Folder and files upload with Flask
提问by SamuraiT
I can upload a File with flask by following Uploading Files:
- A
<form>tag is marked withenctype=multipart/form-dataand an<input type=file>is placed in that form. - The application accesses the file from the files dictionary on the request object.
- Use the
save()method of the file to save the file permanently somewhere on the filesystem.
- 甲
<form>标签标有enctype=multipart/form-data和一个<input type=file>被放置在该形式。 - 应用程序从请求对象的文件字典中访问文件。
- 使用
save()文件的方法将文件永久保存在文件系统的某处。
But I don't know how to upload folder or some files. I searched, and I found Uploading multiple files with Flask.
但我不知道如何上传文件夹或一些文件。我搜索了一下，发现使用 Flask 上传多个文件。
However, still I don't know how to upload a folder and files that belong to the folder.
但是，我仍然不知道如何上传属于该文件夹的文件夹和文件。
Could you please tell how?
你能告诉我怎么做吗？

@app.route('/upload/',methods = ['GET','POST'])
def upload_file():
if request.method =='POST':
file = request.files['file']
if file:
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'],filename))
return hello()

<input type='submit' value='upload'>

the issue here is that flask's app.configisn't relative to itself, it's absolute. so when you put:
这里的问题是烧瓶app.config与自身无关，它是绝对的。所以当你把：
UPLOAD_FOLDER = './uploads'
flask doesn't find this directory and returns a 500error.
if you changed it to:
flask 找不到此目录并返回500错误。如果您将其更改为：
UPLOAD_FOLDER = '/tmp'
and then uploaded your file and navigated to the /tmp/ directory you would see it.
然后上传您的文件并导航到您会看到的 /tmp/ 目录。
you will need to edit your path to the proper directory for the file to be uploaded properly.
您需要编辑正确目录的路径才能正确上传文件。

file = request.files['file']
change it to
将其更改为
file = request.files['file[]']
