The Windows Azure Toolkits – Integrated ACS with iOS、Windows Phone、Android and Windows 8
文/黃忠成
隨著Windows Azure Platform的發展，其支援的平台及語言也越來越多，行動裝置自然也是重點之一，從去年開始，Windows Azure Toolkit for Windows Phone率先推出，
緊接著for iOS與Android版本也釋出了。10個月後的今天，這些Windows Azure Toolkits隨著Windows Azure Platform的發展逐步演進，除了修正了許多Bugs之外，
還加入了新的生力軍：Windows Azure Toolkits for Windows 8。
圖1
這些Toolkits的功能其實都差不多，主要是提供Storage Services(Table、Queue、Blob)存取能力，還有與ACS(Access Control Service)整合的能力，
在新加入的Windows Azure Toolkit for Windows 8中還支援了Service Bus。
本文先將重點擺在ACS部分，其餘的Storage Services部分可請讀者先下載去年Tech Days的投影片及範例，未來我會抽空補充這一部分。
http://www.code6421.com/TechDays2011/Publish.zip
關於ACS
ACS是Windows Azure Platform所提供的服務之一，主要是負責使用者身分驗證的動作，ACS本身是一個中介者，協助應用程式使用不同的Identity Providers(Facebook、
Google、Windows Live、ADFS、Open ID)來進行使用者驗證的動作。
應用程式使用ACS來進行驗證最大的好處在於可允許使用者透過主流的Identity Providers來登入你提供的服務，在現今這個社群導向的年代，使用行動裝置的使用者應該
都至少擁有Facebook、Windows Live、Google、Yahoo中的一個帳號，而ACS支援這些主流社群網站，也就是說你的服務可以不必要求使用者註冊，也不必儲存使用者的帳號密碼，
透過ACS，應用程式只需要取得需要的資料即可(like Email)，也因為不須註冊就可以使用服務，使用者可以跳過繁瑣的註冊動作直接使用服務，這將提升使用者試用你的服務的意願。
另外，ACS也可作為一種Single Sign-On(單一簽入)的解決方案，不過這不在本文的討論範圍。
設定ACS
首先，你得先有Windows Azure帳號才能使用ACS，需要的請至以下網址申請測試帳號(免費的哦)
http://www.windowsazure.com/zh-tw/
有了帳號後，就可到Windows Azure Portal中啟用ACS。
圖2
點選上方的新增來添加一個服務命名空間。
圖3
圖4
於此填入命名空間的名稱及選擇國家/地區，完成後等待此服務空間啟用。
圖5
本文的範例是使用Facebook作為驗證的Identity Provider，所以需要至http://developers.facebook.com/來申請建立一個應用程式(注意，
你必須擁有Facebook帳號及通過手機簡訊驗證才能建立Facebook應用程式)。
圖6
注意App Domains及Website with Facebook Login欄位，此處需填入你的ACS 網站網址，通常是<服務命名空間>.accesscontrol.windows.net。
接著使用瀏覽器開啟https://<服務命名空間>.accesscontrol.windows.net，便可看到類似下圖的畫面。
圖7
點選識別提供者，接著再點選新增。
圖8
此處選擇Facebook應用程式。
圖9
這裡需輸入一個顯示名稱，此處使用Facebook，接著要填入之前建立Facebook的應用程式識別碼及密碼(應用程式密鑰)。
接著點選左方的信賴憑證者應用程式來新增一個應用程式。
圖7
圖10
此處需輸入顯示名稱及領域，領域必須是一個URL，可使用localhost(這只是一個識別名稱)，接著選擇權杖格式為SWT，下方會出現要求產生憑證的部分。
圖11
此處只須點選產生後按下儲存即可，這樣就算完成ACS整合Facebook Identity Provider的部分了，接下來就是開始透過應用程式連接ACS來進行與Facebook的整合驗證。
Windows Phone 7
透過Windows Azure Toolkit for Windows Phone，應用程式可直接使用其提供的Library&Controls來存取Storage Services及ACS，讀者可以由以下網址下載。
要連接ACS，只需建立一個新的Windows Phone Application專案，並將WAToolkitForWP7\Samples\WP7.1\Libraries\SL.Phone.Federation目錄下的.csproj加到方案中，
再由Windows Phone Application專案加入對SL.Phone.Federation的參考即可。
圖12
接著修改App.xaml，加入以下內容。
圖13
建立一個新的頁面(SignInControl)，並加入Azure Tookit所提供的Login控制項。
圖14
Realm需對應信賴者憑證應用程式中的領域設定。
圖10
ServiceNamespace則對應ACS命名空間(我們的ACS網址是demoacs3.accesscontrol.windows.net，所以此處為demoacs3)。
修改主頁面(MainPage.xaml)。
……………………
using SL.Phone.Federation.Utilities;
namespace DemoACS
{
public partial class MainPage : PhoneApplicationPage
{
RequestSecurityTokenResponseStore _rstrStore = null;
// Constructor
public MainPage()
{
InitializeComponent();
_rstrStore = (RequestSecurityTokenResponseStore)App.Current.Resources["rstrStore"];
}
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
if (!_rstrStore.ContainsValidRequestSecurityTokenResponse())
{
NavigationService.Navigate(new Uri("/SignInControl.xaml", UriKind.Relative));
}
else
{
textBlock1.Text = "thanks for your login";
}
}
}
}
完成後測試，將可看到以下的畫面。
圖15
圖16
輸入帳密後，正確的話就可看到圖17。
圖17
Android
Windows Azure Toolkit for Android可由以下網址下載。
https://github.com/WindowsAzure-Toolkits/wa-toolkit-android
下載後解壓，透過Eclipse將WAToolkitForAndroid\library\accesscontrol Import到現在使用的Workspace，接著建立一個Android Application Project，Build SDK請選擇Android 2.2，
修改此Project的Properties中Android頁面設定，將accesscontrol這個Project新增為Library。
圖18
修改Project中的AndroidManifest.xml如下。
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.demoacsb"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SuccessLoginActivity"
android:label="@string/title_activity_success_login" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".UnsuccessLogin"
android:label="@string/title_activity_unsuccess_login" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.microsoft.samples.windowsazure.android.accesscontrol.login.AccessControlLoginActivity" android:label="@string/app_name" />
<activity android:name="com.microsoft.samples.windowsazure.android.accesscontrol.login.AccessControlWebAuthActivity" android:label="@string/app_name" />
</application>
</manifest>
加入Resource Strings。
/res/values/strings.xml
<resources>
<string name="app_name">DemoACSB</string>
<string name="hello_world">Hello world!</string>
<string name="menu_settings">Settings</string>
<string name="title_activity_main">MainActivity</string>
<string name="cloud_ready_acs_namespace">demoacs3</string>
<string name="cloud_ready_acs_realm">http://www.code6421.com</string>
<string name="cloud_ready_acs_symmetric_key">9FhZFekCsz1YsWpjdiQxJAbh2AhW3WS/aQ----blx3g=</string>
<string name="title_activity_success_login">SuccessLoginActivity</string>
<string name="title_activity_unsuccess_login">UnsuccessLogin</string>
</resources>
注意cloud_ready_acs_symmetric_key欄位，這裡要放置ACS中的憑證金鑰，另外cloud_ready_acs_realm則是對應信賴者憑證應用程式中的領域設定。
加入兩個Activity。
SuccessLoginActivity.java
package com.example.demoacsb;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;
public class SuccessLoginActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_success_login);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_success_login, menu);
return true;
}
}
/res/layout/activity_success_login.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="@dimen/padding_medium"
android:text="Login OK"
tools:context=".SuccessLoginActivity" />
</RelativeLayout>
UnsuccessLogin.java
package com.example.demoacsb;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;
public class UnsuccessLogin extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_unsuccess_login);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_unsuccess_login, menu);
return true;
}
}
/res/layout/activity_unsuccess_login.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="@dimen/padding_medium"
android:text="Login Fail"
tools:context=".UnsuccessLogin" />
</RelativeLayout>
在主要的Activity對應的Layout加入一個Button。
res/layout/activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="162dp"
android:text="Login" />
</RelativeLayout>
鍵入以下的程式碼。
MainActivity.java
package com.example.demoacsb;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.support.v4.app.NavUtils;
import com.microsoft.samples.windowsazure.android.accesscontrol.core.IdentityProvidersRepository;
import com.microsoft.samples.windowsazure.android.accesscontrol.login.AccessControlLoginActivity;
import com.microsoft.samples.windowsazure.android.accesscontrol.login.AccessControlLoginContext;
import com.microsoft.samples.windowsazure.android.accesscontrol.swt.SimpleWebTokenHandler;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button manualLoginButton = (Button) findViewById(R.id.button1);
manualLoginButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
doManualLogin();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
private void doManualLogin() {
if (!validateACSConfiguration()) return;
String acsNamespace = getString(R.string.cloud_ready_acs_namespace);
String acsRealm = getString(R.string.cloud_ready_acs_realm);
String acsSymmKey = getString(R.string.cloud_ready_acs_symmetric_key);
Intent intent = new Intent(this, AccessControlLoginActivity.class);
AccessControlLoginContext loginContext = new AccessControlLoginContext();
loginContext.IdentityProviderRepository = new IdentityProvidersRepository(
String.format(
"https://%s.accesscontrol.windows.net/v2/metadata/IdentityProviders.js?protocol=javascriptnotify&realm=%s&version=1.0",
acsNamespace, acsRealm));
loginContext.AccessTokenHandler = new SimpleWebTokenHandler(acsRealm, acsSymmKey);
loginContext.SuccessLoginActivity = SuccessLoginActivity.class;
loginContext.ErrorLoginActivity = com.example.demoacsb.UnsuccessLogin.class;
intent.putExtra(AccessControlLoginActivity.AccessControlLoginContextKey, loginContext);
startActivity(intent);
}
private boolean validateACSConfiguration() {
String acsNamespace = getString(R.string.cloud_ready_acs_namespace);
String acsRealm = getString(R.string.cloud_ready_acs_realm);
String acsSymmKey = getString(R.string.cloud_ready_acs_symmetric_key);
if (isValidConfigurationValue(acsNamespace) && isValidConfigurationValue(acsRealm) && isValidConfigurationValue(acsSymmKey))
return true;
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setTitle("Configuration Error");
dialog.setCanceledOnTouchOutside(true);
dialog.setCancelable(true);
dialog.setMessage("Please review your ACS configuration and try again");
dialog.show();
return false;
}
private boolean isValidConfigurationValue(String value) {
return !(value.startsWith("{") || value.trim() == "");
}
}
完成後執行前，請特別注意要使用Android 2.2的模擬器，因為2.2以上的模擬器在WebView物件處理上有Bugs，無法處理Scripting Injection部分。

iOS
Windows Azure Toolkit for iOS 可由以下網址下載。
https://github.com/WindowsAzure-Toolkits/wa-toolkit-ios/
下載後須先透過XCode 開啟WAToolkitForIOS\library\watoolkitios-lib.xcodeproj這個Project，然後進行編譯後取得.a及對應的.h檔案。
接著透過XCode建立一個Single View的Project，先取名為DemoACS，將先前取得的.h檔案複製到此Project目錄下的watoolkitios-lib目錄中，並將.a檔案新增進此專案中，
接著修改DemoACS-Prefix.pch加入import。
DeniACS-Prefix.pch
//
// Prefix header for all source files of the 'DemoACS' target in the 'DemoACS' project
//
#import
#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif
#ifdef __OBJC__
#import
#import
#import "watoolkitios-lib/WAToolkit.h"
#endif
然後修改MainStoryboard_iPhone.storyboard加入一個Button，並修改DemoACSViewController.h加入一個method。
DemoACSViewController.h
//
// DemoACSViewController.h
// DemoACS
//
// Created by on 12/7/6.
// Copyright 2012年 __MyCompanyName__. All rights reserved.
//
#import
@interface DemoACSViewController : UIViewController {}
- (IBAction)loginAction:(id)sender;
@end
緊接著修改DemoACSViewController.m。
//
// DemoACSViewController.m
// DemoACS
//
// Created by on 12/7/6.
// Copyright 2012年 __MyCompanyName__. All rights reserved.
//
#import "DemoACSViewController.h"
NSString * const ACSNamespace = @"demoacs3";
NSString * const ACSRealm = @"http://www.code6421.com";
NSString * const NameIdentifierClaim = @"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier";
NSString * const AccessTokenClaim = @"http://www.facebook.com/claims/AccessToken";
@implementation DemoACSViewController- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{ [super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
- (IBAction)loginAction:(id)sender {
WACloudAccessControlClient *acsClient = [WACloudAccessControlClient accessControlClientForNamespace:ACSNamespace realm:ACSRealm];
[acsClient showInViewController:self allowsClose:NO withCompletionHandler:^(BOOL authenticated) {
if (!authenticated) {
UIAlertView *dialog = [[UIAlertView alloc] initWithTitle:@"Info" message:@"Login Fail" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[dialog show];
} else {
UIAlertView *dialog = [[UIAlertView alloc] initWithTitle:@"Info" message:@"Login Successed" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[dialog show];
}
}];
}
@end
最後透過Interface Builder把loginAction與畫面上的Button建立繫結，然後修改此Project的Build Settings中的Other Link Flags為 -ObjC -all_load 即可。

Windows 8
Windows Azure Toolkit for Windows 8可由下列網址下載。
http://watwindows8.codeplex.com/
不過此版本目前僅支援Consumer Preview及Visual Studio 2012 Beta，要動點手腳才能正常使用，另外，其ACS部分僅提供使用protocol為WS-Federation模式的驗證，跟我們前面使用
javascriptnotify為protocol的方式不同，前者目前需要一個收取claims的網站，因此我修改了Toolkit中的ACS部分，使其支援javascriptnotify驗證模式(載點在文末)。
請先下載我所提供的ACS Library，然後建立一個Windows Metro style App 專案，加入兩個類別。

public class ProvidersInfoEventArgs : EventArgs
{
public ProvidersInfoEventArgs(IIdentityProvidersInfo info)
{
this.ProvidersInfo = info;
}
