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....
