錯誤415而測試我WCF服務

Question

我有了這個OperationContract

[OperationContract] 
[WebInvoke(Method = "POST", 
    ResponseFormat = WebMessageFormat.Json, 
    BodyStyle = WebMessageBodyStyle.Wrapped, 
    UriTemplate = "json")] 
Response JSONData(Request request); 

並且以這種方式

<?xml version="1.0"?> 
<configuration> 

    <system.web>

    </system.web>

以這種方式形成的請求對象被配置RESTful服務

[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; } 
} 

我創建了一個小客戶端來測試這個查詢，我也用WCFTestClient和wor進行了測試很好。如果我嘗試通過提琴手訪問這個，雖然我得到一個415 Unsupported Media Type錯誤。

這個我試過以下方式

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" } } } 

我也嘗試部署該服務，看看是否提琴手將能夠訪問它的話，但事情了，因爲現在不是得到一個415我更加混亂得到400抱怨'Reference to an object not set to an instance of the object.'和我創建的小命令行客戶端會抱怨我的服務的位置There was no endpoint listening at。

我的問題是，我的配置文件有什麼問題，或者我用錯誤的方式編寫了提琴手請求？如果是，我該如何解決這個問題，以便我可以正常訪問我的服務？

我可以看到你正在使用BodyStyle = WebMessageBodyStyle.Wrapped

這意味着你需要與你的OperationContract預期變量的名稱來包裝的實際數據。總之這應該工作

{ "response": { "input": { "login_password": "pass", "login_username": "login name", "query": { "birthDate": "", "name": "robert" } } } } 

如果你想保持主體內容是那麼我建議你使用Bare代替Wrapped的車身風格。
