Question

因此，我有一个{strong>原始应用程序，用于cliets。我已经使用Laravel做到了，现在我想在 ApiController 中创建组件，仅使其与 Postman 一起使用。

当我使用POST时，错误：Creating default object from empty value（在$ client-> clt_name处）

当我使用GET时，它只会在message中显示验证错误

这是API

public function clients(Request $request){

    $validator = Validator::make($request->all(), [
        'name'          =>  'regex:/^[^{}<>]+$/u|max:255|required',
        'adress'         => 'regex:/[A-Za-z0-9\-\\,.]+/'
    ]);

    if($validator->fails()){
        $message = "Please fill in the right information";
        return $this->sendError('Validation Error.' . $message);        
    }

    $client_id = $request->clt_id;

    $client->clt_name = $request->name; 
    $client->clt_adres = $request->adress;
    $client->save();


    $client = client::where('clt_id', $client_id)->first();
    if($client){
        if(!is_null($client)){
            return $this->sendError("404", 'client not found');
        }
    }
    else{
        //new client
        $client = new client; 
    }         
}

和删除功能：

public function delete_client(Request $request){
        $client = client::find($id);
        $client->delete();    
    }

我对制作API还是很陌生，因此，我们将不胜感激。

我希望这就是您要寻找的

public function clients(Request $request)
{
    $validator = Validator::make($request->all(), [
        'name'          =>  'regex:/^[^{}<>]+$/u|max:255|required',
        'adress'         => 'regex:/[A-Za-z0-9\-\\,.]+/'
    ]);

    if($validator->fails()){
        $message = "Please fill in the right information";
        return $this->sendError('Validation Error.' . $message);        
    }

    $client_id = $request->clt_id;
    $clt_name = $request->name; 
    $clt_adres = $request->adress;

    return client::updateOrCreate(
        ['clt_id' => $client_id],
        ['clt_name' => $clt_name, 'clt_adres' => $clt_adres]
    );     
}

如果没有clt_id，这将创建新客户端，否则将更新客户端。

尝试这种方式

创建对象并分配值

 $client= new Client;  //your table name
 $client->clt_name = $request->name; 
 $client->clt_adres = $request->adress;
 $client->save();

检查：

public function clients(Request $request){

  $validator = Validator::make($request->all(), [
    'name'          =>  'regex:/^[^{}<>]+$/u|max:255|required',
    'adress'         => 'regex:/[A-Za-z0-9\-\\,.]+/'
  ]);

  if($validator->fails()){
    $message = "Please fill in the right information";
    return $this->sendError('Validation Error.' . $message);        
  }

  $client = client::where('clt_id', $request->clt_id)->first();

  if($client !== null){
    // update client - all fields must be fillable in client model
    $client = $client->update($request->except('clt_id'));
  } else{
    //new client - all fields must be fillable in client model
    $client = Client::create($request->all());
  }

  return response()->json($client);
}

使用Postman在API中使用CRUD应用程序
