Rust

Empieza por la guía de gRPC para obtener un token API de la plataforma y descargar platform.proto. Este ejemplo utiliza tonic y tonic-prost-build para generar un cliente HTTP/2 nativo. Instala primero Rust y protoc.

Crea un proyecto y coloca el contrato descargado en proto/platform.proto:

cargo new reconstruct-client
cd reconstruct-client
mkdir proto

Utiliza este Cargo.toml:

[package]
name = "reconstruct-client"
version = "0.1.0"
edition = "2021"

[dependencies]
prost = "0.14"
tokio = { version = "1", features = ["macros", "rt-multi-thread"] }
tonic = { version = "0.14", features = ["transport", "tls-ring", "tls-native-roots"] }
tonic-prost = "0.14"

[build-dependencies]
tonic-prost-build = "0.14"

Genera los tipos del cliente durante la compilación con build.rs en la raíz del proyecto:

fn main() -> Result<(), Box<dyn std::error::Error>> {
    tonic_prost_build::configure()
        .build_server(false)
        .compile_protos(&["proto/platform.proto"], &["proto"])?;
    Ok(())
}

Utiliza el cliente generado en src/main.rs:

use std::env;
use tonic::{transport::{Channel, ClientTlsConfig}, Request};

pub mod platform {
    tonic::include_proto!("reconstruct.platform.v1");
}

use platform::{
    platform_service_client::PlatformServiceClient,
    GetCatalogRequest, ListCatalogsRequest,
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let token = env::var("CR_RECONSTRUCT_API_TOKEN")?;
    let channel = Channel::from_static("https://reconstruct.dev")
        .tls_config(ClientTlsConfig::new().with_native_roots())?
        .connect()
        .await?;
    let mut client = PlatformServiceClient::new(channel);

    let mut request = Request::new(ListCatalogsRequest {
        page_size: 10,
        page_token: String::new(),
    });
    request.metadata_mut().insert("authorization", format!("Bearer {token}").parse()?);
    let page = client.list_catalogs(request).await?.into_inner();

    for catalog in page.catalogs {
        let mut request = Request::new(GetCatalogRequest { catalog_id: catalog.catalog_id });
        request.metadata_mut().insert("authorization", format!("Bearer {token}").parse()?);
        let detail = client.get_catalog(request).await?.into_inner();
        println!("{}: {}", detail.catalog_id, detail.description);
    }
    Ok(())
}

Ejecuta cargo run. El gRPC nativo se conecta a la autoridad HTTPS; /api/v1/platform es solo para REST.
