Actix web client
The API gateway can enrich the API calls on behalf of the client (aka one client call can execute and return results from multiple micro services).ĭrawbacks: you have to develop and maintain the logic of the API gateway in code, which usually means more time and effort when compared to the configuration approach in 1. a custom API gateway for web and mobile clients). As of this you will have to implement the API gateway as a kind of server with a custom API as well as acting as a client to your micro services.īenefits: the API of the API gateway hides the internal API of your services and can be customized for clients (e.g. Any client request received on its own API will be translated into subsequent calls to micro services. In this case the API gateway offer an own API that is either a subset or mixture of the APIs exposed by the micro services. We had an overview of the project structure. The API gateway acts as a client side facade in front of your fleet of micro services. REST API with Rust, Actix-web, and PostgreSQL Part 3 This is the last part of our REST API Actix-web PostgreSQL post.
#Actix web client code
Here you can just use a reverse proxy configuration ala nginx.īenefits: no need to code the API gateway, just configure the reverse proxy.ĭrawbacks: it doesn’t hide the internal APIs of the micro services. The exposed API is fitting 1:1 to the ones from the micro services and the API gateway just bundle them into one endpoint for the client. The API gateway simply forwards the requests from the client to the responsible service. There are usually two ways how you do an API gateway in a micro service architecture: Now I'll need to handle GraphQL requests, the problem will be handling more than one GraphQL service (because the federation implementation in juniper is missing) and handling "protected" queries (that require authentication) Is there a way to forward requests with actix-web (or hyper/other frameworks)?
#Actix web client how to
I can't find a way to forward requests to the other services adding some custom headers to identify the user and the microservice, I could solve this with a client like reqwest or the actix-web Client but then I have the problem to pass the multipart request to the upload service, the other services send and receive JSON so it's not a big deal to create a new request with the new body and the microservice identification tokens and send it, the "problem" could be how to async it.įor the client solution, how can I build a new multipart request with all the files sent to the API? Most of them are ready but I'm encountering some problems when creating an API Gateway. The microservices are a GraphQL service, an auth service and an upload service. Hello, I'm trying to create a microservice architecture backend in rust with Actix to learn both actix and the microservices architecture.
