swift3.0 URLSession网络请求工具类封装(get请求,post请求)
//类名: HCTool
//单例
static let share = HCTool()
// MARK:- get请求
func getWithPath(path: String,paras: Dictionary<String,Any>?,success: @escaping ((_ result: Any) -> ()),failure: @escaping ((_ error: Error) -> ())) {
var i = 0
var address = path
if let paras = paras {
for (key,value) in paras {
if i == 0 {
address += "?\(key)=\(value)"
}else {
address += "&\(key)=\(value)"
}
i += 1
}
}
let url = URL(string: address.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)!)
let session = URLSession.shared
let dataTask = session.dataTask(with: url!) { (data, respond, error) in
if let data = data {
if let result = try? JSONSerialization.jsonObject(with: data, options: .allowFragments){
success(result)
}
}else {
failure(error!)
}
}
dataTask.resume()
}
// MARK:- post请求
func postWithPath(path: String,paras: Dictionary<String,Any>?,success: @escaping ((_ result: Any) -> ()),failure: @escaping ((_ error: Error) -> ())) {
var i = 0
var address: String = ""
if let paras = paras {
for (key,value) in paras {
if i == 0 {
address += "\(key)=\(value)"
}else {
address += "&\(key)=\(value)"
}
i += 1
}
}
let url = URL(string: path)
var request = URLRequest.init(url: url!)
request.httpMethod = "POST"
print(address)
request.httpBody = address.data(using: .utf8)
let session = URLSession.shared
let dataTask = session.dataTask(with: request) { (data, respond, error) in
if let data = data {
if let result = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) {
success(result)
}
}else {
failure(error!)
}
}
dataTask.resume()
}
例: get使用方法:
// MARK:- 请求Message数据
@objc fileprivate func loadData() {
let path = "\(totalAddress)flzxbg_service_vmessage/vmessage/getbyuserid"
let dict = ["userid":1]
HCTool.share.getWithPath(path: path, paras: dict, success: { (result) in
print(result)
}) { (error) in
print(error)
}
