擴展Laravel包

Question

我周圍中搜索，找不到這一個明確的答案......

我有一個包DevDojo顫振，並想用我的應用程序來擴展它。我知道我必須重寫這些函數，以便作曲家更新不會覆蓋我的更改。

我該如何去做這件事？

UPDATE

public function store(Request $request) 
{ 
    $request->request->add(['body_content' => strip_tags($request->body)]); 

    $validator = Validator::make($request->all(), [ 
     'title'    => 'required|min:5|max:255',

有，我想修改/替代供應商包內的存儲功能。如果需要，我希望能夠修改某些功能或其中的一部分。請有人指出我正確的方向。

如果你的意思修改類實現您的應用程序，你可以改變的方式類解決：

app()->bind(PackageClass:class, YourCustomClass::class); 

，現在你可以創建這個自定義類，像這樣：

class YourCustomClass extends PackageClass 
{ 
    public function packageClassYouWantToChange() 
    { 
     // here you can modify behavior 
    } 
} 

我會建議你可以閱讀更多關於binding。

當然很多依賴於如何創建類，如果它是使用new運算符創建的，您可能需要更改多個類，但是如果它被注入，它應該足以改變這個類。
