c# - 如何使用 HttpResponseMessage 返回客户数据

Question

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

现在我如何通过 HttpResponseMessage 类将我的客户对象传递到客户端？

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

假设如果我不想以这种方式返回响应Request.CreateResponse(HttpStatusCode.OK,customers);而是我想创建HttpResponseMessage的实例并初始化一些属性(property)，然后返还。那么告诉我我可以通过 HttpResponseMessage 类 将我的客户对象传递到客户端吗？

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，此方法将为您处理您不太关心的内容协商。否则，您必须手动处理，如下代码:

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;
