我正在尝试使用ng-file-upload上传文件并将blob保存到数据库,如上一个问题Ng-File-Upload to Save PDF Blob to Database
我相信我有“正确”的代码来完成任务,但现在的问题是我无法获得代码来“击中”ApiController中的方法。如果我将该方法放在常规异步控制器中,它会找到它(但是我不能使用所需的一半代码,因为它不起作用,除非它在一个继承自ApiController的控制器中),但它不会在ApiController中找到相同的方法。我错过了什么?
以下是角度控制器代码:
angular.module('myModule').controller('DocumentCtrl', function ($scope, $interval, $window, $filter, $q, $timeout, Upload, $http) {
$scope.uploadPic = function (file) {
file.upload = Upload.upload({
url: '/SSQV4/SSQV5/Document/UploadEMRDocument',
method: 'POST',
data: { file: file }
})
}
}) 这是MVC控制器代码:
public class DocumentController : ApiController
{
public async Task<IHttpActionResult> UploadEMRDocument()
{
try
{
var provider = new MultipartMemoryStreamProvider();
await Request.Content.ReadAsMultipartAsync(provider);
var f = provider.Contents.First(); // assumes that the file is the only data
if (f != null)
{
var filename = f.Headers.ContentDisposition.FileName.Trim('\"');
filename = Path.GetFileName(filename);
var buffer = await f.ReadAsByteArrayAsync();
//buffer now contains the file content,
//and filename has the original filename that was uploaded
//do some processing with it (e.g. save to database)
}
else
{
return BadRequest("Attachment failed to upload");
}
}
catch (Exception ex)
{
return BadRequest(ex.Message);
}
return Ok();
}
}
我假设这是某种路由问题,但我不确定。非常感谢任何帮助!

上传正在使用Http POST发送文件,但是,您没有指定您的操作方法应该监听POST。只需添加HttpPost
属性:
[HttpPost]
public async Task<IHttpActionResult> UploadEMRDocument()

我需要将网址更改为
url: '/SSQV4/SSQV5/api/Document/UploadEMRDocument'
现在它命中了它。感谢您的帮助Nava-Prev.Queti!
