Swagger support to Abp Elsa demo #1530

VivekKoppula created 4 years ago

I am trying to add swagger support by doing the following.

Added the following line of code the web module.

context.Services.AddElsaApiEndpoints();
// The following is throwing exception
context.Services.AddElsaSwagger();

But it is throwing exception. The exception is shown below for your reference. So I had to comment out.

Also tried to add the following code in the same ElsaDemoWebModule.cs file.

app.UseAbpSwaggerUI(options =>
{
options.SwaggerEndpoint("/swagger/v1/swagger.json", "ElsaDemo API");
// The following did not help.
options.SwaggerEndpoint("/swagger/v1/swagger.json", "Elsa");
});

But it did help. I get Elsa in the drop down, but selecting it does not give the elsa swagger UI.

The full exception is as follows.

An unhandled exception occurred while processing the request.
