遇到"sh:php:找不到命令"在Lambda中运行os.system模块时出错 [英] encountered "sh: php: command not found" error while running os.system module in lambda

问题描述

我正在尝试使用python运行时在aws lambda中运行php脚本.我尝试使用python os.system模块调用php页面执行脚本.代码在下面给出

I'm trying to run a php script in aws lambda using python runtime. I tried using python os.system module to call the php page to execute the script. The code is given below

import os
def lambda_handler(event, context):
    os.system("php /home/admin/web/####/###.php")

在运行上述代码时，它显示错误:"sh:php:命令未找到".我对python脚本或shell脚本都不了解.因此，我们将不胜感激.

On running the above code, it displays error: "sh: php: command not found". I do not have much knowledge either in python scripting or shell scripting. So any help would be much appreciated.

更新:新代码

def lambda_handler(event, context):
    stream = os.popen("/usr/bin/php /home/admin/web/path/")
    output = stream.read()
    print(output) 

使用了新代码，但现在显示此错误:/bin/sh:/usr/bin/php74:没有这样的文件或目录.

Used the new code but its displaying this error now: /bin/sh: /usr/bin/php74: No such file or directory.

我不明白，因为php已安装到系统中，但它却表明不存在此类文件.

I don't understand, because php is installed into the system , but yet it is telling no such file exists.

推荐答案

您可以不在默认的 Python Lambda运行时中运行PHP脚本.没有安装PHP.

You can not run PHP scripts in the default Python Lambda runtime. There is no PHP installed.

因此，您有三个选择:

1. 将您的PHP代码迁移到Python.
2. 使用Python和PHP创建Docker映像并将其用作Lambda运行时.此功能是最近添加的，您可以在文档中的描述，创建自定义Lambda运行时.

您的原始问题包含PHP脚本，你想跑步.它只包含一个非常简单的MySQL查询.将那一行PHP代码迁移到Python应该很容易.

Your original question contained the PHP script, that you want to run. It only contained a very trivial MySQL query. It should be very easy to migrate that one line of PHP code to Python.

PHP代码:

<?php
$con1 = mysqli_connect("endpoint","###","###","database");
if(mysqli_query($con1,"insert into ex_inbox(time) values ('Done')") or die("the eror ".mysqli_error($con1)));
?>

因此，选项#1是我建议的选项.您可以阅读如何使用Python

Therefore, option #1 is the one I'd recommend. You can read how to do insert into a MySQL database using Python in this guide.
