新瓶舊酒ASP.NET AJAX(10) - 用戶端腳本程式設計（Sys.Services命名空間下的類）

新瓶舊酒ASP.NET AJAX(10) - 用戶端腳本程式設計（Sys.Services命名空間下的類）

介紹

ASP.NET AJAX的Sys.Services.AuthenticationService類、Sys.Services.ProfileService類、Sys.Services.ProfileGroup類完美地和ASP.NET 2.0的Membership和Profile進行了內建

關鍵

1、Sys.Services.AuthenticationService類的login()方法

    Sys.Services.AuthenticationService.login(userName, password, isPersistent, customInfo, redirectUrl, loginCompletedCallback, failedCallback, userContext);

    ·userName - 使用者名

    ·password - 密碼

    ·isPersistent - 是否跨浏覽器儲存認證資訊（持久保留）

    ·customInfo - 保留字段，可能在将來使用

    ·redirectUrl - 登入成功後重定向到的URL

    ·loginCompletedCallback - 登入成功後的回調函數

    ·failedCallback - 登入失敗後的回調函數

    ·userContext - 使用者上下文

    WebService中與其對應的方法 - public bool Login()

2、登入成功後的回調函數

    function LoginComplete(bool validCredentials, userContext, methodName)

    ·validCredentials - 是否成功通過了驗證

    ·methodName - 調用的方法名

3、Sys.Services.AuthenticationService類的logout()方法

    Sys.Services.AuthenticationService.logout(redirectUrl, logoutCompletedCallback, failedCallback, userContext);

    ·redirectUrl - 登出成功後重定向到的URL

    ·logoutCompletedCallback - 登出成功後的回調函數

    ·failedCallback - 登出失敗後的回調函數

    WebService中與其對應的方法 - public void Logout()

4、登出成功後的回調函數

    function LogoutComplete(result, userContext, methodName)

    ·result - 保留字段，可能在将來使用，始終為null

5、Sys.Services.AuthenticationService類的屬性

    ·defaultLoginCompletedCallback - 登入成功後的回調函數

    ·defaultLogoutCompletedCallback - 登出成功後的回調函數

    ·defaultFailedCallback - 登入或登出失敗後的回調函數

    ·isLoggedIn - 目前使用者是否已經登入

    ·path - authentication service路徑

    ·timeout - 逾時時間

6、Sys.Services.ProfileService類的load()方法

    Sys.Services.ProfileService.load(propertyNames, loadCompletedCallback, failedCallback, userContext);

    ·propertyNames - Profile屬性名稱數組

    ·loadCompletedCallback - 成功後的回調函數

    ·failedCallback - 失敗後的回調函數

    WebService中與其對應的方法 - public IDictionary<string, object> GetAllPropertiesForCurrentUser()和public IDictionary<string, object> GetPropertiesForCurrentUser(string[] properties)

7、讀取Profile成功後的回調函數

    function onLoadCompleted(numProperties, userContext, methodName)

    ·numProperties - 傳回的Profile屬性個數

8、Sys.Services.ProfileService類的save()方法

    Sys.Services.ProfileService.load(propertyNames, saveCompletedCallback, failedCallback, userContext);

    ·saveCompletedCallback - 成功後的回調函數

    ·WebService中與其對應的方法 - public int SetPropertiesForCurrentUser(IDictionary<string, object> values)

9、儲存Profile成功後的回調函數

    onSaveCompleted(numProperties, userContext, methodName)

    ·numProperties - 儲存的Profile屬性個數

10、Sys.Services.ProfileService類的屬性

    ·讀取或設定某個Profile的屬性要這麼寫 - Sys.Services.ProfileService.properties.FieldName; 

    ·defaultLoadCompletedCallback - 讀取Profile成功後的回調函數

    ·defaultSaveCompletedCallback - 儲存Profile成功後的回調函數

    ·defaultFailedCallback - 讀取或儲存Profile失敗後的回調函數

    ·path - profile service路徑

11、Sys.Services.ProfileGroup類

    ·定義一個Profile組（同時需要在Web.config中定義）

12、登入或登出失敗、讀取或儲存Profile失敗後的回調函數

    function onFailed(error, userContext, methodName)

    ·error - Sys.Net.WebServiceError對象

13、如果要自動調用相關服務的話，則需要在web.config中的<configuration />節點下增加類似如下的配置

<webServices> 

        <authenticationService enabled="true" requireSSL="false"/> 

        <profileService enabled="true"    

                readAccessProperties="Age, Salary" 

                writeAccessProperties="Age, Salary"    

        /> 

</webServices>
