在 CakePHP 2.0 中加载供应商文件
我目前正在将我们的一个项目升级到 CakePHP 2.0.不幸的是，代码的第一行"出现了问题，我找不到解决该问题的方法.
I'm currently upgrading one of our projects to CakePHP 2.0. Unfortunately the "first line" of code makes problems, and I can't find a solution to that problem.
在 CakePHP 1.3 中，我在定义 AppController 类之前有一个 App::import("Vendor", "facebook"); 语句.引用的文件位于 /app/vendors/facebook/facebook.php 下(并包括 base_facebook.php 文件).
In CakePHP 1.3 I had an App::import("Vendor", "facebook"); statement right before the AppController class gets defined. The referenced file is located under /app/vendors/facebook/facebook.php (and includes itself the base_facebook.php file).
根据此处描述的文件命名和类加载，我尝试了许多不同的方法将文件包含在 CakePHP 2.0 中:CakePHP 2.0 文件命名和类加载变化
I tried many different ways to include the file now in CakePHP 2.0 according to the File naming and class loading described here: File naming and class loading changes in CakePHP 2.0
我将路径重命名为app/Vendor/Facebook/Facebook.php，或app/Vendor/Facebook/facebook.php，并尝试了以下方法:>
I renamed the path to app/Vendor/Facebook/Facebook.php, or app/Vendor/Facebook/facebook.php, and tried following methods:
App::uses("Facebook", "Vendor/Facebook");
App::uses("Facebook", "Facebook");
App::uses("Facebook", "Vendor/Facebook/Facebook.php");
App::uses("Facebook", "Vendor");
有没有人找到引用供应商文件的方法?由于延迟加载，上述方法不会触发错误/警告，因此调试它有点烦人......
Has anyone find a way to reference a vendor file yet? Because of the lazy loading the methods above do not fire an error/warning, so it's kind of annoying to debug this...
推荐答案
在 CakePHP 中无法使用 App::uses() 加载供应商，这是因为 CakePHP 不能期望外部库遵循相同有关文件夹和文件命名的标准.您仍然可以像在框架的 1.3 版中那样使用 App::import('Vendor', ...).
Vendors cannot be loaded using App::uses() in CakePHP, this is because CakePHP cannot expect external libraries to follow the same standards regarding folder and file naming. You can still use App::import('Vendor', ...) as you did in version 1.3 of the framework.
现在，如果您考虑一下，为供应商使用 App::import() 有点愚蠢.它只是 require_once() 的一个昂贵、冗长且非常愚蠢的包装器.
Now, using App::import() for vendors is kind of silly, if you think about it. It is just an expensive, verbose and very silly wrapper for require_once().
在 2.0 中，我们实际上鼓励人们为他们的供应商库使用 require 或 require_once.您可以使用 App::path('Vendor') 或仅使用 APP 来获取 Vendor 文件夹的位置.'小贩' .DS.
In 2.0, we actually encourage people to use require or require_once for their Vendor libraries. You can get the location of the Vendor folder using App::path('Vendor') or just APP . 'Vendor' . DS.
