Setting CORS Configuration

Description

This API is used to set the CORS configuration of a specified bucket.

Sample code

try
{
  // Bucket name in the format of `BucketName-APPID`. You can get APPID by referring to https://console.cloud.tencent.com/developer.
  string bucket = "examplebucket-1250000000";
  PutBucketCORSRequest request = new PutBucketCORSRequest(bucket);
  // Set CORS configuration
  COSXML.Model.Tag.CORSConfiguration.CORSRule corsRule = 
    new COSXML.Model.Tag.CORSConfiguration.CORSRule();
  corsRule.id = "corsconfigureId";
  corsRule.maxAgeSeconds = 6000;

  corsRule.allowedOrigins = new List<string>();
  corsRule.allowedOrigins.Add("http://cloud.tencent.com");

  corsRule.allowedMethods = new List<string>();
  corsRule.allowedMethods.Add("PUT");

  corsRule.allowedHeaders = new List<string>();
  corsRule.allowedHeaders.Add("Host");

  corsRule.exposeHeaders = new List<string>();
  corsRule.exposeHeaders.Add("x-cos-meta-x1");

  request.SetCORSRule(corsRule);

  // Execute the request
  PutBucketCORSResult result = cosXml.PutBucketCORS(request);
  // Request succeeded
  Console.WriteLine(result.GetResultInfo());
}
catch (COSXML.CosException.CosClientException clientEx)
{
  // Request failed
  Console.WriteLine("CosClientException: " + clientEx);
}
catch (COSXML.CosException.CosServerException serverEx)
{
  // Request failed
  Console.WriteLine("CosServerException: " + serverEx.GetInfo());
}

Querying CORS Configuration

Description

This API is used to query the CORS configuration of a bucket.

Sample code

try
{
  // Bucket name in the format of `BucketName-APPID`. You can get APPID by referring to https://console.cloud.tencent.com/developer.
  string bucket = "examplebucket-1250000000";
  GetBucketCORSRequest request = new GetBucketCORSRequest(bucket);
  // Execute the request
  GetBucketCORSResult result = cosXml.GetBucketCORS(request);
  // Bucket CORS configuration 
  CORSConfiguration conf = result.corsConfiguration;
}
catch (COSXML.CosException.CosClientException clientEx)
{
  // Request failed
  Console.WriteLine("CosClientException: " + clientEx);
}
catch (COSXML.CosException.CosServerException serverEx)
{
  // Request failed
  Console.WriteLine("CosServerException: " + serverEx.GetInfo());
}

Deleting CORS Configuration

Description

This API is used to delete the CORS configuration of a bucket.

Sample code

try
{
  // Bucket name in the format of `BucketName-APPID`. You can get APPID by referring to https://console.cloud.tencent.com/developer.
  string bucket = "examplebucket-1250000000";
  DeleteBucketCORSRequest request = new DeleteBucketCORSRequest(bucket);
  // Execute the request
  DeleteBucketCORSResult result = cosXml.DeleteBucketCORS(request);
  // Request succeeded
  Console.WriteLine(result.GetResultInfo());
}
catch (COSXML.CosException.CosClientException clientEx)
{
  // Request failed
  Console.WriteLine("CosClientException: " + clientEx);
}
catch (COSXML.CosException.CosServerException serverEx)
{
  // Request failed
  Console.WriteLine("CosServerException: " + serverEx.GetInfo());
}
