import timephoto = Blueprint('photo', __name__)@photo.route('/stream')
def stream():def generate():for i in range(10):yield f"data: {i}\n\n"time.sleep(1) # 模拟延迟1秒headers = {'Content-Type': 'text/event-stream','Cache-Control': 'no-cache','X-Accel-Buffering': 'no',"Access-Control-Allow-Origin": "*","Access-Control-Allow-Methods": "GET,POST","Access-Control-Allow-Headers": "x-requested-with,content-type"}return Response(stream_with_context(generate()),headers=headers)html
