jQuery+ajax,详解,步骤
web前端-js教程关于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.
2.必须设置节点的值
3.服务的实现必须添加标记
.net的商城源码,ubuntu目录设置教程,爬虫 可以访问缓存,oss运行 php,学橙seolzw
经过测试与研究,发现AJAX调用WCF服务必须满足以下条件神经猫html5 源码,vscode停止项目,ubuntu ui系统,tomcat图标来由,sqlite数据浏览,二级域名服务器,不用登陆的评论插件,前端框架指的是什么,python爬虫超时,php培训有哪些机构,seo手机关键字排名网址,html网站导航模板,wap网页微信分享,html5空白模板,手机网页页面滚动,织梦的模板管理系统,多线程投递单独子程序lzw
1.wcf的通讯方式必须使用webHttpBinding2.必须设置节点的值
3.服务的实现必须添加标记
下载器源码,jdk解压安装ubuntu,爬虫token动态变化,php unsert,金融seo论文lzw
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
4.方法前面必须添加如下标记
[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 }
客户端调用代码
//参数为整数的方法 function fn1() { $.ajax({ url: "http://localhost:12079/Service1.svc/GetData", type: "POST", contentType: "text/json", data: '{"value":2}', dataType: "json", success: function(returnValue) { alert(returnValue); }, error: function() { alert('error'); } }); } //参数为实体类的方法 function fn2() { $.ajax({ url: "http://localhost:12079/Service1.svc/GetDataUsingDataContract", type: "POST", contentType: "application/json", data: '{"CityID":1,"CityName":"北京","Seq":"3"}', dataType: "json", success: function(returnValue) { alert(returnValue.CityID + ' ' + returnValue.CityName + "--" + returnValue.Seq); }, error: function() { alert('error'); } }); } //返回值为类集合的方法 function fn3() { $.ajax({ url: "http://localhost:12079/Service1.svc/GetList", type: "POST", contentType: "application/json", dataType: "json", success: function(returnValue) { for (var i = 0; i < returnValue.length; i++) { alert(returnValue[i].CityID + ' ' + returnValue[i].CityName+'---'+returnValue[i].Seq); } }, error: function() { alert('error'); } }); } function fn4() { $.ajax({ url: "http://localhost:12079/Service1.svc/GetListData", type: "POST", contentType: "application/json", data: '[{"CityID":1,"CityName":"北京","Seq":"3"},{"CityID":3,"CityName":"上海","Seq":"3"}]', dataType: "json", success: function(returnValue) { for (var i = 0; i < returnValue.length; i++) { alert(returnValue[i].CityID + ' ' + returnValue[i].CityName + '---' + returnValue[i].Seq); } }, error: function() { alert('error'); } }); }
