【问题描述】：
我正在尝试做一个 Ajax 帖子，以允许人们在安装程序中途测试数据库连接，但我经常收到此错误：
Failed to load resource: the server responded with a status of 405 (HTTP/2.0 405)

我以 3 种不同的方式将 CSRF 令牌添加到 Ajax 设置中。我已经通过 php artisan route:list 检查了我的路线。我同时使用了 $.ajax 和 $.post。我已经更改了我的路由 url，以便它们与任何 get 请求都不匹配（因为有时它会从 get 中返回 html）。最后，我禁用了 CSRF 保护，并使用 Postman 进行了测试，一切正常，所以前端代码有问题。
前端代码：
{!! Form::open(array('route' => 'postInstall', 'class' => 'f1 install', 'method' => 'put')) !!}

我不知道我做错了什么，我检查了每个帖子并尝试了几乎所有方法。 （可能是我错过的一些小东西）
我使用的是最新版本的 laravel。
【问题讨论】：
-
要补充的是，当我同时使用 $.post() 和 $.ajax 并将类型和方法设置为 post 时，JQuery 作为 Get 而不是 Post 发送。解决这个问题的唯一方法是当我为 $.ajax 设置 contentType 但我无法在后端读取它，就好像它是一个表单一样。
-
您使用了哪种内容类型。你试过'multipart/form-data'吗？
-
我尝试将 json 作为内容类型，这有点工作，但我无法访问数据。我会试试你列出的 2 个。
-
好的，我尝试了“multipart/form-data”，结果与使用 json 作为内容类型时所做的完全相同。
