For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy. The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
Using OBS to Decouple Storage from Compute in Big Data Scenarios OBSA-HDFS Other OBS tools You can use tools provided by OBS, such as obsutil and OBS Browser+, to use parallel file systems. Parallel file systems do not support s3fs.
Follow-up Procedure To perform read operations on OBS Console or OBS Browser+, you must add the obs:bucket:ListAllMyBuckets (for listing buckets) and obs:bucket:ListBucket (for listing objects in a bucket) permissions to the custom IAM policy. obs:bucket:ListAllMyBuckets applies to

For details about how to query the bucket version, see Checking OBS Version (OBS 2.0 or OBS 3.0). Archive objects in a folder must be restored in the bucket before they can be downloaded.
If OBS is accessed from a public network, traffic of elastic IP address (EIP) bound to the ECS is also generated. Traffic of the ECS elastic network interface is free. For details about OBS billing, see OBS Billing Overview.
return new Blob([u8arr], { type: mime }); }; // obsClient indicates an instance of the OBS client. const uploadBase64Img = function uploadBase64Img(obsClient) { // Specify the content in Base64 format.
Online decompression requires that you create an IAM agency to delegate OBS to access data in the bucket. The permissions the agency should assign to OBS include obs:object:PutObject, obs:object:GetObject, and obs:object:AbortMultipartUpload.
The network delay between the client and the OBS server is too long. Check the health status of the network between the client and the OBS server. Parent topic: Troubleshooting
(SDK for Node.js) To be compatible with AWS S3, the source code of OBS SDK for Go contains the acs.amazonaws.com keyword. The SDK only takes this keyword as a constant and does not process or access it. You can ignore this keyword. The figure below gives an example.
