Question

我正在尝试创建一个简单的网页，该网页执行位于我的主目录中的单独python脚本。由于该脚本包含通过raspberry pi扬声器启动天气预报和新闻报道的命令，因此网页上无需打印任何内容。

我搜索了高低，但只能找到在页面上打印系统信息的方法。如果可能的话，我希望在网页上添加一个按钮（index.php），按下该按钮将激活下面显示的脚本。谢谢！

尝试使用代码

创建index.php

<html>
<body>
    <a href="runscript.php">Run script.</a>
</body>
</html>

和带有

的runscript.php

<html>
<body>
    Starting script.
    <?php
        shell_exec('touch /tmp/foo.txt');
    ?>
</body>
</html>

结果：在/ tmp文件夹中成功创建了foo.txt。

但是，当我尝试将命令更改为sudo python /home/pi/alarm.py时，脚本未执行。我也尝试将index.php改为

<form action="alarm.py">
    <input type = "submit" value = "submit" name ="load">
</form>

但是当按下按钮（提交）时，网页显示内部服务器错误。

Answer 1

您只需创建一个表单（甚至是一个链接），该表单将指向一个PHP页面，该页面将服务器上的脚本排除在外。

对于PHP部分，请查看this关于执行外部程序的php手册，找出最适合您需求的程序。它可能还取决于您的平台/环境。

对于Linux，您可以使用类似

的内容

$output = shell_exec('python /path/to/your/script.py');

如果您不需要脚本的文字输出，则可以省略$output =内容。

完整的包可能如下所示：

包含链接的页面

<html>
<body>
    <a href="runscript.php">Run script.</a>
</body>
</html>

<强> runscript.php

<html>
<body>
    Starting script.
    <?php
        shell_exec('pyhton /path/to/your/script.py');
    ?>
</body>
</html>

Answer 2

在index.php

中添加以下代码

<form action="[your script name]">
    <input type = "submit" value = "submit" name ="load">
</form>

打开网页时在后台执行python脚本（不打印脚本）
