Performing a File-Based 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.

File-based upload uses local files as the data source of objects.

This example uploads local file localfile to bucket bucketname as object objectname.

The example 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. 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 ObsClient instance.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Upload a file.
try
{
    PutObjectRequest request = new PutObjectRequest()
    {
        BucketName = "bucketname",  //Name of the bucket for storing the file to be uploaded
        ObjectKey = "objectname",   //Name of the file to be uploaded (The file name is the complete path of the file in the bucket, for example, folder/test.txt. The path does not contain the bucket name.)
        FilePath = "localfile",//Path of the local file to be uploaded, in which the file name must be specified
    };
    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);
}

• The content to be uploaded cannot exceed 5 GB.
