您可以使用Antd的<a href="https://ant.design/components/upload-cn/#API" target="_blank">Upload组件</a>来上传文件,然后使用<a href="https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL" target="_blank">URL.createObjectURL()</a>方法将文件转换为URL,最后使用<a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement/download" target="_blank">download属性</a>将URL下载到本地。以下是示例代码:
```html
<template>
<a-upload
:before-upload="beforeUpload"
:on-success="onSuccess"
:on-error="onError"
>
<a-button>
<a-icon type="upload" /> 点击上传
</a-button>
</a-upload>
</template>
<script>
export default {
methods: {
beforeUpload(file) {
// 可以在这里对文件进行验证
return true;
},
onSuccess(response, file) {
const url = URL.createObjectURL(file);
const link = document.createElement('a');
link.href = url;
link.setAttribute('download', file.name);
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
URL.revokeObjectURL(url);
},
onError(error) {
console.error(error);
},
},
};
</script>
```
