如何使用HttpResponseMessage返回客户数据

Question

    HttpResponseMessage r = new HttpResponseMessage();
    r.StatusCode = HttpStatusCode.OK;
    r.ReasonPhrase = "SUCCESS";

现在如何将我的客户对象按HttpResponseMessage类传递给客户端？

一种方法是 return Request.CreateResponse(HttpStatusCode.OK, customers);

假设我不想以这种方式返回响应，Request.CreateResponse(HttpStatusCode.OK, customers);而是想创建的实例HttpResponseMessage并初始化一些属性，然后返回。所以告诉我，我可以将我的客户对象传递HttpResponseMessage class给客户端吗？

简单的方法是您应该根据请求创建响应：

return Request.CreateResponse(HttpStatusCode.OK, customers);

因为在幕后，这种方法将为您处理内容协商，而您并不在乎。否则，您必须手动处理以下代码：

IContentNegotiator negotiator = this.Configuration.Services.GetContentNegotiator();

ContentNegotiationResult result = negotiator.Negotiate(
    typeof(Customer), this.Request, this.Configuration.Formatters);

var response = new HttpResponseMessage
{
    StatusCode = HttpStatusCode.OK,
    Content = new ObjectContent<Customer>(customer,
        result.Formatter, result.MediaType)
};

return response;
