我想按照这个教程Laravel 5和AJAX 的https：// WWW。 youtube.com/watch?v=PRCm-7mEDkY 这显然作品，但我得到一个500内部服务器错误在POST请求。我究竟做错了什么？我只是想了解一个简单的例子，并从那里工作了。

HTML

 ＆LT; A HREF =＃ID =得与GT;获取和LT; / A＆GT;
＆LT; HR＆GT;
＆LT;形式的行动=＃＆GT;
    ＆LT;输入类型=文本名称=名称＆GT;
    ＆LT;按钮类型=提交＆GT;发送和LT; /按钮＆GT;
＆LT; /形式GT;
 

JS

  $（函数（）{
    $（'＃GET）。点击（函数（五）{

        即preventDefault（）;

        $获得（'类'，功能（数据）{
            的console.log（数据）;
        }）;
    }）;

    $（形式）。递交（函数（五）{
        即preventDefault（）;

        .post的$（'类'，{名字：名字什么'}，功能（数据）{
            的console.log（数据）;
        }）;
    }）;

}）;
 

路线

 路线::职位（'/类'，函数（）{
    如果（支持::阿贾克斯（））{
        后续代码var_dump（输入::所有（））;
        回归AJAX POST请求;
    }
}）;

解决方案

在laravel 5 CSRF令牌是必需的所有职务的请求。您必须添加 _token 字段后请求体或添加标题 X-CSRF-TOKEN 。

一个可行的办法[如果JS是刀片模板中。

  $（函数（）{
$（'＃GET）。点击（函数（五）{

    即preventDefault（）;

    $获得（'类'，功能（数据）{
        的console.log（数据）;
    }）;
}）;

$（形式）。递交（函数（五）{
    即preventDefault（）;

    .post的$（'类'，{名字：名求什么，_token：{{csrf_token（）}}'}，功能（数据）{
        的console.log（数据）;
    }）;
}）;

}）;
 

I am trying to follow this tutorial for Laravel 5 and AJAX https://www.youtube.com/watch?v=PRCm-7mEDkY which obviously works, but am getting a 500 Internal Server Error on the Post Request. What am I doing wrong? I just want to understand a simple example and work up from there.

HTML

<a href="#" id="get">Get</a>
<hr>
<form action="#">
    <input type="text" name="name">
    <button type="submit">Send</button>
</form>

JS

$(function() {
    $('#get').click(function(e){

        e.preventDefault();

        $.get('categories', function(data) {
            console.log(data);
        });
    });

    $('form').submit(function(e) {
        e.preventDefault();

        $.post('categories', {name:'name anything'}, function(data) {
            console.log(data);
        });
    });

});

Route

Route::post('/categories', function() {
    if(Request::ajax() ) {
        var_dump(Input::all());
        return 'ajax post request';
    }
});

In laravel 5 csrf token is required for all post requests. You will have to add the _token field in post request body or add the header X-CSRF-TOKEN.

One possible solution [if the JS is inside the blade template].

$(function() {
$('#get').click(function(e){

    e.preventDefault();

    $.get('categories', function(data) {
        console.log(data);
    });
});

$('form').submit(function(e) {
    e.preventDefault();

    $.post('categories', {name:'name anything', _token: '{{ csrf_token() }}'}, function(data) {
        console.log(data);
    });
});

});
