新瓶旧酒ASP.NET AJAX(9) - 客户端脚本编程(Sys.Net命名空间下的WebServiceProxy、WebServiceError、Generated Proxy Classes以及调用WebService、PageMethod)


作者:webabcd


介绍
使用ASP.NET AJAX调用WebService(简单类型和复杂对象、JSON和XML)和PageMethod。Sys.Net命名空间下的WebServiceProxy Class、WebServiceError Class、Generated Proxy Classes


关键
1、调用WebService
    ·为WebService类或需要暴露给客户端的WebService方法添加[System.Web.Script.Services.ScriptService]属性
    ·为WebService类中需要暴露给客户端使用的方法添加[System.Web.Services.WebMethod]属性
    ·在ScriptManager控件的Services集合中添加对该WebService的引用
    ·客户端调用方法:[NameSpace].[ClassName].[MethodName](param1, param2, ..., succeededCallback, failedCallback, userContext)
    ·如果用GET方式的话,则在WebService方法添加[System.Web.Script.Services.ScriptMethod(UseHttpGet = true)]属性
    ·用到了复杂类型的话,则在WebService类上添加[System.Web.Script.Services.GenerateScriptType(typeof(TypeName))]属性。另外,该复杂类型必须要有一个无参数的构造函数
    ·禁止将某属性输出到客户端,则在该属性上添加[System.Web.Script.Serialization.ScriptIgnore]属性
    ·以XML方式输出到客户端(一般是JSON),则在WebService方法添加[ScriptMethod(ResponseFormat = ResponseFormat.Xml)]属性。如果要避免ASP.NET AJAX为我们做自动转换,则应该添加[ScriptMethod(ResponseFormat = ResponseFormat.Xml, XmlSerializeString = true)]属性
    ·以XML方式输出到客户端的复杂对象的属性,在属性上添加[System.Xml.Serialization.XmlAttribute]属性(可不写)。若禁止将其输出到客户端,则在属性上添加[System.Xml.Serialization.XmlIgnore]属性。
    ·WebService判断用户是否通过验证 - HttpContext.Current.User.Identity.IsAuthenticated
    ·WebService使用Session - HttpSessionState session = HttpContext.Current.Session;

2、调用PageMethod
    ·ASP.NET页面中的方法需要时Public和Static的
    ·为该方法添加[System.Web.Services.WebMethod]属性
    ·设置ScriptManager控件的EnablePageMethods="true"
    ·客户端调用方法:PageMethods.[MethodName](param1, param2, ..., callbackFunction);

3、WebServiceProxy Class
    var webRequest = Sys.Net.WebServiceProxy.invoke(path, methodName, useHttpGet, parameters, succeededCallback, failedCallback, userContext, timeout);
    ·path - WebService的url
    ·methodName - 调用的方法名
    ·useHttpGet - 是否使用HTTP GET方式
    ·parameters - 参数(示例:{"param1":196610, "param2":"Hello"})
    ·succeededCallback - 调用成功的回调函数
    ·failedCallback - 调用失败的回调函数
    ·userContext - 用户上下文
    ·timeout - 超时时间
    ·返回值 - 相关的WebRequest对象

4、WebServiceError Class
    ·exceptionType - 服务器端异常的具体类型
    ·message - 详细的异常描述信息
    ·stackTrace - 服务器端异常的堆栈跟踪信息
    ·statusCode - 造成异常的HTTP响应的状态码
    ·timedOut - 异常是否是由于网络连接超时造成的

5、Generated Proxy Classes属性
    ·defaultSucceededCallback - 调用成功的回调函数
    ·defaultFailedCallback - 调用失败的回调函数
    ·defaultUserContext - 用户上下文
    ·path - WebService的路径
    ·timeout - 超时时间

6、Generated Proxy Classes(调用Web Service)
    var myServiceProxy = MyNameSpace.MyService();
    myServiceProxy.MyServiceMethod(param1, param2, ..., succeededCallback, failedCallback, userContext);
    ·param - 在前面顺序地写参数
    ·succeededCallback - 调用成功的回调函数
    ·failedCallback - 调用失败的回调函数
    ·userContext - 调用成功的回调函数

7、Generated Proxy Classes(调用成功的回调函数)
    function succeededCallback(result, userContext, methodName) { }
    ·result - 调用WebService的方法后返回的数据
    ·userContext - 用户上下文
    ·methodName - 调用的方法名

8、Generated Proxy Classes(调用失败的回调函数)
    function failedCallback(error, userContext, methodName) { }
    ·error - 调用WebService的方法后返回的数据(Sys.Net.WebServiceError对象)
    ·userContext - 用户上下文
    ·methodName - 调用的方法名
