Question

我无法从我的应用访问我的aws S3服务器存储桶。我在存储桶日志文件中收到请求，但访问被拒绝。我有内联策略和托管策略允许完全访问服务器，以及设置服务器权限以允许每个人，但它仍然说访问被拒绝。也创建了右池的标识。在应用程序结束时，我收到一条消息，表明找不到存储桶。服务器区域是伦敦。

我已经阅读了很多关于这个问题的其他问题，但没有一个能解决我的问题。

谢谢

内联未经身份验证的IAM政策

        "Action": [
            "s3:*"
        ],
        "Resource": [
            "arn:aws:s3:::ascentserver/*"
        ]
    }
]

}

由于某些原因，这在策略模拟器上不起作用，我尝试为存储桶和服务添加资源，但没有帮助。

托管策略是默认的S3完全访问权限，并模拟为正常工作。

  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "*"
    }
  ]
}

寻址服务器的代码段：

public void setFileToUpload(){

       TransferObserver transferObserver = transferUtility.upload(
                "http://ascentserver.s3.eu-west-2.amazonaws.com",     /* The bucket to upload to */
                "TEST.png",    /* The key for the uploaded object */
                fileToUpload       /* The file where the data to upload exists */
        );

       transferObserverListener(transferObserver);
    }

Answer 2

您需要为function myonEdit(){ var ss = SpreadsheetApp.getActiveSheet(); var e = ss.getActiveCell(); var heading = ss.getRange(1, e.getColumn()).getValues(); var rvalue = e.getValue(); var email_finished = "abc@xyz.com"; var ui = SpreadsheetApp.getUi() ui.alert("Are you sure?", ui.ButtonSet.OK) if (heading == "FINISHED" && rvalue == "√") { MailApp.sendEmail(email_finished, "SOP Review", "SOP has been finished"); } }方法提供ascentserver而不是http://ascentserver.s3.eu-west-2.amazonaws.com的存储分区名称，并确保transferUtility.upload()使用正确的区域而不是默认区域将端点设置为AmazonS3Client。

例如：

s3.setEndpoint("s3.eu-west-2.amazonaws.com")
