Question

得到例外：

Unable to execute HTTP request: Unable to resolve host "cognito-identity.eu-central-1.amazonaws.com": No address associated with hostname
Unable to resolve host "cognito-identity.eu-central-1.amazonaws.com": No address associated with hostname

代码如下：

        // Initialize the Amazon Cognito credentials provider
        CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
                getApplicationContext(), // Application Context
                getResources().getString(R.string.AWS_IdentityPoolId), // Identity Pool ID
                Regions.EU_CENTRAL_1 // Region enum
        );

Answer 1

这是地区的“公正”问题。由于我的Cognito位于爱尔兰，而我的Bucket位于Franckfurt，因此很容易混淆。所以你可能会小心区域。在可能的情况下：

// Initialize the Amazon Cognito credentials provider
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
       getApplicationContext(), // Application Context
       getResources().getString(R.string.AWS_IdentityPoolId), // Identity Pool ID
       Regions.EU_WEST_1 // Region enum
);

Answer 2

仅供参考，尚未在EU_CENTRAL_1（法兰克福）提供Cognito Identity。结帐AWS Service Region Availability。就像安东尼所说，Cognito Identity不必与其他服务处于同一区域。请始终选择离您最近的地区以获得更好的体验。
