Question

我正在设置一个flask应用程序，以通过用户界面运行机器学习模型。我在高级文本（Windows）上运行python3。我无法将文件保存到目录，除非抛出错误PermissionDenied Errno13

我的文件夹Web_Demo包含Flask中的静态文件，模板和main。

我尝试使用绝对路径名，但是仍然有相同的错误。

app.config["UPLOAD_FOLDER"]= 'D:/Web_Demo/static/'
@app.route('/analysis.html',methods=['GET', 'POST'])
def analysis():

    if request.method == "POST":
        if request.files:
            file=request.files["data"]
            filename=secure_filename(file.filename)
            file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))

            return redirect(request.url)


    return render_template('/analysis.html')

我按下上传按钮后立即收到此错误。这是我选择和上传文件本身的先决条件。 PermissionError: [Errno 13] Permission denied: 'D:/Web_Demo/static/'

我相信我没有写此文件夹的权限。如果是这样，我该如何完成？我已经阅读了有关sudo 775的解决方案，但无法实现或理解它。任何帮助将不胜感激。

整个回溯如下：

Answer 1

尝试使用app.config["UPLOAD_FOLDER"]= './static'，但不要在结尾加上/，通常这应该可行。

无法在Flask应用程序上保存和读取文件
