Question

首先，我没有使用php的经验。

我安装了维基媒体软件，以便将wiki文本标记字符串解析为html。因此，我设置了一个Apache服务器（localhost），我正在使用Pyhton中的api.php解析wiki文本（请求库）。

一切正常，但问题是我会使用RPC做同样的事情，换句话说，从命令行调用api.php脚本。

发送请求时，查询为：

http://localhost/mediawiki-1.22.5/api.php?action=parse&text=ABC&format=xml&disablepp=1

此查询解析ABC文本。

我会从命令行做同样的事情，我尝试了不同的东西，比如：

$shell>php api.php ?action=parse&text=ABC&format=xml&disablepp=1
or
$shell>php api.php action=parse&text=ABC&format=xml&disablepp=1
...

我试图从命令行调用的原因是，因为我在本地运行服务器，所以直接执行脚本会使事情变得更快，除了我可以透明地使用其他PHP引擎，如Facebook HipHop我的意思是，无需配置Web服务器。

也许最好的解决方案应该是在php中编写一个简单的包装器脚本，它在内部调用api.php并将命令args转换为“url gets”。不幸的是，由于我是PHP的完全门外汉，我不知道如何编码。

这里有任何帮助吗？

P.S：在php.api源代码下面：

<?php
/**
 * This file is the entry point for all API queries.
 *
 * It begins by checking whether the API is enabled on this wiki; if not,
 * it informs the user that s/he should set $wgEnableAPI to true and exits.
 * Otherwise, it constructs a new ApiMain using the parameter passed to it
 * as an argument in the URL ('?action=') and with write-enabled set to the
 * value of $wgEnableWriteAPI as specified in LocalSettings.php.
 * It then invokes "execute()" on the ApiMain object instance, which
 * produces output in the format specified in the URL.

执行此操作的常规方法是通过本地服务器调用API。这就是它的工作方式。

如你所说，编写一个“简单的包装器脚本”来从命令行提供API将是很多的工作。正如您在源代码中看到的那样，php.api从title.php调用Title class，而这反过来调用了其他PHP文件中的10个左右的其他类，反过来......，好吧，你明白了。

它也可能不会有任何性能优势（例如How to avoid network call when REST client and server are on the same server）。维持这将是一场噩梦。

如果您决定构建API的某些命令行实现，请查看maintenance class（旨在编写命令行MediaWiki维护脚本）和FauxRequest class （用于在API内部发出“假”请求）。
