我怎样才能从Web.Api控制器方法发送的cookie [英] How can I send a cookie from a Web.Api controller method

问题描述

我有一个接受的自定义类，并返回另一个自定义类的方法的Web.Api服务：

I have a Web.Api service which has a method that accepts a custom class and returns another custom class:

public class TestController : ApiController
{
    public CustomResponse Post([FromBody]CustomRequest request)
    {
        // process request
        ...
        // create response
        CustomResponse resp = new CustomResponse() { ... };
        return resp;
    }
}

现在我也想送一个cookie回作为HTTP响应的一部分。我该怎么做？

Now I want to also send a cookie back as part of the Http response. How can I do that?

推荐答案

我设法从几个不同的位置信息相结合做到这一点。首先，为了能够轻松地在响应发送的cookie中，Web.Api控制器应返回的实例 System.Net.Http.Htt presponseMessage 类（链接）：

I managed to do this by combining information from a few different locations. First, in order to easily be able to send cookies in the response, the Web.Api controller should return an instance of the System.Net.Http.HttpResponseMessage class (link):

public class TestController : ApiController
{
    public HttpResponseMessage Post([FromBody]CustomRequest request)
    {
        var resp = new HttpResponseMessage();
        ...

        //create and set cookie in response
        var cookie = new CookieHeaderValue("customCookie", "cookieVal");
        cookie.Expires = DateTimeOffset.Now.AddDays(1);
        cookie.Domain = Request.RequestUri.Host;
        cookie.Path = "/";
        resp.Headers.AddCookies(new CookieHeaderValue[] { cookie });

        return resp;
    }
}

但后来我如何确保我可以轻松地同时发送回 CustomResponse ？

诀窍是在回答本的问题。使用 Request.CreateResponse＆LT; T＆gt;该请求对象方法。然后，整个交易就变成了：

The trick is in the answer to this question. Use the Request.CreateResponse<T> method on the request object. The whole deal then becomes:

public class TestController : ApiController
{
    public HttpResponseMessage Post([FromBody]CustomRequest request)
    {
        // process request
        ...

        var resp = Request.CreateResponse<CustomResponse>(
            HttpStatusCode.OK,
            new CustomResponse() { ... }
        );

        //create and set cookie in response
        var cookie = new CookieHeaderValue("customCookie", "cookieVal");
        cookie.Expires = DateTimeOffset.Now.AddDays(1);
        cookie.Domain = Request.RequestUri.Host;
        cookie.Path = "/";
        resp.Headers.AddCookies(new CookieHeaderValue[] { cookie });

        return resp;
    }
}
