通过代理服务器连接到Azure存储帐户

Question

我的“LocalClient”应用程序位于HTTP代理服务器（ISA）后面的公司LAN中。我做的第一个Azure API调用 - CloudQueue.CreateIfNotExist() - 会导致一个异常：（407）需要代理验证。我尝试以下操作：

• 添加了<System.Net> defaultProxy元素的App.config，但它似乎并没有工作（参考：http://geekswithblogs.net/mnf/archive/2006/03/08/71663.aspx）。
• 我配置了'用于ISA服务器的Microsoft防火墙客户端'，但这也没有帮助。
• 使用此处建议的自定义代理处理程序：http://dunnry.com/blog/2010/01/25/SupportingBasicAuthProxies.aspx。我无法得到这个工作 - 获取配置初始化异常。

按照MSDN，HTTP代理服务器，可以在连接字符串中只在开发存储的情况下规定（见http://msdn.microsoft.com/en-us/library/ee758697.aspx）：
UseDevelopmentStorage=true;DevelopmentStorageProxyUri= http://myProxyUri

有什么方法来连接到Azure存储通代理服务器？

Answer 1

定制代理解决方案（我在原始问题中提到的第三件事）完美地工作。我之前所做的错误不是根据需要将<configSections>元素放置在app.config的<configuration>开头。在这样做，给定的代理解决方案here解决了我的问题。

Answer 2

我确实发现自定义代理解决方案不是必需的。

加入以下的app.config（只是</configuration>前）为我做的伎俩：

<system.net> 
<defaultProxy enabled="true" useDefaultCredentials="true"> 
<proxy usesystemdefault="true" /> 
</defaultProxy> 
</system.net>

若要通过代理，那么请使用如下，它按预期工作，并同一直测试。

public class AzureUpload { 

    // Define the connection-string with your values 
    /*public static final String storageConnectionString = 
     "DefaultEndpointsProtocol=http;" + 
     "AccountName=your_storage_account;" + 
     "AccountKey=your_storage_account_key";*/ 
    public static final String storageConnectionString = 
      "DefaultEndpointsProtocol=http;" + 
      "AccountName=test2rdrhgf62;" + 
      "AccountKey=1gy3lpE7Du1j5ljKiupjhgjghjcbfgTGhbntjnRfr9Yi6GUQqVMQqGxd7/YThisv/OVVLfIOv9kQ=="; 

    // Define the path to a local file. 
    static final String filePath = "D:\\Project\\Supporting Files\\Jar's\\Azure\\azure-storage-1.2.0.jar"; 
    static final String file_Path = "D:\\Project\\Healthcare\\Azcopy_To_Azure\\data"; 

    public static void main(String[] args) { 
     try 
     { 
      // Retrieve storage account from connection-string. 
      //String storageConnectionString = RoleEnvironment.getConfigurationSettings().get("StorageConnectionString"); 
      //Proxy httpProxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("132.186.192.234",8080)); 
      System.setProperty("http.proxyHost", "102.122.15.234"); 
      System.setProperty("http.proxyPort", "80"); 
      System.setProperty("https.proxyUser", "ad001\\empid001"); 
      System.setProperty("https.proxyPassword", "pass!1"); 
      // Retrieve storage account from connection-string. 
      CloudStorageAccount storageAccount = CloudStorageAccount.parse(storageConnectionString); 

      // Create the blob client. 
      CloudBlobClient blobClient = storageAccount.createCloudBlobClient(); 


      // Get a reference to a container. 
      // The container name must be lower case 
      CloudBlobContainer container = blobClient.getContainerReference("rpmsdatafromhospital"); 

      // Create the container if it does not exist. 
      container.createIfNotExists(); 

      // Create a permissions object. 
      BlobContainerPermissions containerPermissions = new BlobContainerPermissions(); 

      // Include public access in the permissions object. 
      containerPermissions.setPublicAccess(BlobContainerPublicAccessType.CONTAINER); 

      // Set the permissions on the container. 
      container.uploadPermissions(containerPermissions); 

      // Create or overwrite the new file to blob with contents from a local file. 
      /*CloudBlockBlob blob = container.getBlockBlobReference("azure-storage-1.2.0.jar"); 
      File source = new File(filePath); 
      blob.upload(new FileInputStream(source), source.length());*/ 

      String envFilePath = System.getenv("AZURE_FILE_PATH"); 

      //upload list of files/directory to blob storage 
      File folder = new File(envFilePath); 
      File[] listOfFiles = folder.listFiles(); 

      for (int i = 0; i < listOfFiles.length; i++) { 
       if (listOfFiles[i].isFile()) { 
       System.out.println("File " + listOfFiles[i].getName()); 

       CloudBlockBlob blob = container.getBlockBlobReference(listOfFiles[i].getName()); 
       File source = new File(envFilePath+"\\"+listOfFiles[i].getName()); 
       blob.upload(new FileInputStream(source), source.length()); 
       System.out.println("File " + listOfFiles[i].getName()+ " upload successful"); 

       } 
       //directory upload 
       /*else if (listOfFiles[i].isDirectory()) { 
       System.out.println("Directory " + listOfFiles[i].getName()); 

       CloudBlockBlob blob = container.getBlockBlobReference(listOfFiles[i].getName()); 
       File source = new File(file_Path+"\\"+listOfFiles[i].getName()); 
       blob.upload(new FileInputStream(source), source.length()); 
       }*/ 
      } 

     }catch (Exception e) 
     { 
      // Output the stack trace. 
      e.printStackTrace(); 
     } 
    } 
} 

.NET或C＃，那么请添加以下代码 “的App.config”

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <startup> 
     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> 
    </startup> 

    <system.net> 
    <defaultProxy enabled="true" useDefaultCredentials="true"> 
     <proxy usesystemdefault="true" /> 
    </defaultProxy> 
    </system.net> 

</configuration>
