如何使用Android SDK为Amazon推送SNS设置应用ARN

Question

我正在尝试注册我的Android设备以接收推送通知，但亚马逊服务器返回错误，说它无法找到我的PlatformApplicationArn。我使用他们的sdk设置它，但它似乎没有找到它。

这是错误： AWS错误消息：无效参数：PlatformApplicationArn原因：没有必需参数的值

这是发送它的代码：

String platformApplicationArn = "arn:aws:sns:us-east-1:897955111111:app/GCM/com.myapp";
AWSCredentials awsCredentials = new BasicAWSCredentials("XXXXXXXX", "XXXXXXXXXXXXXXXXXXXXX");
pushClient = new AmazonSNSClient(awsCredentials);
CreatePlatformEndpointRequest createPlatformEndpointRequest = new CreatePlatformEndpointRequest();
String customPushData = "my custom data";
CreatePlatformEndpointRequest platformEndpointRequest = new CreatePlatformEndpointRequest();
platformEndpointRequest.setCustomUserData(customPushData);
platformEndpointRequest.setToken(pushNotificationRegId);
platformEndpointRequest.setPlatformApplicationArn(platformApplicationArn);
CreatePlatformEndpointResult result = pushClient.createPlatformEndpoint(createPlatformEndpointRequest);

Answer 1

您有2个实例CreatePlatformEndpointRequest并且您将令牌和applicationArn设置为一个但使用另一个用于您的SNSClient请求，因此它缺少必需的参数。

String platformApplicationArn = "arn:aws:sns:us-east-1:897955111111:app/GCM/com.myapp";
AWSCredentials awsCredentials = new BasicAWSCredentials("XXXXXXXX", "XXXXXXXXXXXXXXXXXXXXX");
AmazonSNSClient pushClient = new AmazonSNSClient(awsCredentials);
//probably no need for this
String customPushData = "my custom data";

CreatePlatformEndpointRequest platformEndpointRequest = new CreatePlatformEndpointRequest();

platformEndpointRequest.setCustomUserData(customPushData);
platformEndpointRequest.setToken(pushNotificationRegId);
platformEndpointRequest.setPlatformApplicationArn(platformApplicationArn);

CreatePlatformEndpointResult result = pushClient.createPlatformEndpoint(platformEndpointRequest);

此外，除非您的SNS应用区域为US_EAST_1，否则我发现您必须手动设置区域，否则您将收到不匹配的区域错误响应，因此在致电createPlatformEndpoint()之前，请按照以下方式设置您的区域：< / p>

//Replace with whatever region your app is
pushClient.setRegion(Region.getRegion(Regions.US_WEST_2));
