AmazonEC2例外

Question

为什么在尝试获取网络接口时会出现这种情况？

   com.amazonaws.services.ec2.model.AmazonEC2Exception: null (Service: AmazonEC2; Status Code: 400; Error Code: 400 Bad Request; Request ID: null)

我正在使用下面的代码。这只是一个独立的测试代码。

AmazonEC2 amazonEC2 = getEC2Client();
    try {
        DescribeInstancesResult result = amazonEC2.describeInstances();
        for(Reservation reservation : result.getReservations()){
            System.out.println(reservation.getInstances());
        }

    }catch (AmazonEC2Exception e){
        e.printStackTrace();
    }

protected static AmazonEC2 getEC2Client() {
    conf = new ClientConfiguration();
    conf.setConnectionTimeout(5000);
    conf.setSocketTimeout(20000);
    conf.setMaxErrorRetry(2);
    AmazonEC2 client;
    if (access_id == null && access_key == null) {
        client =  AmazonEC2ClientBuilder.standard().withClientConfiguration(conf).withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://iam.amazonaws.com", "us-east-1"))
                .withCredentials(new InstanceProfileCredentialsProvider(false))
                .build();
    } else {
        client = AmazonEC2ClientBuilder.standard().withClientConfiguration(conf).withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://iam.amazonaws.com","us-east-1"))
                .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(access_id, access_key)))
                .build();
    }
    return client;
}

我可以访问同一类中的用户列表，但不能访问与Describe *相关的​​内容。有人可以发表评论吗？

尝试使用.withRegion(..)，不要使用.withEndpointConfiguration(...)。也许你使用了不正确的端点定义。
