python中使用socket服务发送接收图像的代码，可在服务器端中插入模型推理代码进行推理返回结果。
服务器端
python
# -*-coding:utf-8-*-
import os.path
import socket
import struct
def deal_image(sock, addr):
print('connection', addr)
while True:
# 计算文件信息大小
fileinfo_size = struct.calcsize('128sq')
# 接收文件信息buf
buf = sock.recv(fileinfo_size)
if buf:
# 解包
filename, filesize = struct.unpack('128sq', buf)
fn = filename.decode().strip('\x00')
new_filename = os.path.join('./', 'new_' + fn)
recvd_size = 0
# 保存图像
fp = open(new_filename, 'wb')
# 没看董
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
# 写数据
fp.write(data)
# 关闭文件
fp.close()
# 关闭服务
sock.close()

# 建立连接
s = socket.socket()

s.bind((host, port))
s.listen(5)

c, addr = s.accept()
str = 'hello,world,' + str(addr)
# 发送连接消息，以信息流的方式发送
c.send(str.encode(encoding='utf-8'))
print(addr)
# 处理接收的图像数据
deal_image(c, addr)
c.close()客户端
