Question

我将Flask用作移动应用程序的后端，其功能之一是上传和重命名个人资料图片的图像并发布媒体附件

最近，在开发服务器上使用它们时，上传的Web服务返回list_c = a.objects.filter(param1='a', param2='b').values_list('c', flat=True) list_d = a.objects.filter(param1='a', param2='b').values_list('d', flat=True) b.objects.filter(param3__in=list_c, param4__in=list_d).delete()和FileNotFoundError: [Errno 2] No such file or directory

我真的不认为这是一个代码问题，因为它在我的本地环境下可以正常工作，但是在那儿崩溃了。

这是来自开发服务器的回溯

500 Error

这是发布功能

我已经将上载目录更改为可由@jwt_required() def post(request): if 'file' not in request.files: return { 'success': False, 'message': 'No file part in the request', }, 200 file = request.files['file'] if file.filename == '': return { 'success': False, 'message': 'No file selected for uploading', }, 200 if file and allowed_file(file.mimetype): filepath = makepath(file.mimetype) file.save(filepath) post = post_repo.create( current_identity.id, request.form['matchId'], request.form['teamSelected'], request.form['content'], request.form['postType'], filepath, request.form['location'] ) if post: return { 'success': True, 'message': 'Post successfully created', 'post': post_repo.to_dto(post), }, 201 return { 'success': False, 'message': 'File extension not allowed', }, 200写入

dev环境使用apache 2.4和wsgi托管在docker环境中，以便为其提供服务

我应该问服务器管理员在那里签到什么？

编辑：我刚刚注意到，当我others目录时，没有组列。难道就是为什么上传不起作用？

ls -la

更新：如注释中所建议，我尝试使用保存功能时使用绝对路径，这导致stacktrace中出现奇怪的错误消息，它生成了其他内容，例如{{ 1}}，在文件夹名称前添加一个/，这很有意义，为什么在这里失败，因为该路径在服务器上不存在

使用Flask上传文件时出现FileNotFoundError
