IdentityServer4在nginx里设置跳转后，无法打开登录页的问题

现象描述：

id4的认证中心使用的是 http发布的，然后在nginx使用https来转发，结果出现，跳转到Account/Login路径，但是网页打不开。

nginx里配置如下：

server {
    listen       443 ssl;
    server_name  www.lzgjscc.cn;
    ssl_certificate ..\ssl\8380213_www.aaa.cn.pem;
    ssl_certificate_key ..\ssl\8380213_www.aaa.cn.key;
    ssl_session_timeout 30m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_prefer_server_ciphers on;
    ssl_ecdh_curve secp384r1;
    ssl_session_cache shared:SSL:50m;
    ssl_session_tickets off;
    ssl_stapling on; #ensure your cert is capable
    ssl_stapling_verify on; #ensure your cert is capable
    resolver 8.8.8.8 8.8.4.4 valid=300s;
    resolver_timeout 30s;
    #the next four lines of the configuration of nginx.conf is what made MVC Hybrid work correctly after publish:
    proxy_buffer_size   128k;
    proxy_buffers   4 256k;
    proxy_busy_buffers_size   256k;
    large_client_header_buffers 4 16k;
    location / {
    fastcgi_buffers 16 16k;
    fastcgi_buffer_size 32k;
    proxy_pass http://10.10.10.10:10010;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection keep-alive;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#must be set or wrong url
    proxy_set_header X-Forwarded-Proto $scheme;#must be set or wrong url
    proxy_cache_bypass $http_upgrade;
    proxy_set_header X-URL-SCHEME https;
    }
    }

解决方法：

　　1、在nginx里加上一行：

　　　　proxy_set_header X-Forwarded-Proto $scheme;

　　2、在startup.cs里加上如下代码：

public void Configure(IApplicationBuilder app)
        {
            if (Environment.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }
            var fordwardedHeaderOptions = new ForwardedHeadersOptions
            {
                ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
            };
            fordwardedHeaderOptions.KnownNetworks.Clear();
            fordwardedHeaderOptions.KnownProxies.Clear();
            app.UseForwardedHeaders(fordwardedHeaderOptions);
            app.UseCors("default");
            app.UseSession();
            app.UseCookiePolicy();
            app.UseStaticFiles();
            app.UseRouting();
            //app.UseHttpsRedirection();
            app.UseIdentityServer();
            app.UseAuthentication();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapDefaultControllerRoute();
            });
        }
