一、打开终端：
1、新建一个SwiftPerfectDemo文件夹用于保存项目文件：
mkdir SwiftPerfectDemo
cd SwiftPerfectDemo
2、初始化git：
git init
touch README.html
git add README.html
git commit -m "Initial commit"
3.创建Package.swift文件:
touch Package.swift
4、使用Xcode打开Package.swift文件并添加如下代码，添加所需要使用的软件包：
//软件包管理 import PackageDescription let versions = Version(0,0,0)..<Version(10,0,0) let urls = [ "https://github.com/PerfectlySoft/Perfect-HTTPServer.git", //HTTP服务 "https://github.com/PerfectlySoft/Perfect-MySQL.git", //MySQL服务 "https://github.com/PerfectlySoft/Perfect-Mustache.git" //Mustache ] let package = Package( name: "PerfectDemoProject", targets: [], dependencies: urls.map { .Package(url: $0, versions: versions) } )
5、创建Sources文件夹：
mkdir Sources
echo 'print("Hello")'>>Sources/main.swift
6、编译运行项目
编译：swift build
运行：.build/debug/SwiftPerfectDemo
注意：此处编译如果报错，请查看Xcode路径
xcode-select -p
显示不是为/Applications/Xcode.app/Contents/Developer，则更改：
unset DEVELOPER_DIR
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
7、创建成Xcode可以运行项目：
swift package generate-xcodeproj
二、使用Xcode
1、打开PerfectDemoProject.xcodeproj
注意: 若在编辑过程中无其他问题且无法运行,请删除PerfectDemoProject.xcodeproj文件,重新使用swift package generate-xcodeproj命令创建
三、搭建HTTP服务器
1.编辑main.swift
import PerfectLib import PerfectHTTP import PerfectHTTPServer //HTTP服务 let networkServer = NetworkServerManager(root: "webroot", port: 8888) networkServer.startServer()
2.创建并编辑NetworkServerManager.swift
import PerfectLib import PerfectHTTP import PerfectHTTPServer open class NetworkServerManager { fileprivate var server: HTTPServer internal init(root: String, port: UInt16) { server = HTTPServer.init() //创建HTTPServer服务器 var routes = Routes.init(baseUri: "/api") //创建路由器 configure(routes: &routes) //注册路由 server.addRoutes(routes) //路由添加进服务 server.serverPort = port //端口 server.documentRoot = root //根目录 server.setResponseFilters([(Filter404(), .high)]) //404过滤 } //MARK: 开启服务 open func startServer() { do { print("启动HTTP服务器") try server.start() } catch PerfectError.networkError(let err, let msg) { print("网络出现错误：\(err) \(msg)") } catch { print("网络未知错误") } } //MARK: 注册路由 fileprivate func configure(routes: inout Routes) { // 添加接口,请求方式,路径 routes.add(method: .get, uri: "/") { (request, response) in response.setHeader( .contentType, value: "text/html") //响应头 let jsonDic = ["hello": "world"] let jsonString = self.baseResponseBodyJSONData(status: 200, message: "成功", data: jsonDic) response.setBody(string: jsonString) //响应体 response.completed() //响应 } } //MARK: 通用响应格式 func baseResponseBodyJSONData(status: Int, message: String, data: Any!) -> String { var result = Dictionary<String, Any>() result.updateValue(status, forKey: "status") result.updateValue(message, forKey: "message") if (data != nil) { result.updateValue(data, forKey: "data") }else{ result.updateValue("", forKey: "data") } guard let jsonString = try? result.jsonEncodedString() else { return "" } return jsonString } //MARK: 404过滤 struct Filter404: HTTPResponseFilter { func filterBody(response: HTTPResponse, callback: (HTTPResponseFilterResult) -> ()) { callback(.continue) } func filterHeaders(response: HTTPResponse, callback: (HTTPResponseFilterResult) -> ()) { if case .notFound = response.status { response.setBody(string: "404 文件\(response.request.path)不存在。") response.setHeader(.contentLength, value: "\(response.bodyBytes.count)") callback(.done) } else { callback(.continue) } } } }
3.运行结果：
控制面板会打印出：启动HTTP服务器；证明OK啦
4.访问接口效果：
浏览器输入：http://0.0.0.0:8888/api/
