Flask学习笔记(四):基于Flask网页显示图片

原图如下

代码如下

from flask import Flask, request, make_response
from datetime import datetime
import os

app = Flask(__name__)
IMG_PATH = "F:\pycharm/feature_match/4.jpg"

@app.route('/display/img/<string:filename>', methods=['GET'])
def display_img(filename):
    request_begin_time = datetime.today()
    print("request_begin_time", request_begin_time)
    if request.method == 'GET':
        image_data = open(IMG_PATH, "rb").read()
        response = make_response(image_data)
        response.headers['Content-Type'] = 'image/jpg'
        return response
    else:
        pass

if __name__ == '__main__':
    app.run(host='10.16.55.26', port=5001)

然后通过网页打开http://10.16.55.26:5001/display/img/4.jpg（10.16.55.26为自己的IP地址）
效果如下
