4. express
5. var express = require('express') var app = express() // respond with "hello world" when a GET request is made app.get('/', function (req, res) { res.send('hello world’) })
6. let router = Router() router.get("/") { request, response, next in response.send("Hello world") next() }
7. { "name": "", "photo": "", "dateOfBirth": { "year": "month": "day": } } struct Profile { var name: String var photo: Data var dateOfBirth: Date } Swift var profile: [String : Any] Swift KITURA
8. guard let name = json["name"].string else { response.status(.unprocessableEntity) response.send(json: JSON([ "error": "Type mismatch, `name` expected to be a String" ])) next() } guard json["photo"].exists() else { response.status(.unprocessableEntity) response.send(json: JSON([ "error": "Missing required property photo`" ])) next() } guard let photoString = json["photo"].string else { response.status(.unprocessableEntity) response.send(json: JSON([ "error": "Type mismatch, `photo` expected to be a String" ])) next() } guard let photo = Data(base64Encoded: photoString) else { response.status(.unprocessableEntity) response.send(json: JSON([ "error": "Type mismatch, `photo` expected to be Base64 encoded data" ])) next() }
9. struct Profile: Codable { var name: String var photo: Data var dateOfBirth: Date } router.post("/profile", handler: postProfile) func postProfile(request: RouterRequest, response: RouterResponse, next: () -> Void) { let profile = try request.read(as: Profile.Type) }
10. struct Profile: Codable { var name: String var photo: Data var dateOfBirth: Date } router.post("/profile", handler: postProfile) func postProfile(profile: Profile, respondWith: @escaping (Profile?, Error?) -> Void) { respondWith(profile, nil) }
