上传文件用PHP

Question

s3的我用PHP上传文件在S3中，我的代码正常工作然而，当文件选择上传是非常重样4 MB操作失败，我有这样的错误：

NoSuchKey的指定的键不exist.1469625998.pdf136D99DB27E5B57FE6UXAbj45afkoAlfysDm2 + EPhBqHOhwc64gaG1w/b1AXAsfhnF7qwlankwuflh + ZO1sf/JBe6tA =

但是，当文件大小约为1.3 MB，上传成功。下面 是我的代码：

$name = $_FILES['file']['name']; 
$tmp = $_FILES['file']['tmp_name']; 
include('s3folder/s3_config.php'); 
$s3->putObjectFile($tmp, $bucket , $name, S3::ACL_PUBLIC_READ); 

我不知道为什么文件的任何规模大小无法上传，因为我不指定一个像任何大小的文件，如果（$大小<（1024 * 1024）） ！

下载脚本here包含4个文件

• S3.php // Amazon S3的库文件
• s3_config.php //重点配置文件
• image_check.php //文件校验
• index.php

s3_config.php

<?php 
// Bucket Name 
$bucket="BucketName"; 
if (!class_exists('S3'))require_once('S3.php'); 

//AWS access info 
if (!defined('awsAccessKey')) define('awsAccessKey', 'ACCESS_KEY'); 
if (!defined('awsSecretKey')) define('awsSecretKey', 'ACCESS_Secret_KEY'); 

$s3 = new S3(awsAccessKey, awsSecretKey); 
$s3->putBucket($bucket, S3::ACL_PUBLIC_READ); 
?> 

的index.php 该文件包含PHP和HTML代码提交表单。

<?php 
include('image_check.php'); // getExtension Method 
$msg=''; 
if($_SERVER['REQUEST_METHOD'] == "POST") 
{ 
$name = $_FILES['file']['name']; 
$size = $_FILES['file']['size']; 
$tmp = $_FILES['file']['tmp_name']; 
$ext = getExtension($name); 

if(strlen($name) > 0) 
{ 
// File format validation 
if(in_array($ext,$valid_formats)) 
{ 
// File size validation 
if($size<(1024*1024)) 
{ 
include('s3_config.php'); 
//Rename image name. 
$actual_image_name = time().".".$ext; 

if($s3->putObjectFile($tmp, $bucket , $actual_image_name,   S3::ACL_PUBLIC_READ)) 
{ 
$msg = "S3 Upload Successful."; 
$s3file='http://'.$bucket.'.s3.amazonaws.com/'.$actual_image_name; 
echo "<img src='$s3file'/>"; 
echo 'S3 File URL:'.$s3file; 
} 
else 
$msg = "S3 Upload Fail."; 

} 
else 
$msg = "Image size Max 1 MB"; 

} 
else 
$msg = "Invalid file, please upload image file."; 

} 
else 
$msg = "Please select image file."; 

} 
?> 

//HTML Code 
<form action="" method='post' enctype="multipart/form-data"> 
Upload image file here 
<input type='file' name='file'/> <input type='submit' value='Upload Image'/> 
<?php echo $msg; ?> 
</form> 

创建一个桶，然后右击选择属性，添加许可选择Everyone使检查列表框中。

image_check.php 此文件帮助您获取文件扩展名。

<?php 
function getExtension($str) 
{ 
$i = strrpos($str,"."); 
if (!$i) { return ""; } 
$l = strlen($str) - $i; 
$ext = substr($str,$i+1,$l); 
return $ext; 
} 
//Here you can add valid file extensions. 
$valid_formats = array("jpg", "png", "gif","bmp","jpeg","PNG","JPG","JPEG","GIF","BMP"); 
?>
