macOS Sierra的更改可防止“说".在PHP脚本中执行 [英] A change in macOS Sierra prevents "say" to be exec'd in a PHP script

问题描述

我有一台有一个小站点的macOS服务器，该站点可以使用say命令将文本片段转换为音频.

I have a macOS server with a little site which converts text snippets to audio using say command.

通过升级到Sierra，除了一件事情，一切都进行得很顺利:say命令在用我的PHP脚本包裹在exec()中后不再起作用.

With upgrade to Sierra, everything went smooth except one thing: the say command doesn't work any more when wrapped in exec() in my PHP script.

页面刚刚超时.也没有发现错误.

The page just times out. No error is caught either.

<?php
    try {
        exec('/usr/bin/say "hello"');
    }
    catch (Exception $e) { echo $e->getMessage(); }
?>

通常，我会用say -o filename保存音频片段，但是我尝试了所有变体以及其他运行良好的shell命令，包括在我的输出文件夹中创建文件.

Typically I would save the audio snippets with say -o filename but I tried all the variants and also other shell commands which worked fine including creating files in my output folder.

有趣的是，如果我从命令行运行它，它会起作用-大声说出来或创建一个输出文件.

Interesting is that if I run it from a command line, it works - either says it loud or creates an output file.

macOS Sierra具有PHP 5.6.24，所以我认为safe_mode不适用，对吗?

macOS Sierra has PHP 5.6.24 so I don't think safe_mode applies, righht?

我想强调指出，在新操作系统中，PHP或say命令的更改是最近的.是的，我确实调查过并尝试了不同的输出和stderr重定向，但是脚本只是挂起了.

I would like to emphasise that the change in either PHP or say command was quite recent, with the new OS. Yes I did look into and tried different output and stderr redirection but the script just hangs.

在Activity Viewer(等效于top的GUI)中看到say命令，我尝试对其进行采样，不确定是否有帮助:

Seeing the say command in Activity Viewer (GUI for top equivalent), I tried to sample it, not sure if it helps:

这些是统计数据:

从打开的文件和端口中，我可以看到我将stdout和stderr都设置为/private/var/log/apache2/error_log，但那里什么也没有显示.

And from open files and ports, I could see that I set both stdout and stderr to /private/var/log/apache2/error_log yet nothing shows there at all.

此外，尝试捕获运行更复杂的输出，但是没有乐趣，只是超时(脚本文件夹也是可写的):

Also, tried to capture outputs with more elaborate run, but no joy, just timeout (the script folder is also writable):

<?php   
    try {
        $pipes = array();
        proc_close(proc_open("say hi", array(0 => array("pipe", "r"), 1 => array("pipe", "r"), 2 => array("pipe", "r")), $pipes, dirname(__FILE__), null));
    } catch (Exception $e) { error_log($e->getMessage()); }
?>

更新:High Sierra相同.

UPDATE: High Sierra is the same.

最终更新:安装Mojave(删除了大部分Server.app功能)后，我添加了MAMP来处理此任务. 如果您愿意，可以自己听-位于 macspeaks.com .

FINAL UPDATE: after installing Mojave, which removes most of the Server.app features, I added MAMP to handle this task. Hear it for yourselves if you wish - it's at macspeaks.com.

故事继续:在安装Catalina期间，还是以某种方式更新了MAMP? (现在是5.5版)，我再次杀死了它. igh ...

THE STORY CONTINUES: somehow during the install of Catalina, or was it MAMP update? (now on 5.5), I killed it again. Sigh...

推荐答案

在Jenkins作业上使用say命令时，我遇到了同样的问题.我的Jenkins服务器在macOS Sierra上充当守护程序.

I have experienced same problem while using say command on my Jenkins job. My Jenkins server is working as daemon on macOS Sierra.

在我的情况下，我这样解决了这个问题:

In my case I solved this problem like this:

1. 以jenkins用户身份登录，并使用ssh-keygen生成ssh密钥.

2. 在.ssh/authorized-keys后面附加~/.ssh/id_rsa.pub，这样就不会要求输入密码.

1. Login as jenkins user and generate ssh key with ssh-keygen.

2. Append ~/.ssh/id_rsa.pub to .ssh/authorized-keys so that password will not be requested.

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized-keys

更改我的Jenkins作业，该作业使用say命令，如下所示:

Change my Jenkins job which use say command like this:

ssh localhost say -v Alex "Test"

对不起，我尚未使用Apache/PHP进行过测试，但是为什么不这样尝试呢?

I’m sorry, I have not tested with Apache/PHP, but why don't you try this way like this:

<?php
    try {
        exec('/usr/bin/ssh localhost /usr/bin/say "hello"');
    }
    catch (Exception $e) { echo $e->getMessage(); }
?>
