优化：考虑get请求不传参时的参数封装

var params:Parameters = baseParams
if parameters != nil {
for (key , value) in parameters! {

2 . 调用
2.1 登录(简单json)
import SwiftyJSON
@IBAction func loginBtnTap(_ sender: UIButton) {
let phone = inputPhoneField.text!
let password = inputPasswordField.text!
if !phone.isEmpty && !password.isEmpty{
AlamofireHelper.verifityUserLogin(url: "login",username: phone,password: password, completion: {(result) in
let jsonDictory = JSON(result as Any)
let code = jsonDictory["code"].string
let msg = jsonDictory["msg"].string
print(code!+","+msg!)
if(code == "0"){
print("成功")
}else{
print("失败")
}
})
}else{
print("请输入完整信息!")
}
}
备注:
(1)登录成功返回
{"code":"0","msg":"success","res":{"status":1}}
(1)登录失败返回
{"code":"1","msg":"提示信息"}
2.2 获取并解析数据(复杂json)
var devices:[Device] = []
func getListByAlomafire() {
let params:Parameters = ["userId":"128","companyId":"50"]
AlamofireHelper.shareInstance.requestData(.post, url: "app", parameters: params) { (result) in
let jsonDictory = JSON(result as Any)
let code = jsonDictory["code"].string
let msg = jsonDictory["msg"].string
if(code == "0"){
print("成功获取设备列表:"+code!+","+msg!)
let machineList = jsonDictory["res"]["machineList"].array
for machi in machineList!{
// let machine = JSON(machi["machine"] as Any)
// let device = Device(deviceId: machine["sn"].string ?? "", deviceName: machine["name"].string ?? "", deviceStatus: machine["status"].string ?? "", deviceCount: "", deviceImage: machine["image"].string ?? "", date: machine["addTime"].string ?? "")

self.devices.append(device)
}
dump(self.devices)//打印
}else{
print("失败")
}
}
}
struct Device:Codable {
var deviceId:String
var deviceName:String
var deviceStatus:String
var deviceCount:String
var deviceImage:String
var date:String
}
