Question

我已经在我的AWS游戏中设置了Unity，它在编辑器和Android上运行良好但是当我在iOS上测试时它似乎无法访问AWS正常。

我已将NSAppTransportSecurity元素添加到我的info.plist文件中，但这似乎没有帮助。

如果有帮助，我使用的服务是Cognito and SimpleDB。

这是我在尝试访问AWS时从Xcode调试器获得的错误：

NullReferenceException：在对象中找到空值实例是必需的。在Amazon.AWSConfigs.get_LoggingConfig（） [0x00000] in：0 at Amazon.Runtime.ClientConfig..ctor（）[0x00000] in：0 在Amazon.CognitoIdentity.AmazonCognitoIdentityConfig..ctor（） [0x00000] in：0 at Amazon.CognitoIdentity.AmazonCognitoIdentityClient..ctor （Amazon.Runtime.AWSCredentials凭据，Amazon.RegionEndpoint region）[0x00000] in：0 at Amazon.CognitoIdentity.CognitoAWSCredentials..ctor（System.String accountId，System.String identityPoolId，System.String unAuthRoleArn， System.String authRoleArn，Amazon.RegionEndpoint region）[0x00000] in ：GameControl.get_Credentials上的0

感谢您的帮助

编辑：

这就是我对Cognito和SimpleDB的引用的设置方式：

    private CognitoAWSCredentials _credentials;

public CognitoAWSCredentials Credentials
{
    get
    {
        if (_credentials == null)
            _credentials = new CognitoAWSCredentials("IDENTITY_POOL_HERE", RegionEndpoint.APSoutheast2);
        return _credentials;
    }
}

private AmazonSimpleDBClient _simpleDB;

public AmazonSimpleDBClient SimpleDB
{
    get
    {
        if (_simpleDB == null)
        {
            //Connect to the DB
                _simpleDB = new AmazonSimpleDBClient(
                    credentials: Credentials, 
                    region: RegionEndpoint.USWest2);
        }
        return _simpleDB;
    }
}

这就是我所说的：

//Disable SSL certification (This prevents "authentication or decryption has failed" error and "Invalid certificate")
    System.Net.ServicePointManager.ServerCertificateValidationCallback +=
       delegate(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate,
                               System.Security.Cryptography.X509Certificates.X509Chain chain,
                               System.Net.Security.SslPolicyErrors sslPolicyErrors)
       {
           return true; // **** Always accept
       };

    username = PlayerPrefs.GetString("Identity");

    if (username == null || username == "")
    {
        username = Credentials.GetIdentityId();
        PlayerPrefs.SetString("Identity", username);
        PlayerPrefs.Save();
    }

    //Check if this user has any bots yet (if they do that we don't need to do the first time setup)
    string selectExpression = "Select count(*) From Bots where UserName = '" + username + "'";
    var selectRequestAction = new SelectRequest { SelectExpression = selectExpression };
    var selectResponse = SimpleDB.Select(selectRequestAction);

适用于iOS应用的AWS
