在运行时更改上传路径 (UPLOAD_FOLDER)

Question

如何在运行时更改上传文件夹？我希望能够更改文件上传到的位置，但我不知道如何更改。

我试过这样的事情，但我得到KeyError：

@app.route('/upload', methods=['POST'])
def upload():
    file = request.files['file']
    path = 'uploads/text'
    if file and allowed_file(file.filename):
        filename = secure_filename(file.filename)
        UPLOAD_FOLDER = path
        file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
        return redirect(url_for('uploaded_file',
                                filename=filename))

Answer 1

你可以试试这个

file.save(os.path.join(/path/to/save/, filename))

在你的

UPLOAD_FOLDER = path
file.save(os.path.join(UPLOAD_FOLDER, filename))
