Django的ImageField内置了这个功能。您只需添加两个新的列，用于宽度和高度：
class article(models.model):
image1 = models.ImageField(width_field='image1_width', height_field='image1_height', upload_to='images', blank=True)
image1_width = models.IntegerField(blank=True, null=True)
image1_height = models.IntegerField(blank=True, null=True)
然后您可以简单地进行如下操作：
<meta property="og:image" content="{{ article.image1 }}" />
<meta property="og:image:secure_url" content="{{ article.image1 }}" />
<meta property="og:image:width" content="{{ article.image1_width }}" />
<meta property="og:image:height" content="{{ article.image1_height }}" />

Django ImageField has a built-in feature for this. You just need to add two new columns for width and height:
class article(models.model):
image1 = models.ImageField(width_field='image1_width', height_field='image1_height', upload_to='images', blank=True)
image1_width = models.IntegerField(blank=True, null=True)
image1_height = models.IntegerField(blank=True, null=True)
Then you can simply do:
<meta property="og:image" content="{{ article.image1 }}" />
<meta property="og:image:secure_url" content="{{ article.image1 }}" />
<meta property="og:image:width" content="{{ article.image1_width }}" />
<meta property="og:image:height" content="{{ article.image1_height }}" />```

我的 models.py：
class article(models.model):
image1 = models.ImageField(upload_to='images', width_field='image1_width', height_field='image1_height')
image1_width = models.IntegerField(editable=False, null=True)
image1_height = models.IntegerField(editable=False, null=True)
我的代码中的 head.html：
<meta property="og:image" content="{{ article.image1 }}" />
<meta property="og:image:secure_url" content="{{ article.image1 }}" />
<meta property="og:image:width" content="{{ article.image1_width }}" />
<meta property="og:image:height" content="{{ article.image1_height }}" />

image1_width = models.IntegerField(editable=False, null=True)
image1_height = models.IntegerField(editable=False, null=True)
my code head.html
<meta property="og:image" content="{{ article.image1 }}" />
<meta property="og:image:secure_url" content="{{ article.image1 }}" />
<meta property="og:image:width" content="{{ article.image1_width }}" />
