Azure Apps EasyAuth声称使用.NET Core

我想编写一些ASP .NET Core中间件来将Azure Apps EasyAuth HTTP标头转换为声明.我找到了两种方法：

>解析EasyAuth在HTTP标头中提供的令牌.这似乎不是一个通用的解决方案,因为我必须编写代码来解析每个身份提供者的令牌.
>向/.auth/me提出服务器端请求.这会返回一些我想要转换为声明的JSON,但我不确定是否必须手动执行此操作或者是否有框架支持.

#2是最好的方法,是否有任何框架支持？

解决方法

Startup.cs>配置

app.Use(async (context,next) =>
{
    // Create a user on current thread from provided header
    if (context.Request.Headers.ContainsKey("X-MS-CLIENT-PRINCIPAL-ID"))
    {
        // Read headers from Azure
        var azureAppServicePrincipalIdHeader = context.Request.Headers["X-MS-CLIENT-PRINCIPAL-ID"][0];
        var azureAppServicePrincipalNameHeader = context.Request.Headers["X-MS-CLIENT-PRINCIPAL-NAME"][0];

        #region extract claims via call /.auth/me
        //invoke /.auth/me
        var cookieContainer = new CookieContainer();
        HttpClientHandler handler = new HttpClientHandler()
        {
            CookieContainer = cookieContainer
        };
        string uriString = $"{context.Request.Scheme}://{context.Request.Host}";
        foreach (var c in context.Request.Cookies)
        {
            cookieContainer.Add(new Uri(uriString),new Cookie(c.Key,c.Value));
        }
        string jsonResult = string.Empty;
        using (HttpClient client = new HttpClient(handler))
        {
            var res = await client.GetAsync($"{uriString}/.auth/me");
            jsonResult = await res.Content.ReadAsStringAsync();
        }

        //parse json
        var obj = JArray.Parse(jsonResult);
        string user_id = obj[0]["user_id"].Value<string>(); //user_id

        // Create claims id
        List<Claim> claims = new List<Claim>();
        foreach (var claim in obj[0]["user_claims"])
        {
            claims.Add(new Claim(claim["typ"].ToString(),claim["val"].ToString()));
        }

        // Set user in current context as claims principal
        var identity = new GenericIdentity(azureAppServicePrincipalIdHeader);
        identity.AddClaims(claims); 
        #endregion

        // Set current thread user to identity
        context.User = new GenericPrincipal(identity,null);
    };

    await next.Invoke();
});
