laravel-5.8：：此路由不支持POST方法。支持的方法: GET，HEAD

Question

您好，我正在尝试更新数据，但它显示错误“此路由不支持POST方法。支持的方法: GET，HEAD。”

路由：

Route::prefix('admin')->namespace('Admin')->name('admin.')->group(function () {
    Route::resource('category','CategoryController'); 
});

控制器：

public function edit(Category $category) 
{
    $categories = Category::findOrFail($category->id); 

    return view('admin.category.edit', compact('categories')); 
} 

public function update(Request $request, Category $category)
{
    $request->validate([
        'category_name'         => 'required|unique:categories',
        'category_description'  => 'required',
        'category_slug'         => 'required',
        'category_image'        => 'required|image',
    ]);

    $category = Category::find($category->id);
    $category->category_name = $request->category_name;
    $category->category_description = $request->category_description;
    $category->category_slug = $request->category_slug;
    $path = $request->file('category_image');
    $image = $path->getClientOriginalName();
    $path->move(public_path('images/backend_images/category_images'), $image);
    $category->category_image = $image;
    $category->save();

    return redirect('admin.category.index')->back()->with('flash_message_success', 'Category has been updated successfully');

刀片文件：

<form method="POST" action="{{ route('admin.category.update', $category->id) }}" enctype="multipart/form-data">
    @csrf
    @method('PATCH')

<?php 

public function update(Request $request, Category $category)
{
    $_val = request()->validate([
        'category_name'         => 'required|unique:categories',
        'category_description'  => 'required',
        'category_slug'         => 'required',
        'category_image'        => 'required|image',
    ]);

    $path = $request->file('category_image');
    $image = $path->getClientOriginalName();
    $path->move(public_path('images/backend_images/category_images'), $image);
    $_val['category_image'] = $image;

    $category = Category::find($request->id);
    $category->update($_val);


    return redirect('admin.category.index')->back()->with('flash_message_success', 'Category has been updated successfully');
}
