<template>
<div>
请选择上传幻灯图片:
<input type="file" id="back" ref="backfile" multiple @change="handleFile" />
<div id="imglist" style="width:100%;">
<div v-for="(item,i) in selFiles" :key="i" style="float:left;margin-left: 20px;margin-top: 20px;height:150px;position:relative;">
<img :src="item.fileimg" style="height:150px;"/>
<div @click="delqueue(i)" style="position:absolute;width:30px;height:30px;line-height:30px;border-radius:15px;top:-15px;right:-15px;background:#ff0000;">x</div>
</div>
</div>
<input type="button" value="上传" @click="upload" />
</div>
</template>
<script>
import {ref} from "vue"
import axios from 'axios';
export default {
name: "MultiUploadImg",
setup() {
//选中的图片文件，保存在数组中
const selFiles = ref([]);
//选中图片后的处理
const handleFile = () => {
let filePaths = window.event.target.files;
//清空原有缩略图
if (filePaths.length === 0) {
//未选择，则返回
return
} else {
//清空数组中原有图片
selFiles.value.length = 0;
}
//把新选中的图片加入数组
for( var i=0;i<filePaths.length; i++ ){
let file = filePaths[i];
let one = {
fileimg:URL.createObjectURL(file), //预览用
file:file,
}
selFiles.value.push(one);
}
}
//从上传数组中删除
const delqueue = (index) => {
if (confirm("确定从上传队列中删除当前图片?")) {
selFiles.value.splice(index,1);
}
}
//上传
const upload = () => {
//判断是否选中文件
var file = selFiles.value[0].file;
if (typeof(file) === "undefined") {
alert("请在上传前先选中文件!");
return;
}
// 创建一个表单数据
var data = new FormData();
//遍历文件，添加到form
for( var i=0;i<selFiles.value.length; i++ ){
let fileOne = selFiles.value[i].file;
data.append("img[]",fileOne);
}
let url = "/api/news/multiimgadd";
//axios上传文件
axios({

data:data,
headers:{'Content-Type': 'multipart/form-data'},
}).then((res) => {

let data = res.data.data;
let imageUrl = data.urls;
alert("success:image:"+imageUrl);
} else {
alert("error:"+res.data.msg);
}
}
).catch(err=>{
alert('网络错误:'+err.message);
});
}
return {
handleFile,
selFiles,
delqueue,
upload,

}
}
</script>
<style scoped>
</style>

三，后端php代码:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
//多图片上传
public function multiImgAdd(Request $request) {
if ($request->hasFile('img')) {
$str = "";
//遍历文件
foreach ($request->file('img') as $index=> $e) {
//得到扩展名
$ext = $e->getClientOriginalExtension();
$filename = time().rand().".".$ext;
$baseDir = "/var/www/html/digImage";
//保存图片到指定目录
$e->move($baseDir,$filename);
//返回url
$url = "http://192.168.219.6/digImage/".$filename;
if ($str == '') {
$str = $url;
} else {
$str .= ";".$url;
}
}
return Result::Success(['urls'=>$str]);
}else{
// 回到上一个页面
//return back();
return Result::ErrorCode(10024,'图片文件未上传');
}
}
