Riordinare le pagine di un PDF
Riorganizzare le pagine di un PDF nell’ordine esatto che si indica: una ripetizione duplica una pagina, un’omissione la scarta.
Riorganizzare le pagine di un PDF in qualsiasi ordine tramite il parametro
page_order. Poiché page_order usa la sintassi
ordinata delle pagine, questa azione funge anche da
estrazione e riordino combinati: le pagine omesse vengono scartate e una pagina
indicata due volte viene ripetuta. L’API è stateless: il documento viene
elaborato nella regione e non viene mai memorizzato.

Autenticazione
Autenticare ogni richiesta con la chiave API segreta nell’intestazione
X-API-Key, tramite HTTPS. Le chiavi si creano e si gestiscono dalla
dashboard. Vedere
Autenticazione per i dettagli.
Richiesta
L’endpoint accetta un corpo della richiesta multipart/form-data.
filefilerequiredIl documento PDF di input.
page_orderstringrequiredL’ordine delle pagine desiderato, scritto con la sintassi ordinata delle
pagine, ad esempio 3,1,2. Le pagine omesse vengono
scartate e una pagina indicata più di una volta viene ripetuta. Massimo
1000 caratteri.
Ordine delle pagine
page_order viene letto come un elenco ordinato, non come un insieme: le
pagine escono esattamente nell’ordine indicato. Una pagina indicata due volte
viene emessa due volte e qualsiasi pagina omessa viene scartata. Un intervallo
può anche procedere a ritroso: 10..5 va dalla pagina 10 alla pagina 5.
I numeri sono in base 1 e un indice negativo conta dalla fine: -1 è quindi
l’ultima pagina.
page_order |
Produce |
|---|---|
3,1,2 |
Le pagine 3, 1 e poi 2 |
2.. |
Dalla pagina 2 all’ultima pagina, in ordine |
-1,1..-2 |
L’ultima pagina, poi tutte quelle che la precedono |
1,1,2.. |
La pagina 1 due volte, poi dalla pagina 2 in avanti |
10..5 |
Dalla pagina 10 alla 5, in ordine inverso |

completo, comprese le differenze tra il page_order ordinato e il campo
pages, che si basa su un insieme.

Errori
Le richieste non riuscite restituiscono un corpo application/problem+json.
L’errore più frequente su questo endpoint è un 400, restituito quando
page_order è malformato o indica una pagina che il documento non contiene.
L’oggetto errors identifica il campo:
{
"type": "https://www.pdfblocks.com/docs/api/v1/error/400",
"title": "One or more validation errors occurred.",
"status": 400,
"errors": {
"page_order": ["The page_order field references a page that does not exist in the document."]
}
}Una X-API-Key mancante o non valida restituisce un 401. Vedere
Errori per tutti i codici di stato e la forma completa della
risposta.
