我使用的工具是：Postman发出请求并获得响应。**
问题出:**
我尝试上传图像并从服务器获取它们，每张图像都是一个特定的公寓。
例如：
如果我在公寓表中有 image*1.png ， images2.png image3.png 和 apartment1 ，apartment2，
然后我想把image1.png和image放到apartment1，把image*3放到apartment2。
在此示例中，id -> 1 和 -> 3 到 apartment_id -> 1 的照片表应如下所示： https://mydomen/public/images/apartments_image/image1.png
https://mydomen/public/images/apartments_image/image1.png
id 3 和 apartment_id -> 2 表应该是这样的
https://mydomen/public/images/apartments_image/image3.png
在Laravel中，不只使用html，JSON和API，我是移动应用程序开发人员，我使用邮递员OK。
那么如何在Laravel中使用这个问题呢？
[可选] 如果你知道 Flutter，如何为上面的响应编写代码？
我尝试了这段代码：
public function addImageds( request $request){
{
$request->validate([
'apartment_id' => 'required|exists:apartments,id',
'images' => 'required|array',
'images.*' => 'image|mimes:jpeg,png,jpg|max:2048',
]);
$apartmentId = $request->input('apartment_id');
$images = $request->file('images');
$uploadedImageIds = [];
foreach ($images as $image) {
$path = $image->store('your_directory');
$photo = new Photo();
$photo->apartment_id = $apartmentId;
$photo->url = $path;
$photo->save();
$uploadedImageIds[] = $photo->id;
}
return response()->json(['message' => 'Images uploaded successfully', 'image_ids' => $uploadedImageIds]);
}
}
响应为 200，但路径中未保存任何照片。
我用来在路径中显示图像的另一个代码：
public function showImages($apartment_id)
{
$photos = Photo::where('apartment_id', $apartment_id)->get();
$imageUrls = $photos->pluck('url')->toArray();
return response()->json(['image_urls' => $imageUrls]);
}
上面代码的响应是这样的：
空数组。

这是我在 Flutter App 中使用的 Laravel 图像保存 API 示例。在我的应用程序中，图像是逐个发送的，但对于您的情况，您只需要循环执行即可。
if($request->hasFile('Image')){
$filenameWithext=$request->file('Image')->getClientOriginalName();
$extension=$request->file('Image')->getClientOriginalExtension();
$fileNameToStore='image_'.round(microtime(true) * 1000).'.'.$extension;
$path=$request->file('Image')->storeAs('public/images/apartments_image',$fileNameToStore);
}
尝试在图像数组上使用此技术，并注意 StoreAs 生成的返回路径，您可能需要对其进行一些更改。
