Question

我目前正在Laravel创建一个博客来学习PHP / Laravel。问题是我得到了：

RouteCollection.php第218行中的MethodNotAllowedHttpException：

我有一张桌子，我用按钮显示所有帖子＆＃34; View＆＃34;和＆＃34;编辑＆＃34;每个帖子。他们使用id重定向到相关视图，并且工作正常。当我打开任何帖子查看时，还有一个用于编辑的按钮，这是我点击它时我得到错误的地方，我不知道为什么。

show.blade.php //这是＆＃34;查看＆＃34;对于帖子

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

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

    <div class="col-md-4">

Answer 1

那是因为您使用的表单已将方法定义为POST，但路由定义为GET：

将其更改为：

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

此外，您可以使用链接而不是表单：

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

当我点击按钮重定向到另一个视图时，MethodNotAllowedException
