Question

안드로이드 폰에서 PHP 서버로 img를 업로드하려고합니다. 이

을 손실 데이터 업로드 (파일이 존재를하지만, 0 바이트를 가지고) 때

는하지만 문제가 PHP 측 또는 안드로이드 측에 있는지 잘 모릅니다. 여기

내가 업로드 사용하는 코드입니다

PHP :

<?php 
$base=$_REQUEST['image']; 
$binary=base64_decode($base); 
header('Content-Type: bitmap; charset=utf-8'); 
$file = fopen('uploaded_image.jpg', 'wb'); 
fwrite($file, $binary); 
fclose($file); 
echo 'Image upload complete!!, Please check your php file directory……'; 
?>

해결책 :

<?php 
$target_path = "./"; 
$target_path = $target_path . basename($_FILES['uploadedfile']['name']); 
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { 
echo "The file ". basename($_FILES['uploadedfile']['name']). 
" has been uploaded"; 
} else{ 
echo "There was an error uploading the file, please try again!"; 
} 
?>

Answer 3

PHP 업로드를 사용해야합니까? 나는 항상 FTP 업로드 (백엔드가 FileZilla를 사용할 수 있음)를보다 쉽게 ​​구현하고 더 안정적이라고 생각합니다!
