如何使用Swashbuckle将Swagger UI HTML作为字符串返回

services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new OpenApiInfo { Title = "Your API", Version = "v1" });
});

app.UseSwagger();
app.UseSwaggerUI(c =>
{
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "Your API V1");
});

[Route("api/[controller]")]
[ApiController]
public class SwaggerController : ControllerBase
{
    private readonly ISwaggerProvider _swaggerProvider;

    public SwaggerController(ISwaggerProvider swaggerProvider)
    {
        _swaggerProvider = swaggerProvider;
    }

    [HttpGet]
    public async Task<IActionResult> Get()
    {
        var swagger = await _swaggerProvider.GetSwaggerAsync(HttpContext.Request.PathBase);
        var swaggerJson = swagger.SerializeAsJsonString();

        return Content(swaggerJson, "application/json");
    }
}

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
    endpoints.MapControllerRoute(
        name: "swagger",
        pattern: "swagger",
        defaults: new { controller = "Swagger", action = "Get" });
});
