java - Amazon Simple Email Service，凭证的范围应为正确的服务 : 'email'

Question

第一步，我在 Cognito

中创建了一个身份池。

启用对未经身份验证的身份的访问

添加了具有以下配置的未经身份验证的角色。

    {
     "Version": "2012-10-17",
     "Statement": [
     {
      "Effect": "Allow",
      "Action": [
        "cognito-sync:*",
        "ses:SendEmail"
      ],
      "Resource": [
        "*"
       ]
      }
     ]
    }

然后在 Android Studio 中，我为亚马逊添加了以下 SDK。

implementation 'com.amazonaws:aws-android-sdk-core:2.26.0'
implementation 'com.amazonaws:aws-android-sdk-cognito:2.20.1'
implementation 'com.amazonaws:aws-android-sdk-ses:2.20.1'

在我使用 cognito 初始化 Amazon SES 之后，如下所示:

     val credentials = CognitoCachingCredentialsProvider(
            context, // CONTEXT
            "us-east-1:your_identify_pool", // IDENTITY POOL ID
            Regions.US_EAST_1 // REGION
        )
        
        val ses = AmazonSimpleEmailServiceClient(credentials)
        ses?.setRegion(Region.getRegion(Regions.US_EAST_1))
        ses?.endpoint = "email.us-east-1.amazonaws.com"

接下来使用 SES 客户端发送电子邮件:

 val request = SendEmailRequest(email.from, destination, message)
 ses.sendEmail(request)

当我运行这个时，我得到了以下异常

com.amazonaws.AmazonServiceException: Credential should be scoped to 
correct service: 'email'. (Service: AmazonSimpleEmailService; Status 
Code: 403; Error Code: SignatureDoesNotMatch; Request ID: 5bd493a7-0184- 
49e6-bc03-5b95386d5b20)

Answer 1

我没有使用 cognito，而是使用了凭据，但它仍然无法正常工作，结果发现这是 sdk 的问题，尝试使用不同的 sdk 版本并找到了正确的组合。

implementation 'com.amazonaws:aws-android-sdk-core:2.26.0'
implementation 'com.amazonaws:aws-android-sdk-cognito:2.20.1'
implementation 'com.amazonaws:aws-android-sdk-ses:2.24.0'
