Question

有两个asp.net mvc项目。一个是mvc api，另一个是mvc web。使用owin for auth2的mvc api。和mvc web访问api支持，而不是js。问题是，当web（支持）访问api时，将没有响应，但如果我使用桌面win form客户端，它可以工作。我想知道为什么，以及如何解决它。

一些代码和包，vs2015

owin客户端

private HttpClient _client;
....
    private async Task<TokenParam> GetAccessToken(string user,string psw)
    {
        var parameters = new Dictionary<string,string>();
        parameters.Add("grant_type","password");
        parameters.Add("username",user);
        parameters.Add("password",psw);

        _client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(Id + ":" + Secret)));

        var response = await _client.PostAsync("/token",new FormUrlEncodedContent(parameters));
        var value = await response.Content.ReadAsStringAsync();-----> here no response back from api server

        if (response.StatusCode == HttpStatusCode.OK)
        {
            var o = value.FromJson<TokenParam>();
            o.LoginTime = DateTime.Now.AddSeconds(-10);
            return o;
        }
        return null;
    }

owin服务器端

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
        oAuthIdentity.AddClaim(new Claim(ClaimTypes.Name,context.UserName));
        var ticket = new AuthenticationTicket(oAuthIdentity,new AuthenticationProperties());
        context.Validated(ticket);
        await base.GrantResourceOwnerCredentials(context);
    }
