Performing a Streaming Upload

Streaming upload uses System.IO.Stream as the data source of an object. You can call ObsClient.PutObject to upload the data streams to OBS. Sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Upload a stream.
try
{
    String str = "Hello OBS";
    Stream stream = new MemoryStream(System.Text.Encoding.Default.GetBytes(str));
    PutObjectRequest request = new PutObjectRequest()
    {
        BucketName = "bucketname",
        ObjectKey = "objectname",
        InputStream = stream,
    };
    PutObjectResponse response = client.PutObject(request);
    Console.WriteLine("put object response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}

• To upload a large file, you are advised to use multipart upload.
• The content to be uploaded cannot exceed 5 GB.
