Client middleware logging

[daraghscopey]

I want to be able to add middleware to all requests and responses so that I can log to the database for analytics, cost management, and observability reasons. I can't seem to see an easy way to hook into the Prism Http client request/responses?

I see this trait is used with each provider, but it seems to be deliberately creating a clean PendingRequest without any middleware or exceptions:

trait InitializesClient
{
    protected function baseClient(): PendingRequest
    {
        return Http::withRequestMiddleware(fn (RequestInterface $request): RequestInterface => $request)
            ->withResponseMiddleware(fn (ResponseInterface $response): ResponseInterface => $response)
            ->throw();
    }
}

Within the providers, eg. OpenAI, there isn't a way to hook into anything from what I can see.

protected function client(array $options = [], array $retry = [], ?string $baseUrl = null): PendingRequest
    {
        return $this->baseClient()
            ->withHeaders(array_filter([
                'OpenAI-Organization' => $this->organization,
                'OpenAI-Project' => $this->project,
            ]))
            ->when($this->apiKey, fn ($client) => $client->withToken($this->apiKey))
            ->withOptions($options)
            ->when($retry !== [], fn ($client) => $client->retry(...$retry))
            ->baseUrl($baseUrl ?? $this->url);
    }

How are others handling being able to log all requests and responses?

I'm interested in this as well

I've used global middleware to achieve this. (And a macro to reset the global middleware after the request). You have to be careful with streams though; if you consume the stream response in the middleware it won't be consumed in the generator loop.

Do you mean this?

Are you setting it before the Prism call and removing after?

Yes indeed
