Question

我想实现正确的HTTP语义，并根据资源是否已创建或更新，以及在响应内容中描述创建的资源，从我的PUT操作返回200 OK或201 CREATED。

可悲的是，PUT的Web API示例没有向您展示如何执行此操作。您应该怎么做才能指定错误代码并返回响应正文？

Answer 1

如果您真的可以返回请求内容，那么这是一种更有效的方法。这将避免内容的所有反序列化和重新序列化。

public HttpResponseMessage Put(HttpRequestMessage request)
    {
        // do stuff

        return new HttpResponseMessage(created ? HttpStatusCode.Created : HttpStatusCode.OK ) {
            Content = request.Content
        };
    }

Answer 2

    // PUT 
    // path/to/{resourceName}
    public HttpResponseMessage Put(CreateResourceRequest request)
    {
        //do stuff...

        // Return 200 [OK] if it is an update and 201 [CREATED] if the resource is created. 
        // Usually, the response body should be same as the original request.
        var responseContent = request;
        return Request.CreateResponse(created ? HttpStatusCode.Created : HttpStatusCode.OK, responseContent);
    }

Web API - 如何在响应中返回特定的状态代码？
