Laravel HttpException - 没有错误消息答案

【问题标题】：Laravel HttpException - No error messageLaravel HttpException - 没有错误消息
【发布时间】：2017-10-11 16:19:21
【问题描述】：

我无法获得针对我的应用程序的 ajax 请求的描述性错误消息。我看不出这是如何设置的问题。我已经尝试完全删除控制器方法，但在它接触控制器之前仍然失败。

我的路线：

+--------+----------+------------------------+-------+--------------------------------------------------------------+---------------------------------+
| Domain | Method   | URI                    | Name  | Action                                                       | Middleware                      |
+--------+----------+------------------------+-------+--------------------------------------------------------------+---------------------------------+
|        | POST     | subscribe              |       | App\Http\Controllers\SubscriptionController@create           | web,auth                        |
+--------+----------+------------------------+-------+--------------------------------------------------------------+---------------------------------+

在 web.php 中：

Route::group([
    'middleware' => 'auth',
], function () {
    Route::post('subscribe', 'SubscriptionController@create');
    Route::post('unsubscribe', 'SubscriptionController@delete');
});

我的 VueJS：

this.$http.post('/subscribe', {
    my-data: 'values'
}).then(response => {
    // success
}, response => {
    console.error('Failed to subscribe');
});

【问题讨论】：

你能显示 SubscriptionController 的代码吗？
@wanghanlin 我可以，但这没关系，因为我可以完全删除该类并且仍然得到相同的错误。
我认为你应该在 api 部分写这条路线，因为在网络上有一个CSRF 验证，这就是为什么你有 419 状态码作为响应！
这很有道理......我认为 VueJS 被引导来处理 CSRF。如果它是对我自己网站的 ajax 请求，我真的不需要身份验证，我更愿意使用 CSRF 作为一种安全形式，而不是通过 api 密钥锁定端点。

标签： laravel

【解决方案1】：

在网页部分（web.php 路由文件）有一个CSRF 验证，其中VerifyCsrfToken 中间件作为doc sais：

VerifyCsrfToken 中间件，包含在网络中中间件组，会自动验证请求输入与会话中存储的令牌匹配。

这就是为什么你有 419 状态码作为响应。

并且在 API 部分（api.php 路由文件）中，witch 专用于“无状态”API 调用，没有 CSRF 验证，但您应该通过 JWT 或 Laravel Passport 使用 API 验证例子。

因此，如果您想使用 web 部分，您应该为您的 ajax 调用添加 X-CSRF-TOKEN 标头，并使用生成的 csrf_token 的值，您可以从元标记中获取它，例如：

<meta name="_token" content="{{ csrf_token() }}"/>

然后在ajax调用之前使用$.ajaxSetup：

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
    }
});

$.ajax({
    url: "/subscribe",
    // ....
})

【讨论】：

多考虑一下 - ajax 请求不会破坏 CSRF 吧？
谢谢。这对我有帮助。几个建议。 1）api.jquery.com/jquery.ajaxsetup 说，“不推荐使用它”，因为对其他库的全球影响。我使用“beforeSend”来设置我的 ajax 调用中的标题。 2）我不得不将“_token”更改为“csrf-token”。（不过我是 laravel 新手，所以我不知道这是否是我的环境或版本所独有的。）
