树莓派利用socket传图到pc端（Python）

1.PC作为socket的服务器端：

import socket
import os
import sys
import struct


def socket_service():
    try:
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        #IP地址留空默认是本机IP地址
        s.bind(('', 8088))
        s.listen(7)
    except socket.error as msg:
        print(msg)
        sys.exit(1)

    print("连接开启，等待传图...")
	
    while True:
        sock, addr = s.accept()
        deal_data(sock, addr)

    s.close()


def deal_data(sock, addr):
    print("成功连接上 {0}".format(addr))

    while True:
        fileinfo_size = struct.calcsize('128sl')
        buf = sock.recv(fileinfo_size)
        if buf:
            filename, filesize = struct.unpack('128sl', buf)
            fn = filename.decode().strip('\x00')
            #PC端图片保存路径
            new_filename = os.path.join('C:/Users/user/Desktop', fn)

            recvd_size = 0
            fp = open(new_filename, 'wb')

            while not recvd_size == filesize:
                if filesize - recvd_size > 1024:
                    data = sock.recv(1024)
                    recvd_size += len(data)
                else:
                    data = sock.recv(1024)
                    recvd_size = filesize
                fp.write(data)
            fp.close()
        sock.close()
        break


if __name__ == '__main__':
    socket_service()

2.树莓派作为socket的客户端：

import socket
import os
import sys
import struct


def sock_client():
    try:
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        #192.168.199.1和8088分别为服务端（pc）的IP地址和网络端口
        s.connect(('192.168.199.1', 8088))
    except socket.error as msg:
        print(msg)
        print(sys.exit(1))

    while True:
        #filepath是要被发送图片的路径
        filepath = '/home/pi/ceshi/image.jpg'
        fhead = struct.pack(b'128sl', bytes(os.path.basename(filepath), encoding='utf-8'), os.stat(filepath).st_size)
        s.send(fhead)
        print('client filepath: {0}'.format(filepath))

        fp = open(filepath, 'rb')
        while 1:
            data = fp.read(1024)
            if not data:
                print('{0} 发送成功...'.format(filepath))
                break
            s.send(data)
        s.close()
        break

if __name__ == '__main__':
    sock_client()

socket连接，如果连接不成功直接退出程序sys.exit(1)：

try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    #192.168.199.1和8088分别为服务端（pc）的IP地址和网络端口
    s.connect(('192.168.199.1', 8088))
except socket.error as msg:
    print(msg)
    print(sys.exit(1))
