Performing a Streaming Upload

If you have any questions during the development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

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. The sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// 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 AccessKeyID and SecretAccessKey.
// 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 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.
