SignatureDoesNotMatch，我们计算的请求签名与您提供的签名不匹配

Question

我查看了关于 SO 的其他问题，他们都没有将 SES 和 Java 作为他们问题的一部分。

例外

        ListVerifiedEmailAddressesResult verifiedEmails = ses
                .listVerifiedEmailAddresses();
        if (verifiedEmails.getVerifiedEmailAddresses().contains(address))
            return;

        ses.verifyEmailAddress(new VerifyEmailAddressRequest()
                .withEmailAddress(address));
        System.out.println("Please check the email address " + address
                + " to verify it");
        System.exit(0);
    }
}

SES 设置

1. 将 myproductdomain.com 添加到域。
2. 将 admin@myproductdomain.com 添加到电子邮件地址。

AwsCredentials.properties

1. 对于 secretKey="aws 网站登录密码"
2. 对于 accesskey="https://console.aws.amazon.com/iam/home#users，安全凭证，对于 ses-smtp-user.some_number，访问密钥"

我正在从 Eclipse 插件中尝试 SES 的“hello world”。应该开箱即用。

Answer 1

我认为问题在于您使用的是“ses-smtp-user.some_number”。 您会看到，使用 SES，有两种发送电子邮件的方式。

• 使用网络服务 (AmazonSimpleEmailServiceClient)
• 使用 SMTP

为 smtp 创建的用户是 ses-smtp-user.some_number。 您正在使用该凭据进行 Web 服务调用。

我的建议是创建一个普通用户（不是从 SES 屏幕），并分配 SES 权限。 请注意，新创建的凭据现在不适用于 SMTP。

如果您想要一个同时适用于 SMTP 和 Web 服务的凭据，您可能需要阅读以下内容：http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html#smtp-credentials-convert
