訪問被拒絕到S3中的存儲桶-禁止錯誤403（精細上傳程序）

[英]Access denied to bucket in S3 - Error 403 Forbidden (Fine-Uploader)

 原文  2014-10-25 23:38:27  9   1    php/ amazon-s3/ fine-uploader

問題描述

我無法訪問Amazon S3中的存儲桶。 我按照官方博客中的Fineuploader（Fineuploader S3從您的瀏覽器直接上傳到Amazon S3）中的說明進行逐步操作，我檢查了類似的問題，但沒有一個參考此特定案例。

我的意圖是復制S3的fineuploader.com演示，唯一的不同是我沒有使用高級功能（分塊，拖放，重試等），換句話說，進行了“簡單上載”。

打擾一下，如果我很冗長或很露骨，我只想弄清楚我完成的程序。

我將代碼復制到了http://fineuploader.com/demos.html#amazon-demo的客戶端，並更改了以下幾行：

我在服務器端的代碼來自https://github.com/FineUploader/server-examples/blob/master/php/s3/s3demo-thumbnails-cors.php，僅注釋和更改了以下幾行。

評論行： 

// require 'aws-autoloader.php';
// use Aws\S3\S3Client;

// $serverPublicKey = $_SERVER['PARAM1'];
// $serverPrivateKey = $_SERVER['PARAM2'];

// $expectedMaxSize = 15000000;

更改的行： 

// Secret key - User create in IAM
$clientPrivateKey = $_SERVER['BIsYDPrOfWyWeUXueJaiaAem7he3R5THxx000Xxx'];
$expectedBucketName = "bucketname";

一切似乎都井井有條，但是當我上傳圖片時，我的Chrome控制台出現錯誤： 

POST http://bucketname.s3.amazonaws.com/ 403 (Forbidden)

訪問密鑰和秘密密鑰包含為說明目的而放置的字符X和0。 密鑰不是真實的。

感謝您的幫助。

$clientPrivateKey = $_SERVER['xxx'];

我認為這是錯誤的。 在原始文件中說： 

// These assume you have the associated AWS keys stored in
// the associated system environment variables
$clientPrivateKey = $_SERVER['AWS_SECRET_KEY'];

因此，要么在您的環境中設置一個名為AWS_SECRET_KEY的變量，然后將該行恢復為原來的狀態，要么只使用

$clientPrivateKey = 'xxx';

我還建議您更改密鑰，因為您現在已將其發布在公共場所，並且有人一定會在您的存儲桶中做討厭的事情！
