This topic describes how to download an object to a local file.
The following code provides an example on how to download an object to a specified local file:
// This example uses the endpoint of the China (Hangzhou) region. Specify the actual endpoint based on your requirements. String endpoint = "http://oss-cn-hangzhou.aliyuncs.com"; // Security risks may arise if you use the AccessKey pair of an Alibaba Cloud account to log on to OSS, because the account has permissions on all API operations. We recommend that you use your RAM user's credentials to call API operations or perform routine operations and maintenance. To create a RAM user, log on to https://ram.console.aliyun.com. String accessKeyId = "<yourAccessKeyId>"; String accessKeySecret = "<yourAccessKeySecret>"; String bucketName = "<yourBucketName>"; String objectName = "<yourObjectName>"; // Create an OSSClient instance. OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret); // Download an object to a local file. If the name of the object is the same as that of the local file, the object will replace the local file. If the name of the object is different from that of the local file, the object will be downloaded. ossClient.getObject(new GetObjectRequest(bucketName, objectName), new File("<yourLocalFile>")); // Shut down the OSSClient instance. ossClient.shutdown();
