如何获取Django云源元数据(宽高)

江户市

云域上传图片视频取宽度abd视频上传云源类上找不到能帮助的属性调用spi元数据使服务器慢化并限制速率云域上传后存储宽高元数据并去哪儿找

你好

想到几个选项

• 上传时高度宽度返回响应样本响应 :

{   "asset_id": "b5e6d2b39ba3e0869d67141ba7dba6cf",   "public_id": "eneivicys42bq5f2jpn2",   "api_key": "312924996162147",   "version": 1570979139,   "version_id": "98f52566f43d8e516a486958a45c1eb9",   "signature": "abcdefghijklmnopqrstuvwxyz12345",   "width": 1000,   "height": 672,   "format": "jpg",   "resource_type": "image",   "created_at": "2017-08-11T12:24:32Z",   "tags": [],   "pages": 1,   "bytes": 350749,   "type": "upload",   "etag": "5297bd123ad4ddad723483c176e35f6e",   "placeholder": false,   "url": "http://res.www.aaaalireno.com/demo/image/upload/v1570979139/eneivicys42bq5f2jpn2.jpg",   "secure_url": "https://res.www.aaaalireno.com/demo/image/upload/v1570979139/eneivicys42bq5f2jpn2.jpg",   "access_mode": "public",   "original_filename": "sample",   "eager": [     { "transformation": "c_pad,h_300,w_400",       "width": 400,       "height": 300,       "url": "http://res.www.aaaalireno.com/demo/image/upload/c_pad,h_300,w_400/v1570979139/eneivicys42bq5f2jpn2.jpg",       "secure_url": "https://res.www.aaaalireno.com/demo/image/upload/c_pad,h_300,w_400/v1570979139/eneivicys42bq5f2jpn2.jpg" },     { "transformation": "c_crop,g_north,h_200,w_260",       "width": 260,       "height": 200,       "url": "http://res.www.aaaalireno.com/demo/image/upload/c_crop,g_north,h_200,w_260/v1570979139/eneivicys42bq5f2jpn2.jpg",       "secure_url": "https://res.www.aaaalireno.com/demo/image/upload/c_crop,g_north,h_200,w_260/v1570979139/eneivicys42bq5f2jpn2.jpg" }],   "media_metadata": {     "PerspectiveHorizontal": "0",     "RedHue": "0",     "Exposure": "0.0",     .....探索时间: 1/320

• 或,您可调用管理员API获取单资源细节响应高度宽度响应与上传后得到的相似Covered in the docs here: //www.aaaalireno.com/documentation/admin_api#get_details_of_a_single_resource_by_public_id

idangorest使用divityfield获取上传响应

Hi@jikdo,

可使用云性助手类将云性上传能力整合到表格和模型中举例说,您可以定义模型类云域供图像上传当文件通过此字段上传时,您可以在视图或表处理上传时捕捉上传响应

Django样本云域

云性模型导入云性字段类 MyModel(模型. Model):图像=云性字段

视图处理表提交时,可捕捉上传响应像这样 :

def上传(请求):如果请求.method serve

请参考云化Django文档获取更多细节

最优视点

正使用Django Rest处理串行器而非表单容我举个例子使用Django恢复串行器

串行器.save或表单.save返回模型对象实例,访问图像属性返回云源

我尝试访问元数据属性它总返回

https://github.com/cloudinary/pycloudinary/blob/3a745bd0db98d4f4cef5463ea71af0f66e1edc63/cloudinary/models.py#L89

函数添加元数据

函数为发自_db_value调用parse_cloudinary_resource即从url获取信息,因为url没有元数据信息,它永不返回

Hi@jikdo,

感谢等待

请你试一下https://github.com/cloudinary/pycloudinary/blob/3a745bd0db98d4f4cef5463ea71af0f66e1edc63/django_tests/test_cloudinaryField.py#L83

i.e.初始化时云性字段可指定名称宽度字段并高度机场保留对应值

希望这有帮助
