Ovaj kratki vodič vodi kako spojiti PDF s C# REST API-jem. Naučit ćete spojiti sve PDF-ove s C# REST sučeljem pomoću SDK-a. Objasnit će sve korake potrebne za razvoj aplikacije za kombiniranje više PDF datoteka.
Preduvjet
preuzimanje datoteka Aspose.PDF Cloud SDK for Dotnet
Postavite C# projekt s gornjim SDK-om
Koraci za kombiniranje PDF-a s C# Low Code API-jem
- Postavite API ključ i SID za inicijalizaciju objekta klase PdfApi
- Stvorite objekt MergeDocuments i navedite popis PDF datoteka koje želite spojiti
- Učitajte sve izvorne PDF datoteke pomoću metode UploadFile() u klasi PdfApi
- Pozovite metodu PutMergeDocuments() za spajanje svih PDF datoteka u jednu odredišnu PDF datoteku
- Preuzmite i spremite izlaznu PDF datoteku koja sadrži sadržaj svih spojenih PDF datoteka
Ovi koraci sažimaju kako spojiti PDF online s C# REST API-jem. Upotrijebite objekt klase MergeDocuments za stvaranje popisa PDF datoteka koje želite spojiti i prenesite sve te PDF datoteke u oblak pomoću metode PdfApi.UploadFile() i pozovite metodu PutMergeDocuments() za spajanje PDF datoteka na mreži. API poziv vraća status OK nakon čega možete pozvati metodu DownloadFile za dohvaćanje izlazne PDF datoteke.

Ovaj kod nas je naučio kako spajati PDF datoteke s C# REST sučeljem. Koristite slične nazive u metodi UploadFile() kao što se koriste na popisu PDF datoteka u objektu MergeDocuments. Kada preuzmete rezultirajuću PDF datoteku, postavite parametar Position na nulu, inače nećete moći spremiti datoteku na disk.
Ovaj članak je objasnio kako spojiti PDF dokumente online s C# .NET-baziranim API-jem. Za izradu prazne PDF datoteke pogledajte sljedeći članak: Stvorite PDF dokument s NET REST API-jem.
