无法打开流：post 请求后执行 fopen 时权限被拒绝
我有 php 代码如下。
<?php
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "[HIDDEN]");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, array("code" => "print(1+1)"));
$result = curl_exec($curl);
echo $result;
?>
谁的帖子请求发送到...
<?php
if($_SERVER["REQUEST_METHOD"] == 'POST') {
$code = $_POST['code'];
$handle = fopen("canvas.py", "w");
fwrite($handle, $code);
$out = shell_exec("python canvas.py");
echo $out;
}
?>
我的目标是简单地将帖子请求发送到另一个 php 文件，发送帖子后，打开一个文件并将代码写入其中。然后，回显应该为 2 的输出。如果我的行话不正确，抱歉。
由于 fopen()，我不断收到错误“无法打开流：权限被拒绝”。我可以在同一个文件中使用 fopen，但是当第一个文件中的代码触发第二个文件时，我收到此错误。
它们位于同一目录中，我使用 chmod 777 {filename} 设置了每个文件的权限，包括 canvas.py 文件。最后，不确定这是否重要，但我正在不属于我的 Linux 服务器中使用“php file1.php”执行第一个代码。
I have php code as follows.
<?php
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "[HIDDEN]");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, array("code" => "print(1+1)"));
$result = curl_exec($curl);
echo $result;
?>
Whose post request goes to...
<?php
if($_SERVER["REQUEST_METHOD"] == 'POST') {
$code = $_POST['code'];
$handle = fopen("canvas.py", "w");
fwrite($handle, $code);
$out = shell_exec("python canvas.py");
echo $out;
}
?>
My goal here is to simply send a post request to another php file, with the post sent, open a file and write that code to it. Then, echo back the output which should be 2. Sorry if my jargon is incorrect.
I keep getting the error "Failed to open stream: Permission denied" because of fopen(). I can use fopen in the same file, but when the code from the first file triggers the second, I get this error.
They are in the same directory, I have set permissions of each file with chmod 777 {filename}, including the canvas.py file. Lastly, not sure if it matters but I am executing the first code with "php file1.php" in a linux server not owned by me.

发现了，只需更改Web服务器执行文件的权限即可。
Found it out, just had to change the permission of the web server to execute files.
