我cd进入所有pem/key文件所在的目录并运行以下命令:

aws iam upload-server-certificate 
    --server-certificate-name certificate_name 
    --certificate-body file://webservercertificate.pem  
    --private-key file://server.key   
    --certificate-chain file://certificate_chain_file.pem 

我收到以下错误:

调用UploadServerCertificate操作时发生客户端错误(InvalidClientTokenId):请求中包含的安全令牌无效.

我在"用户"中有1个"用户".该用户已被分配以下权限:

IAMFullAccess IAMReadOnlyAccess IAMUserSSHKeys

我已下载此用户的凭据并将其放入我的用户变量中

AWS_ACCESS_KEY ****
AWS_SECRET_KEY ****

我在弹性豆茎上有1个角色 aws-elasticbeanstalk-ec2-role

下午好,

让我们说我有一个矩阵.我有2个值,.9用于缩小,1.1用于放大.

当我申请matrix.postScale(0.9, 0.9);3次然后我申请matrix.postScale(1.1, 1.1);3次

我不回到我开始的地方!

例如,以下是我记录的结果:

当前比例postScale(x,x)结果比例

1                  .9               .9
.9                 .9               .80999994
.80999994          .9               .7189999

.7189999           1.1              .8018999
.8018999           1.1              .8820899
.8820899           1.1              .97029895

正如你所看到的,我不会回到1.发生了什么,我是否错误地获得了当前的比例？

例如,为了获得右边的所有值,我在应用postScale之后执行了此操作:

matrix.getValues(tempArrayFloat);
Number = tempArrayFloat[Matrix.MSCALE_X];

我只是假设MSCALE_X和MSCALE_Y会一样吗？

我的问题是,如果我使用1个特定值3次缩放矩阵,.9 - > .9 - > .9,我需要将它缩放回原始位置需要多少个数字？

-亲切的问候,

保罗

我有一个运行在弹性beanstalk EC2上的tomcat:
