Struct ServerActions

pub struct ServerActions<T: Caller> {
    pub caller: T,
}

Interface for services which serve http

The http-server service uses this interface to call into other services to respond to http requests.

To implement this interface, add a serveSys action to your service.

Fields

caller: T

Implementations

impl<T: Caller> ServerActions<T>

pub fn serveSys(&self, request: HttpRequest) -> T::ReturnType<Option<HttpReply>>

Handle HTTP requests

Define this action in your service to handle HTTP requests. You’ll also need to register your service by calling the registerServer action in the http-server service.

serveSys can do any of the following:

• Return None to signal not found. psinode produces a 404 response in this case.
• Abort. psinode produces a 500 response with the service’s abort message.
• Return a psibase::HttpReply. psinode produces a 200 response with the body and contentType returned.
• Call other services.
• Call http-server::sendReply. Explicitly sends a response.
• Call http-server::deferReply. No response will be produced until http-server::sendReply is called.

A service runs in RPC mode while serving an HTTP request. This mode prevents database writes, but allows database reads, including reading data and events which are normally not available to services; see psibase::DbId.
