(C#) OSS List Bucket Objects (Alibaba Cloud)See more Alibaba Cloud OSS ExamplesDemonstrates how to list the objects in a bucket. The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.
// This example assumes the Chilkat HTTP API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Http http = new Chilkat.Http(); // 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"; string bucketName = "chilkat"; string strXml = http.S3_ListBucketObjects(bucketName); if (http.LastMethodSuccess != true) { Debug.WriteLine(http.LastErrorText); return; } Debug.WriteLine("Response status code = " + Convert.ToString(http.LastStatus)); Chilkat.Xml xml = new Chilkat.Xml(); bool success = xml.LoadXml(strXml); if (success != true) { Debug.WriteLine(xml.LastErrorText); return; } // If the response status code was not 200, then the XML response is not a // listing of objects, but instead contains error information. if (http.LastStatus != 200) { Debug.WriteLine(xml.GetXml()); Debug.WriteLine("Failed."); return; } // A sample response is shown below. Debug.WriteLine(xml.GetXml()); Debug.WriteLine("----"); // Use this online tool to generate parsing code from sample XML: // Generate Parsing Code from XML // <?xml version="1.0" encoding="UTF-8"?> // <ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> // <Name>chilkat</Name> // <Prefix/> // <Marker/> // <MaxKeys>1000</MaxKeys> // <IsTruncated>false</IsTruncated> // <Contents> // <Key>orchard.json</Key> // <LastModified>2021-10-29T16:58:12.000Z</LastModified> // <ETag>"303FB46CF341094FEF6274B7789CD6AA"</ETag> // <Size>22</Size> // <StorageClass>STANDARD</StorageClass> // <Owner> // <ID>5035535379748121</ID> // <DisplayName>5035535379748121</DisplayName> // </Owner> // </Contents> // <Contents> // <Key>seahorse.jpg</Key> // <LastModified>2021-10-29T16:52:01.000Z</LastModified> // <ETag>"A8551F0A5437F43A796FCA7623EE9232"</ETag> // <Size>24388</Size> // <StorageClass>STANDARD</StorageClass> // <Owner> // <ID>5035535379748121</ID> // <DisplayName>5035535379748121</DisplayName> // </Owner> // // </Contents> // </ListBucketResult> string Key; string LastModified; string ETag; string SizeDecimalStr; string StorageClass; string ID; string DisplayName; string ListBucketResult_xmlns = xml.GetAttrValue("xmlns"); string Name = xml.GetChildContent("Name"); int MaxKeys = xml.GetChildIntValue("MaxKeys"); string IsTruncated = xml.GetChildContent("IsTruncated"); int i = 0; int count_i = xml.NumChildrenHavingTag("Contents"); while (i < count_i) { xml.I = i; Key = xml.GetChildContent("Contents[i]|Key"); LastModified = xml.GetChildContent("Contents[i]|LastModified"); ETag = xml.GetChildContent("Contents[i]|ETag"); SizeDecimalStr = xml.GetChildContent("Contents[i]|Size"); StorageClass = xml.GetChildContent("Contents[i]|StorageClass"); ID = xml.GetChildContent("Contents[i]|Owner|ID"); DisplayName = xml.GetChildContent("Contents[i]|Owner|DisplayName"); i = i + 1; } |
