基本上，我想解决此错误
缺少[Route：post.show] [URI：post / show / {id}]所需的参数。 （查看：C：\ xampp2 \ htdocs \ galaxall \ resources \ views \ index.blade.php）
我正在尝试在我的网站上建立一个系统，以便用户可以发布，查看帖子的评论并进行回复。
当用户在http://localhost:8000/post/create中键入其帖子的详细信息时，应该接受这些值，将其插入数据库中并重定向到http://localhost:8000/posts/show，并显示曾经“已发布”的帖子列表这样用户可以查看帖子可以发表评论并回复关于该帖子的评论。
但是
当前发生的情况是在输入要发布的详细信息后
http://localhost:8000/post/create，它会插入db，然后在laravel“自定义”错误页面上显示此错误：
缺少[Route：post.show] [URI：post / show / {id}]所需的参数。 （查看：C：\ xampp2 \ htdocs \ galaxall \ resources \ views \ index.blade.php）
我不知道我在做什么错。
请帮助

答案 0 :(得分：0)
route函数的第二个参数应该是参数名称到值对的数组，例如
<a href="{{ route('post.show', ['id' => $post]) }}" class="btn btn-primary">
Show Post
</a>
