如何將縮略圖文件上傳到亞馬遜s3存儲桶？

嗨，我是亞馬遜的新手，對文件的處理方法很少。我試圖將縮略圖上傳到存儲區中。我可以上傳本地主機中的一個圖像，但我不能把它上傳在bucket.I可以在原始圖像上傳到桶中，這裏是我的代碼如何將縮略圖文件上傳到亞馬遜s3存儲桶？

我的原始文件上傳成功，但我收到以下錯誤在上傳縮略圖時，

有人可以幫我嗎？在此先感謝...

我得到這個錯誤使用$ this，而不是在/ Applications /在線74上的XAMPP/xamppfiles/htdocs/image_thumbnail_creation_php/index.php @kelvin kantaria – Anu

我解決了這個錯誤。我在類文件中使用api比我使用$ this。你刪除$這也包括S3類文件 –

它的工作...驚人謝謝@kelvin kantaria – Anu

嘗試此設置正確的路徑在哪裏上傳縮略圖在您的服務器根目錄。

$upload_img = Upload('image','uploads/','',TRUE,'uploads/thumbs/','200','160'); 
    $upload_img1 = Upload('image','products/','',TRUE,'products/','200','160'); 
    // Absoulte path where to upload thumnail 
    //$fileTempName12 = $_FILES[$upload_img1]['tmp_name']; comment this line 
    //$fileName12 = 'products/'.$_FILES[$upload_img1]['name']; 
    //full path of the thumbnail image 
    $thumb_src = 'products/'.$upload_img1; 
    $s3->putBucket("bucketname", S3::ACL_PUBLIC_READ); 

    if ($s3->putObjectFile($upload_img1, "bucketname", $thumb_src, S3::ACL_PUBLIC_READ)) { 
     echo "<strong>We successfully uploaded your file.</strong>"; 
    }else{ 
     echo "<strong>Something went wrong while uploading your file... sorry.</strong>"; 
    }

我嘗試這樣做收到此錯誤注意：未定義的變量：putObjectFile在/Applications/XAMPP/xamppfiles/htdocs/image_thumbnail_creation_php/S3.php上第187行 – Anu

thumnail在s3存儲區中上傳了哪些內容？請分享S3.php文件代碼。 – user5200704

我已經包含在問題中，請參考它。 @ user5200704 – Anu
