HMedia实现对本地化图片的丝滑般生成缩略图

我经常使用阿里云的oss服务，我最喜欢oss的功能就是通过简单的参数，就能实现图片的缩略图与格式转换。

但是，如果图片使用本地存储时候，就没办法使用oss的生成缩略图和格式转换功能了。

所以，借着一个项目必须本地化部署的背景，我写了一个模块，让前端方便进行对应渲染。

快速开始

安装

pip install hmedia

在url.py中增加以下代码

from django.urls import re_path
from hmedia.views import hmedia

urlpatterns = [
    re_path(r'^media/(?P<path>.*)$', hmedia),
]

注意，示例中urlpatterns的内容，是增加在您原有内容里，不是覆盖。

另外，media目录是在settings里配置的静态文件目录。如果你不一样，请修改，我的settings内容如下：

MEDIA_URL = 'media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')

所以是media。

使用方式

前端调用时候，参考阿里云的oss语法规范，目前仅支持图片缩放、格式转换功能。

传送门：阿里云oss图片处理 (https://help.aliyun.com/zh/oss/user-guide/resize-images-4?spm=a2c4g.11186623.0.i1)

也可以在oss管理中的数据处理里，配置图片处理规则，参考其设定的前端调用代码。

HMedia realizes smooth thumbnail generation for localized images
I often use Alibaba Cloud’s OSS service. My favorite feature of OSS is that it can realize thumbnail and format conversion of images through simple parameters.

However, if the image is stored locally, there is no way to use OSS’s thumbnail generation and format conversion functions.

Therefore, taking advantage of the background that a project must be deployed locally, I wrote a module to facilitate the corresponding rendering of the front end.

Quick Start
Installation
pip install hmedia
Add the following code in url.py

from django.urls import re_path
from hmedia.views import hmedia

urlpatterns = [
re_path(r’^media/(?P.*)$', hmedia),
]
Note that the content of urlpatterns in the example is added to your original content, not overwritten.

In addition, the media directory is the static file directory configured in settings. If your settings are different, please modify them. My settings are as follows:

MEDIA_URL = ‘media/’
MEDIA_ROOT = os.path.join(BASE_DIR, ‘media/’)
So it is media.

Usage
When calling the front end, refer to Alibaba Cloud’s OSS syntax specifications. Currently, only image scaling and format conversion functions are supported.

Portal: Alibaba Cloud OSS Image Processing (https://help.aliyun.com/zh/oss/user-guide/resize-images-4?spm=a2c4g.11186623.0.i1)

You can also configure image processing rules in the data processing in OSS management, and refer to the front-end call code set by it.
