对REST WebMethod的POST请求给出了404错误

Question

关于REST服务POST请求，下面是我编写的代码块，但它不起作用，404错误即将到来。

protected void Button1_Click(object sender, EventArgs e)
    {
        oRequest = (HttpWebRequest)WebRequest.Create("http://localhost:52811/FetchRecipe.svc/GetRecipe/5");
        oRequest.Method = "POST";
        oRequest.ContentType = "application/json";

        string strRequest = "{'iRecipeId':'5'}";
        oRequest.ContentLength = strRequest.Length;
        MemoryStream mo = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(strRequest));
        using (Stream sr = oRequest.GetRequestStream())
        {
            mo.CopyTo(sr);
            sr.Close();
        }

        oResponse = (HttpWebResponse)oRequest.GetResponse();
        Stream oResponseStream = oResponse.GetResponseStream();
        StreamReader sr1 = new StreamReader(oResponseStream);
        string sResponse = sr1.ReadToEnd();
    }

WCF合同接口

    [OperationContract]
    [WebInvoke(UriTemplate = "/GetRecipe")]
    List<RecipeModal> GetRecipe(string iRecipeId);

数据合同

[DataContract]
public class RecipeModal
{
    [DataMember]
    public int RecipeId { get; set; }

    [DataMember]
    public string RecipeTitle { get; set; }

    [DataMember]
    public int Servings { get; set; }

    [DataMember]
    public int ReadyTime { get; set; }

}

尝试将操作合同更改为以下内容，以便将url参数映射到函数参数：

 [OperationContract]
 [WebInvoke(UriTemplate = "GetRecipe/{iRecipeId}")]
 List<RecipeModal> GetRecipe(string iRecipeId);
