Question

我使用Django框架构建了一个网站，其中之一是处理用户上传的图像并将其保存在文件夹中以供下载，但是遇到错误（[Errno 13]权限被拒绝：After .png'）。我使用（python3 manage。py runserver），它可以工作，但是在与Apache 2一起部署时不起作用。

我知道这是Ubuntu权限的问题，但修改文件的权限后无法解决。我希望有人能给我一些建议。确实非常感谢您。

我的代码：

    exit('No direct script access allowed');

好吧，我解决了这个问题，我更改了图像的根部并且可以正常工作！

之前：

        Image.fromarray(im).save('After.png')

        file=open('After.png','rb')

之后：

        Image.fromarray(im).save('/home/Lenote/After.png')

        file=open('/home/Lenote/After.png','rb')

因为当我使用python3 manage.py runserver save('After.png')时将创建图像为/home/Lenote/After.png.，但是当我使用apache2时，可能会在未经许可的情况下在/etc/apache2/....中创建图像。

谢谢大家。特别要感谢Micheal J Roberts：）。
