php - 为什么 Lumen 采用数组到字符串的转换？
问题描述
我对 Lumen 的 POST 请求中有以下 JSON 有效负载：
{ "array":
[
{"title":"my blogADD","description":"myblogdescriptionADD","status":1},
{"title":"my blogUPDATEDADD","description":"myblogdescriptionUPDATEDADD","status":1},
{"title":"my blog33ADD","description":"myblogdescription33ADD","status":1}
]
}
POST 在我的控制器中调用以下端点：
$this->validate($request, [
'array' => 'present|array',
'array.*.title' => 'required',
'array.*.description' => 'required'
]);
为了完整性，这里是我的 ArticleController.php 的完整代码：
<?php
namespace App\Http\Controllers;
use App\Article;
use Illuminate\Http\Request;
class ArticleController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
//
}
//
public function showAllArticles(){
return response()->json(Article::get(['title', 'description', 'status'])); // ::get([]) spezifiziert die zu referenzierenden Attribute
// ::all() referenziert alle Attribute einer Tabelle/Relation
}
public function showOneArticle($id){
return response()->json(Article::find($id));
}
public function create(Request $request){
$this->validate($request, [
'array' => 'present|array',
'array.*.title' => 'required',
'array.*.description' => 'required'
]);
//dd($request->all());
/*
$this->validate($request, [
'title' => 'required',
'description' => 'required'
]);*/
//insert record
//$article = Article::create($request->all());
Article::insert($request->all());
//return response()->json($article, 201);
}
public function update($id, Request $request){
$this->validate($request, [
'title' => 'required',
'description' => 'required'
]);
$article = Article::findOrFail($id);
$article->update($request->all());
return response()->json($article, 200);
}
public function delete($id, Request $request){
Article::findOrFail($id)->delete();
return response('Deleted Successfully', 200);
}
public function resetRecords(Request $request){
Article::where('id', '>', 2)->delete();
}
}
现在，当我提出请求时，我收到以下错误：

我从 Michael Aaron Wilson 的 SO 回答中得到了我的代码和 JSON 请求的上述语法： Laravel validate array of object json
这不是公认的答案，但它似乎比公认的答案更适合我的问题。但也许我在这里错了，我对 lumen 很陌生，我目前在使用 lumen 助手时面临最多的问题 ->validate()
也许你们中的某个人可以告诉我所引用问题中建议的解决方案是否已经错误，或者我的代码是否错误或我的 JSON 对象数组。
编辑：我的 $request 的调试呈现以下结果：
