Viewing 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 the API Reference.

You can call ObsClient.getBucketCors to view CORS rules of a bucket.

This example views the CORS rule of bucket bucketname.

The example code is as follows:

// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// 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.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
String endPoint = "https://your-endpoint";
// Create an instance of ObsClient.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);


BucketCors cors = obsClient.getBucketCors("bucketname");
for(BucketCorsRule rule : cors.getRules()){
    Log.i("GetBucketCors","\t" + rule.getId());
    Log.i("GetBucketCors","\t" + rule.getMaxAgeSecond());
    Log.i("GetBucketCors","\t" + rule.getAllowedHeader());
    Log.i("GetBucketCors","\t" + rule.getAllowedOrigin());
    Log.i("GetBucketCors","\t" + rule.getAllowedMethod());
    Log.i("GetBucketCors","\t" + rule.getExposeHeader());
}
