C# WCF REST 服务响应 - 删除自动生成的内容

Question

我创建了一个 RESTful 服务，它提供以下响应：

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

但是，我只希望它 return 'hello'。我该怎么做？

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";
    }
}

Answer 1

我一贯的做法是return一个Stream。我还删除了您的请求和响应，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"));
    }
}

简单地说，你可以有两种类型的响应格式XML和JSON。但是你可以扩展 WCF 来产生你想要的。有关详细信息，请参阅 article
