Mac之swift中系统原生请求方法的使用

import Cocoa

class ViewController: NSViewController {

override var representedObject: Any? {

didSet {

// Update the view, if already loaded.

}

//6断点续传

var downTask: URLSessionDownloadTask?

var resumeData: Data?

@IBAction func startDown(_ sender: NSButton) {

let defaultConfigObject = URLSessionConfiguration.default

let session = URLSession(configuration: defaultConfigObject, delegate: self, delegateQueue: OperationQueue.main)

let url = URL(string: "http://")

let task = session.downloadTask(with: url!)

self.downTask = task

task.resume()

}

@IBAction func stopDown(_ sender: NSButton) {

self.downTask?.cancel(byProducingResumeData: { (data) in

self.resumeData = data

})

}

@IBAction func resumeDown(_ sender: NSButton) {

let defaultConfigObject = URLSessionConfiguration.default

let session = URLSession(configuration: defaultConfigObject, delegate: self, delegateQueue: OperationQueue.main)

self.downTask = session.downloadTask(withResumeData: self.resumeData!)

self.downTask?.resume()

}

override func viewDidLoad() {

super.viewDidLoad()

//Cookie编程

//添加Cookie

let cookie = HTTPCookie(properties: [HTTPCookiePropertyKey.domain : ".reddit.com",HTTPCookiePropertyKey.path : "/"])

HTTPCookieStorage.shared.setCookie(cookie!)

//删除Cookie

if let cookies = HTTPCookieStorage.shared.cookies {

for cookie in cookies {

HTTPCookieStorage.shared.deleteCookie(cookie)

}

////1 使用系统默认的方式创建URLSession 基本流程如下

let kServerBaseUrl = "http://127.0.0.1/iosxHelper/SAPI"

func urlSessionNoDelegateTest() {

//创建一个默认的Session配置

let defaultConfigObject = URLSessionConfiguration.default

//创建URLSession，对于系统的默认的代理进行收到数据处理的情况，设置delegate参数

//为nil，同时设置代理执行的队列为主线程队列，在此也可以创建自己的私有队列

let session = URLSession(configuration: defaultConfigObject, delegate: nil, delegateQueue: OperationQueue.main)

let url = URL(string: kServerBaseUrl + "/VersionCheck")!

//构造URLRequest对象，（接口的url路径，缓存规则协议约定的策略,超时时间）

var request = URLRequest(url: url, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 30)

request.httpMethod = "POST"

request.setValue("application/x-www-form-urlencode", forHTTPHeaderField: "content-type")

let post = "versionNo=1.0&platform=Mac&channel=appstore*appName=DBAppx"

let postData = post.data(using: String.Encoding.utf8)

request.httpBody = postData

let dataTask = session.dataTask(with: request) { (data, response, error) -> Void in

let responseStr = String(data: data!, encoding: String.Encoding.utf8)

print("data = (String(describing: responseStr))")

}

dataTask.resume()

}

//2使用自定义代理方法创建URLSession

func urlSessionDelegateTest() {

//使用默认配置

let defaultConfigObject = URLSessionConfiguration.default

//创建session并设置代理

let session = URLSession(configuration: defaultConfigObject, delegate: self, delegateQueue: OperationQueue.main)

let url = URL(string: kServerBaseUrl + "/Version")!

var request = URLRequest(url: url, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 30)

request.httpMethod = "POST"

request.setValue("application/x-www-form-urlencode", forHTTPHeaderField: "content-type")

let post = "versionNo=1.0&platform=Mac&channel=appstore*appName=DBAppx"

let postData = post.data(using: String.Encoding.utf8)

let uploadTask = session.uploadTask(with: request, from: postData) { (data, response, error) -> Void in

let responseStr = String(data: data!, encoding: String.Encoding.utf8)

print("uploadTask data = (String(describing: responseStr))")

}

uploadTask.resume()

}

//3文件下载

func urlSessionDownLoadFileTest() {

let defaultConfigObject = URLSessionConfiguration.default

//创建session制定代理和任务队列

let session = URLSession(configuration: defaultConfigObject, delegate: self, delegateQueue: OperationQueue.main)

//制定下载文件的URL

let url = URL(string: "http://...png")

//创建Download任务

let task = session.downloadTask(with: url!)

task.resume()

}

//4文件上传流式文件上传客户端代码

func urlSeseionUploadFileTst() {

let uploadURL = URL(string: "http://127.0.0.1/fileUpload.php")!

var request = URLRequest(url: uploadURL)

request.httpMethod = "POST"

//要上传的路径，假设document目录下有个AppBkIcon.png文件

let uploadFileURL = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents").appendingPathComponent("ppBkIcon.png")

request.setValue("applicaiton/octet-stream", forHTTPHeaderField: "Content-type")

let defaultConfigObject = URLSessionConfiguration.default

let session = URLSession(configuration: defaultConfigObject, delegate: self, delegateQueue: OperationQueue.main)

let uploadTask = session.uploadTask(with: request, fromFile: uploadFileURL) { (data, reponse, error) -> Void in

if error != nil {

print("error (String(describing: error))")

}

uploadTask.resume()

}

//5表单文件上传

func urlSessionUploadFormFileTest() {

//服务器地址

let urlString = "http:127.0.0.1/formUpload.php"

let url = URL(string: urlString)

//上传文件的路径

let fileURL = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents").appendingPathComponent("AppBkIcon.png")

let fileName = fileURL.lastPathComponent

let fileData = try? Data(contentsOf: fileURL)

let boundary = "-bounday"

//上传的数据缓存

var dataSend = Data()

//bounary参数填充开始

dataSend.append("--(boundary) ".data(using: String.Encoding.utf8)!)

//form表单的参数

dataSend.append("Content-Disposition: form-data; name="file";filename="(fileName)" ".data(using: String.Encoding.utf8)!)

dataSend.append("Content-Type: applicaiton/octet-stream ".data(using: String.Encoding.utf8)!)

dataSend.append(fileData!)

dataSend.append(" ".data(using: String.Encoding.utf8)!)

//boundary参数填充结束

dataSend.append("--(boundary)-- ".data(using: String.Encoding.utf8)!)

//请求参数

var request = URLRequest(url: url!)

request.httpMethod = "POST"

request.httpBody = dataSend

request.setValue("multipart/form-data; boundary=(boundary)", forHTTPHeaderField: "Content-Type")

let sessionConfiguration = URLSessionConfiguration.default

let session = URLSession(configuration: sessionConfiguration, delegate: self, delegateQueue: nil)

//发起上传任务

let sessionUploadTask = session.uploadTask(with: request, from: dataSend)

sessionUploadTask.resume()

}

//服务器端php上传处理代码，脚本文件formUpload.php

// <?php

// if ($_FILES["file"]["error"] > 0)

// {

// echo "Return Code: ".$_FILES["file"]["error"]."<br />";

// }

// else

// {

// echo "Upload: ".$_FILE["file"]["name"]."<br />"

// echo "Type: ".$_FILE["file"]["type"]."<br />"

// echo "Size: ".$_FILE["file"]["size"] / 1024."kb<br />"

// echo "Temp file: ".$_FILE["file"]["tmp_name"]."<br />"

// if (file_exists("upload/". $_FILES["file"]["name"]))

// {

// echo $_FILES["file"]["name"]. "already exists.";

// }

// else

// {

// move_upload_file($_FILES["file"]["name"], "upload/". $_FILES["file"]["name"]);

// echo "Stroed in: ". "upload/". _FILES["file"]["name"];

// }

// ?>

//新建一个formUpload.html文件

// <html>

// <body>

// <form aciton="fileUpload.php" method="psot" enctype"multipart/form-data">

// <label for="file">FileName:</label>

// <input type="file" name="file" id="file" />

// <br />

// <input type="submit" name="submit" value="Submit" />

// </body>

// </html>

//将上述formUpload.php和fromUpload.html都复制到XAMPP的htdocs跟目录，完成服务端发布然后客户端测试

//缓存策略

/****

*1.userProtocolCachePolicy：协议规定的缓存策略模式使用这种策略

*2.reloadIgnoringLocalCacheData: 不适用缓存，永远适用网路数据

*3.returnCacheDataElseLoad: 适用缓存数据，不管数据是否过期，如果缓存没有数据才请求网络数据

*4.returnCacheDataDontLoad: 仅仅适用缓存数据

//7 使用实例

let kServerBaseUrl1 = "http://www.iosxhelper.com/"

func httpGetTest() {

let httpClient = HTTPClient()

let urlString = "(kServerBaseUrl1)("/VersionCheck")"

let url = URL(string: urlString)

httpClient.get(url!, parameters: nil, success: { (responseObject: Any?) -> Void in

print("get data (responseObject!)")

}) { (error: Error?) -> Void in

}

func postStringTest() {

let httpClient = HTTPClient()

let urlString = "(kServerBaseUrl1)(/VersionCheck)"

let url = URL(string: urlString)

let paras = "versionNo=1.0&platform=Mac&channel=appstore&appName=DBAppX"

httpClient.post(url!, parameters: paras, success: { (responseObject: Any?) -> Void in

print("post String responseObject = (responseObject)")

}) { (error: Error?) -> Void in

}

func postDictionaryTest() {

let httpClient = HTTPClient()

let urlString = "(kServerBaseUrl1)("/VersionCheck")"

let url = URL(string: urlString)

let paras = ["verisonNo":"1.0","platform":"Mac","channel":"appstore","appName":"DBAppX"]

httpClient.post(url!, parameters: paras, success: { (responseObject: Any?) -> Void in

print("post Dictonary responseObject =(responseObject!)")

}) { (error: Error?) -> Void in

}
