Use o OSS SDK for PHP, crie buckets, faça upload de objetos e baixe-os via HTTP.
Crie um bucket
Um bucket é um namespace globalmente exclusivo no OSS usado para armazenar objetos.
Nota
Endpoints: Regions and Endpoints. Convenções de nomenclatura de buckets: Basic concepts.
O código a seguir permite que você crie um bucket.
<?php
if (is_file(__DIR__ . '/../autoload.php')) {
require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
require_once __DIR__ . '/../vendor/autoload.php';
}
use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;
// Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured.
$provider = new EnvironmentVariableCredentialsProvider();
// In this example, the endpoint of the China (Hangzhou) region is used. Specify your actual endpoint.
$endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// Specify the name of the bucket. Example: examplebucket.
$bucket= "examplebucket";
try {
$config = array(
"provider" => $provider,
"endpoint" => $endpoint,
"signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
"region"=> "cn-hangzhou"
);
$ossClient = new OssClient($config);
// Set the storage class of the bucket to Infrequent Access (IA). The default storage class is Standard.
$options = array(
OssClient::OSS_STORAGE => OssClient::OSS_STORAGE_IA
);
// Set the ACL of the bucket to public-read. The default bucket ACL is private.
$ossClient->createBucket($bucket, OssClient::OSS_ACL_TYPE_PUBLIC_READ, $options);
} catch (OssException $e) {
printf(__FUNCTION__ . ": FAILED\n");
printf($e->getMessage() . "\n");
return;
}
print(__FUNCTION__ . ": OK" . "\n"); Faça upload de um objeto
O código a seguir faz o upload de um objeto para o OSS por streaming.
<?phpif (is_file(__DIR__ . '/../autoload.php')) {
require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
require_once __DIR__ . '/../vendor/autoload.php';
}
use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\Core\OssException;
// Obtain access credentials from environment variables.$provider = new EnvironmentVariableCredentialsProvider();
// Specify the endpoint of the region. For example, https://oss-cn-hangzhou.aliyuncs.com.$endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
// Specify the bucket name.$bucket= "examplebucket";
// Specify the object key. Do not include the bucket name.$object = "exampledir/exampleobject.txt";
// Specify the content to upload.$content = "Hello OSS";
// Optional: set the object ACL to private and add custom metadata.$options = array(
OssClient::OSS_HEADERS => array(
'x-oss-object-acl' => 'private',
'x-oss-meta-info' => 'yourinfo'
),
);
try {
$config = array(
"provider" => $provider,
"endpoint" => $endpoint,
"signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
"region" => "cn-hangzhou"
);
$ossClient = new OssClient($config);
$ossClient->putObject($bucket, $object, $content, $options);
} catch (OssException $e) {
printf(__FUNCTION__ . ": FAILED\n");
printf($e->getMessage() . "\n");
return;
}
print(__FUNCTION__ . ": OK" . "\n");O método putObject faz o upload do conteúdo para a chave de objeto especificada. Use a opção OssClient::OSS_HEADERS e defina a ACL do objeto ou adicione metadados personalizados.
Baixe um objeto
O código a seguir permite que você baixe um objeto.
<?php

use OSS\OssClient;
// Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set.
$provider = new EnvironmentVariableCredentialsProvider();
// Specify the Endpoint for the region where the bucket is located. For example, for the China (Hangzhou) region, set the Endpoint to https://oss-cn-hangzhou.aliyuncs.com.
$endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
// Specify the bucket name. Example: examplebucket.
$bucket= "examplebucket";
// Specify the full path of the object. Do not include the bucket name. Example: testfolder/exampleobject.txt.
$object = "testfolder/exampleobject.txt";
// Download the object to a local file named examplefile.txt and save it to the specified local path (D:\\localpath). If the local file exists, it is overwritten. If it does not exist, it is created.
// If you do not specify a local path, the downloaded file is saved to the local path of the project where the sample program resides.
$localfile = "D:\\localpath\\examplefile.txt";
$options = array(
OssClient::OSS_FILE_DOWNLOAD => $localfile
);
// Use a try-catch block to catch exceptions. If an exception is caught, the download failed. If no exception is caught, the download is successful.

Liste objetos
O código a seguir lista os objetos em um bucket. Por padrão, a operação retorna até 100 objetos.

Exclua um objeto
