O OSS pode enviar callbacks ao servidor de aplicativos após a conclusão das tarefas de upload simples. Para configurar callbacks de upload, basta especificar os parâmetros de callback relevantes na solicitação de upload enviada ao OSS.

O exemplo de código a seguir mostra como configurar um callback ao fazer upload de um arquivo local:

<?php

// Introduce autoload files to load dependent libraries.
require_once __DIR__ . '/../vendor/autoload.php';

use AlibabaCloud\Oss\V2 as Oss;

// Specify descriptions for command line parameters.

    "endpoint" => ['help' => The domain names that other services can use to access OSS.', 'required' => False], // (Optional) Specify the endpoint that can be used by other services to access OSS.
    "bucket" => ['help' => The name of the bucket, 'required' => True], // (Required) Specify the name of the bucket.
    "key" => ['help' => The name of the object, 'required' => True], // (Required) Specify the name of the object.
];

// Convert the parameter descriptions to a long options list required by getopt.
// Add a colon (:) to the end of each parameter to indicate that a value is required.
$longopts = \array_map(function ($key) {
    return "$key:";

// Parse the command line parameters.
$options = getopt("", $longopts);

// Check whether the required parameters are configured.
