EdgeDB WebAssembly SDK

示例

此SDK的主要用途是创建一个Web处理程序，并在该处理程序中执行一些数据库查询。一个非常简单的示例

use edgedb_sdk::web;
use edgedb_sdk::client::{Client, create_client};
use once_cell::sync::Lazy;

static CLIENT: Lazy<Client> = Lazy::new(|| create_client());

#[web::handler]
fn handler(_req: web::Request) -> web::Response {
    let query_result = CLIENT.query_required_single::<i64, _>(
        "SELECT 7*8",
        &(),
    );
    match query_result {
        Ok(value) => {
            web::response()
                .status(web::StatusCode::OK)
                .header("Content-Type", "text/html")
                .body(format!("7 times 8 is {value}").into())
                .expect("response is built")
        }
        Err(e) => {
            log::error!("Error handling request: {:#}", e);
            web::response()
                .status(web::StatusCode::INTERNAL_SERVER_ERROR)
                .header("Content-Type", "text/plain")
                .body(format!("Internal Server Error").into())
                .expect("response is built")
        }
    }
}
