处理图片：

def pic_class(request):    upload_file = request.FILES.get("myfile", None)  # 获取上传的文件，如果没有文件，则默认为None    file_obj = request.FILES.get('file')    if file_obj:   # 处理附件上传到方法        request_set = {}        print('file--obj', file_obj)        # user_home_dir = "upload/%s" % (request.user.userprofile.id)        # accessory_dir = settings.accessory_dir        # if not os.path.isdir(accessory_dir):        #     os.mkdir(accessory_dir)        scr = Image.open(file_obj)        img= np.asarray(scr)

with open(upload_file, 'wb') as new_file:    for chunk in file_obj.chunks():        new_file.write(chunk)

### get the inmemory file

data = request.FILES.get('btn_file') # get the file from the curl

### write the data to a temp file

tup = tempfile.mkstemp() # make a tmp file

f = os.fdopen(tup[0], 'w') # open the tmp file for writing

f.write(data.read()) # write the tmp file

f.close()

### return the path of the file

filepath = tup[1] # get the filepath

return filepath
