这是我服务器上的php脚本。
<?php
$target_path1 = "/Pictures/"
$target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) {
echo "Success";
} else {
echo "fail";
}
?>

}
我正在将sourceUri传递给我的应用程序，例如/sdcard/pictures/temp.jpg
请帮助我，响应是HTTP Response 200，但服务器上没有文件。
使用XAMP phpmyadmin。

<强> PHP：
<?php
$target_path = "./uploads/";
$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!";
}
?>
有效！
