Swagger UI show 404 error when I deploy it on IIS

Question

I have an asp.net core application with vue.js. I made web api. And when I'm debugging via localhost - everything is fine. Swagger UI is working, also as application. But when I deploy app to the IIS, Swagger don't work and show 404 error.

Here is swagger configuration in Startup.cs

services.AddSwaggerGen(config =>
        {
            var xmlFile = $"{System.Reflection.Assembly.GetExecutingAssembly().GetName().Name}.xml";
            var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
            config.IncludeXmlComments(xmlPath);
        });
app.UseSwagger(options =>
            {
                options.SerializeAsV2 = true;
                options.RouteTemplate = "info/swagger/{documentname}/swagger.json";
            });

            app.UseSwaggerUI(options =>
            {
                options.SwaggerEndpoint("/info/swagger/v1/swagger.json", "v1");
                options.RoutePrefix = "info/swagger";
            });

What should I do? changing SwaggerEnpoint to "../info/swager....." don't help. I need to working asp .net core app and also swagger on IIS.

Have you made sure that the documentation file is copied to your deployed files? — Daniel Kiptoon, Jan 22, 2022 at 17:37
@DanielKiptoon, yes, documentationfFile.xml in result directory. — Ilya Vasilevskiy, Jan 22, 2022 at 18:02

The problem was in

app.UseSwagger(options =>
            {
                options.SerializeAsV2 = true;
            });

app.UseSwaggerUI(options =>
        {
            options.SwaggerEndpoint("/applicationName/swagger/v1/swagger.json", "v1");
            options.RoutePrefix = "info/swagger";
        });

removing options.RouteTemplate and replace "info" on "appName" in options.SwaggerEndpoint helps me.

###options.RouteTemplate

Swagger路由添加前缀 .Net Web Api

.Net Core / .Net 6 项目更改Swagger 路由：

定义一个路由前缀或从配置里读取

var routePrefix = AppSettingsExt.Get("route_prefix");
xml文档按常规方式引入

builder.Services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Microsoft.OpenApi.Models.OpenApiInfo { Title = docTitle });
var files = new DirectoryInfo(AppContext.BaseDirectory).GetFiles("*.xml", SearchOption.AllDirectories);
foreach (var file in files)
{
c.IncludeXmlComments(file.FullName);
}
});
更改路由配置，UseSwagger 以及UseSwaggerUI 都需要修改

app.UseSwagger(c =>
{
c.RouteTemplate = routePrefix + "/swagger/{documentName}/swagger.json";
});
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint($"/{routePrefix}/swagger/v1/swagger.json", docTitle);
c.RoutePrefix = $"{routePrefix}/swagger";
});
