Ios AWS S3桶问题

有人能帮我找到如何使用客户端

访问密钥ID

和

秘密访问密钥

访问AWS S3 Bucket资源吗？

---

或者这是不推荐使用的AWS API？我找到了很多解决方案，但都使用了我不想使用的

identityPoolId

。

您可以使用两种方式登录。

通过在代码中使用凭据

将您的凭据保存在一个文件中

通过在代码中使用凭据。 将您的凭据保存在一个文件中： 对于crud操作，您可以阅读本教程： 有关在特定存储桶中授予权限的信息，请查看图片：

添加权限：

{
    "Version": "2008-10-17",
    "Statement": [
        {
            "Sid": "AllowPublicRead",
            "Effect": "Allow",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::riz-bucket001/*"
        }
    ]
}

N.B：此桶策略使桶中的所有内容都公开可读。所以要小心使用它。如果你用学习的目的，那么好。但出于商业目的，不要使用它。

非常感谢

您所说的存储桶资源是什么意思？举个例子。你可能想考虑使用。它为Amazon S3提供了特定的命令。哇——这里有一个潜在的危险建议——bucket策略使bucket中的所有内容都可以公开阅读。@Michael sqlbot感谢您的指点。我已经更新了ans，并告知您只能将其用于学习目的，而不能用于商业目的。
