【问题描述】:
在我的项目中,我需要用户上传一个文件,然后将其发送到 Blob 存储。目前,我只能发送已经存储的文件,我需要它来发送用户上传的文件。
这是我目前上传文件的代码,但是我不确定如何修改
使用 (var fileStream = System.IO.File.OpenRead(file))
这样它就从“HttpPostedFile 文件”中获取一个文件
代码中被注释掉的部分是将其存储到我的系统而不是云端的旧版本。
// POST: DocumentUps/Create
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult CreateUpload([Bind(Include = "DocumentId,DocName,creationDate,RevisionNumber,Author,Status,ActivationDate,Attachment,RevisionId")] DocumentUps documentUps, HttpPostedFileBase file)
{
if (ModelState.IsValid)
{
documentUps.RevisionId = documentUps.DocumentId;
documentUps.Username = User.Identity.Name;
documentUps.Attachment = file.FileName;
documentUps.creationDate = DateTime.Now;
documentUps.ActivationDate = DateTime.Now;
documentUps.RevisionNumber = 0;
documentUps.Status = StatusChoice.Draft;
db.DocumentUps.Add(documentUps);
db.SaveChanges();
int id = documentUps.DocumentId;
DocumentUps docsup = db.DocumentUps.Find(id);
documentUps.RevisionId = id;
documentUps.Username = User.Identity.Name;
documentUps.Attachment = documentUps.Attachment;
documentUps.DocumentId = documentUps.DocumentId;
documentUps.creationDate = documentUps.creationDate;
documentUps.ActivationDate = DateTime.Now;
documentUps.RevisionNumber = 0;
documentUps.DocName = documentUps.DocName;
documentUps.Author = documentUps.Author;
documentUps.Status = StatusChoice.Draft;
db.Entry(documentUps).State = EntityState.Modified;
db.SaveChanges();
if (file != null && file.ContentLength > 0)
{
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("filestorageideagen_AzureStorageConnectionString"));
Microsoft.WindowsAzure.StorageClient.CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
Microsoft.WindowsAzure.StorageClient.CloudBlobContainer container = blobClient.GetContainerReference("documentuploader");
Microsoft.WindowsAzure.StorageClient.CloudBlockBlob blob = container.GetBlockBlobReference("TestUpload");
using (var fileStream = System.IO.File.OpenRead(file))
{
blob.UploadFromStream(fileStream);
}
//var fileName = documentUps.DocumentId.ToString() + documentUps.RevisionId.ToString() + Path.GetFileName(file.FileName);
//var path = Path.Combine(Server.MapPath("~/Content/fileHistory"), fileName);
//file.SaveAs(path);
}
