Http.Request and http.responsewriter in container

[rotembo]

How do I inject those in the container for each http request (under request scope)

Hello,

you can write a service containing the request and the response.

type RequestData struct {
	Request        *http.Request
	ResponseWriter http.ResponseWriter
}

then you can write a middleware that retrieves the service from the container and fills its fields.

But it is not a good idea to do that, because it can conflict with other middleware if they copy the request or the response writer.

For example the di middleware copies the request to update its context: https://github.com/sarulabs/di/blob/master/http.go#L38

If you really want to do that, the RequestData must be filled by the last middleware. Also you must be sure not to use other services depending on RequestData in other middlewares, because it won't be filled at that time.
