Question

我对我的问题感到非常生气。

我正在尝试做什么：

将“.flac”文件上传到我的服务器（可行）
使用àphp脚本启动àpython脚本（不起作用）
Python脚本调用google语音API将语音转换为文本（从终端直接启动时工作
在数据库中插入我的python处理结果（可行）

我尝试使用exec（）system（）和passthru（）命令。

我在互联网上搜索了很长时间才找到解决方案，而且我明确地阻止了我的php似乎没有等待我的python程序发生（在10秒到5分钟之间）。

当我尝试使用另一个只在数据库中插入值的python脚本时，一切正常，这让我真的假设我的php exec（）在结束之前杀死了我的python进程或类似的东西。所以我的代码如下。

PHP代码：

<?php
#Define target of uploaded file
$target_dir = "/var/www/voice/voice_file/";

#create unique new name for file
$var_name = md5(uniqid(rand(), true));

#define file extension for new file
$var_name .= ".flac";

#define (temporalily) comment value --> will be replaced by form "comment"
$commentaire = "\"test d'un commentaire\"";

# define target
$target_file = $target_dir . basename($var_name);


#moove flac file to target
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);


#execute python script to convert audio to text
ob_start();
passthru("python voice_file/convert_audio.py $target_file $commentaire");
$output = ob_get_clean();

?>

Python脚本。

我真的很感激一只手。非常感谢

php exec不适用于带有
