swift3.0 原生GET请求  POST同理

func getrequest(){

let url = URL(string: "http://117.135.196.139:")

var request = URLRequest(url: url!)

let list  = NSMutableArray()

var paramDic = [String: String]()

if paramDic.count > 0 {

//设置为POST请求

request.httpMethod = "GET"

//拆分字典,subDic是其中一项，将key与value变成字符串

for subDic in paramDic {

let tmpStr = "\(subDic.0)=\(subDic.1)"

list.add(tmpStr)

}

//用&拼接变成字符串的字典各项

let paramStr = list.componentsJoined(by: "&")

//UTF8转码，防止汉字符号引起的非法网址

let paraData = paramStr.data(using: String.Encoding.utf8)

//设置请求体

request.httpBody = paraData

}
