Flask Web开发基于Python的Web应用问题
我想用循环显示图片,但只能显示

我想增加第4个图片,请问该怎么解决?

程序代码：
from camera import Camera
from flask import Flask, render_template, Response

app = Flask(name)

@app.route(’/’)

def index():
return render_template(‘index.html’)

def gen(camera):
while True:
frame = camera.get_frame()
yield (b’–frame\r\n’
b’Content-Type: image/jpeg\r\n\r\n’ + frame + b’\r\n’)

@app.route(’/video_feed’)
def video_feed():
return Response(gen(Camera()),
mimetype=‘multipart/x-mixed-replace; boundary=frame’)

if name == ‘main’:
app.run(host=‘0.0.0.0’, threaded=True)

程序代码：
import time import time

class Camera(object):
def__int__(self):
self.frames = [open(f + ‘.jpg’, 'rb).read() for f in [‘1’, ‘2’, ‘3’]]

def get_frame(self):
   return self.frames[int(time()) % 3]
