AngularJS向后端ASP.NETAPI控制器上传文件_AngularJS

首先服务端：

public class FilesController : ApiController
{
 //using System.Web.Http
 [HttpPost]
 public async Task Upload()
 {
 if(!Request.Content.IsMimeMultipartContent())
 {
 this.Request.CreateResponse(HttpStatusCode.UnsuportedMediaType);
 }
 
 var provider = GetMultipartProvider();
 var result = await Request.Content.ReadAsMultipartAsync(provider);
 
 //文件名类似"BodyPart_26d6abe1-3ae1-416a-9429-b35f15e6e5d5"这样的格式
 var originalFileName = GetDeserializedFileName(result.FileData.First());
 
 var uploadFileInfo = new FileInfo(result.FileData.First().LocalFileName);
 
 //如果前端无表单数据，这里注销
 var filleUploadObj = GetFormData(result);
 
 var returnData = "ReturnTest";
 return this.Request.CreateResponse(HttpStatusCode.OK, new {returnData});
 }
 
 private MultipartFormDataStreamProvider GetMultipartProvider()
 {
 //图片的上传路径
 var uploadFolder = "~/App_Data/FileUploads";
 
 //获取根路径
 var root = HttpContext.Current.Server.MapPath(uploadFolder);
 
 //创建文件夹
 Directory.CreateDirectory(root);
 return new MultipartFormDataStreamProvider(root);
 }
 
 //从Provider中获取表单数据
 private object GetFormData(MultipartFormDataStreamProvider result)
 {
 if(result.FormData.HasKeys())
 {
 var unescapedFormData = Uri.UnescapeDataString(result.FormData.GetValues(0).FirstOrDefault() ?? String.Empty);
 
 if(!String.IsNullOrEmpty(unescapedFormData))
 {
 return JsonConvert.DeserializeObject(upescapedFormData);
 }
 }
 return null;
 }
 
 //获取反序列化文件名
 private string GetDeserializedFileName(MultipartFileData fileData)
 {
 var fileName = GetFileName(fileData);
 return JsonConvert.DeserializedObject(fileName).ToString();
 }
 
 //获取文件名
 public string GetFileName(MultipartFileData fileData)
 {
 return fileData.Headers.ContentDisposition.FileName;
 }
}

UploadDataModel.cs

public class UploadDataModel
{
 public string testString1{get;set;}
 public string testString2{get;set;}
}
 

客户端主页面：

index.html

引用：

upload.html部分视图页用来接受文件。

upload.html

app.js模块依赖和全局配置。

app.js

控制器提供上传和取消上传的方法。
