OBS .NET SDK provides abundant APIs for downloading objects in the following modes: Performing a Streaming Download Performing a Partial Download Performing an Asynchronous Download Performing a Conditioned Download Performing a Resumable Download You can call ObsClient.GetObject
This is because original images to be processed are downloaded from the bucket over the intranet by OBS, and the logging function records intranet IP addresses. Download requests also incur costs. Parent topic: Image Processing

// require 'obs-autoloader.php'; // Declare the namespace. use Obs\ObsClient; // Create an instance of ObsClient. $obsClient = new ObsClient ( [ //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways.
OBS can be used to process images in a stable, secure, efficient, easy-of-use, and cost-efficient manner.
// require 'obs-autoloader.php'; // Declare the namespace. use Obs\ObsClient; // Create an instance of ObsClient. $obsClient = new ObsClient([ //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways.
Set cloud_url in the format of obs://bucketname when downloading all objects in a bucket.
Otherwise, access OBS as an anonymous user. The "access keys are not empty" means both AK and SK are not empty, but the token can be empty.
OBS does not involve folders like in a file system. All elements in buckets are objects. To create a folder in OBS is essentially to create an object whose size is 0 and whose name ends with a slash (/).

OBS supports five types of bucket or object ACL configuration items, as listed in the following table: Permission Description Value in OBS BrowserJS SDK READ A grantee with this permission for a bucket can obtain the list of objects in the bucket and the metadata of the bucket.
OBS PHP SDK provides abundant APIs for object download in the following modes: Performing a Text-Based Download Performing a Streaming Download Performing a File-Based Download Performing a Partial Download Performing a Conditioned Download You can call ObsClient->getObject to download

If you delete an object with a version ID specified when versioning is enabled or you delete an object when versioning is not enabled, OBS permanently deletes the object, and you cannot recover it. For details, see Versioning Overview. Parent topic: Versioning
The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.

When temporary AK and SK are used to access OBS, the token must be carried.
It is provided for the OBS server to verify data integrity. The OBS server will compare this MD5 value with the MD5 value calculated based on the object data. If the two values are not the same, HTTP status code 400 is returned.
Error Responses If the AK or signature was invalid, OBS returns 403 Forbidden and the error code is AccessDenied. If the bucket was not found, OBS returns 404 Not Found and the error code is NoSuchBucket.
Billing Analysis An ECS can access OBS over the Internet or an intranet. Access over an intranet requires that the ECS and OBS buckets be in the same region.
