C# Owin OAuth上下文：前端登录发送Json

我有一个Web API项目，使用OAuth/Owin处理身份验证

当我通过表单发布时，一切都很好。但是前端团队将发布application/json，我无法更改我的方法来接收这个json

当我想要接收Json时，我通常使用[FromBody]，但这次不行

我的代码：

    public override async Task ValidateClientAuthentication([FromBody]OAuthValidateClientAuthenticationContext context)
    {
        context.Validated();
    }

    public override async Task GrantResourceOwnerCredentials([FromBody]OAuthGrantResourceOwnerCredentialsContext context)
    {
        try
        {
            ....
        }
        catch (Exception e)
        {
            context.SetError("invalid_grant", "User not found");
        }
    }
}

        public static void ConfigureOAuth(IAppBuilder app, IContainer container)
    {
        OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true, // HTTPS == false
            TokenEndpointPath = new PathString("/security/login"),
            AccessTokenExpireTimeSpan = TimeSpan.FromHours(2),
            Provider = container.Resolve<IOAuthAuthorizationServerProvider>()                
        };

        app.UseOAuthAuthorizationServer(OAuthServerOptions);
        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
    }

我的OAuth配置：

    public override async Task ValidateClientAuthentication([FromBody]OAuthValidateClientAuthenticationContext context)
    {
        context.Validated();
    }

    public override async Task GrantResourceOwnerCredentials([FromBody]OAuthGrantResourceOwnerCredentialsContext context)
    {
        try
        {
            ....
        }
        catch (Exception e)
        {
            context.SetError("invalid_grant", "User not found");
        }
    }
}

        public static void ConfigureOAuth(IAppBuilder app, IContainer container)
    {
        OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true, // HTTPS == false
            TokenEndpointPath = new PathString("/security/login"),
            AccessTokenExpireTimeSpan = TimeSpan.FromHours(2),
            Provider = container.Resolve<IOAuthAuthorizationServerProvider>()                
        };

        app.UseOAuthAuthorizationServer(OAuthServerOptions);
        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
    }

publicstaticvoid配置OAuth（IAppBuilder应用程序，IContainer容器）
{
OAuthAuthorizationServerOptions OAuthServerOptions=新的OAuthAuthorizationServerOptions（）
{
AllowInsecureHttp=true，//HTTPS==false
TokenEndpointPath=新路径字符串（“/security/login”），
AccessTokenExpireTimeSpan=TimeSpan.FromHours（2），
Provider=container.Resolve（）
};
使用OAuthAuthorizationServer（OAuthServerOptions）；
使用OAuthBeareAuthentication（新的OAuthBeareAuthenticationOptions（））；
}

Json示例：

    public override async Task ValidateClientAuthentication([FromBody]OAuthValidateClientAuthenticationContext context)
    {
        context.Validated();
    }

    public override async Task GrantResourceOwnerCredentials([FromBody]OAuthGrantResourceOwnerCredentialsContext context)
    {
        try
        {
            ....
        }
        catch (Exception e)
        {
            context.SetError("invalid_grant", "User not found");
        }
    }
}

        public static void ConfigureOAuth(IAppBuilder app, IContainer container)
    {
        OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true, // HTTPS == false
            TokenEndpointPath = new PathString("/security/login"),
            AccessTokenExpireTimeSpan = TimeSpan.FromHours(2),
            Provider = container.Resolve<IOAuthAuthorizationServerProvider>()                
        };

        app.UseOAuthAuthorizationServer(OAuthServerOptions);
        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
    }

{grant_type:“password”，username:“myuser”，password:“mypass”}

在请求正文中阅读

context.Request.Body.Position = 0; // this resets the read position to 0
var payload = await new StreamReader(context.Request.Body).ReadToEndAsync();

从这里可以得到JSON对象的字符串。您可以使用反序列化程序将其转换为CLR类型。

您可以读取json表单请求。dynamic obj=wait Request.Content.ReadAsAsync（）；
