我正在尝试将测试记录从 Android 保存到亚马逊 dynamodb 表。
Context mContext = this.getApplicationContext();
CognitoCachingCredentialsProvider cognitoProvider = new CognitoCachingCredentialsProvider(
mContext, // get the context for the current activity
"xxxxxxxxxxxxxx",
"us-east-1:dsfhjhsd-sdfsfds-sdffds-dsffs",
"arn:aws:iam::7777777777:role/Cognito_CustMobAnalyticsUnauth_DefaultRole",
"YOUR AUTHENTICATED ARN HERE",
Regions.US_EAST_1
);
try {
AmazonDynamoDBClient ddb = new AmazonDynamoDBClient(cognitoProvider);
//ddb.setRegion(Region.getRegion(Regions.US_EAST_1));
DynamoDBMapper mapper = new DynamoDBMapper(ddb);
androTest mytest = new androTest();
mytest.setMyKey("testKey-1");
try {
mapper.save(mytest);
} catch (AmazonServiceException ex) {
Log.e("CustomError", "---> " + ex.getLocalizedMessage());
}
} catch (Exception e) {
// This will catch any exception, because they are all descended from Exception
Log.e("CustomError", "---> " + e.getLocalizedMessage());
Log.e("CustomError", "---> " + e.getMessage());
}
我在执行时收到以下消息并且数据未更新。我正在使用未经身份验证的 arn。
D/CognitoCachingCredentialsProvider﹕ Loading credentials from SharedPreferences
D/CognitoCachingCredentialsProvider﹕ No valid credentials found in SharedPreferences
E/CustomError﹕ ---> null
