Amazon SES SMTP 图像不显示
问题描述 投票：0回答：1
我疯狂地试图找出为什么图像没有显示在我的电子邮件中。正如您在下面看到的，仅显示了 Discord 徽标图像。
电子邮件是通过以下功能从我的 Java 游戏服务器发送的。亚马逊 SES SMTP。我尝试过对不同的字符进行编码，但没有成功。我将不胜感激任何帮助，因为我花了几个小时调整/测试这个。
public static void SendAmazonSESEmailPureJava(String TO, String CC, String BODY, String SUBJECT, int headerAndFooterCode){
new Thread(new Runnable() {
@Override
public void run() {
LOGGER.info("Attempting to send an email through Amazon SES by using plain Java...");
Transport transport = null;
try {
//Replace with your "From" address. This address must be verified.
final String FROM = "REDACTED";
String FROMNAME = "REDACTED";
String SMTP_USERNAME = "REDACTED";
//Replace smtp_password with your Amazon SES SMTP password.
String SMTP_PASSWORD = "REDACTED";
//Amazon SES SMTP host name. This example uses the US West (Oregon) region.
//See https://docs.aws.amazon.com/ses/latest/DeveloperGuide/regions.html#region-endpoints for more information.
String HOST = "email-smtp.us-east-1.amazonaws.com";
//The port you will connect to on the Amazon SES SMTP endpoint.
//This port is used by STARTTLS to encrypt the email
int PORT = 587;
//Create a Properties object to contain connection configuration information.
Properties props = System.getProperties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.port", PORT);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
//Create a Session object to represent a mail session with the specified properties.
Session session = Session.getDefaultInstance(props);

看起来这可能与 Google Image Proxy（即 googleusercontent）有关。托管图像的 Amazon S3 存储桶设置为可公开访问：
{
"Version": "2008-10-17",
"Statement": [
{
"Sid": "AllowPublicRead",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::kisnardonline.site/*"
}
]
}

似乎将 robots.txt 添加到我的存储桶的根目录解决了问题
