一个Azure的托管网站的文件夹中创建文件 [英] Create a file in a folder of an Azure-hosted website
问题描述
我需要从Azure的Blob存储的文件复制到我的Azure的内容文件夹中托管网站,而我努力使这项工作!任何帮助将非常AP preciated。
在code ++工程,我的本地服务器上的罚款,但在Azure托管时失败。
I need to copy a file from Azure Blob Storage to the "contents" folder of my Azure hosted website, and I am struggling to make this work ! Any help would be very much appreciated. The code works fine on my local server, but fails when hosted on Azure.
下面是我的功能:
public bool CopyFromAzure(string myContainer, string fileName, string filePath)
{
// Retrieve storage account from connection string.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);
// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference(myContainer);
// Retrieve reference to a blob named "myblob".
CloudBlockBlob blockBlob = container.GetBlockBlobReference(fileName);
try
{
// Save blob contents to a file.
// --> here is where an error happens !! on System.IO.File.Create
// The value of "filePath" is: F:\sitesroot\0\Content\tmp\file_2cfe0a3d-fa7a-4ab4-a665-cdebd90567d4.pdf
using(FileStream fs= System.IO.File.Create(@filePath))
{
blockBlob.DownloadToStream(fs);
}
}
catch (Exception e)
{
return false;
}
return true;
}
问:可以将此链接到安全preferences在Azure中或在我的网站配置
Question: can this be linked to Security preferences in Azure or in my website configuration?

推荐答案
问题终于解决了。
出于某种原因,写权限不允许对Azure的分布的子文件夹(例如:/内容/ tmp目录)。我简单地写我的文件到项目的根解决了PB。
Problem finally solved. For some reason, write rights were not allowed on subfolders of the Azure distribution (ie: /Content/tmp). I solved the pb by simply writing my files to the root of the project.
在code的工作:
string filePath = HttpContext.Current.Server.MapPath("~/" + fileName);
using (FileStream fs = System.IO.File.OpenWrite(filePath))
{
blockBlob.DownloadToStream(fs);
}
