wifi模块，传输图片。希望大佬回复

想实现的功能:先拍一张照片，保存到sd卡里面，然后手机链接wifi模块的热点之后，输入ip地址，可以一直看到那一张照片。希望有技术人员能提供代码参考。

参考传mjpeg视频流的例程

去掉while循环，就是仅传一次图片

去掉while，改if吗？

节后上班我回去试一下，header应该也需要改⁄(⁄ ⁄ ⁄ω⁄ ⁄ ⁄)⁄

请问一下，节后是什么时候？我有点赶时间，现在能不能指点一下？

@yuan 大佬，我把while改了if，但是连接wifi并不能看到哪一张照片，直接被刷过去了。给你看这个图!![0_1523006546556_F1C58~C~F310RA}WTN9(3N.png

加入了传输图片的程序

http://book.openmv.cc/shield/wifi.html

import sensor, image, time, network, usocket, sys

SSID ='OPENMV_AP'    # Network SSID
KEY  ='1234567890'    # Network key (must be 10 chars)
HOST = ''           # Use first available interface
PORT = 8080         # Arbitrary non-privileged port

# Reset sensor
sensor.reset()
# Set sensor settings
sensor.set_contrast(1)
sensor.set_brightness(1)
sensor.set_saturation(1)
sensor.set_gainceiling(16)
sensor.set_framesize(sensor.QQVGA)
sensor.set_pixformat(sensor.GRAYSCALE)

# Init wlan module in AP mode.
wlan = network.WINC(mode=network.WINC.MODE_AP)
wlan.start_ap(SSID, key=KEY, security=wlan.WEP, channel=2)

# You can block waiting for client to connect
#print(wlan.wait_for_sta(10000))

def response(s):
    print ('Waiting for connections..')
    client, addr = s.accept()
    # set client socket timeout to 2s
    client.settimeout(2.0)
    print ('Connected to ' + addr[0] + ':' + str(addr[1]))

    # Read request from client
    data = client.recv(1024)
    # Should parse client request here

    # Send multipart header
    client.send("HTTP/1.1 200 OK\r\n" \
                "Server: OpenMV\r\n" \
                "Content-Type: image/jpeg\r\n\r\n")

    # FPS clock
    clock = time.clock()

    # Start streaming images
    # NOTE: Disable IDE preview to increase streaming FPS.


    frame = sensor.snapshot()
    cframe = frame.compressed(quality=35)
    client.send(cframe)
    client.close()

while (True):
    # Create server socket
    s = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)
    try:
        # Bind and listen
        s.bind([HOST, PORT])
        s.listen(5)

        # Set server socket timeout
        # NOTE: Due to a WINC FW bug, the server socket must be closed and reopened if
        # the client disconnects. Use a timeout here to close and re-create the socket.
        s.settimeout(3)
        response(s)
    except OSError as e:
        s.close()
        print("socket error: ", e)
        #sys.print_exception(e)

谢谢大佬，但是刚刚我用其它方法已经搞定了。
