Performing a Text-based Download

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.

This example downloads object objectname from bucket bucketname.

The example code is as follows:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    // 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.
    // The front-end code does not have the process environment variable, so you need to use a module bundler like webpack to define the process variable.
    // 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.
    access_key_id: process.env.AccessKeyID,
    secret_access_key: process.env.SecretAccessKey,
    // Replace the example endpoint with the actual one in your case.
    server: 'https://obs.ap-southeast-1.myhuaweicloud.com'
});
 
obsClient.getObject({ 
       Bucket : 'bucketname', 
       Key : 'objectname'
}, function (err, result) { 
       if(err){ 
              console.error('Error-->' + err); 
       }else{ 
              console.log('Status-->' + result.CommonMsg.Status); 
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                   // Read the object content.
                   console.log('Object Content:'); 
                   console.log(result.InterfaceResult.Content); 
              }
       } 
});

In the returned result of a text-based download, InterfaceResult.Content is a String object.
