AWS SDK for JAVA，在Eucalyptus中提供IAM服务

Question

我正试图使用亚马逊AWS SDK开发Eucalyptus，但我总是被拒绝访问：public class App｛

public static  AmazonEC2 ec2;
public static AmazonS3 s3;
public static  AmazonIdentityManagement identityManagement;
private static String ACCESS_KEY;
private static String SECRET_KEY;
private static String IDENTITY_END_POINT;
public static void init(){
    ACCESS_KEY="myaccesskey";
        SECRET_KEY="mysecretkey";
    IDENTITY_END_POINT="http://192.168.1.101:8773/services/Euare";
    AWSCredentials myCredential = new BasicAWSCredentials(ACCESS_KEY,SECRET_KEY);
    //ec2 = new AmazonEC2Client(myCredential);
   s3 = new AmazonS3Client(myCredential);
   //ec2.setEndpoint(EC2_END_POINT);    
   s3.setEndpoint(Walrus_END_POINT);
    identityManagement=new AmazonIdentityManagementClient(myCredential);
    identityManagement.setEndpoint(IDENTITY_END_POINT);  
  }
public static void main(String[] args) {
    // TODO Auto-generated method stub
    init();
     List<Bucket> buckets = s3.listBuckets();
        System.out.println("List of all buckets in your cloud:n");
        for (Bucket bucket : buckets) {
            System.out.println(bucket.getName()+"n");
   }
       CreateUserRequest createUserRequest=new        CreateUserRequest().withPath("/").withUserName("summer");
CreateUserResult createUserResult=identityManagement.createUser(createUserRequest); 

}}这就是我得到的错误：

线程"main"中的异常状态代码：404，AWS服务：AmazonIdentityManagement，AWS请求ID:null，AWS错误代码：null，AWS故障消息：null网址：com.amazonaws.http://AmazonHttpClient.handleErrorResponse（AmazonHttpClient.java：614）网址：com.amazonaws.http://AmazonHttpClient.executeHelper（AmazonHttpClient.java:312）网址：com.amazonaws.http://AmazonHttpClient.exexecute（AmazonHttpClient.java：165）网址：com.amazonaws.services.identitymanagementAmazonIdentityManagementClient.ioke（AmazonIdedentityManagementClient.java:3130）网址：com.amazonaws.services.identitymanagementAmazonIdentityManagementClient.getUser（AmazonIdedentityManagementClient.java:1201）在com.test2.Group.main（Group.java:107）

我不确定使用IAM API时会导致404的原因，您发布的代码似乎与发布的异常不匹配。

您没有说明您使用的是Eucalyptus和AWS Java SDK的哪个版本，但对于某些版本，有必要在端点URL中添加/，以便AWS Java SDK正确计算签名，例如，对于IAM：

"http://$EXAMLE:8773/services/Euare/"

然而，我不认为这会导致404问题。

您可以在此处找到有关将AWS Java SDK与Eucalyptus一起使用的详细信息：

带有Eucalyptus的AWS Java SDK的单元测试如下：

这包括IAM/STS服务的部分覆盖范围。
