使用Python中的套接字編程接收圖像

Question

我正在嘗試接收python中的圖像以在程序中使用它。

這是服務器代碼：

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("127.0.0.1", 5005))
server_socket.listen(5)

data = ' ' 
client_socket, address = server_socket.accept()
print "Conencted to - ",address,"\n"
while (1):
    data = client_socket.recv(1024)
    print "The following data was received - ",data
    print "Opening file - ",data
    img = open(data,'r')
    while True:
      strng = img.readline(512)
      if not strng:
        break
      client_socket.send(strng)
      img.close()
      print "Data sent successfully"
      exit()
      #data = 'viewnior '+data
      #os.system(data)

這是客戶端代碼：

import socket,os
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(("127.0.0.1", 5005))
size = 1024

while(1):
    print "Enter file name of the image with extentsion (example: filename.jpg,filename.png or if a video file then filename.mpg etc) - "
    fname = raw_input()
    client_socket.send(fname)
    #fname = 'documents/'+fname
    fp = open(fname,'w')
    while True:
        strng = client_socket.recv(512)
        if not strng:
            break
        fp.write(strng)
    fp.close()
    print "Data Received successfully"
    exit()
    #data = 'viewnior '+fname
    #os.system(data)

現在應該閱讀收到的內容，以便能夠使用它。 我正在這樣打開它：

input_image = Image.open('data').convert('L').resize((100, 100))

但是當我在cmd中運行兩個代碼時，輸​​出為： The following data was received - + path Opening file - + path雖然應該使用圖像並顯示最終輸出，但是什么也沒有發生。

有人可以幫忙嗎？

我不知道這是否是您的（唯一的）問題，但是在處理二進制文件時，應將b標志傳遞給內置函數open ：

img = open(data, 'rb')
