salesforce api 错误 ReasonPhrase: 'Bad Request'

Question

我访问这个https://test.salesforce.com/services/oauth2/authorizewerbservice 并在响应中获得一个代码。 现在使用此代码我想访问https://login.salesforce.com/services/oauth2/token

要访问这两种方法，我使用的是 c#.net。

当我尝试访问此https://login.salesforce.com/services/oauth2/token 时，我收到以下错误。

 "{\"error\":\"invalid_grant\",\"error_description\":\"authentication failure\"}"

我尝试了一整天，但我无法解决问题。 下面是我的代码。你可以检查一下，请告诉我那里有什么问题。 我的代码在这里。

            HttpClient authClient = new HttpClient();

            string sfdcConsumerKey = "3MVG9e2mBbsdfsdfsdfZnmgdbcsdfM6nG7.s.sffsdfsfbgfbvdfgdfgyeinHsdfsf";
            string sfdcConsumerSecret = "54324324324324";
            string sfdcUserName = "harish@gmail.com";
            string sfdcPassword = "mypassword123456";
            string sfdcToken = "fsdcbvcvbfgerwcxvx";
            string loginPassword = sfdcPassword + sfdcToken;
            string code = Request.QueryString["code"];
            HttpContent content = new FormUrlEncodedContent(new Dictionary<string, string>
            {
                {"grant_type","authorization_code"},
                {"code",code},
                {"client_id",sfdcConsumerKey},
                {"client_secret",sfdcConsumerSecret},
                {"username",sfdcUserName},
                {"password",loginPassword},
                {"redirect_uri","http://localhost:1474/Default.aspx"}                  
            }
            );


            HttpResponseMessage message = await authClient.PostAsync("https://login.salesforce.com/services/oauth2/token", content);

            string responseString = await message.Content.ReadAsStringAsync();

看看这个 git REPO for oauth provider for salesforce：

https://github.com/TerribleDev/OwinOAuthProviders/blob/master/src/Owin.Security.Providers.Salesforce/SalesforceAuthenticationHandler.cs

非常有用的包装器。
