You are using this:
你正在使用这个：
$tecnico = Tecnico::with('servicios')->where('Auth_Token',$auth)->firstOrFail();
In this case, firstOrFailthrows Illuminate\Database\Eloquent\ModelNotFoundExceptionexception if it doesn't find the requested model and hence it could be because the model with that Auth_Tokenfield is not available.
在这种情况下，如果找不到请求的模型，则firstOrFail抛出Illuminate\Database\Eloquent\ModelNotFoundException异常，因此可能是因为具有该Auth_Token字段的模型不可用。
Make sure the Auth_Tokenis right and that Auth_Tokenis available in your database. You may try a dd(Input::get('Auth_Token'))to check what you have recieved from the POSTsubmitted by the user.
确保Auth_Token正确并且Auth_Token在您的数据库中可用。您可以尝试dd(Input::get('Auth_Token'))检查从POST用户提交的内容中收到的内容。
