Result Returned via a Callback Function

Description

ObsClient returns the results by using a callback function that contains two parameters in sequence: the exception information parameter and the SDK common result object parameter. If the exception information parameter in the callback function is not null, an error occurs during the API calling. Otherwise, the API calling is complete. In such conditions, you need to obtain the HTTP status code from the SDK common result object parameter to check whether the operation is successful.

Sample Code

This example uploads string Hello OBS to bucket bucketname as object objectkey.

The example code is as follows:

obsClient.putObject({
       Bucket : 'bucketname',
       Key : 'objectkey',
       Body : 'Hello OBS'
}, function(err, result) {
       if(err){
              console.log('Error-->' + err);
       }else{
              if(result.CommonMsg.Status < 300){
                     if(result.InterfaceResult){
                         console.log('Operation Succeed');
                     }
              }else{
                     console.log('Code-->' + result.CommonMsg.Code); 
                     console.log('Message-->' + result.CommonMsg.Message);
                     console.log('HostId-->' + result.CommonMsg.HostId);
                     console.log('RequestId-->' + result.CommonMsg.RequestId);
              }
       }
});
