Overview

This document provides an overview of APIs and SDK code samples for creating a bucket.
Caution:
We recommend you use a temporary key as instructed in Generating and Using Temporary Keys to call the SDK for security purposes. When you apply for a temporary key, follow the Notes on Principle of Least Privilege to avoid leaking resources besides your buckets and objects.
If you must use a permanent key, we recommend you follow the Notes on Principle of Least Privilege to limit the scope of permission on the permanent key.

Creating a Bucket

Feature description

This API is used to create a bucket under the specified account. You can create multiple buckets under the same user account. The maximum number is 200 (regardless of region). There is no limit to the number of objects in the bucket. Bucket creation is a low-frequency operation. We recommended you create a bucket in the console and perform object operations in the SDK.

Sample code

using COSXML.Common;
using COSXML.Model.Bucket;
using COSXML.Auth;
using System;
using COSXML;

namespace COSSnippet
{
    public class PutBucketModel {

      private CosXml cosXml;

      PutBucketModel() {
        CosXmlConfig config = new CosXmlConfig.Builder()
          .SetRegion("COS_REGION") // Set the default region. For abbreviations of COS regions, visit https://cloud.tencent.com/document/product/436/6224. 
          .Build();

        string secretId = "SECRET_ID";   // SecretId of the TencentCloud API. For more information about how to obtain the API key, see https://console.cloud.tencent.com/cam/capi.
        string secretKey = "SECRET_KEY"; // SecretKey of the TencentCloud API. For more information about how to obtain the API key, see https://console.cloud.tencent.com/cam/capi.
        long durationSecond = 600;          // Validity period of the request signature in seconds
        QCloudCredentialProvider qCloudCredentialProvider = new DefaultQCloudCredentialProvider(secretId, 
          secretKey, durationSecond);

        this.cosXml = new CosXmlServer(config, qCloudCredentialProvider);
      }

      /// Create a bucket.
      public void PutBucket()
      {
        //.cssg-snippet-body-start:[put-bucket]
        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";
          PutBucketRequest request = new PutBucketRequest(bucket);
          // Execute the request
          PutBucketResult result = cosXml.PutBucket(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());
        }

        //.cssg-snippet-body-end
      }

      // .cssg-methods-pragma

      static void Main(string[] args)
      {
        PutBucketModel m = new PutBucketModel();

        /// Create a bucket.
        m.PutBucket();
        // .cssg-methods-pragma
      }
    }
}
