android - 关于 Amazon SimpleDB，选择函数

Question

我使用这些代码来连接 SimpleDB 和查询数据。我可以在 SQL Scrap Book 中运行查询，结果正常。但是当我在 Eclipse 中运行它时，我收到错误消息:

"12-18 22:01:57.401: I/com.amazonaws.request(402): Received error response: Status Code: 400, AWS Request ID: d68b7fcc-cd4a-7def-602c-96ad189d8fcf, AWS Error Code: NoSuchDomain, AWS Error Message: The specified domain does not exist."

你知道吗？

//1. Creating a SimpleDB Client
AWSCredentials credentials = new BasicAWSCredentials( ACCESS_KEY_ID, SECRET_KEY );
AmazonSimpleDBClient sdbClient = new AmazonSimpleDBClient( credentials);        

//2. Select
String nextToken = null;
SelectRequest selectRequest = new SelectRequest( "select * from mydomain" ).withConsistentRead( true );
selectRequest.setNextToken( nextToken );        
SelectResult response = sdbClient.select( selectRequest );
nextToken = response.getNextToken(); 

Answer 1

在请求域数据之前，您需要指定服务器区域端点。 Amazon Simple DB 支持 7 个区域端点。

区域、端点

"US-East(Northern Virginia)", "sdb.amazonaws.com"
"EU(Ireland)", "sdb.eu-west-1.amazonaws.com"
"US-West(Northern California)", "sdb.us-west-1.amazonaws.com"
"Asia Pacific(Singapore)", "sdb.ap-southeast-1.amazonaws.com"
"Asia Pacific(Tokyo)", "sdb.ap-northeast-1.amazonaws.com"
"US West(Oregon)", "sdb.us-west-2.amazonaws.com"
"South America(Sao Paulo)", "sdb.sa-east-1.amazonaws.com"

如何设置区域终点

BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(sAccessKey, sSecretKey);
AmazonSimpleDBClient amazonSimpleDBClient = new AmazonSimpleDBClient(basicAWSCredentials);
amazonSimpleDBClient.setEndpoint(Endpoint);
