来自Azure App Service的Blob存储访问 [英] Blob storage access from Azure App Service

问题描述

我在从App Service移动应用程序(不是MobileService)访问Blob存储时遇到问题.我以前曾运行过MobileService，该服务通过以下方式访问Blob存储:

I have an issue with accessing blob storage from an App Service Mobile App (Not MobileService). I previously have had a MobileService running that accessed the Blob Storage in the following way:

// Set the URI for the Blob Storage service.
Uri blobEndpoint = new Uri(string.Format("https://{0}.blob.core.windows.net", storageAccountName));

// Create the BLOB service client.
CloudBlobClient blobClient = new CloudBlobClient(blobEndpoint,
new StorageCredentials(storageAccountName, storageAccountKey));

更新代码以在新服务上运行仍然没有帮助.数据连接似乎正确:

Updating the code to work on the new service, still did not help. The dataconnection seems correct:

因此请参考以下链接天蓝色配置 | azure连接字符串 | azure开始使用Blob存储.

Therefore referring to these links azure configuration | azure connection string | azure get started blob storage.

我已提取数据连接并实现了MS_AzureStorageAccountConnectionString.我有以下方法来验证是否找到了正确的访问权限:

I have extracted the data connection and have implemented the `MS_AzureStorageAccountConnectionString. I have the following methods to verify the correct access is found:

string tempstorage = "";
try
{
    CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("MS_AzureStorageAccountConnectionString"));
    tempstorage = storageAccount.BlobEndpoint.ToString() + "        " + storageAccount.BlobStorageUri.ToString();

    //Uri blobEndpoint = storageAccount.TableStorageUri.GetUri(StorageLocation.Primary);
}
catch
{
}
string cloud = "";
try
{
    CloudStorageAccount temp = CloudStorageAccount.DevelopmentStorageAccount;
    Uri endPoit = temp.BlobEndpoint;
    string uri = temp.BlobStorageUri.ToString();
    cloud = uri + "           " + endPoit.ToString();
 }
 catch
 {
 }
 return Ok("coud : " + cloud + "       temp storage : " + tempstorage);

返回值:

coud:主要=' http://127.0.0.1:10000/devstoreaccount1 '; Secondary =' http://127.0.0.1:10000/devstoreaccount1-secondary ' http://127.0.0.1:10000/devstoreaccount1 临时存储:

coud : Primary = 'http://127.0.0.1:10000/devstoreaccount1'; Secondary = 'http://127.0.0.1:10000/devstoreaccount1-secondary' http://127.0.0.1:10000/devstoreaccount1 temp storage :

这表明不需要访问Storage emulator.

如何获取Azure online storage的Uri，例如从Azure app service进行访问.

How to get the Uri for the Azure online storage such as to access it from the Azure app service.

基于评论进行更新

我将对云配置的请求解释为azure门户上App Service的应用程序设置.

I interpreted the request for cloud configuration as the application settings for the App Service on the azure portal.

<configuration>
     <connectionStrings>
         <add name="MS_AzureStorageAccountConnectionString" connectionString="DefaultEndpointsProtocol=https;AccountName=Name;AccountKey=key1_from_access_Keys" />
     </connectionStrings>
<configuration>

推荐答案

我尝试使用您的代码来重新创建问题，这就是我所做的:

I tried to re-create the issue using your code, and that is what i done:

1)单击项目=>添加=>添加连接的服务=> Azure存储=>选择您的存储帐户.这样会将所有需要的库和有效的连接字符串安装到您的web.config中.

1) Click on the project => Add => Add Connected Service => Azure Storage => Select your storage account. That will install all of needed libraries and valid connection string into your web.config.

2)我将您的代码复制粘贴到HomeController Index操作中，并能够重新创建问题.基本上，您好像更改了值和变量. 工作代码如下.第一个代码段用于Controller，第二个代码段应在索引视图中.我使用了MVC，您看起来像在使用Web API，应该没有什么区别.

2) I copy-pasted your code into the HomeController Index action and was able to re-create the issue. Basically, looks like you changed the values and variables. The working code is below. The first snippet is for Controller, the second should be in the Index view. I used MVC, and you looks like using Web API, should not make any difference.

string tempstorage = "";
        string cloud = "";
        try
        {
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("allinazure_AzureStorageConnectionString"));
            cloud = storageAccount.BlobEndpoint.ToString() + "        " + storageAccount.BlobStorageUri.ToString();                
        }
        catch
        {
        }

        try
        {
            CloudStorageAccount temp = CloudStorageAccount.DevelopmentStorageAccount;
            Uri endPoit = temp.BlobEndpoint;
            string uri = temp.BlobStorageUri.ToString();
            tempstorage = uri + "           " + endPoit.ToString();
        }
        catch
        {
        }
     ViewBag.LocalStorage = "cloud storage" + cloud;
        ViewBag.CloudStorage = "local storage : " + tempstorage;

        return View();

某处的索引视图:

@ViewBag.LocalStorage
@ViewBag.CloudStorage
