WCF BodyStyle WrappedRequest 不适用于传入的 JSON 参数? [英] WCF BodyStyle WrappedRequest doesn't work for incoming JSON param?

问题描述

我一直致力于让 RESTful WCF 服务既接受 JSON 作为参数又返回一些 JSON.

这是我的服务:

<块引用>

 [操作契约][网络调用(方法=POST"，BodyStyle = WebMessageBodyStyle.WrappedRequest,RequestFormat = WebMessageFormat.Json,ResponseFormat = WebMessageFormat.Json,UriTemplate = "验证")]公共 AuthResponse Authenticate(AuthRequest 数据){AuthResponse res = new AuthResponse();如果(数据！= null){Debug.WriteLine(data.TokenId);res.TokenId = new Guid(data.TokenId);}返回资源；}

当我通过 { AuthRequest: { TokenId = "some guid"} } 时，上面会设置 data 为空.

如果我将方法的 BodyStyle 设置为 Bare，则 data 设置正确，但我必须从 JSON 中删除 { AuthRequest } (我真的不想这样做).有没有办法让 WrappedRequests 与 { AuthRequest: { TokenId = "some guid"} 作为 JSON 一起使用?

谢谢.

解决方案

包装器的名字不是参数type，而是参数name.如果您将其作为 {"data":{"TokenId":"some guid"}} 发送，它应该可以工作.

或者如果你想使用参数名称以外的其他名称，你可以使用[MessageParameter]属性:

[操作契约][网络调用(方法=POST"，BodyStyle = WebMessageBodyStyle.WrappedRequest,RequestFormat = WebMessageFormat.Json,ResponseFormat = WebMessageFormat.Json,UriTemplate = "验证")]public AuthResponse Authenticate([MessageParameter(Name = "AuthRequest")] AuthRequest data)

I've been working on getting a RESTful WCF service to both accept a JSON as a parameter and return some JSON.

This is my service:

    [OperationContract]
    [WebInvoke(
        Method="POST",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        UriTemplate = "Authenticate")]
    public AuthResponse Authenticate(AuthRequest data)
    {
        AuthResponse res = new AuthResponse();
        if (data != null)
        {
            Debug.WriteLine(data.TokenId);
            res.TokenId = new Guid(data.TokenId);
        }
        return res;
    }

The above will set data to be null when I pass { AuthRequest: { TokenId = "some guid"} }.

If I set the BodyStyle of the method to be Bare then data is set correctly but I must remove { AuthRequest } from the JSON (which I don't really want to do). Is there any way to get WrappedRequests to work with { AuthRequest: { TokenId = "some guid"} as the JSON?

Thanks.

解决方案

The name of the wrapper is not the parameter type, but the parameter name. If you send it as {"data":{"TokenId":"some guid"}} it should work.

Or if you want to use some name other than the parameter name, you can use the [MessageParameter] attribute:

[OperationContract]
[WebInvoke(
    Method="POST",
    BodyStyle = WebMessageBodyStyle.WrappedRequest,
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json,
    UriTemplate = "Authenticate")]
public AuthResponse Authenticate([MessageParameter(Name = "AuthRequest")] AuthRequest data)
