分享一个 asp.net core 多文件分块同时上传的组件

分享一个可多个文件同时上传、断点续传,并实时反馈上传进度的 Asp.Net core 组件。

服务器端


引用 nuget 包:JMS.FileUploader.AspNetCore

然后启用上传组件:

cs 复制代码
            app.UseAuthorization();
            app.MapControllers();

             //启用上传组件,并限制单个文件最大100M
            app.UseJmsFileUploader(1024*102400);
            
            app.Run();

在 Controller 里面,写个 Test 函数,处理上传的文件:

cs 复制代码
    [ApiController]
    [Route("[controller]/[action]")]
    public class MainController : ControllerBase
    {

        [HttpPost]
        public string Test([FromBody] object body)
        {
            var customHeader = Request.Headers["Custom-Header"];
            
            //临时文件路径
            var filepaths = Request.Headers["FilePath"];

            //文件名
            var filenames = Request.Headers["Name"];
            return filenames;
        }
    }

文件上传完毕,保存在临时文件中,Request.Headers["FilePath"] 可以读取这些文件的路径,如果确定要保留这些文件,用 File.Move 把它们移到你的目标文件夹当中;

Request.Headers["Name"] 则是读取文件名。

前端

引入 jms-uploader 组件:

js 复制代码
      import JmsUploader from "jms-uploader"

html 元素:

html 复制代码
    <input id="file1" multiple type="file" />
    <input id="file2" multiple type="file" />
    <button onclick="upload()">
        upload
    </button>
    <div id="info"></div>

javascript 脚本:

js 复制代码
    async function upload() {
        //自定义请求头
        var headers = function () {
            return { "Custom-Header": "test" };
        };

        //提交的body
        var dataBody = {
            name: "abc"
        };

        var uploader = new JmsUploader("http://localhost:5200/main/test", [document.querySelector("#file1").files, document.querySelector("#file2").files], headers, dataBody);

        uploader.setPartSize(1024);//设置分块大小,默认是102400

        uploader.onUploading = function (percent, uploadedSize, totalSize) {
            document.querySelector("#info").innerHTML = percent + "% " + uploadedSize + "," + totalSize;
        };

        var ret = await uploader.upload();
        //上传完毕
        alert(ret);
    }
