方法覆盖中间件

¥Method Override Middleware

此中间件根据表单、标头或查询的值执行指定方法的处理程序（该方法与请求的实际方法不同），并返回其响应。

¥This middleware executes the handler of the specified method, which is different from the actual method of the request, depending on the value of the form, header, or query, and returns its response.

导入

¥Import

import { Hono } from 'hono'
import { methodOverride } from 'hono/method-override'

用法

¥Usage

const app = new Hono()

// If no options are specified, the value of `_method` in the form,
// e.g. DELETE, is used as the method.
app.use('/posts', methodOverride({ app }))

app.delete('/posts', (c) => {
  // ....
})

例如

¥For example

由于 HTML 表单无法发送 DELETE 方法，你可以将值 DELETE 放在名为 _method 的属性中并发送它。app.delete() 的处理程序将被执行。

¥Since HTML forms cannot send a DELETE method, you can put the value DELETE in the property named _method and send it. And the handler for app.delete() will be executed.

HTML 表单：

¥The HTML form:

<form action="/posts" method="POST">
  <input type="hidden" name="_method" value="DELETE" />
  <input type="text" name="id" />
</form>

应用：

¥The application:

import { methodOverride } from 'hono/method-override'

const app = new Hono()
app.use('/posts', methodOverride({ app }))

app.delete('/posts', () => {
  // ...
})

你可以更改默认值或使用标头值和查询值：

¥You can change the default values or use the header value and query value:

app.use('/posts', methodOverride({ app, form: '_custom_name' }))
app.use(
  '/posts',
  methodOverride({ app, header: 'X-METHOD-OVERRIDE' })
)
app.use('/posts', methodOverride({ app, query: '_method' }))
