////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

// move_upload_file($_FILES["file"]["name"], "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
