从 C# 客户端应用程序执行 Salesforce 身份验证时出错

Question

下面是我编写的与 login() 一起用于 Salesforce 身份验证的完整代码。但是，如果我在 .Net 客户端（控制台应用程序）中执行代码，则会出现错误。谁能建议我如何解决这个问题。

我的现场协调员已确认，只要涉及 Salesforce，一切都很好。

代码

        private bool login()
    {
        string username = "kak.mca@gmail.com";
        string password = "Temp0r@ry";
        string securityToken = "";
        string resultSessionId = string.Empty;
        string resultServerUrl = string.Empty;
        binding = new SforceService();
        binding.Timeout = 60000;
        LoginResult lr;
        try
        {
            #region Method1
            //lr = binding.login(username, password);
            #endregion Method1
            #region Method2
            using(binding)
            {
                lr = binding.login(username, password);
                resultSessionId = lr.sessionId;
                resultServerUrl = lr.serverUrl;
            }
            #endregion Method2
            return true;
        }
        catch (SoapException e)
        {
            Console.WriteLine("Fault code: " + e.Code + Environment.NewLine + "Error message: " + e.Message + Environment.NewLine + "Stack trace:" + e.StackTrace);
            return false;
        }
    }

错误:

<font color='red'>Fault code: INVALID_LOGIN<br />
Error message: INVALID_LOGIN: Invalid username, password, security token; or user Locked out.<br />

Answer 1

您缺少安全令牌。您可以通过导航至 您的姓名 > 设置 > 个人设置 > 我的个人信息 > 重置我的安全令牌来获得一个。您的密码变量应该是

password = loginPassword + securityToken;

Answer 2

错误是由于凭据不正确造成的。提交正确的凭据后，一切正常。
