Configure PDF Web API Service

PDF Web API enables you to build HTTP services, which can be consumed by a variety of clients for viewing, loading and caching PDF files. These are REST based API services, which communicate with the HTML 5 PDFViewer control to display the pdf file content on the web.

Complete the following steps to setup PDF services.

Create a new WebAPI application

1. Open Visual Studio and Select Create a new project.
2. In the Create a new project window, select C1 from the Project Types drop down and select C1 Web API Application for ASP.NET Core (.Net Framework) and click Next.
3. Set a Name and Location for your application and click Create.
4. In the ComponentOne ASP.NET Web API Application Wizard, select Pdf services option.
   
   
5. Once you have selected the Services from the wizard, click OK to create a new C1 Web API Service application.

Configure Startup.cs file

1. Create a folder named PdfRoot, in your service application.

2. Add the desired PDF files to the PdfRoot folder.

3. From the Solution Explorer, select and open Startup.cs file.

4. In the Startup.cs file, replace the existing code under Startup class with the following code.

   public class Startup
       {
           public Startup(IWebHostEnvironment env, IConfiguration config, ILoggerFactory loggerFactory)
           {
               Environment = env;
               var builder = new ConfigurationBuilder()
                   .SetBasePath(env.ContentRootPath)
                   .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                   .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
                   .AddEnvironmentVariables();
               Configuration = builder.Build();
           }
           public static IWebHostEnvironment Environment { get; set; }
           public IConfiguration Configuration { get; }
           //Add services to the container.
           public void ConfigureServices(IServiceCollection services)
           {
               services.AddMvc();
               // Add framework services.
               //MESCIUS API
               services.AddMvc().ConfigureApplicationPartManager(manager =>
               {
                   var afp = manager.FeatureProviders.First(iafp => iafp.GetType() == typeof(ControllerFeatureProvider));
                   if (afp != null)
                   {
                       manager.FeatureProviders.Remove(afp);
                   }
                   manager.FeatureProviders.Add(new CustomControllerFeatureProvider());
               });
               // CORS support
               services.AddCors(options =>
                 {
                     options.AddPolicy("AllowAll", builder => builder.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());
                 });
               services.Configure<FormOptions>(options => options.ValueLengthLimit = int.MaxValue);
               // MESCIUS API
               services.AddMvc(option => { option.EnableEndpointRouting = false; });
               services.AddC1Api();
           }
           // Configure the HTTP request pipeline.
           public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
           {
               //MESCIUS API
               app.UseC1Api();
               app.UseStaticFiles();
               var defaultCulture = "en-US";
               IList<CultureInfo> supportedCultures = new List<CultureInfo>
               {
                   new CultureInfo(defaultCulture)
               };
               app.UseRequestLocalization(new RequestLocalizationOptions
               {
                   DefaultRequestCulture = new RequestCulture(defaultCulture),
                   SupportedCultures = supportedCultures,
                   SupportedUICultures = supportedCultures
               });
               app.UseMvc();
               //MESCIUS API
               app.UseStorageProviders()
                   .AddDiskStorage("PdfRoot", Path.Combine(env.WebRootPath, "Pdfs"));
           }
       }
   

   Notice that the disk storage is added in the Configure method of Startup using the AddDiskStorage method.
