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。我进行的第一个 Azure API 调用 - CloudQueue.CreateIfNotExist() - 导致异常：(407) 需要代理身份验证。我尝试了以下操作：

• 添加了 > defaultProxy 元素添加到 app.config 中，但它似乎不起作用（参考：http://geekswithblogs.net/mnf/archive/2006/03/08/71663.aspx）。
• 我配置了“ISA Server 的 Microsoft 防火墙客户端”，但这也没有帮助。
• 按照此处的建议使用自定义代理处理程序： http://dunnry.com/blog/ 2010/01/25/SupportingBasicAuthProxies.aspx。我无法正常工作 - 出现配置初始化异常。

根据 MSDN，仅在开发存储的情况下才能在连接字符串中指定 HTTP 代理服务器（请参阅 http://msdn.microsoft.com/en-us/library/ee758697.aspx):
UseDevelopmentStorage=true;DevelopmentStorageProxyUri=http://myProxyUri

有没有办法通过连接到Azure存储代理服务器？

Answer 1

我实际上发现不需要自定义代理解决方案。

将以下内容添加到 app.config （就在 之前）对我来说很有效：

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

Answer 2

自定义代理解决方案（我在原始问题中提到的第三件事）工作得很好。我之前犯的错误是没有按照要求将 元素放在 app.config 中 的开头。这样做后，此处给出的自定义代理解决方案解决了我的问题。

要绕过代理，请像下面一样使用，它按预期工作并且已经过测试。

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#，然后请将以下代码添加到“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>
