最近项目中需要编写一个服务,以供安卓和iOS调用.现在记录一下过程.(第一次写博客啊,潜水好久了......)
wcf 具体的东西就不多说啦.上步骤和代码....
首先新建一个wcf项目,新建一个实体类.代码如下
[DataContract] public class Users { [DataMember] public string Id { get; set; } [DataMember] public string Name { get; set; } [DataMember] public int Gender { get; set; } }然后在接口中编写一些get和post方法.
[OperationContract] [WebGet(UriTemplate = "GetUsers", ResponseFormat = WebMessageFormat.Json)] [System.ComponentModel.Description("获取全部用户")] ICollection<Users> GetUsers(); [OperationContract] [WebGet(UriTemplate = "GetUserById/{id}", ResponseFormat = WebMessageFormat.Json)] [System.ComponentModel.Description("根据id获取用户")] Users GetUserById(string id); [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "AddUser", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)] [System.ComponentModel.Description("添加用户")] Users AddUser(Users news);实现接口方法,代码如下:
private ICollection<Users> _listCollection = new List<Users>() { new Users() { Id = "1",Gender=1,Name="张无忌" }, new Users() { Id = "2",Gender=2,Name="张三丰" }, new Users() { Id = "3",Gender=1,Name="任盈盈" }, }; public ICollection<Users> GetUsers() { return _listCollection; } public Users GetUserById(string id) { return _listCollection.FirstOrDefault(v => v.Id == id); } public Users AddUser(Users news) { _listCollection.Add(news); return news; }最后在配置文件中加入如下代码:
<system.serviceModel> <bindings> <webHttpBinding> <binding name="webBinding" closeTimeout="00:40:00" receiveTimeout="00:40:00" sendTimeout="00:40:00"maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" useDefaultWebProxy="false" > <security mode="None"></security> <readerQuotas maxDepth="32" maxArrayLength="2147483647" maxStringContentLength="2147483647" maxBytesPerRead="2147483647"/> </binding> </webHttpBinding> </bindings> <services> <service name="WcfServiceTest.Service1" behaviorConfiguration="wgjServiceBehavior"> <endpoint address="" behaviorConfiguration="webBehavior" binding="webHttpBinding" bindingConfiguration="webBinding" contract="WcfServiceTest.IService1"> </endpoint> </service> </services> <behaviors> <endpointBehaviors> <behavior name="webBehavior"> <!--这里必须设置--> <webHttp helpEnabled="true"/> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="wgjServiceBehavior"> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>
加上helpEnabled="true"并且在接口上加上System.ComponentModel.Description可在接口地址后面加上/help浏览方法说明.效果如下图
最后我们新建一个控制台应用程序来测试接口.
在项目中添加NuGet程序包中添加Http Client库:如图
现在开始编写方法:
private static async void GetUserById(string id) { Console.WriteLine("-----------根据id获取用户----------"); HttpClient httpClient = new HttpClient(); var result = await httpClient.GetStringAsync("http://localhost:31572/Service1.svc/getUserById/1"); Console.WriteLine(result); } private static async void GetUsers() { Console.WriteLine("-----------获取所有用户----------"); HttpClient httpClient = new HttpClient(); var result = await httpClient.GetStringAsync("http://localhost:31572/Service1.svc/GetUsers"); Console.WriteLine(result); } public static async void AddUser() { Console.WriteLine("------------添加用户-----------------"); HttpClient httpClient = new HttpClient(); var jobj = new JObject(); jobj["Id"] = "4"; jobj["Name"] = "大师兄"; jobj["Gender"] = 1; string str = jobj.ToString(); HttpContent content = new StringContent(str); content.Headers.ContentType = new MediaTypeHeaderValue("application/json"); var response = await httpClient.PostAsync("http://localhost:31572/Service1.svc/AddUser", content); response.EnsureSuccessStatusCode();//错误引发异常 Console.WriteLine(response.Content.ReadAsStringAsync().Result); }最后,这次就写到这里.下次是使用wcf rest 上传文件....
