图像下载，而不是显示在浏览器中使用amazon s3 - Codeigniter - Image downloading instead of displaying in browser using amazon s3 - Codeigniter

Image downloading instead of displaying in browser using amazon s3 - Codeigniter

我正在尝试上传图片到Amazon S3，当我通过表单提交时，它会上传成功，但是当我点击图片的url时，它会下载图像而不是在浏览器中显示图像，请检查我的代码，我等待您的回复。

if ($s3->putObjectFile($fileTempName, "bucket/images", $fileName, 
S3::ACL_PUBLIC_READ)) {
echo "We successfully uploaded your file.";
}else{
echo "Something went wrong while uploading your file... sorry.";
}
// Get the contents of our bucket
$url = "http://bucket.s3.amazonaws.com/images/".$fileName;
printf($url);
exit();

我自己跟踪，最后我解决了这个问题。简单地说，我们需要在putObjectFile()参数中添加[array $metaHeaders = array()]， [string $contentType = null]，通过此图像将在浏览器中打开而不是下载。因此，现在我更改了代码:

$fileName       =   $_FILES['file']['name'];
$fileTempName   =   $_FILES['file']['tmp_name'];
$contentType    =   $_FILES['file']['type']; 
$metaHeaders = array();
if($s3->putObjectFile($file, "bucket", $filename, S3::ACL_PUBLIC_READ, $metaHeaders, $contentType)){
echo "We successfully uploaded your file.";
                }
else{
                 echo "Something went wrong while uploading your file... sorry.";
                }

所以，它工作得非常好。

谢谢

代替printf($url); try this

echo "<a href='$url'>$url</a>";

我为我的桶使用了以下代码。如果它适合你，试试吧。

<?php $client = 'Aws'S3'S3Client::factory(array(
        'key' => 'XXXXXXXXXXXXXXXX',
        'secret' => 'XXXXXXXXXXXXXXXXXXXXXXXXX',
        'region' => 'XXXXXXXXXXXXXXXXX',
    ));
function getDocFromS3($file, $doc_type){
    global $client;
    $bucket_dir = getBucketName($doc_type);
    /*$result = $client->getObject(array(
            'Bucket' => $bucket_dir,
            'Key'    => $file
    ));*/
    $file = "{$bucket_dir}/{$file}";
    $result = $client->get($file);
    $url = $result->getURL();
    return $url;
}
function getBucketName($doc_type){
    if(DEV || LCD){
        $bucket_name = 'public-estify-dev';
    } else {
        $bucket_name = 'public-estify';
    }
    return $bucket_name.'/evm/docs/'.$doc_type;
} ?>
