uniapp实现文件预览过程

H5实现预览

<template>
    <iframe :src="_url" style="width:100vw; height: 100vh;" frameborder="0"></iframe>
</template>
<script lang="ts">
export default {
    data() {
        return {
            _url: '',
        }
    },
    onLoad(options: {_url: string}) {
        // 第一：https://docs.google.com/viewer?url=
        // 第二：https://view.officeapps.live.com/op/view.aspx?src=
        this._url = `https://view.officeapps.live.com/op/view.aspx?src=${options._url}`
        console.log(this._url,'this._url')
    }
}
</script>

小程序和app预览

                uni.downloadFile({
					    url: url,
					    success: function (res) {
						var filePath = res.tempFilePath;
						uni.openDocument({
							filePath: filePath,
							showMenu: true,
							success: function (res) {
								console.log('打开文档成功');
							}
						});
					}
				});
