Swift【1】 语言实现娱乐活动报名与参与系统

随着移动互联网的快速发展，各类线上娱乐活动层出不穷。为了方便用户参与这些活动，同时提高活动的组织效率，我们可以使用 Swift 语言开发一个简单的娱乐活动报名与参与系统。本文将围绕这一主题，从系统设计、功能实现、技术选型等方面进行详细阐述。

一、系统设计

1. 系统架构

本系统采用前后端分离的架构，前端使用 Swift 语言开发的 iOS 应用，后端使用 Swift 语言开发的 Serverless【2】 云函数。系统架构图如下：


+------------------+ +------------------+ +------------------+
| | | | | |
| iOS 应用 +------>+ Serverless 云函数 +------>+ 数据库 |
| | | | | |
+------------------+ +------------------+ +------------------+

2. 功能模块

本系统主要包含以下功能模块：

- 用户模块：用户注册、登录、个人信息管理。
- 活动模块：活动发布、活动列表、活动详情、报名、取消报名。
- 管理模块：管理员登录、活动管理【3】、用户管理【4】。

二、功能实现

1. 用户模块

用户注册

swift
func register(username: String, password: String, completion: @escaping (Bool, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/register")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = ["username": username, "password": password].jsonData()

URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
completion(false, error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(false, "请求失败")
return
}

completion(true, "注册成功")
}.resume()
}

用户登录

swift
func login(username: String, password: String, completion: @escaping (Bool, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/login")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = ["username": username, "password": password].jsonData()

URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
completion(false, error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(false, "请求失败")
return
}

completion(true, "登录成功")
}.resume()
}

2. 活动模块

活动发布

swift
func publishActivity(title: String, description: String, completion: @escaping (Bool, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/activity/publish")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = ["title": title, "description": description].jsonData()

URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
completion(false, error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(false, "请求失败")
return
}

completion(true, "活动发布成功")
}.resume()
}

活动列表

swift
func fetchActivities(completion: @escaping ([Activity], String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/activity/list")!
URLSession.shared.dataTask(with: url) { data, response, error in
if let error = error {
completion([], error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion([], "请求失败")
return
}

do {
let activities = try JSONDecoder().decode([Activity].self, from: data)
completion(activities, "获取活动列表成功")
} catch {
completion([], error.localizedDescription)
}
}.resume()
}

活动详情

swift
func fetchActivityDetail(id: Int, completion: @escaping (Activity, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/activity/detail/(id)")!
URLSession.shared.dataTask(with: url) { data, response, error in
if let error = error {
completion(Activity(), error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(Activity(), "请求失败")
return
}

do {
let activity = try JSONDecoder().decode(Activity.self, from: data)
completion(activity, "获取活动详情成功")
} catch {
completion(Activity(), error.localizedDescription)
}
}.resume()
}

报名

swift
func enrollActivity(id: Int, completion: @escaping (Bool, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/activity/enroll/(id)")!
var request = URLRequest(url: url)
request.httpMethod = "POST"

URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
completion(false, error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(false, "请求失败")
return
}

completion(true, "报名成功")
}.resume()
}

取消报名

swift
func cancelEnrollActivity(id: Int, completion: @escaping (Bool, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/activity/cancelEnroll/(id)")!
var request = URLRequest(url: url)
request.httpMethod = "POST"

URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
completion(false, error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(false, "请求失败")
return
}

completion(true, "取消报名成功")
}.resume()
}

3. 管理模块

管理员登录

swift
func adminLogin(username: String, password: String, completion: @escaping (Bool, String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/admin/login")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = ["username": username, "password": password].jsonData()

URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
completion(false, error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion(false, "请求失败")
return
}

completion(true, "管理员登录成功")
}.resume()
}

活动管理

swift
func manageActivities(completion: @escaping ([Activity], String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/admin/activity/list")!
URLSession.shared.dataTask(with: url) { data, response, error in
if let error = error {
completion([], error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion([], "请求失败")
return
}

do {
let activities = try JSONDecoder().decode([Activity].self, from: data)
completion(activities, "获取活动列表成功")
} catch {
completion([], error.localizedDescription)
}
}.resume()
}

用户管理

swift
func manageUsers(completion: @escaping ([User], String) -> Void) {
// 模拟网络请求
let url = URL(string: "https://api.example.com/admin/user/list")!
URLSession.shared.dataTask(with: url) { data, response, error in
if let error = error {
completion([], error.localizedDescription)
return
}

guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
completion([], "请求失败")
return
}

do {
let users = try JSONDecoder().decode([User].self, from: data)
completion(users, "获取用户列表成功")
} catch {
completion([], error.localizedDescription)
}
}.resume()
}

三、技术选型

1. 前端

- Swift 语言：用于开发 iOS 应用。
- SwiftUI【5】：用于构建用户界面。
- Alamofire【6】：用于网络请求。

2. 后端
