[英]Error 415 while testing my wcf service
我有一個具有此OperationContract
的Restful服務
[OperationContract]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "json")]
Response JSONData(Request request);
並以這種方式配置

以這種方式形成請求對象
[DataContract]
public class Query
{
[DataMember]
public string name { get; set; }
[DataMember]
public string birthDate { get; set; }
}
[DataContract]
public class Input
{
[DataMember]
public Query query { get; set; }
[DataMember]
public string login_username { get; set; }
[DataMember]
public string login_password { get; set; }
}
[DataContract]
public class Request
{
[DataMember]
public Input input { get; set; }
}
我創建了一個小型客戶端來測試此查詢,並且還使用WCFTestClient
對其進行了測試,並且工作正常。 如果我嘗試通過提琴手訪問此文件,但出現415 Unsupported Media Type
錯誤。
我以以下方式嘗試了
POST, http://localhost:8080/HostDevServer/SearchService.svc/json, HTTP/1.1
User-Agent: Fiddler
Content-Type: application/json;charset=UTF-8
Host: localhost:8080
Content-Length: 368
{ "input": { "login_password": "pass", "login_username": "login name", "query": { "birthDate": "", "name": "robert" } } }
我還嘗試部署了該服務,然后看提琴手是否能夠訪問它,但是事情變得更加令人困惑,因為現在不是得到415
而是得到了400
抱怨: 'Reference to an object not set to an instance of the object.'
並且我創建的小型命令行客戶端會抱怨There was no endpoint listening at
我的服務位置進行There was no endpoint listening at
。
我的問題是,我的配置文件有問題嗎,還是我以錯誤的方式編寫了提琴手請求? 如果是,如何解決此問題,以便可以正常訪問我的服務?
我可以看到您正在使用BodyStyle = WebMessageBodyStyle.Wrapped
這意味着您需要使用OperationContract
期望的變量名稱包裝實際數據。 簡而言之,這應該工作
{ "response": { "input": { "login_password": "pass", "login_username": "login name", "query": { "birthDate": "", "name": "robert" } } } }
如果您希望保持主體內容不變,那么建議您使用Bare
而不是Wrapped
作為主體樣式。
