(JavaScript) OSS List Bucket Objects (Alibaba Cloud)

See more Alibaba Cloud OSS Examples

The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

// This example assumes the Chilkat HTTP API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var http = new CkHttp();

// Insert your AccessKey ID here:
http.AwsAccessKey = "access-key";

// Insert your AccessKey Secret here:
http.AwsSecretKey = "secret-key";

// To list objects in a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
// See Alibaba Object Storage Service Regions and Endpoints
http.AwsEndpoint = "oss-us-east-1.aliyuncs.com";

var xml = new CkXml();

// If the response status code was not 200, then the XML response is not a 
// listing of objects, but instead contains error information.

    console.log(xml.GetXml());
    console.log("Failed.");
