500（内部服务器错误） - 用户注册系统 - Laravel
500（内部服务器错误） - 用户注册系统 - Laravel
提问于 2019-08-05 05:53:21
所以，基本上我试图在Laravel中创建一个用户注册系统。注册表单验证效果很好，但在验证通过后我无法插入数据。相反，我得到了这个错误。任何帮助，将不胜感激。谢谢！
我试图使用查询构建器来插入数据。不幸的是，它仍然无效。
寄存器的script.js
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$(document).ready(function () {
$('#btnRegister').click(function (e) {
e.preventDefault();
$.ajax({
url: "/validate-register",
type: "post",
data: {
email: $('#exampleInputEmail1').val(),
username: $('#exampleInputUsername1').val(),
password: $('#exampleInputPassword1').val(),
confirmPassword: $('#exampleInputConfPassword1').val()
},
error: function (data) {
var errMsg = "";
var response = JSON.parse(data.responseText);
Object.keys(response.errors).forEach(function(k){
errMsg += '<li>' + response.errors[k] + '</li>'
}) ;
$('body').css({'overflow': 'visible'});
$('.alert').css({'display': 'block'});
$('.alert-danger').html(errMsg);
},
success:function(data){
window.location.href = '/';
}
});
});
});
寄存器Controller.php这样
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\DB;
use App\UserModel;
class RegisterController extends Controller
{
public function Index(){
return view('register');
}
public function ValidateRegister(Request $req){
$validatedData = $req->validate([
'email' => 'required|email',
'username' => 'required',
'password' => 'required|min:6',
'confirmPassword' => 'required|same:password'
]);
if(!$validatedData->fails())
insertNewUser($validatedData['email'],$validatedData['username'],Hash::make($validatedData['password']));
}
public function insertNewUser($email, $username, $password){
DB::table('users')->insert([
'email' => $email,
'username' => $username,
'password' => $password
]);
return response()->json(['response' => 'success']);
}
}
错误消息：
POST http://127.0.0.1:8000/validate-register 500 (Internal Server Error)
Uncaught TypeError: Cannot convert undefined or null to object

我没有尝试，但我认为当你使用$request->validate([rules...])它时不会返回验证器对象，而是返回已经验证为数组的字段。
所以你的控制器方法应该成为：
public function ValidateRegister(Request $req)
{
$validatedData = $req->validate([
'email' => 'required|email',
'username' => 'required',
'password' => 'required|min:6',
'confirmPassword' => 'required|same:password'
]);
return $this->insertNewUser(
$validatedData['email'],
$validatedData['username'],
Hash::make($validatedData['password'])
);
}
validate方法本身通过将错误作为响应返回来处理失败的验证
