关于AJAX调用WCF服务分为跨域和不跨域两种方式，今天咱们先介绍下不跨域下的调用方法。DEMO是在VS2008写的.
经过测试与研究，发现AJAX调用WCF服务必须满足以下条件
1.wcf的通讯方式必须使用webHttpBinding
2.必须设置
3.服务的实现必须添加标记
代码如下:[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
4.方法前面必须添加如下标记
代码如下:[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
5.ajax方法中传递的参数名称必须和wcf服务中提供的参数方法名称一致
以下是本人写的代码，标记颜色的是需要注意的地方
服务器端配置文件代码
服务器端代码
[ServiceContract]
public interface IService1
{
[OperationContract]
string GetData(int value);
[OperationContract]
City GetDataUsingDataContract(City composite);
[OperationContract]
List GetList();
[OperationContract]
List GetListData(List list);
}
// 使用下面示例中说明的数据约定将复合类型添加到服务操作。
[DataContract]
public class City
{
int seq = 0;
string cityID;
string ctiyName;
[DataMember]
public string CityID
{
get
{
return cityID;
}
set
{
cityID=value;
}
}
[DataMember]
public string CityName
{
get { return ctiyName; }
set { ctiyName = value; }
}
[DataMember]
public int Seq
{
get
{ return seq; }
set
{ seq = value; }
}
}
实现代码
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
#region IService1 成员
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
public City GetDataUsingDataContract(City composite)
{
City c = new City();
c.CityID = composite.CityID;
c.CityName = composite.CityName;
c.Seq = composite.Seq;
return c;
}
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
public List GetList()
{
List list = new List();
City cc = new City();
cc.CityID = "1";
cc.CityName="北京";
cc.Seq = 3;
list.Add(cc);
City cc1 = new City();
cc1.CityID = "2";
cc1.CityName = "上海";
cc1.Seq = 4;
list.Add(cc1);
return list;
}
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
public List GetListData(List list)
{
return list;
}
#endregion
}
