SDK Common Results (SDK for Node.js)

After you call an API in an instance of the ObsClient class, a common result object will be returned if no exception is thrown. The following table lists the fields of the object:

Parameter		Type	Description
CommonMsg		Object	Common information generated after the API is called, including HTTP status code and error code.
-	Status	Number	HTTP status code. If the value is smaller than 300, the operation succeeds. Otherwise, the operation fails.
	Code	String	Error code returned by the OBS server. If Status is smaller than 300, the value is null.
	Message	String	Error description returned by the OBS server. If Status is smaller than 300, the value is null.
	HostId	String	Requested Server ID. If Status is smaller than 300, the value is null.
	RequestId	String	Request ID returned by the OBS server
	Id2	String	Request ID2 returned by the OBS server
	Indicator	String	Detailed error code returned by the OBS server. If Status is smaller than 300, the value is null.
InterfaceResult		Object	Result data generated after the operation is successful. If Status is greater than 300, the value is null.
-	RequestId	String	Request ID returned by the OBS server.
	Id2	String	Request ID2 returned by the OBS server
	Other fields	For details, see the Response area in the corresponding section.

Sample code:

// Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use the source code to install the client.
// var ObsClient = require('./lib/obs');

// Create an instance of ObsClient.
const obsClient = new ObsClient({
    //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways. Using hard coding may result in leakage.
    //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
    access_key_id: process.env.ACCESS_KEY_ID,
    secret_access_key: process.env.SECRET_ACCESS_KEY,
    //EU-Dublin is used here as an example. Replace it with the one in your actual situation.
    server: 'https://obs.eu-west-101.myhuaweicloud.com'
    
});

// Call APIs to perform operations, such as downloading an object.
obsClient.getObject({
       Bucket : 'bucketname',
       Key : 'objectname',
}, (err, result) => {
       if(!err){
              if(result.CommonMsg.Status < 300){
                    // Obtain RequestId.
                     console.log('RequestId-->' + result.InterfaceResult.RequestId);
                     // Obtain other parameters.
                     console.log('Content-->' + result.InterfaceResult.Content.toString());
              }else{
                     // Obtain Code and Message.
                     console.log('Code-->' + result.CommonMsg.Code); 
                     console.log('Message-->' + result.CommonMsg.Message);
              }
       }
});
