支持ajax 跨域调用的WCF搭建

1.新建一个"ASP.NET空Web应用程序"项目。

2.新建一个“WCF服务（支持ajax）”。

3.修改WCFAjaxService.svc下的WCFAjaxService.svc.cs文件

如下所示（示例）：

namespace WCF_Ajax跨域调用示例
{
    [ServiceContract(Namespace = "WCF_Ajax跨域调用示例")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    [JavascriptCallbackBehavior(UrlParameterName = jsoncallback")]
    public class WCFAjaxService
    {
        [OperationContract]
        [WebGet(ResponseFormat = WebMessageFormat.Json)]
        public List<UserInfo> GetUser()
        {
            return new List<UserInfo>(){
            new UserInfo(){Id=1,Name=jayjay1"},2,0)">jayjay2"}};
        }
    }

    [DataContract]
    class UserInfo
    {
        [DataMember]
        int Id { get; set; }

　　　　[DataMember]

　　　　string Name { set; } } }

注意别忘了给Service打上

[JavascriptCallbackBehavior(UrlParameterName = "jsoncallback")]

标记。

4.修改Web.config配置文件

<system.serviceModel> bindings> webHttpBinding> binding name="HttpJsonBinding" crossDomainScriptAccessEnabled="true"></binding</behaviors> endpointBehaviors> behavior ="AjaxServiceAspNetAjaxBehavior"> enableWebScript /> behaviorserviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled/> servicesservice ="AjaxService"endpoint address="" behaviorConfiguration="AjaxServiceAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration contract="AjaxService" /> service> >
