MethodNotAllowedException當我點擊按鈕重定向到另一個視圖

Question

我目前在Laravel創建一個博客學習PHP/Laravel。問題是，即時得到：

MethodNotAllowedHttpException在RouteCollection.php行218：

我有一個表，其中i顯示了所有按鈕「查看」每個職位的崗位和「編輯」。他們重定向到與id相關的觀點，他們工作得很好。當我打開任何帖子查看有一個編輯按鈕，這是我得到錯誤，當我點擊它，我不知道爲什麼。

show.blade.php //這是在 「視圖」 後

<div class="row"> 
    <div class="col-md-8"> 
     <h1>{{ $post->title }}</h1> 

     <p class="lead">{{ $post->body }}</p> 
    </div> 

    <div class="col-md-4"> 
     <div class="well"> 
      <dl class="dl-horizontal"> 
       <dt>Created at:</dt> 
       <dd>{{ date('d M, y H:i', strtotime($post->created_at)) }}</dd> 
      </dl> 
      <dl class="dl-horizontal"> 
       <dt>Last Updated:</dt> 
       <dd>{{ date('d M, y H:i', strtotime($post->updated_at)) }}</dd> 
      </dl> 
      <hr> 
      <div class="row"> 
       <div class="col-sm-6"> 
        <form method="POST" action="{{ route('posts.edit', $post->id) }}">

    Session::flash('success', 'The blog post was successfully saved!');

public function update(Request $request, $id)

} 

public function destroy($id)

} 

Answer 1

那是因爲你正在使用已定義的方法爲POST但路線被定義爲GET形式：

將其更改爲：

<form method="GET" action="{{ route('posts.edit', $post->id) }}"> 
    <input type="submit" value="Edit" class="btn btn-danger btn-block"> 
</form> 

此外，您還可以使用一個鏈接，而不是形式：

<a href="{{ route('posts.edit', $post->id) }}" class="btn btn-danger btn-block">Edit</a>
