window.location.replace 不工作 Laravel ajax

Question

我是 laravel 的初学者。我使用 laravel Ajax 制作了自定义登录表单。当输入用户名和密码并单击登录按钮时，它成功访问 test.blade.php 页面，但页面显示 404 没有找到到目前为止我在下面附上的尝试。

test.blade.php

<div class="container">
    <table width="100%" height="100%" border="0" cellspacing="0" align="center">
        <tr>
            <td align="center" valign="middle">
                <table class="table-bordered" width="350" border="0" cellpadding="3" cellspacing="3" bgcolor="#FFFFFF">
                    <form name="frm_login" id="frm_login">
                    @csrf
                          <tr>
                              <td height="25" colspan="2" align="left" valign="middle" bgcolor="#FF9900" class="style2">

路线

Route::get('/test','TestloginController@index');
Route::post('/test/check','TestloginController@check')->name('testlogin.check');

Route::get('/test','TestloginController@index')->name('testlogin.login');

我检查了你的代码。您必须仅更改控制器中称为“检查”的操作（功能）。 请改为：

public function check(Request $request)
    {
        $credentials = $request->only('username', 'password');

        if (\Auth::attempt($credentials)) {
            return response()->json([[1]]);
        } else {
            return response()->json([[3]]);
        }
    }

之后你必须观看

            window.location.replace('test.blade.php');

改成

window.location.replace('{{route("your destination route name"}}');
