使用netcore 3.1 + nginx +Swashbuckle.AspNetCore 5.6.3 部署

出現如下錯誤

部署在windows下 專案正常，直接用VS除錯執行也正常顯示，釋出在Linux下無法訪問，Linux下使用的是nginx代理，所以推測是nginx代理問題，

經過兩天查閱和嘗試，最終確認問題為

 app.UseSwagger(c=> 
            {
                c.PreSerializeFilters.Add((doc, item) 
 
=>
                {
                    //根據代理伺服器提供的協議、地址和路由，生成api文件服務地址
                    doc.Servers = new List<OpenApiServer> 
                    { 
                        new OpenApiServer 
                        { 
                            Url = $"{item.Scheme}://{item.Host.Value}/{item.Headers["X-Forwarded-Prefix"]}"
 
    
                        } 
                    };
                });
            });

            app.UseSwaggerUI(c =>
            {
                c.ShowExtensions();
                c.ValidatorUrl(null);

                c.SwaggerEndpoint("/swagger/v1/swagger.json", $"{ApiName} V1");

              
                c.RoutePrefix 
 
= string.Empty;

                c.DocExpansion(DocExpansion.None);
            });

nginx配置

location / {
                proxy_pass http://localhost:5000;
                #proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection keep-alive;

                proxy_set_header   X-Forwarded-Prefix swagger;     #------其中swagger可以更換任何路由
                proxy_set_header X-Real-IP $remote_addr;
