Question

我是Flask的新手，我尝试将图片上传到静态文件夹并使用cv2制作高斯图像

`@app.route('/upload', methods=['GET', 'POST'])
def upload():
    if request.method == 'POST' and 'photo' in request.files:
        filename = photos.save(request.files['photo'])
        return "Your image has been save" + myfunction(filename)
    return render_template('upload.html')
`

上传正在运行，但是当我尝试使用cv2使图像成为高斯模糊时发生错误

RuntimeError：无法访问请求外的配置

@app.route('/upload/filename')
def myfunction(filename):
    img = cv2.imread(filename)
    gblur = cv2.GaussianBlur(img, (5, 5), 0)
    return render_template('show.html', gblur=gblur)

show.html

<body>
    {% if gblur %}
      <h1>Image Gaussian Blur</h1><br>
      <img src="{{ url_for('static', gblur=gblur) }}">
      <br><button><a href="{{ url_for('upload') }}">Go back to Upload New Image</a></button>
    {% else %}
      <h1>no image for whatever reason</h1>
    {% endif %}
</body>

任何人都有任何想法？感谢。
