# Interface: DispatchInterceptor
|
|
|
|
Extends: `Function`
|
|
|
|
A function that can be applied to the `Dispatcher.Dispatch` function before it is invoked with a dispatch request.
|
|
|
|
This allows one to write logic to intercept both the outgoing request, and the incoming response.
|
|
|
|
### Parameter: `Dispatcher.Dispatch`
|
|
|
|
The base dispatch function you are decorating.
|
|
|
|
### ReturnType: `Dispatcher.Dispatch`
|
|
|
|
A dispatch function that has been altered to provide additional logic
|
|
|
|
### Basic Example
|
|
|
|
Here is an example of an interceptor being used to provide a JWT bearer token
|
|
|
|
```js
|
|
'use strict'
|
|
|
|
const insertHeaderInterceptor = dispatch => {
|
|
return function InterceptedDispatch(opts, handler){
|
|
opts.headers.push('Authorization', 'Bearer [Some token]')
|
|
return dispatch(opts, handler)
|
|
}
|
|
}
|
|
|
|
const client = new Client('https://localhost:3000', {
|
|
interceptors: { Client: [insertHeaderInterceptor] }
|
|
})
|
|
|
|
```
|
|
|
|
### Basic Example 2
|
|
|
|
Here is a contrived example of an interceptor stripping the headers from a response.
|
|
|
|
```js
|
|
'use strict'
|
|
|
|
const clearHeadersInterceptor = dispatch => {
|
|
const { DecoratorHandler } = require('undici')
|
|
class ResultInterceptor extends DecoratorHandler {
|
|
onHeaders (statusCode, headers, resume) {
|
|
return super.onHeaders(statusCode, [], resume)
|
|
}
|
|
}
|
|
return function InterceptedDispatch(opts, handler){
|
|
return dispatch(opts, new ResultInterceptor(handler))
|
|
}
|
|
}
|
|
|
|
const client = new Client('https://localhost:3000', {
|
|
interceptors: { Client: [clearHeadersInterceptor] }
|
|
})
|
|
|
|
```
