Flask Web开发基于Python的Web应用问题
如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]
