如何使用“DELETE"发送请求?HTTP动词? [英] How do you send a request with the "DELETE" HTTP verb?

问题描述

我想在执行此操作的 Rails 应用程序的视图中创建一个链接...

I'd like to create a link in a view within a Rails application that does this...

DELETE /sessions

我该怎么做.

增加了复杂性:

会话"资源没有模型，因为它代表用户登录会话.CREATE 表示用户登录，DESTROY 表示退出.

The "session" resource has no model because it represents a user login session. CREATE means the user logs in, DESTROY means logs out.

这就是 URI 中没有 ID 参数的原因.

That's why there's no ID param in the URI.

我正在尝试在 UI 中实现注销"链接.

I'm trying to implement a "log out" link in the UI.

推荐答案

正确，浏览器实际上并不支持发送删除请求.许多 Web 框架接受的约定是发送设置为DELETE"的 _method 参数，并使用 POST 请求.

Correct, browsers don't actually support sending delete requests. The accepted convention of many web frameworks is to send a _method parameter set to 'DELETE', and use a POST request.

这是 Rails 中的一个示例:

Here's an example in Rails:

<%= link_to 'log out', session_path, :method => :delete %>
