我正在尝试为API使用MVC和JWT的ASP.NET身份框架。要求是访问用户名/设备的API在URL中，例如API/V1/用户名/帐户。JWT是问题的用户或设备中都有用户名。我可以在startup.cs文件中进行吗？直到最近，下面的代码正常工作正常，它通过允许ASP.NET身份使用JWT受保护的API来开始做奇怪的事情。我想检查URL API/V1/用户名中的用户名是否匹配令牌一个。键是我的代码。感谢您的见解。

类似的东西可能会帮助您 -
app.UseWhen(context => context.Request.Path.Value.StartsWith("/api"), builder =>
{
...jwt code...
builder.MapWhen((ctx) =>
{
var userName = ctx.User.Claims.SingleOrDefault(c => c.Type == System.Security.Claims.ClaimTypes.Name)?.Value ?? "";
var testPath = new Microsoft.AspNetCore.Http.PathString($"/api/v2/computers/{userName}/");
var pathMatch = ctx.Request.Path.StartsWithSegments(testPath);
return String.IsNullOrWhiteSpace(userName) || !pathMatch;
}, cfg =>
{
cfg.Run((req) =>
{
req.Response.StatusCode = 403;
return req.Response.WriteAsync("");
});
});
});
当"名称"声明中的用户名（配置如何在此处获取用户名）中的用户名与给定的路径不匹配时，内部MapWhen将触发。然后，它将立即执行以下请求管道，该管道将返回带有空响应主体的403代码。
我不确定，如果您可以在同一请求管道中处理与身份相关的项目，实际上您添加身份。当用途之外，您可能必须提取代码时提取该地图。
