Php Codeigniter中的S3上载错误

当我使用CI在s3中上载文件时，收到错误消息

消息：s3:：inputFile（）：无法打开输入文件：filename.jpg

这是我的密码

$time = Time();
if(!empty($_FILES['productImage']['name'])){
$file_name        =  $_FILES['productImage']['name'];
$productImageName = 'PRD_'.$time.$_FILES['productImage']['name'];
 if ($this->s3->putObjectFile($file_name, "bucketname", $productImageName, S3::ACL_PUBLIC_READ)) {
   echo "We successfully uploaded your file.";exit;
 }else{
    echo "Something went wrong while uploading your file... sorry.";exit;
 }
}

Hai我得到了另一个使用CI在s3中上传文件的解决方案。在这里我分享了代码。这将对将来的人有所帮助

来自github的代码：

我的代码是：

$this->load->library('aws_sdk');
try{
   $aws_object=$this->aws_sdk->saveObject(array(
   'Bucket'      => 'mybucket',
   'Key'         => 'QA/product/'.$newImagename,
   'ACL'         => 'public-read',
   'SourceFile'  => $_FILES['productImage']['tmp_name'],
   'ContentType' => 'image/jpeg'
))->toArray();

}catch (Exception $e){
  $error = "Something went wrong saving your file.\n".$e;
  echo $error;
}
