使用Amazon S3的PHP SDK的錯誤

Question

編輯：問題已解決（感謝this post）！我只是需要捲曲安裝：

sudo apt-get install php5-curl 

---

我一個工具的工作從瀏覽器上傳的AWS S3存儲桶的圖像。我正在使用亞馬遜提供的PHP SDK。 我試圖在documentation提供的代碼，但它不和我一起工作：即使我只保留這兩條線

use Aws\S3\S3Client; 

$bucket = '*** Your Bucket Name ***'; 
$keyname = '*** Your Object Key ***'; 
// $filepath should be absolute path to a file on disk      
$filepath = '*** Your File Path ***'; 

// Instantiate the client. 
$s3 = S3Client::factory(); 

// Upload a file. 
$result = $s3->putObject(array(
    'Bucket'  => $bucket, 
    'Key'   => $keyname, 
    'SourceFile' => $filepath, 
    'ContentType' => 'text/plain', 
    'ACL'   => 'public-read', 
    'StorageClass' => 'REDUCED_REDUNDANCY', 
    'Metadata'  => array( 
     'param1' => 'value 1', 
     'param2' => 'value 2' 
    ) 
)); 

echo $result['ObjectURL']; 

：

use Aws\S3\S3Client; 
$s3 = S3Client::factory(); 

...我得到這些錯誤：

剛安裝AWS PHP SDK我的本地機器上，無需任何註冊AWS， 幾經改掉了這個工作代碼：

use Aws\S3\S3Client; 

$bucket = '*** Your Bucket Name ***'; 
$keyname = '*** Your Object Key ***'; 
// $filepath should be absolute path to a file on disk      
$filepath = '*** Your File Path ***'; 

// Instantiate the client. 
$s3 = S3Client::factory(); 
try{ 

// Upload a file. 
$result = $s3->putObject(array(
    'Bucket'  => $bucket, 
    'Key'   => $keyname, 
    'SourceFile' => $filepath, 
    'ContentType' => 'text/plain', 
    'ACL'   => 'public-read', 
    'StorageClass' => 'REDUCED_REDUNDANCY', 
    'Metadata'  => array( 
     'param1' => 'value 1', 
     'param2' => 'value 2' 
    ) 
)); 
echo $result['ObjectURL']; 

} catch (Exception $e) { 
    echo $e->getMessage() . "\n"; 
} 

此代碼返回AWS異常消息：

您必須指定機構或參數的SourceFile一個非空值。

，如果我改變$filepath的路徑任何真正的文件，該代碼輸出：

錯誤檢索憑證從實例配置文件元數據服務器。當您不在Amazon EC2內部運行時，創建客戶端或提供實例化的Aws \ Common \ Credentials \ CredentialsInterface對象時，必須在「密鑰」和「祕密」選項中提供AWS訪問密鑰ID和祕密訪問密鑰。 （[捲曲] 28：5000毫秒後連接超時[url] http://XXX.xxx.xxx.xxx/latest/meta-data/iam/security-credentials/）

所以，如果有任何問題，你是非常歡迎，但它必須工作。

順便說一句，如果我從代碼中刪除catch部分我從我的破碎的頁面上從PHP獲取相同的錯誤消息。

希望這可以幫助你在你的情況。
