Python uploads zip attachments and performs decompression

1、 First, get the uploaded file from the front end

f = request.files['upload']

2、 Configuration save path

savepath = "/opt/upload/"
if not os.path.exists(savepath): # Determine whether the directory exists , If it doesn't exist, create a new one
os.makedirs(savepath)

3、 Save after configuring the path

upload_path = os.path.join(savepath, secure_filename(f.filename))
f.save(upload_path)

4、 Determine whether zip File and extract

if zipfile.is_zipfile(upload_path): # Determine whether zip file
zf = zipfile.ZipFile(upload_path, 'r') # Set the file to readable
stem, suffix = os.path.splitext(f.filename) # Extract file name
for file in zf.namelist(): # Traversal file
zf.extract(file, savepath + "/" + stem) # Extract to the specified directory
