如何在使用多个数据库和涉及映像的情况下更新请求

Question

尝试创建API，其中用户创建一个包含食物标题和烹饪时间的帖子，并且他们可以在两个表中发布最多2张图片，在两个不同的数据库中发布post_images。 存储功能运行良好，但是我对更新功能一无所知。我可以通过邮递员更新所有帖子数据，但是图像没有更新

public function store(Request $request)
{
    $post = new Post;
    $post->setConnection('mysql1');
    $user = User::where('id', $request->id)->first();
    if ($user) {
        $post =  Auth::user()->posts()->create([
            'user_id' => Auth::id(),
            'post_id' => rand(),
            'title' => $request->title,
            'cooked_time' => strtotime($request->cooked_time),
        ]);
        $images = new PostImage;
        $destination_path = public_path('/images');
        if ($request->hasFile('image1')) {
            $image1 = $request->file('image1');
            $image_size1 = $image1->getClientSize();
            $image_ext1 = $image1->getClientOriginalExtension();
            $new_image_name1 = rand(123456, 99999999) . "." . $image_ext1;
            $image1->move($destination_path, $new_image_name1);
            $images->image_name1 = $new_image_name1;
        }
        if ($request->hasFile('image2')) {
            $image2 = $request->file('image2');
            $image_size2 = $image2->getClientSize();
            $image_ext2 = $image2->getClientOriginalExtension();
            $new_image_name2 = rand(123456, 99999999) . "." . $image_ext2;
            $image2->move($destination_path, $new_image_name2);
            $images->image_name2 = $new_image_name2;
        }
        $images->post_id = $post->post_id;
        $images->save();
        $post = json_decode($post);
        $post->image1 = $images->image_name1;
        $post->image2 = $images->image_name2;
        if ($post && $images) {
            return $this->successResponse($post);
        } else {
            return $this->errorResponse("Post Failed", 200);
        }
    }
}

我的更新代码有点类似

public function update(Request $request, $post_id)
{
    $posts = Post::findorFail($post_id);
    if (Auth::user()->id !== $posts->user_id) {
        return response()->json(['status' => 'error', 'message' => 'unauthorized'], 401);
    }
    $post1 = $request->all();
    $posts->fill($post1)->save();
    $image = PostImage::where('post_id', $posts->post_id)->get()->first();
    $images = PostImage::findorFail($image->id);
    if ($request->hasFile('image1')) {
        $image1 = $request->file('image1');
        $image_size1 = $image1->getClientSize();
        $image_ext1 = $image1->getClientOriginalExtension();
        $new_image_name1 = $post_image['image_name1'] . "." . $image_ext1;
        $image1->move($destination_path, $new_image_name1);
        $images->image_name1 = $new_image_name1;
    }
    if ($request->hasFile('image2')) {
        $image2 = $request->file('image2');
        $image_size2 = $image2->getClientSize();
        $image_ext2 = $image2->getClientOriginalExtension();
        $new_image_name2 = $post_image['image_name2'] . "." . $image_ext2;
        $image2->move($destination_path, $new_image_name2);
        $images->image_name2 = $new_image_name2;
    }
    $images->post_id = $post->post_id;
    $images->save();
    return response()->json(['status' => 'success', 'updated_post' => $posts, 'images' => $images], 200);
}

如果要通过邮递员传递图像参数，我想实现更新请求以同时更新图像和帖子。
