I get a 404 for a JavaScript file that I am trying to inject in my swagger. Following is my swagger config
var thisAssembly = typeof(SwaggerConfig).Assembly;
GlobalConfiguration.Configuration
.EnableSwagger(c =>
{
c.SingleApiVersion("v1", "A title for your API");
})
.EnableSwaggerUi(c =>
{
c.InjectJavaScript(thisAssembly,"MyApi.Api.SwaggerExtensions.inject.js");
});
For inject.js build action is set to embedded resource and logical path is correct as my project name is MyApi.Api and the file is in a folder within the project named SwaggerExtensions
When using custom resources the resource name should contain the default namespace of your project as described here. In your case the configuration should be:
c.InjectJavaScript(thisAssembly, "AcctMgmt.SwaggerExtensions.inject.js")
I spent a lot of time trying to figure out that a method with the same name has a different behavior. The config in Startup.Configure expects a relative path from wwwroot:
public void Configure(IApplicationBuilder app) {
//
app.UseSwagger();
app.UseSwaggerUI(c => {
c.SwaggerEndpoint("/swagger/v1/swagger.json", "Salon API v1");
c.InjectJavascript("/SwaggerExtension.js");
});
}
Get started with Swashbuckle and ASP.NET Core

In my localhost, my swagger UI working well. localhost:3030/documentation
This UI was working on the server also but from today on the server it is not working https://digitalpathshalabd.com/documentation
Errors
I faced the same "SwaggerUIBundle is not defined" with a blank page. Also the problem only on server and not local. And it also had worked in the past.
Then when I ctrl+f5 the local swagger page, it then also appeared local.
For us it appeared the Configuration order was swapped.
For me the fix was moving app.UseRouting() after the swagger init
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
{
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "Procedure Service V1");
c.RoutePrefix = "";
});
app.UseRouting();
I am using org.springdoc:springdoc-openapi-ui:1.6.9 version and was facing this problem.
I checked https://www.npmjs.com/package/swagger-ui and added maven dependency for a lower swagger-ui version 3.0.21
<dependency>
<groupId>org.webjars</groupId>
<artifactId>swagger-ui</artifactId>
<version>3.0.21</version>
</dependency>
I found that the "swagger-ui/index.html" does not reference "swagger-initializer.js" , instead its source code is present in index.html itself (this the boiler-plate referring to pet store)
So in my Spring boot classpath resources/public folder, I copied the older swagger dist index.html file (which has the initializer code) and did the following changes
Changed the url part to point to my api-docs url. (e.g. /v3/api-docs)
Added "swagger-ui" to the src references, so that the swagger bundles/js will be called successfully from my index.html
<script charset="UTF-8" src="./swagger-ui/swagger-ui-bundle.js"></script>
<script charset="UTF-8" src="./swagger-ui/swagger-ui-standalone-preset.js"> </script>
When I accessed index.html - http://{server}:{port}/index.html- I could access my local Open API doc.
Check your swagger middleware configured correctly?
public void ConfigureServices(IServiceCollection services)
{
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
});
services.AddControllers();
}
This adds the Swagger generator to the services collection.
In the Configure() method, let’s enable the middleware for serving the generated JSON document and the Swagger UI:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseSwagger();
// Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.),
// specifying the Swagger JSON endpoint.
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
});
}
I downloaded a new .Net Core MVC project template from https://aspnetboilerplate.com/Templates, setup everything (database and restored nuget packages) and ran the Host application. All good as I get the Swagger UI going and can see all the standard services.
I then proceeded to create a simple API controller in the Host application:
[Route("api/[controller]")]
[ApiController]
public class FooBarController : MyAppControllerBase
{
public string HelloWorld()
{
return"Hello, World!";
}
}
And then Swagger fails to load the API definition:
Fetch error
Internal Server Error http://localhost:21021/swagger/v1/swagger.json
If I remove the Route and ApiController attributes, Swagger works again, but my new controller is not displayed. I can access it by going to http://localhost:21021/foobar/helloworld which is probably fine, but I'd like it to show up in Swagger UI.
Am I missing something?
This is how you should configure your Swagger in your "Configure(IApplicationBuilder app, IHostingEnvironment env)" method.
#region Swagger COnfiguration
app.UseSwagger();
// Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.),
// specifying the Swagger JSON endpoint.
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("swagger/v1/swagger.json", "Your class name");
c.RoutePrefix = string.Empty;
});
#endregion
And here will be your configureServices settings for swagger.
services.AddSwaggerGen(config =>
{
config.SwaggerDoc("v1", new Info
{
Title = "Title Here",
Version = "v1"
});
});
I have a basic asp.net core 2.1 web API. I installed NSwag.ASPNetCore nuget package.
here is my startup.cs. When I run this on IIS Express, swagger is working fine.
Once I deploy this to IIS, I am getting 404 not found.
Do I need to add a Path somewhere?
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(o => o.AddPolicy("CorsPolicy", builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader();
}));
services.AddMvc();
// Add framework services.
services.AddMvc()
.AddJsonOptions(options =>
{
options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
options.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore;
}).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
//Add Application Services
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddSwaggerDocument();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseCors("CorsPolicy");
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseSwagger();
app.UseSwaggerUi3();
app.UseMvc();
}
}
As mentioned by Rico below: upgrading to nswag v13 should fix the issue (for me it worked).
For versions of nswag before v13:
I had the same problem and I found a solution here: NSwag Issue #1914
What you need to do is configure a 'transform to external path':
app.UseSwaggerUi3(config =>
{
config.TransformToExternalPath = (s, r) =>
{
string path = s.EndsWith("swagger.json") && !string.IsNullOrEmpty(r.PathBase)
? $"{r.PathBase}{s}"
: s;
return path;
};
});
This worked for me on my iisexpress and on iis.
Check if you do not use Virtual Path for the application. Swagger by default checks absolute path instead of
localhost:port/MyVirtualPath/swagger/v1/swagger.json
It may happen when you use IIS server with virtual path delimiter.
I am having difficulty using a custom index.html and other assets with swashbuckle. Swashbuckle/Swagger do not seem to recognizing or using them at all. I do have app.UseDefaultFiles() and app.UseStaticFiles() set. I am trying to understand what I am doing incorrectly.
I have attempted to set up my configuration somewhat similar to what is defined on the Microsoft article without success. (https://learn.microsoft.com/en-us/aspnet/core/tutorials/web-api-help-pages-using-swagger?tabs=visual-studio)
I am presently using the files from the dist folder referenced in the article (https://github.com/swagger-api/swagger-ui/tree/2.x/dist) along with the custom css file provided.
My index.html file is located under /wwwroot/swagger/ui
The custom css file is located under /wwwroot/swagger/ui/css (as custom.css)
Here is my Startup.cs class.
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc()
.AddJsonOptions(options =>
{
// Swagger - Format JSON
options.SerializerSettings.Formatting = Formatting.Indented;
});
// Register the Swagger generator, defining one or more Swagger documents
services.AddSwaggerGen(c =>
{
c.DescribeAllEnumsAsStrings();
c.DescribeStringEnumsInCamelCase();
// c.DescribeAllParametersInCamelCase();
c.SwaggerDoc("v1",
new Info
{
Title = "My Web API - v1",
Version = "v1",
Description = "New and improved version. A simple example ASP.NET Core Web API. "
}
);
c.SwaggerDoc("v2",
new Info
{
Title = "My Web API - v2",
Version = "v2",
Description = "New and improved version. A simple example ASP.NET Core Web API. "
}
);
// Set the comments path for the Swagger JSON and UI.
var basePath = AppContext.BaseDirectory;
var xmlPath = Path.Combine(basePath, "ApiTest.xml");
c.IncludeXmlComments(xmlPath);
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
string swaggerUIFilesPath = env.WebRootPath + "\\swagger\\ui";
if (!string.IsNullOrEmpty(swaggerUIFilesPath))
{
app.UseDefaultFiles();
app.UseStaticFiles(new StaticFileOptions
{
FileProvider = new PhysicalFileProvider(swaggerUIFilesPath),
RequestPath = new PathString("/api-docs"),
});
}
// Enable middleware to serve generated Swagger as a JSON endpoint.
app.UseSwagger(c =>
{
c.RouteTemplate = "api-docs/{documentName}/swagger.json";
});
// Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.), specifying the Swagger JSON endpoint.
app.UseSwaggerUI(c =>
{
//c.ShowJsonEditor();
c.RoutePrefix = "api-docs";
c.SwaggerEndpoint("/api-docs/v1/swagger.json", "My Web API - V1 ");
c.SwaggerEndpoint("/api-docs/v2/swagger.json", "My Web API - V2 ");
c.DocumentTitle("My Web API");
});
app.UseMvc();
}
}
My ultimate objective is to be able to use something like the slate style theme available here (https://github.com/omnifone/slate-swagger-ui). For right now, I am just trying to get Swashbuckle/Swagger to use the customized files referenced in the Microsoft documentation before trying to make the other files work.
I really do NOT want to try and convert my assets to embedded resources--since there will many of them. I just want to reference a normal index.html file and be able to use all of its referenced files.
What am I doing wrong?
Relevant Software Versions
.Net Core Version: 2.0.3
Swashbuckle.AspNetCore: 1.2.0
Windows 10 Enterprise Build 1703
Visual Studio 2017 Enterprise 15.5.2
Here is the minimum action I found to be necessary to replace SwashBuckle's index.html in a .NET Core project:
Get a copy of the original index.html from here: https://github.com/domaindrivendev/Swashbuckle.AspNetCore/blob/master/src/Swashbuckle.AspNetCore.SwaggerUI/index.html
Place that copy in some sub-folder of your project.
The file may have a different name, I chose:
\Resources\Swagger_Custom_index.html
Right-click that file in Solution Explorer, select 'Properties', select 'Configuration Properties' in left pane. Under 'Advanced' in right pane find entry 'Build Action' and set it to 'Embedded resource'. Click Ok.
In Startup.cs add the following line to your app.UseSwaggerUI() call:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
//...
app.UseSwaggerUI(c =>
{
c.IndexStream = () => GetType().GetTypeInfo().Assembly.GetManifestResourceStream("Your.Default.Namespace.Resources.Swagger_Custom_index.html");
});
//...
}
The identifier for the file resource in the above GetManifestResourceStream method is composed of:
your default namespace (i.e. 'Your.Default.Namespace')
the sub-path of your resource (i.e. 'Resources')
the filename of your resource (i.e. 'Swagger_Custom_index.html')
All three parts are concatenated using dots (NO slashes or backslashes here).
If you don't use a sub-path but have your resource in root, just omit part 2.
For people who separate ApplicationBuilder config methods on ASP.NET Core:
If the separated method/class is static, it is not possible to call GetType() because an object reference is required.
In that case, switch GetType() to MethodBase.GetCurrentMethod().DeclaringType
c.IndexStream = () => MethodBase.GetCurrentMethod().DeclaringType.Assembly.GetManifestResourceStream("xxx.index.html");
I'm using swagger but when I host my webapi in IIS, swagger is stripping the website name off. The website is a virtual directory/application in IIS called LotsWebApi.
When I hit this url: http://localhost/LotsWebApi/swagger/ui/index.html
I get "Can't read swagger JSON from http://localhost/swagger/v1/swagger.json"
You can see that it is stripping off the 'LotsWebApi'.
My register swagger code looks like this...
private static void RegisterSwagger(IServiceCollection services)
{
services.AddSwaggerGen();
services.ConfigureSwaggerGen(options =>
{
options.SingleApiVersion(new Info
{
Version = "v1",
Title = "LOTS Web API",
Description = "API for LOTS Web"
});
});
services.AddSwaggerGen();
}
