Setting CORS Rules

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

You can call ObsClient->setBucketCors to set CORS rules for a bucket. If the bucket is configured with CORS rules, the newly set ones will overwrite the existing ones. Sample code is as follows:

<?php

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with the source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
use Obs\ObsException;
// Create an ObsClient instance.
$obsClient = new ObsClient([ 
    // Obtain an AK/SK pair using environment variables (recommended) or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
    'key' => getenv('ACCESS_KEY_ID'),
    'secret' => getenv('SECRET_ACCESS_KEY'),
    'endpoint' => 'https://your-endpoint',
]);

try {
    $resp = $obsClient->setBucketCors([ 
        'Bucket' => 'bucketname',
        'CorsRules' => [ 
             [ 
                  'ID' => 'rule1',
                  // Specify the allowed request methods, which can be GET, PUT, DELETE, POST, or HEAD.
                  'AllowedMethod' => [ 'GET','HEAD','PUT'],
                  // Specify the allowed request origins.
                  'AllowedOrigin' => ['http://www.a.com', 'http://www.b.com'],
                  // Specify whether headers specified in Access-Control-Request-Headers in an OPTIONS preflight request can be used.
                  'AllowedHeader' => [ 'x-obs-header'],
                  // Specify the headers that can be accessed by users from the application.
                  'ExposeHeader' => ['x-obs-expose-header'],
                  // Specify the browser's cache time of the returned results of OPTIONS preflight requests for specific resources, in seconds.
                  'MaxAgeSeconds' => 60 
              ]
        ] 
    ]);
    printf("RequestId:%s\n", $resp['RequestId']);
    printf("Status:%s\n", $resp['Status']); // The returned value of Status can be Enabled or Suspended. If versioning has never been configured for the bucket, the value is empty.
} catch (ObsException $e) {
    // If the operation fails, obtain the exception details.
    printf("SetBucketCorsFailed: Status:%d, Code:%s, Message:%s\n",
         $e->getStatusCode(), $e->getExceptionCode(), $e->getExceptionMessage());
} finally {
    // Close ObsClient to release resources.
    $obsClient->close();
}

• Use the CorsRules parameter to set CORS rules for a bucket.
• Both AllowedOrigin and AllowedHeader can contain one wildcard character (*). The wildcard character (*) indicates that all origins or headers are allowed.
