.Net Core使用layui多文件上传
本文实例为大家分享了.Net Core使用layui多文件上传功能的具体代码，供大家参考，具体内容如下
这段时间刚刚接触了.NET Core,工作要求，从0开始，给用户开发了一个小型的内部系统。用户提出需求，要求能实现多文件上传，上传不同位置的文件，可以删除。
找来找去还是layui的文件上传符合审美，不多废话上代码
1.前端页面
<div class="layui-upload">
<button type="button" class="layui-btn layui-btn-normal" id="testList">Search</button>
<div class="layui-upload-list">
<table class="layui-table">
<thead>
<tr>
<th>File Name</th>
<th>Size</th>
<th>Status</th>
<th>Action</th>
</tr>
</thead>
<tbody id="demoList"></tbody>
</table>
</div>
<button type="button" class="layui-btn" id="testListAction" onclick="noFile()">Upload</button>
</div>
script部分
<script>
layui.use('upload', function () {
var upload = layui.upload;
var demoListView = $('#demoList')
, uploadListIns = upload.render({
elem: '#testList'
, url: '你的文件上传接口'
, accept: 'file'
, multiple: true
, size: 30000
, auto: false
, bindAction: '#testListAction'
, choose: function (obj) {
var files = this.file = obj.pushFile(); //将每次选择的文件追加到文件队列
console.log(uploadListIns);
//读取本地文件
obj.preview(function (index, file, result) {
var tr = $(['<tr id="upload-' + index + '">'
, '<td>' + file.name + '</td>'
, '<td>' + (file.size / 1014).toFixed(1) + 'kb</td>'
, '<td>Wait to upload</td>'
, '<td>'
, '<button class="layui-btn layui-btn-xs demo-reload layui-hide">重传</button>'
, '<button class="layui-btn layui-btn-xs layui-btn-danger demo-delete">Delete</button>'
, '</td>'
, '</tr>'].join(''));
//删除
tr.find('.demo-delete').on('click', function () {
delete files[index]; //删除对应的文件
tr.remove();
uploadListIns.config.elem.next()[0].value = ''; //清空 input file 值，以免删除后出现同名文件不可选
//console.log(files);
});
demoListView.append(tr);
});
}
, done: function (res, index, upload) {
if (res.code == 0) //上传成功
var tr = demoListView.find('tr#upload-' + index)
, tds = tr.children();
tds.eq(2).html('<span style="color: #5FB878;">Success</span>');
tds.eq(3).html(''); //清空操作
return delete this.files[index]; //删除文件队列已经上传成功的文件
}
, error: function (index, upload) {
}
});
})
</script>
到这里的话其实就是从官网copy下来的哈哈哈，接下来的就是重点啦
2.后端部分
这里是controller部分
public async Task<IActionResult> UploadFiles(List<IFormFile> file)
{
EditorDataResult editorResult = new EditorDataResult();
foreach (var formFile in file)
{
if (formFile.Length > 0)
{
FileInfo fi = new FileInfo(formFile.FileName);
string ext = fi.Extension;
var orgFileName = fi.Name;
var newFileName = Guid.NewGuid() + ext;
var uploads = Path.Combine(_hostingEnvironment.WebRootPath, "你想要上传到文件夹");
var filePath = Path.Combine(uploads, newFileName);
using (var stream = new FileStream(filePath, FileMode.Create))
{
await formFile.CopyToAsync(stream);
}
editorResult.code = 0;
}
else
{
editorResult.code = 1;
}
}
JavaScriptSerializer jss = new JavaScriptSerializer();
string data = jss.Serialize(editorResult);//转换为Json格式!
return Json(data);
}
model部分 主要就是回调json数据给layui
namespace LayuiMvc.Common.Result
{
public class EditorDataResult
{
public int code { get; set; }
public string msg { get; set; }
public Dictionary<string, string> data { get; set; }
}
}
到这边基本上文件上传已经done了
