Obtaining Customized Metadata

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

After an object is successfully downloaded, its customized data is returned. Sample code is as follows:

// Create an instance of ObsClient.
ObsClient client = new ObsClient("*** Provide your Access Key ***", "*** Provide your Secret Key ***", "https://your-endpoint");
// Download an object.
try
{
    GetObjectRequest request = new GetObjectRequest()
    {
        BucketName = "bucketname",
        ObjectKey = "objectname",
    };
    using (GetObjectResponse response = client.GetObject(request))
    {
        //Obtain the customized metadata of the object.
        foreach (string key in response.Metadata.Keys)
        {
            Console.WriteLine("key is :" + key + " value is: " + response.Metadata[key]);
        }
        string dest = "savepath";
        if (!File.Exists(dest))
        {
            response.WriteResponseStreamToFile(dest);
        }
        Console.WriteLine("Get object response: {0}", response.StatusCode);
    }
}
catch (ObsException ex)
{
   Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
   Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
