C# 使用PostMan测试的C webapi身份验证令牌错误

我试图通过C用webapi创建一个登录身份验证令牌，并用PostMan进行了测试

这就是我所做的 C webapi

这是我的startup.cs

MyAuthProvider

WebApiConfig

我已经创建了数据库查询，如下所示：

use [DBSecurityTest]

CREATE TABLE [dbo].[UserLogin](  
    [Id] [int] IDENTITY(1,1) NOT NULL,  
    [UserName] [varchar](50) NULL,  
    [UserPassword] [varchar](50) NULL,  
    [UserEmail] [varchar](50) NULL,  
    [UserRole] [varchar](50) NULL,  
 CONSTRAINT [PK_UserLogin] PRIMARY KEY CLUSTERED   
(  
    [Id] ASC  
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]  
) ON [PRIMARY]  

GO  



-- insert data in table  
insert into UserLogin(UserName,UserPassword,UserEmail,UserRole)  
values ('admin','123456','admin@gmail.com','admin')  

-- create store procedure   
Create PROCEDURE [dbo].[EF_UserLogin]   
    @UserName varchar(50)=null,  
    @UserPassword varchar(50)=null  
AS  
BEGIN  

    SET NOCOUNT ON;  

    SELECT  UserName,UserPassword,UserEmail,UserRole from UserLogin where UserName=@UserName and UserPassword=@UserPassword  
END

我已经添加了我的ADO.Net模型

错误是我调试Api时无法通过Postman测试我的令牌

我的邮递员配置如下：

use [DBSecurityTest]

CREATE TABLE [dbo].[UserLogin](  
    [Id] [int] IDENTITY(1,1) NOT NULL,  
    [UserName] [varchar](50) NULL,  
    [UserPassword] [varchar](50) NULL,  
    [UserEmail] [varchar](50) NULL,  
    [UserRole] [varchar](50) NULL,  
 CONSTRAINT [PK_UserLogin] PRIMARY KEY CLUSTERED   
(  
    [Id] ASC  
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]  
) ON [PRIMARY]  

GO  



-- insert data in table  
insert into UserLogin(UserName,UserPassword,UserEmail,UserRole)  
values ('admin','123456','admin@gmail.com','admin')  

-- create store procedure   
Create PROCEDURE [dbo].[EF_UserLogin]   
    @UserName varchar(50)=null,  
    @UserPassword varchar(50)=null  
AS  
BEGIN  

    SET NOCOUNT ON;  

    SELECT  UserName,UserPassword,UserEmail,UserRole from UserLogin where UserName=@UserName and UserPassword=@UserPassword  
END

邮资/代币 我选择Body和x.www-form-urlencoded

错误随之而来 {错误：不支持的授予类型}

是我的邮递员配置错误还是我的C api代码有问题？

这是关于您的请求，当您使用邮递员发送请求时，您应该传递一个名为grant\u type的参数

OAuth框架为不同的用例指定了几种授权类型，以及创建新授权类型的框架

下面列出了最常见的OAuth授权类型

授权码 客户端凭据 设备代码 刷新令牌

欲了解更多信息，请阅读。

您是否为此编写了控制器？ 我认为你错过了一个控制器，因为它存储参数并处理它。您声明的方式似乎是在C WebApi后端没有处理

我想你可以参考这里的一些视频：

谢谢。

Hi@user13074015，我正在处理您的视频，它成功了！让我开始关注下面的API并完成代码。谢谢
