Question

我已经创建了一个RESTful服务，它提供了以下响应：

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">hello</string>

但是，我希望它只返回'你好'。我怎么能这样做？

接口：

[ServiceContract]
public interface IApp
{
    [OperationContract]
    [WebInvoke(RequestFormat = WebMessageFormat.Xml,
        ResponseFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        Method = "GET",
        UriTemplate = "/ourapi/v1/admin/certificate")]
    string retrieveInfo();
}

C＃：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class App : IApp
{
    public string retrieveInfo()
    {
        WebOperationContext ctx = WebOperationContext.Current;

        var dateValue = DateTime.UtcNow.ToString("ddd, dd MMM yyyy HH:mm:ss UTC", CultureInfo.InvariantCulture);
        string merchantId = "1234567";
        string errorCodeValue = "00";

        ctx.OutgoingResponse.ContentType = "text/plain; charset=utf-8";
        ctx.OutgoingResponse.Headers.Add("date", dateValue);
        ctx.OutgoingResponse.Headers.Add("merchant-id", merchantId);
        ctx.OutgoingResponse.Headers.Add("error-code", errorCodeValue);

        return "hello";
    }
}

我一直这样做的方法是返回Stream。我还删除了您的请求和回复，并将BodyStyle设置为Bare。

[WebInvoke(BodyStyle = WebMessageBodyStyle.Bare,
    Method = "GET",
    UriTemplate = "/ourapi/v1/admin/certificate")]
Stream retrieveInfo();


[AspNetCompatibilityRequirements(RequirementsMode = 
     AspNetCompatibilityRequirementsMode.Allowed)]
public class App : IApp
{
    public Stream retrieveInfo()
    {
        WebOperationContext ctx = WebOperationContext.Current;

        var dateValue = DateTime.UtcNow.ToString("ddd, dd MMM yyyy HH:mm:ss UTC", CultureInfo.InvariantCulture);
        string merchantId = "1234567";
        string errorCodeValue = "00";

        ctx.OutgoingResponse.ContentType = "text/plain; charset=utf-8";
        ctx.OutgoingResponse.Headers.Add("date", dateValue);
        ctx.OutgoingResponse.Headers.Add("merchant-id", merchantId);
        ctx.OutgoingResponse.Headers.Add("error-code", errorCodeValue);

        return New System.IO.MemoryStream(Encoding.UTF8.GetBytes("hello"));
    }
}

您只需拥有两种XML和JSON的响应格式即可。但是你可以扩展WCF以产生你想要的东西。有关详细信息，请参阅article
