通过PHP将带有App Inventor 2的文件上传到服务器 [英] Upload a file with App Inventor 2 to a server through PHP

问题描述

我正在尝试使用PHP将带有App Inventor 2的文件上传到服务器.我遵循了照相亭Android应用教程，但是在服务器端，myPhoto.jpg包含文件名，而不包含图片内容(例如，myPhoto.jpg包含"file:///storage/emulated/0/Pictures/app_inventor_1424997354199.jpg"之类的内容).我该如何解决?

I am trying to upload a file with App Inventor 2 to a server through PHP. I followed the Photo Booth Android app tutorial, however server-side, myPhoto.jpg contains the filename, not the picture's content (e.g. myPhoto.jpg contains something like "file:///storage/emulated/0/Pictures/app_inventor_1424997354199.jpg"). How can I fix it?

我使用的代码:

tempSaveFile.php:

tempSaveFile.php :

<?php
 
$dataToWrite = $_REQUEST['fileName'];
$fileName = "myPhoto.jpg";     
file_put_contents($fileName, $dataToWrite);
 
?>

我知道 Taifun的教程，但是由于在我的php.ini always_populate_raw_post_data = On中，我更喜欢避免必须安装任何东西.

I am aware of Taifun's tutorial but since in my php.ini always_populate_raw_post_data = On I would prefer to avoid having to install anything.

斯科特的教程似乎做类似的事情(使用App Inventor 1):

Scott's tutorial seems to do something similar (with App Inventor 1):

推荐答案

，您应该只传输没有路径的文件名，例如app_inventor_1424997354199.jpg

in the URL you should only transfer the filename without path, e.g. app_inventor_1424997354199.jpg

中，您应使用完整路径，例如file:///storage/emulated/0/Pictures/app_inventor_1424997354199.jpg

in the PostFile block you should use the complete path, e.g. file:///storage/emulated/0/Pictures/app_inventor_1424997354199.jpg

然后在服务器上，尝试Scott的解决方案

then on the server, try Scott's solution

<?PHP
   $data = file_get_contents('php://input');
   if (!(file_put_contents($_GET['fileName'],$data) === FALSE)) echo "File xfer completed."; // file could be empty, though
   else echo "File xfer failed.";
?>
