swift网络请求，不是第三方库，直接用代码写的，直接代码：
class fun requestDataOfGet(url: String, parameters: String?, _ callback( __ @escaping result: ant) -> ()){
let urlstr = "http://***********"//链接
let url = URL.init(string: urlstr) //需要把String的URL转换成UR
var request = URLRequset.init(url: url!)
request.httpMethod = "GET"
request.httpBody = "" //请求数据一些其他的数据，需要吧parameters转换成Data
let session = URLSession.shared
let dataTesk = session.dataTask(with: request) { (data, response, error) -> Void in
if error != nil{
print(error)
}else{
//base64 解密 对于没有加密的数据可以直接跳过
let dataStr = String.init(data: data!, encoding: String.Encoding(eawValue: String.Encoding.utf8.rawValue))
let decodedData = Data.init(base64Encoded: str!, options: Data.Base64DecodingOptions.init(rawValue: 0))
//json解析
let json = try? JSONSerialization.jsonObject(with: decodedData !, options: [])
if (json != nil) {
print(json)
}else{
print("解析失败")
}
}
//执行方法
dataTesk.resume()
}
//调用,parameters为空,若要添加,需要传入String，
ClassName.requestDataOfGet(url: url, parameters: nil){ (response) in
print(response)
//Any转换成Dictionary
guard let dataDic = response as? [String: Any] else{ return}
}
