上传文件前端代码如下：
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> <meta charset="utf-8" /> <script src="https://www.jb51.net/js/vue.js"></script> <script src="https://www.jb51.net/js/vue-resource.js"></script> <script src="https://www.jb51.net/asset/js/jquery.js"></script> </head> <body> <div> <input type="file" @change="getFile($event)" /><button @click="upload">上传</button> <div>{{ result }}</div> <div v-show="uping==1">正在上传中</div> </div> <script> new Vue({ el: '#app', data: { upath: '', result: '', uping:0 }, methods: { upload: function () { //console.log(this.upath); var zipFormData = new FormData(); zipFormData.append('filename', this.upath);//filename是键，file是值，就是要传的文件，test.zip是要传的文件名 let config = { headers: { 'Content-Type': 'multipart/form-data' } }; this.uping = 1; this.$http.post('http://localhost:42565/home/up', zipFormData,config).then(function (response) { console.log(response); console.log(response.data); console.log(response.bodyText); var resultobj = response.data; this.uping = 0; this.result = resultobj.msg; }); }, getFile: function (even) { this.upath = event.target.files[0]; }, } }); </script> </body> </html>
后端处理代码如下asp.net mvc的：
public ActionResult Up() { string msg = string.Empty; string error = string.Empty; string result = string.Empty; string filePath = string.Empty; string fileNewName = string.Empty; var files = Request.Files; if (files.Count > 0) { //设置文件名 fileNewName = DateTime.Now.ToString("yyyyMMddHHmmssff") + "_" + System.IO.Path.GetFileName(files[0].FileName); //保存文件 files[0].SaveAs(Server.MapPath("~/Uploads/" + fileNewName)); Thread.Sleep(10 * 1000); } return Json(new { msg = "上传成功", newfilename = fileNewName }, JsonRequestBehavior.AllowGet); }
