序言：
1.以下代碼中的意義，會(huì)在代碼里解釋，用比較容易理解的詞語(yǔ)注釋，若有晦澀之處，可私信于我。
2.現(xiàn)已假設(shè)讀者閱讀過(guò)我的另外兩篇文章??
Swift Perfect開發(fā)你的服務(wù)器（初級(jí)版）
Swift Perfect開發(fā)你的服務(wù)器（中級(jí)版）
3.準(zhǔn)備Peffect助手工具：Perfect Assistant 3.0創(chuàng)建服務(wù)器項(xiàng)目
基于“以上”編譯成功后，在默認(rèn)的main.swift文件里，全部清空，然后替換成我的代碼：
// 導(dǎo)入所需要的庫(kù)
import PerfectLib
import PerfectHTTP
import PerfectHTTPServer
import PerfectMustache
import Foundation
let root = "./webroot"
// 配置服務(wù)器端口、根目錄等
let server = HTTPServer()
server.serverPort = 8181
server.documentRoot = root
// 配置路由，BasicRoutes在RoutesManager.swift的代碼里，往下看,go go go
let basic = BasicRoutes()
server.addRoutes(Routes(basic.routes))
/* 另一種方法
* var routes = Routes()
* routes.add(method: .post, uri: "/testUpload", handler: TestUpload)
* server.addRoutes(routes)
*/
do {
try server.start() // 開啟服務(wù)器
} catch PerfectError.networkError(let err, let msg) {
print("Netword error thrown: \(err) \(msg)")
}
打開項(xiàng)目，新建RoutesManager.swift，添加以下代碼
import Foundation
import PerfectLib
import PerfectHTTP
import PerfectHTTPServer
// 路由
class BasicRoutes {
var routes: [Route] {
return [
/*
1.這里定義接口，為客戶端服務(wù)，我們請(qǐng)求的方法，和url，在這里設(shè)置。
2.由于我們還沒(méi)有新建TestUpload方法，所以這里暫時(shí)會(huì)報(bào)錯(cuò)，先不管，往下看,go go go
*/
Route(method: .post, uri: "/api/testUploadImage", handler: TestUpload)
]
}
}
新建路由助手類RoutesHelper.swift，然后添加下面代碼
import Foundation
import PerfectLib
import PerfectHTTP
let testStr = "CRTest"
/*
圖片上傳方法：
1. request是客戶端的請(qǐng)求，有些參數(shù)我們可在這里獲取
2.response是我們給客戶端的響應(yīng)，想要返回的數(shù)據(jù)，在這設(shè)置
*/

do{
guard let uploads = request.postFileUploads, uploads.count >= 1 else {
let successArray: [String:Any] = ["result":"false", "msg":"請(qǐng)選擇正確的圖片數(shù)量"]
let jsonStr = try successArray.jsonEncodedString()
try response.setBody(json: jsonStr)
response.completed()
return
}
/*
這里的iOSTime參數(shù)是我在客戶端那邊傳過(guò)來(lái)的當(dāng)前本地時(shí)間。
其實(shí)是可以在這設(shè)置的，但由于客戶端和服務(wù)器的精確時(shí)間并不一致，
