当Web应用程序托管在子目录中时,ASP.NET Core Swagger使用不正确的json url

Question

我按照这些说明向我的ASP.NET Core应用程序添加了swagger.

当我将它作为根网站托管时,它工作正常,但是当我将应用程序作为现有网站上的别名托管时,例如myserver.com/myapp,swagger会查找swagger.json错误的URL并报告:*无法读取来自的swagger JSON https://myserver.com/swagger/v1/swagger.json.它应该使用https://myserver.com/myapp/swagger/v1/swagger.json.

我收到的消息是:

无法从https://myserver.com/swagger/v1/swagger.json中读取swagger JSON

如何配置swashbuckle/swagger以使用应用程序基本路径并在正确的位置查找swagger.json文件？

我在IIS上托管.

swashbuckle的版本是:

"Swashbuckle": "6.0.0-beta902"

我怀疑我必须app.UseSwaggerUi()在Configure方法中添加一些内容,Startup.cs但我不确定是什么.

启动配置:

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
    }

    app.UseStaticFiles();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });

    // Enable middleware to serve generated Swagger as a JSON endpoint
    app.UseSwagger();

    // Enable middleware to serve swagger-ui assets (HTML, JS, CSS etc.)
    app.UseSwaggerUi();
}

您可以使用ASPNETCORE_APPL_PATH环境变量来获取应用程序基路径.

app.UseSwaggerUI(c =>
{
    string basePath = Environment.GetEnvironmentVariable("ASPNETCORE_APPL_PATH");
    if (basePath == null) basePath = "/";
    c.SwaggerEndpoint($"{basePath}swagger/v1/swagger.json", "My API");
});
