Vue3 切片上传组件是一个基于 Vue3 开发的组件,用于实现大文件的切片上传,可提高上传速度和稳定性。
该组件主要包含以下功能:
1. 支持文件切片上传;
2. 支持上传进度显示;
3. 支持上传暂停和继续;
4. 支持上传失败重试;
5. 支持上传完成后的回调函数。
使用该组件可以方便地实现大文件的上传,提高用户体验和操作效率。
以下是该组件的部分代码示例:
```vue
<template>
<div>
<div class="file-input">
<input type="file" @change="handleFileChange">
</div>
<div class="file-info">
<p>文件名:{{ file.name }}</p>
<p>文件大小:{{ formatFileSize(file.size) }}</p>
</div>
<div class="file-progress">
<p>上传进度:{{ Math.floor(progress * 100) }}%</p>
<div class="progress-bar" :style="{ width: (progress * 100) + '%' }"></div>
</div>
<div class="file-actions">
<button v-if="!isUploading" @click="startUpload">开始上传</button>
<button v-if="isUploading" @click="pauseUpload">暂停上传</button>
<button v-if="!isUploading && progress > 0" @click="resumeUpload">继续上传</button>
<button v-if="isPaused || progress === 0" @click="retryUpload">重新上传</button>
</div>
</div>
</template>
<script>
import { defineComponent, ref } from 'vue';
import SliceUploader from 'slice-uploader';
export default defineComponent({
name: 'SliceUploaderDemo',
components: { SliceUploader },
setup() {
const file = ref(null);
const progress = ref(0);
const isUploading = ref(false);
const uploader = new SliceUploader({
url: 'http://localhost:3000/upload',
headers: {
Authorization: 'Bearer xxxxxxxxxxxxxxx',
},
onProgress: (p) => {
progress.value = p;
},
onSuccess: (res) => {
console.log(res);
},
onError: (err) => {
console.error(err);
},
});
const handleFileChange = (event) => {
file.value = event.target.files[0];
};
const startUpload = () => {
if (!file.value) {
alert('请选择要上传的文件');
return;
}
uploader.upload(file.value);
isUploading.value = true;
};
const pauseUpload = () => {
uploader.pause();
isUploading.value = false;
};
const resumeUpload = () => {
uploader.resume();
isUploading.value = true;
};
const retryUpload = () => {
uploader.retry();
isUploading.value = true;
};
const formatFileSize = (size) => {
const units = ['B', 'KB', 'MB', 'GB', 'TB'];
let i = 0;
while (size >= 1024 && i < units.length - 1) {
size /= 1024;
i++;
}
return `${size.toFixed(2)} ${units[i]}`;
};
return {
file,
progress,
isUploading,
handleFileChange,
startUpload,
pauseUpload,
resumeUpload,
retryUpload,
formatFileSize,
};
},
});
</script>
```
以上是一个简单的切片上传组件示例,其中包含了文件选择、上传进度显示、上传暂停和继续、上传失败重试等功能。开发者可以根据自己的需求进行定制和扩展。
