這篇文章主要介紹了Python設置Socket代理及實現遠程攝像頭控制的例子,皆是對socket模塊的實際運用,需要的朋友可以參考下

為python設置socket代理

首先,你得下載SocksiPy這個.解壓出來之后里面會有一個socks.py文件.然后你可以把這個文件復制到python安裝目錄里面的Lib/site-packages中.或者把這個文件復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通信實現遠程攝像頭監控

通過python來實現攝像頭監控,然后通過socket通信來將數據發送到遠程服務器,這樣就可以實現遠程監控了.大概找了下資料,果然可以,下面貼出實現過程.

這個程序包括一個服務器和一個客戶端。需要的庫有 VideoCapture 和 pygame，一個用來得到攝像頭的視頻，一個用來顯示.

服務器端,主要實現監聽客戶端所發送到指令,如果指令是startCam,則打開攝像頭,并向客戶端發送數據.

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

print 'quit camera',

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) # 該選項設置后使得主線程退出后子線程同時退出

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:

主要功能是像服務器端發送指令,然后接受服務器所發送過來的數據并通過pygame模塊來顯示出來.

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

import socket, time

import pygame

from pygame.locals import *

from sys import exit

# 服務器地址，初始化socket

ser_address = ('localhost', 10218)

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

# 設置超時

cli_socket.settimeout(5)

# 向服務器發送消息，并判斷接收時是否超時，若超時則重發

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()

# 設置時間，可以用來控制幀率

clock = pygame.time.Clock()

# 主循環，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)
