WindowsAzure 之 Storage

                                      WindowsAzure 之 Storage

1.      建立Storage account

a.      使用Windows Azure 帳號(LiveID)登陸 https://windows.azure.com

b.     點擊 瀏覽節點 ”Hosted Service, Storage Accounts & CDN”

c.      點擊二級瀏覽節點  “Storage Account”

d.     點擊 “NewStorage Account”

系統將顯示正在建立，大概需要10分鐘左右才能ready:

建立成功後如下：

 

e.     查看access key(存取金鑰), 點擊view 按鈕:

注意以上的密鑰是訪問Windows Azure Storage空間的唯一認證標識，切記不要泄漏，下面的實驗中我將會示範如何使用以上密鑰。

 

Windows Azure storage 三種主要的資料存放區方式：Bolb 隱藏檔，圖片等資料，Table儲存 本結構化的資料， Queue 儲存一些需要和其他的應用程式 交換資訊，存在Queue中的資料預設七天內會清除。

 

2.      在程式中配置storage 串連資訊

a.      在VS2010選中WebRole節點, 右擊選擇properties(屬性)

b.     點擊Settings(設定) 選項卡

 

c.      點擊”Add Setting”, 將Name改為StorageAccount,將Type改為 “Connection String”, 並點擊改行的 ”…”

d.     填寫Storage Account資訊，選擇Enter storageaccount credential , 填寫Account Name, Account Key(Primary accesskey 或 Second access key), 選擇 Use defaultHTTP endpoints, 點OK完成設定

 

3.     第一個訪問Storage 的程式(功能為建立一個名為pic的Bolb容器，容器可以理解為檔案夾) 

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using Microsoft.WindowsAzure;using Microsoft.WindowsAzure.ServiceRuntime;using Microsoft.WindowsAzure.StorageClient;using System.Threading;namespace WebRole1{    public partial class TestStroage : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            if (!this.IsPostBack)            {                this.TestBlob();            }        }        public void TestBlob()        {            CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) =>            {                configSetter(RoleEnvironment.GetConfigurationSettingValue(configName));                RoleEnvironment.Changed += (anotherSender, arg) =>                {                    if (arg.Changes.OfType<RoleEnvironmentConfigurationSettingChange>()                        .Any((change) => (change.ConfigurationSettingName == configName)))                    {                        if (!configSetter(RoleEnvironment.GetConfigurationSettingValue(configName)))                        {                            RoleEnvironment.RequestRecycle();                        }                    }                };            });            var storageAccount = CloudStorageAccount.FromConfigurationSetting("StroageAccount");            CloudBlobClient blobClient = new CloudBlobClient(storageAccount.BlobEndpoint, storageAccount.Credentials);            CloudBlobContainer blobContainer = blobClient.GetContainerReference("pics");            BlobRequestOptions requestOption = new BlobRequestOptions();            IAsyncResult result = blobContainer.BeginCreateIfNotExist(requestOption, CreateContainerIfNotExistsCallback, blobContainer);            while (!result.IsCompleted)            {                Thread.Sleep(1000);            }                   }        public void CreateContainerIfNotExistsCallback(IAsyncResult result)        {            CloudBlobContainer container = (CloudBlobContainer)result.AsyncState;            //End the operation and indicate whether the container was created.            if (container.EndCreateIfNotExist(result))            {                this.Response.Write("Container created successfully.");            }            else            {                this.Response.Write("Container was not created because a container with that name already exists.");            }        }    }}

以後的博文中本人會逐一舉例說明Bolb,Table , Queue的用法。
