Problems using v-bind in CSS

[cloudmoonocus]

I want to dynamically bind the background image, and this variable gets the image from the API, but there is a url() for setting the background image, I don't know how to write v-bind here. And, I do it via pseudo-elements and can't use style on HTML. So what should I do here?

我想动态绑定背景图片，并且这个变量从API获取的图片，但是设置背景图片有个url()，我不清楚这里怎么写v-bind。并且，我是通过伪元素实现的，无法在HTML上使用style。那么请问我这里应该如何做？
