在vapor4中返回合理的数据

import Vapor

struct User: Content, Codable {
    var id: UUID?
    var name: String
    var email: String
}

import Vapor

func routes(_ app: Application) throws {
    app.get("users", use: listUsers)
}

func listUsers(_ req: Request) throws -> EventLoopFuture<[User]> {
    let users = [
        User(id: UUID(), name: "Alice", email: "alice@example.com"),
        User(id: UUID(), name: "Bob", email: "bob@example.com")
    ]
    return req.eventLoop.makeSucceededFuture(users)
}

import Vapor

let app = Application()

defer { app.shutdown() }

try configure(app)

try app.run()

func listUsers(_ req: Request) throws -> EventLoopFuture<[User]> {
    do {
        let users = try User.query(on: req.db).all()
        return req.eventLoop.makeSucceededFuture(users)
    } catch {
        return req.eventLoop.makeFailedFuture(error)
    }
}
