如何向 Response.Header 添加授权？

Question

我有以下控制器功能：

    [HttpGet("[action]")]
    public async Task<HttpResponseMessage> Login(string username, string password)
    {
        var user = await _userManager.FindByNameAsync(username);
        var res = await _signInManager.CheckPasswordSignInAsync(user, password, false);

        if (res.Succeeded)
        {
            var msg = new HttpResponseMessage(HttpStatusCode.OK);
            msg.Headers.Add("Authorization", JwtManager.GenerateToken(username));
            return msg;
        }
        else
            return new HttpResponseMessage(HttpStatusCode.BadRequest);// Request.CreateResponse(HttpStatusCode.BadRequest, new object());
    }

在 React 的 reducer 中我有这个：

let fetchTask = fetch('http://localhost:25565/api/mediaengine/login?username=' + userName + '&password=' + password)

            .then(response => {
                var k = response.headers.get("Authorization");
                var l = 0;
            })
            .catch(e => {
            });
        addTask(fetchTask);

由于某种原因 response.headers.get("Authorization") 返回 null..

您应该从 api 返回响应。这可以通过 HttpResponseMessage 类来完成

[HttpGet("[action]")]
public async Task<HttpResponseMessage> Login(string username, string password)
{
    var user = await _userManager.FindByNameAsync(username);
    var res = await _signInManager.CheckPasswordSignInAsync(user, password, false);

    if(res.Succeeded)
    {
        var response = Request.CreateResponse(HttpStatusCode.OK, new object());
        response.Headers.Add("Authorization", JwtManager.GenerateToken(username));
        return response;
    }else
        return Request.CreateResponse(HttpStatusCode.BadRequest, new object());
}
