Question

我正在创建一个文件。我发送base64字符串作为参数。这是我的代码：

def save_file(request_data):
    """
    """
    data = base64.b64decode(request_data.get('file'))
    file_type = imghdr.what('', h=data)
    if file_type not in ['pdf', 'txt', 'xls', 'xlsx', 'html']:
        return ({"msg": "Upload a valid file. The file you uploaded is not acceptable"}, 400)
    file = tempfile.TemporaryFile()
    file.write(data)
    file_size = os.fstat(file.fileno()).st_size
    name = str(file.name)+"."+str(file_type)
    content_type = magic.from_file(name, mime=True)
    uploaded_file = InMemoryUploadedFile(file=file, field_name='path', name=name,
                                        content_type=content_type, size=file_size, charset='utf-8')
    UploadedFile.objects.create(path=uploaded_file,
                         name=request_data.get('name'),
                         meta_info=request_data.get('meta_info', '{}'),
                         status=request_data.get('status', 'I'))
    file.close()
    return ({"msg": "File created successfully"}, 200)

我收到此错误：

文件不存在：32.jpeg

在这一行：

content_type = magic.from_file（name，mime = True）

有谁知道如何从base64字符串中获取内容类型？
