I am trying to send SNS messeges to android through web api. Downloaded and installed the SDK from http://aws.amazon.com/developers/getting-started/php/

运行 sample.php 时出现以下错误:

Got following error while running sample.php:

Fatal error: Uncaught exception 'AwsCommonExceptionInstanceProfileCredentialsException' with message 'Error retrieving credentials from the instance profile metadata server. When you are not running inside of Amazon EC2, you must provide your AWS access key ID and secret access key in the "key" and "secret" options when creating a client or provide an instantiated AwsCommonCredentialsCredentialsInterface object.

推荐答案

就我而言，我正在使用

return DynamoDbClient::factory(array(
  'version' => 'latest',
  'region'  => AWS_REGION,
  'key' => AWS_KEY,
  'secret'  => AWS_SECRET
));

过去用 aws/aws-sdk-php 版本 2.8.5 没问题，但是当 composer 自动安装版本 3.2.0 时，我得到了上面的错误.问题很简单，我应该改变我打电话给

which used to be ok with aws/aws-sdk-php version 2.8.5 , but when composer automatically installed version 3.2.0, I got the error above. The problem is simply that I should've changed the way I made the call to

return DynamoDbClient::factory(array(
  'version' => 'latest',
  'region'  => AWS_REGION,
  'credentials' => array(
    'key' => AWS_KEY,
    'secret'  => AWS_SECRET,
  )
));

如此处.在不更改调用的情况下，apache php 回退到使用空的 HOME 环境变量查找 ~/.aws/credentials 文件.您可以通过运行 php -r 'var_dump(getenv("HOME"));' 来检查它的值.

as documented here. Without changing the call, the apache php was falling back to looking for the ~/.aws/credentials file using the HOME environment variable, which was empty. You can check its value by running php -r 'var_dump(getenv("HOME"));'.
