(True) # 該選項(xiàng)設(shè)置后使得主線程退出后子線程同時(shí)退出

receiveThread.start()

while 1:

if is_sending:

camshot = ImageEnhance.Brightness(cam.getImage()).enhance(brightness)

camshot = ImageEnhance.Contrast(camshot).enhance(contrast)

clock = pygame.time.Clock()

img = cam.getImage().resize((160,120))

data = img.tostring()

ser_socket.sendto(data, cli_address)

time.sleep(0.05)

else:

time.sleep(1)

receiveThread.stop()

ser_socket.close()

客戶端:

主要功能是像服務(wù)器端發(fā)送指令,然后接受服務(wù)器所發(fā)送過來的數(shù)據(jù)并通過pygame模塊來顯示出來.

# -*- coding: UTF-8 -*-

import socket, time

import pygame

from pygame.locals import *

from sys import exit

# 服務(wù)器地址，初始化socket

ser_address = ('localhost', 10218)

cli_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 設(shè)置超時(shí)

cli_socket.settimeout(5)

# 向服務(wù)器發(fā)送消息，并判斷接收時(shí)是否超時(shí)，若超時(shí)則重發(fā)

while 1:

cli_socket.sendto('startCam', ser_address)

try:

message, address = cli_socket.recvfrom(2048)

if message == 'startRcv':

print message

break

except socket.timeout:

continue

cli_socket.recvfrom(65536)

# 初始化視頻窗口

pygame.init()

screen = pygame.display.set_mode((640,480))

pygame.display.set_caption('Web Camera')

pygame.display.flip()

# 設(shè)置時(shí)間，可以用來控制幀率

clock = pygame.time.Clock()

# 主循環(huán)，顯示視頻信息

while 1:

try:

data, address = cli_socket.recvfrom(65536)

except socket.timeout:

continue

camshot = pygame.image.frombuffer(data, (160,120), 'RGB')

camshot = pygame.transform.scale(camshot, (640, 480))

for event in pygame.event.get():

if event.type == pygame.QUIT:

cli_socket.sendto('quitCam', ser_address)

cli_socket.close()

pygame.quit()

exit()

screen.blit(camshot, (0,0))

pygame.display.update()

clock.tick(20)

客戶端就是簡(jiǎn)單地向服務(wù)器發(fā)送啟動(dòng)消息，接收到回復(fù)后開始進(jìn)入主循環(huán)開始接收視頻數(shù)據(jù)并顯示。

由于UDP協(xié)議不保證信息是否成功到達(dá)，因此前面設(shè)置了個(gè)重發(fā)機(jī)制，只有當(dāng)客戶端收到服務(wù)器的回復(fù)后，才停止發(fā)送開啟消息并進(jìn)入主循環(huán).具體見注釋.

使用時(shí)將localhost改成服務(wù)器IP即可.
