Question

我制作了一个简单的网站，用户上传图片，然后在页面上显示。在get_root中：

@app.route('/', methods=['POST', 'GET'])
def get_root():
    if request.method == 'POST':
        return render_template("webpage2.html", image = upload_file())
    return render_template("webpage2.html")

在upload_file中：

@app.route('/upload/', methods = ['POST', 'GET'])
def upload_file():
    if request.method == 'POST':
        if 'fileToUpload' not in request.files:
            flash('No file part')
            return redirect(request.url)
        file = request.files['fileToUpload']
        if file.filename == '':
            flash('No selected file')
            return redirect(request.url)
        if file and allowed_file(file.filename):
            filename = secure_filename(file.filename)
            file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            return redirect(url_for('uploaded_file', filename=filename))

在uploaded_file（）中：

@app.route('/image/', methods = ['POST', 'GET'])
def uploaded_file(filename):
    return send_from_directory(app.config['UPLOAD_FOLDER'], filename)

当我测试它时，页面加载，但没有图像，我在控制台上收到以下错误：

TypeError: uploaded_file() takes exactly 1 argument (0 given)

我尝试过多种变体，但这似乎是我的主要问题：将正确的参数传递给uploaded_file。

将参数传递给flask.url_for（）
