java - 使用java将对象放入S3但没有从控制台看到任何对象

Question

我尝试使用以下代码将字符串放入 S3 中。我看到该文件夹​​是在存储桶下创建的，但没有在该文件夹中看到任何对象。我错过了什么？

String SUFFIX = "/";

try 
{
    s3client.putObject(bucketName, today.toString() + SUFFIX + source + SUFFIX, "abc");
}
catch (Exception e) 
{
    e.printStackTrace();
}

我不认为这是一个权限问题，因为我有上面代码创建的那些文件夹，并且 try-catch 也没有捕获到异常。

请帮忙。谢谢

来自Amazon S3 folders documentation :

The Amazon S3 console treats all objects that have a forward slash (/) character as the last (trailing) character in the key name as a folder, for example examplekeyname/. You can't upload an object that has a key name with a trailing / character using the Amazon S3 console.

However, you can upload objects that are named with a trailing / with the Amazon S3 API by using the AWS CLI, AWS SDKs, or REST API.

An object that is named with a trailing "/" appears as a folder in the Amazon S3 console.

因此，在您的情况下，删除尾部斜杠应该可以完成工作:

String SUFFIX = "/";
try {
    s3client.putObject(bucketName, today.toString() + SUFFIX + source, "abc");
} catch (Exception e) {
    e.printStackTrace();
}
