Web Api를 사용하여 Azure blob에 파일 업로드

Question

Azure BLOB에 파일을 업로드해야합니다. 아래 그림과 같이 시도했습니다.하지만 작동하지 않습니다. 내가 잘못했음을 알았습니다. 이전에는 파일 시스템을 사용했습니다. 저장 이미지.하지만 이제는 Blob에 저장해야합니다.

참고 :blockBlob.UploadFromStream(filestream);//after this point it doesn't work

웹 API 광고 방법

[HttpPost] 
public async Task<HttpResponseMessage> AddPictures() 
    { 
     if (!Request.Content.IsMimeMultipartContent()) 
     { 
      Request.CreateResponse(HttpStatusCode.UnsupportedMediaType); 
     } 

     var newImageName = string.Empty; 
     var path = System.Web.Hosting.HostingEnvironment.MapPath("~"); 
     var provider = GetMultipartProvider(); 
     await Request.Content.ReadAsMultipartAsync(provider); 

     foreach (var r in provider.FileData) 
      { 
       var uploadedFileInfo = new FileInfo(r.LocalFileName); 
       var originalFileName = GetDeserializedFileName(r); 
       var extension = Path.GetExtension(originalFileName); 
       if (extension == null) continue; 

       var ext = extension.ToLower(); 
       var guid = Guid.NewGuid().ToString(); 
       newImageName = guid + ext; 

       var storageAccount = new CloudStorageAccount(new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials("pictures", "key"),true); 

       // Create the blob client. 
       var blobClient = storageAccount.CreateCloudBlobClient(); 

       // Retrieve reference to a previously created container. 
       var container = blobClient.GetContainerReference("ippictures"); 

       // Retrieve reference to a blob named "myblob". 
       var blockBlob = container.GetBlockBlobReference(newImageName); 

       using (var filestream = File.OpenRead(r.LocalFileName)) 
       { 
       blockBlob.UploadFromStream(filestream);//after this point it doesn't work 
       } 
       File.Delete(r.LocalFileName); 

      } 
       return Request.CreateResponse(HttpStatusCode.OK, new { newImageName }); 
     } 

AngularJS와 방법

  //to add Pictures 
      vm.addPictures = function ($files, errFiles) { 
       vm.upload = []; 
       vm.errFiles = errFiles; 
       if ($files && $files.length) { 
        //$files: an array of files selected, each file has name, size, and type 
        for (var i = 0; i < $files.length; i++) { 
         var $file = $files[i]; 
         (function (index) { 
          vm.upload[index] = upload.upload({ 
           url: "/api/Picture/AddPictures", 
           method: "POST", 
           data: {}, 
           file: $file 
          }).progress(function() { 
          }).success(function (data) { 
           vm.pictureList.push({ 
            id: vm.pictureList.length + 1, 
            url: '/common/pictures/' + data.newImageName, 
            note: '', 
            isSelected: true, 
           }); 

          }).error(function() { 
          }); 
         })(i); 
        } 
       } 
      };

예외 메시지 :

Answer 1

귀하의 스토리지 계정이 ippictures라고

The remote server returned an error: (404) Not Found.

물방울 용기,하지만 컨테이너는 ippictures라고합니다. 코드에서는 blobClient.GetContainerReference("ippictures"); 대신 blobClient.GetContainerReference("ip-pictures");으로 할

당신은 지정된 컨테이너가 존재하는지 여부를 확인하여 이러한 상황 종류의 안전망을 추가 할 수

:

var container = blobClient.GetContainerReference("ip-pictures"); 
container.CreateIfNotExists()
