一、方法默认只有一个参数
(1)BodyStyle = WebMessageBodyStyle.Bare
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
[Description("地址解析(多个地址以','间隔,解析结果以JSON格式返回)")]
string Parse(string address);
------------------------------------------------------------------------------------
c#代码在客户端调用时,使用以下语句:
//SufeiHttpHelper是一个第三方的http请求调用工具
SufeiHttpHelper helper = new SufeiHttpHelper();
var item = new HttpItem();
item.URL = "http://localhost:35401/parse";
item.ContentType = "application/json";
item.Method = "post";
item.PostEncoding = Encoding.GetEncoding("utf-8");
item.Postdata = ""天津大学"";
(2)BodyStyle = WebMessageBodyStyle.Wrapped
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
[Description("地址解析(多个地址以','间隔,解析结果以JSON格式返回)")]
string Parse(string address);
---------------------------------------------------------------------------------------
item.PostEncoding = Encoding.GetEncoding("utf-8");
item.Postdata = "{"address":"天津"}"; //包装成json格式,并且指定参数名称
总结:以上两个形式,在传入string参数为中文时,必须要包装成json,如果是数字或字母,在BodyStyle = WebMessageBodyStyle.Bare),可以直接传入,无需包装成json
二、方法有多个参数
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped)]
Stream HelloDataStr(String data1,string data2);
由于是多个参数,BodyStyle必须为 WebMessageBodyStyle.Wrapped,否则参数无法映射。
客户端调用:
item.PostEncoding = Encoding.GetEncoding("utf-8");
item.Postdata = {"data1":"hh","data2":"ss"}");
三、使用rest风格的url
[OperationContract]
[WebInvoke(Method="POST",ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare,UriTemplate ="Delete/{keyword}")]
[Description("删除无效IP")]
string DeleteKeyword(string keyword);
客户端调用:
var url = "http://localhost:24320/delete/中国";
item.Method = "post";
//无需再使用item.postdata语句
