如何使用 Sanic 服务上传的图片?

How to serve uploaded image using Sanic?

我已经使用Sanic成功上传了我项目中某个目录中的图像。我用来上传图片的代码如下:

class ImageUploadAPI(HTTPMethodView):
    async def post(self, request):
        access_token = get_token_from_header(request.headers)
        token = decode_token(access_token)
        user_id = token.get('sub')
        upload_file = request.files.get('image')
        log_path = os.path.join(os.getcwd(), 'pictures')
        if not os.path.exists(log_path):
            os.makedirs(log_path)

        if not upload_file:
            res = {'status': 'no file uploaded'}
            return json(res, status=404)

    # if not valid_file_type(upload_file.name, upload_file.type):
    #     res = {'status': 'invalid file type'}
    #     return json(res, status=400)
        elif not valid_file_size(upload_file.body):
            res = {'status': 'invalid file size'}
            return json(res, status=400)
        else:
            file_path = f"{log_path}/{str(datetime.now())}.{upload_file.name.split('.')[1]}"
            await write_file(file_path, upload_file.body)
            await apps.db.users.update_one({'_id': ObjectId(user_id)}, {"$set": {
            "nid_front": upload_file.name
            }})
            return json({'status': 'image uploaded successfully'})

在此过程中,我将 upload_file.name 保存在 user 字段中。 现在为上传的图片提供服务,我访问了以下 url(因为我在本地服务器http://localhost:8000/10414532_479247615552487_2110029531698825823_n.jpg 但它不显示图像而是显示,

Error: Requested URL /10414532_479247615552487_2110029531698825823_n.jpg not found

如何提供上传的图片?

我找到了阅读 Sanic static files 的解决方案。 我使用 blueprint 选项将我上传的图片作为:

static_file_bp = Blueprint('static', url_prefix='/files')
static_file_bp.static('/static', './uploads')
