新瓶旧酒ASP.NET AJAX(10) - 客户端脚本编程(Sys.Services命名空间下的类)


作者:webabcd


介绍
ASP.NET AJAX的Sys.Services.AuthenticationService类、Sys.Services.ProfileService类、Sys.Services.ProfileGroup类完美地和ASP.NET 2.0的Membership和Profile进行了集成


关键
1、Sys.Services.AuthenticationService类的login()方法
    Sys.Services.AuthenticationService.login(userName, password, isPersistent, customInfo, redirectUrl, loginCompletedCallback, failedCallback, userContext);
    ·userName - 用户名
    ·password - 密码
    ·isPersistent - 是否跨浏览器保存认证信息(持久保留)
    ·customInfo - 保留字段,可能在将来使用
    ·redirectUrl - 登录成功后重定向到的URL
    ·loginCompletedCallback - 登录成功后的回调函数
    ·failedCallback - 登录失败后的回调函数
    ·userContext - 用户上下文
    WebService中与其对应的方法 - public bool Login()

2、登录成功后的回调函数
    function LoginComplete(bool validCredentials, userContext, methodName)
    ·validCredentials - 是否成功通过了验证
    ·userContext - 用户上下文
    ·methodName - 调用的方法名

3、Sys.Services.AuthenticationService类的logout()方法
    Sys.Services.AuthenticationService.logout(redirectUrl, logoutCompletedCallback, failedCallback, userContext);
    ·redirectUrl - 注销成功后重定向到的URL
    ·logoutCompletedCallback - 注销成功后的回调函数
    ·failedCallback - 注销失败后的回调函数
    ·userContext - 用户上下文
    WebService中与其对应的方法 - public void Logout()

4、注销成功后的回调函数
    function LogoutComplete(result, userContext, methodName)
    ·result - 保留字段,可能在将来使用,始终为null
    ·userContext - 用户上下文
    ·methodName - 调用的方法名

5、Sys.Services.AuthenticationService类的属性
    ·defaultLoginCompletedCallback - 登录成功后的回调函数
    ·defaultLogoutCompletedCallback - 注销成功后的回调函数
    ·defaultFailedCallback - 登录或注销失败后的回调函数
    ·isLoggedIn - 当前用户是否已经登录
    ·path - authentication service路径
    ·timeout - 超时时间

6、Sys.Services.ProfileService类的load()方法
    Sys.Services.ProfileService.load(propertyNames, loadCompletedCallback, failedCallback, userContext);
    ·propertyNames - Profile属性名称数组
    ·loadCompletedCallback - 成功后的回调函数
    ·failedCallback - 失败后的回调函数
    ·userContext - 用户上下文
    WebService中与其对应的方法 - public IDictionary<string, object> GetAllPropertiesForCurrentUser()和public IDictionary<string, object> GetPropertiesForCurrentUser(string[] properties)

7、读取Profile成功后的回调函数
    function onLoadCompleted(numProperties, userContext, methodName)
    ·numProperties - 返回的Profile属性个数
    ·userContext - 用户上下文
    ·methodName - 调用的方法名

8、Sys.Services.ProfileService类的save()方法
    Sys.Services.ProfileService.load(propertyNames, saveCompletedCallback, failedCallback, userContext);
    ·propertyNames - Profile属性名称数组
    ·saveCompletedCallback - 成功后的回调函数
    ·failedCallback - 失败后的回调函数
    ·userContext - 用户上下文
    ·WebService中与其对应的方法 - public int SetPropertiesForCurrentUser(IDictionary<string, object> values)

9、保存Profile成功后的回调函数
    onSaveCompleted(numProperties, userContext, methodName)
    ·numProperties - 保存的Profile属性个数
    ·userContext - 用户上下文
    ·methodName - 调用的方法名

10、Sys.Services.ProfileService类的属性
    ·读取或设置某个Profile的属性要这么写 - Sys.Services.ProfileService.properties.FieldName; 
    ·defaultLoadCompletedCallback - 读取Profile成功后的回调函数
    ·defaultSaveCompletedCallback - 保存Profile成功后的回调函数
    ·defaultFailedCallback - 读取或保存Profile失败后的回调函数
    ·path - profile service路径
    ·timeout - 超时时间

11、Sys.Services.ProfileGroup类
    ·定义一个Profile组(同时需要在Web.config中定义)

12、登录或注销失败、读取或保存Profile失败后的回调函数
    function onFailed(error, userContext, methodName)
    ·error - Sys.Net.WebServiceError对象
    ·userContext - 用户上下文
    ·methodName - 调用的方法名

13、如果要自动调用相关服务的话,则需要在web.config中的<configuration />节点下增加类似如下的配置
<webServices> 
        <authenticationService enabled="true" requireSSL="false"/> 
        <profileService enabled="true"    
                readAccessProperties="Age, Salary" 
                writeAccessProperties="Age, Salary"    
        /> 
</webServices>

Web.config中的相关设置(在<system.web />节点下)
<profile enabled="true"> 
            <properties> 
                <group name="Article"> 
                    <add name="Title" type="System.String" />
