Steps to reproduce

在给Upload组件传值defaultFileList对象中设置url为.do类型的后缀名（非常规的jpg, jpeg, gif等等后缀名）时,代码如下
<a-upload
.....
:defaultFileList="fileList"

export default {
data() {
return {
fileList: [
{
uid: '-1',
name: 'xxx.png',
status: 'done',
url: 'xxx.do',
}
],
};
},
};

What is expected?

期望能正常显示图片

What is actually happening?

图片显示为一个file icon。而不是图片。

查找到是在这个文件中/ant-design-vue/es/upload/UploadList.js中isImageUrl方法中会检测图片url的后缀名，如果不是常规图片后缀名，return false, 但是图片中也有一种形式，通过后端.do接口返回数据流。而数据流是图片。这里可以改造或者可配置？

传递file的type为image即可解决
