Microsoft.Owin.Security.OAuth.OAuthAuthorizationServerProvider - 尝试从 Postman 生成令牌时 clientId 和 clientSecret 变为空

Question

我正在为我的 asp.net web api 2 应用程序使用 OWIN 安全性，这是我的启动 class 身份验证设置。

 public void ConfigureOAuth(IAppBuilder app)
    {

        var oAuthServerOptions = new OAuthAuthorizationServerOptions
        {
            AllowInsecureHttp = true,
            TokenEndpointPath = new PathString("/token"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
            Provider = new CustomAuthorizationServerProvider()
        };

        // Token Generation
        app.UseOAuthAuthorizationServer(oAuthServerOptions);
        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
    }

这里是 CustomAuthorizationServerProvider class 实现，

public class CustomAuthorizationServerProvider : OAuthAuthorizationServerProvider
{
    public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        context.TryGetFormCredentials(out var clientId, out var clientSecret);

        if (clientId == "987459827985" && clientSecret == "lkfjldsfjkld")
        {
            context.Validated(clientId);
        }

        return base.ValidateClientAuthentication(context);
    }

    public override Task GrantClientCredentials(OAuthGrantClientCredentialsContext context)
    {
        var oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
        oAuthIdentity.AddClaim(new Claim(ClaimTypes.Name, "TestClient"));
        var ticket = new AuthenticationTicket(oAuthIdentity, new AuthenticationProperties());
        context.Validated(ticket);
        return base.GrantClientCredentials(context);
    }
}

现在，在尝试使用端点 http://localhost:8080/token 生成令牌时，我得到的 clientId 和 clientSecret 都为 NULL，因此我得到 "error": "invalid_client"。我在这里缺少什么？

当我使用 raw 作为正文时，我可以看到令牌生成正在运行并且客户端和机密都具有价值。为什么它不适用于 form-data？

Answer 1

查看 postman 文档：Sending API requests

最重要的是：

Website forms often send data to APIs as multipart/form-data. You can replicate this in Postman using the form-data Body tab. Form data allows you to send key-value pairs, and specify the content type.

通过网络快速搜索，API 需要一种特殊类型的处理来绑定 multipart/form-data

即

There is even a plugin for that

内容类型很重要。
